Why Seeing a “Digital Dentist” Matters

Joseph Coupal - Tuesday, October 16, 2018

Digital dentistry or dental treatment utilizing digital technology is now mainstream and part of most quality-focused dental practices. Dr. Ryne Johnson, prosthodontist and director of Newton Wellesley Dental Partners has been called a “pioneer” in the synergistic use of computer technology in implant dentistry wants you to know, “what computer technology is being used in his dental office and how”.

Digital Xrays:

    ➢ The image is immediately processed and available to view, whereas film takes time to be developed.
    ➢ Less radiation needed to produce the same quality image as film (digital X-rays gives 70% less exposure to radiation than conventional X-rays).
    ➢ You can enhance the digital image (such as alter brightness and contrast) with a series of processing techniques
    ➢ Grey-scale of digital X-rays offers 256 shades of grey versus 16-25 shades in conventional radiography, which means better diagnostics

CT Scans:

    ➢ Three dimensional imaging allows for views from many angles
    ➢ No distortion in image
    ➢ Allows for CAD/CAM diagnostics, design and planning
    ➢ Precise placement of implants – allows for “teeth in a day” approach

Digital Crowns/Impressions:

    ➢ Impressions are taken digitally via very high quality photographs.
    ➢ No ‘goop’ in your mouth for 5 minutes
    ➢ Dentistry can be fabricated via CAD/CAM technique which creates a better ‘fit’ of your work which leads to better comfort, aesthetics and longevity.
    ➢ Provides time saving for the dentist and patient

If you have yet to experience the many advantages that a technology revolution in dentistry can offer, it may be time to find a new dentist. None of this is new…time to see it for yourself!

Options in Cosmetic Dentistry for Fixing Chipped Teeth

Joseph Coupal - Monday, October 08, 2018

Newton Wellesley Dental Partners, Newton, MAMany people grind their teeth, participate in sports, and have accidents that can cause teeth to chip. This can dramatically affect your smile. In fact, According to Dr. Ryne Johnson, prosthodontist and director of Newton Wellesley Dental Partners, whom many have called Boston's Best Prosthodontist, "chipped teeth are the most common injury to teeth.

Generally, chipped teeth may not cause pain, but nevertheless, they should not be ignored. Any type of trauma to your teeth should receive immediate attention. In fact, there could be damage underneath the surface of the tooth that is chipped.  A dentist can rule out cracks or internal tooth problems that aren’t visible to the naked eye. In many cases, your chipped tooth can be repaired in just one dental visit.

There are various treatments for chipped teeth depending on the amount of damage.

Dental Bonding

Most chips can be corrected with dental bonding. Dental bonding is an efficient, durable and cost-effective way to correct minor chips.

Enamel Shaping

Often used in conjunction with dental bonding, enamel shaping can also correct small chips or surface flaws. During enamel shaping, a small portion of the tooth's surface is removed or recontoured to smooth out imperfections.

Dental Veneers

If the chip is significant and dental bonding or enamel shaping can't be used, you may need a veneer. These thin, porcelain wafers completely cover the surface of the tooth and are often used for front teeth.

Root Canal

Pain in the location of the chip can be a sign that the nerve is exposed. If that's the case, a root canal may be necessary to save the tooth, generally followed by placing a ceramic crown.

Dental Crown

A dental crown is used to completely cover larger teeth or to cap a tooth after a root canal.

Tooth Extraction

If the tooth can't be saved, a tooth extraction may be necessary. The good news is a dental bridge or dental implants can replace missing teeth.

If you are looking for a stress-free solution to replace your missing teeth and are not a candidate for an implant supported reconstruction, you may regain your confidence and achieve a beautifully radiant smile that makes you look and feel good again with a “bespoke denture”.

Many people think that dentures have been left behind in the cosmetic dental revolution, it’s not so! In fact, using the latest technology and techniques, false teeth can create the ultimate smile makeover. The latest in smile design technology can not only restore your smile but take 10 years off your whole face! Dr. Ryne Johnson, prosthodontist and director of Newton Wellesley Dental partners has the expertise and experience to completely customize your dentures to your individual desires. He delivers artistic creations that resemble a natural smile…not one that looks like ‘false teeth’.

See below…a case for a 55 year old man (both dentures are on the same patient); left photo is the denture from a mainstream dental office and ones the right are Dr. Johnson’s custom crafted dentures. The patient had been to three different offices and had three sets of dentures made before doing a set with Dr. Johnson. He reported that he could not speak, eat or “even keep them in” and was desperate for some “quality of life”.

Not only was there an aesthetic improvement, but the patient reported having a prime-rib steak dinner the weekend after inserting Dr. Johnson’s custom dentures….without any adhesive!!!


8 Everyday Habits That Harm Your Smile

Joseph Coupal - Tuesday, September 25, 2018
Newton Wellesley Dental Partners, Newton, M

Your teeth are supposed to last a lifetime. But some common habits could be reducing the durability of your teeth without you even realizing it. According to Dr. Ryne Johnson, prosthodontist and considered by many to be "Boston's Best Prosthodontist, " By recognizing the habits that can compromise the structure and health of your smile, you can take steps to protect it."

1. Avoiding Regular Dental Care

Many individuals skip regular dental cleanings or avoid getting necessary procedures due to anxiety, a lack of time, or other personal reasons. However, doing so can cause tooth decay, gum disease, and other common oral health issues.

As such, you should be sure to visit the dentist every 6 months for a professional cleaning and also, as necessary, if you notice a change or issue with your teeth.

3. Brushing Too Hard

Brushing is an essential component of good oral health, but not when done incorrectly. Brushing too hard can wear down enamel, irritate your gums, increase your teeth's sensitivity, and cause cavities.

By purchasing a soft bristled or an electronic toothbrush, you can avoid the damage while still cleaning your teeth and removing plaque.

3. Using the Wrong Materials to Clean Teeth

Have you ever had something stuck in your teeth and not had floss? If so, you might have reached for things like paper clips, toothpicks, or even pieces of paper that easily slide between your teeth. However, each of these items can cause gum and tooth damage.

You can easily resolve this problem by keeping a small container of floss or an interdental cleaner in your purse, backpack or car.

4. Grinding Your Teeth or Clenching Your Jaw

Many Americans grind their teeth or clench their jaw, which can cause fractures or other damage and may lead to headaches and jaw pain. If grinding or clenching happens while sleeping, a night guard that cushions your teeth and reduces impact on your jaw can help. If it happens during the day, chewing gum may help to prevent it.

5. Biting Your Nails, Pens, Ice, or Other Hard Objects

When you bite your nails, chew on pens, or crunch ice or even hard candy, you could be causing splinters and cracks in your teeth. But that's not all!

In fact, biting any foreign object can also introduce bacteria into your mouth and cause infections. By eliminating these bad habits, you can keep your teeth protected and eliminate additional germs in your mouth.

6. Using Your Teeth Improperly

How often do you bite open a package or try to cut something with your teeth? You may do it without thinking twice and probably more frequently than you realize.

Biting even just a thread off of your shirt could cause micro cracks that, over time, can lead to more serious structural damage. It's easy to avoid this by grabbing for a can opener, knife, or pair of scissors instead.

7. Drinking Soda, Sports Drinks, and Alcohol

While everything is acceptable in moderation, soda, sports drinks, and wine can cause significant damage when consumed in large amounts. Sports drinks and soda, which contain acid and sugar that feed bacteria and erode enamel, leave teeth susceptible to cavities.

Alcohol contains acid that produces similar effects. Additionally, because alcohol dries out the mouth, it reduces saliva production and allows bacteria and plaque to thrive.

By limiting your consumption of all of these drinks, you can do your part to keep your teeth protected.

8. Tobacco Use

If you smoke cigarettes or cigars or use chewing tobacco, you're also at risk. Nicotine not only yellows teeth, it also can cause oral cancer. Chewing tobacco is even worse because carcinogens directly contact gum tissues and can remain there for a long time.

While quitting any tobacco use is difficult, it's worth it when you consider the oral (and general) health risks of daily, or even infrequent, use.

Transform Your Everyday Habits From Harmful to Beneficial

While the habits described above are harmful, there are simple ways to correct them. Transforming destructive habits into protective measures can keep your teeth looking great for years to come. For information on improving your smile, contact Newton Wellesley Dental Partners


Dental Implants: What you Need to Know

Joseph Coupal - Wednesday, September 19, 2018
Newton Wellesley Dental Partners - Dental Implants in Wellesley, Newton, Brookline, Boston, MA

Dental implants are a good long-term solution to replacing lost teeth. According to Dr. Ryne Johnson, prosthodontist and director of Newton Wellesley Dental Partners, who has been regarded as "Boston's Best Prosthodontist", "Patients need to consider their options and make educated decisions when they are deciding between bridges and implants. The decisions you make can be the difference in one's quality of life".

1. An implant beats bridges or dentures

Bridges, dentures, and implants are all prosthetic options to replace missing teeth. A bridge requires filing two adjoining teeth, which can make them weaker and prone to decay. Dentures often have fit problems, can interfere with taste and offer a reduced chewing ability. For an implant, a titanium or zirconia screw is placed in the jawbone and a prosthetic tooth is attached. A proper implant has offers better bio-mechanical support and has good longevity.

2. Implants are more expensive generally.

One of the biggest "problems" patients see with implants is the cost. Implants are rarely covered by insurance. But when considering cost you need to consider value. Implants are a permanent, long-term solution that can match your existing teeth. Implants are generally for the rest of your life, and can replicate your teeth in appearance and functionality. If you need multiple implants or if an implant is near a nerve or sinus cavity, it's worth paying for a dentist who has specialized training.

3. Not all implants are equal

Most dentists use implants that have a long-term track record backed by in-vivo (in the mouth) studies. There are also some newer, generic implants that are cheaper but may not have been fully-evaluated yet. So ask your doctor what kind of implant he uses and the success rate he's had with it.

4. Timing can also help

Implants are usually a two-part process -- first putting in the implant, then covering it with a crown six to 12 weeks later. If you know you need one, schedule the initial procedure at the end of a calendar year, then have the dental work put on in the following year. That way you can use two years' worth of your pretax flexible spending account at work to pay a chunk of the cost. You'll reap as much as 30% savings if you're in a high tax bracket.

5. See a Specialist

There are many dentists who perform implant dentistry. However, many do not have the experience, expertise or credentials to handle the nuances that dictate whether your work looks like dentistry or looks like your natural smile. Many have only participated in a weekend continuing education program and then become self-proclaimed "experts". To assure an outstanding outcome, check one's experience, reputation and credentials. A prosthodontist, periodontist and oral surgeons all have at least 3 years of training above and beyond that of a general dentist and are committed to providing "top-shelf" care. Do your homework and your implant dentistry can last a lifetime.

Mouthwash That May Reduce Tooth Plaque

Joseph Coupal - Thursday, September 06, 2018
Newton Wellesley Dental Partners - Dental Veneers in Newton, Wellesley, Brookline, MA Soon, a mouthwash of iron oxide nanoparticles could save people a trip to the dentist. According to Dr. Ryne Johnson, prosthodontist and director of Newton Wellesley Partners, "A new research study in rats shows that such a mouthwash can thwart and stop cavities by disrupting destructive bacterial biofilms that grow on teeth".

Biofilms grown on rat tooth enamel were broken up by a combination of iron oxide nanoparticles and hydrogen peroxide.

The scientists from the University of Pennsylvania School of Dental Medicine used a formulation called ferumoxytol, which contains iron oxide nanoparticles coated with carboxymethyl dextran. Fermuoxytol is permitted by the U.S. Food & Drug Administration for treating iron deficiency.

The team planned to test the teeth-protecting abilities of these iron oxide nanoparticles because they can break down hydrogen peroxide to develop hydroxyl radicals that can disturb biofilms. The study tested mouthwash therapy involving solutions of ferumoxytol and hydrogen peroxide. They used nanoparticle doses that were below 1% of what is used to treat iron-deficiency.

Over a period of three weeks, the scientists used both solutions twice a day to rinse the mouths of rats with cavities that mimic extreme childhood dental decay. In contrast to animals that did not get the mouthwash, treated rats saw substantial improvements in their dental decay. The mouthwash both stopped the progression of current damage and stopped damage to smooth, healthy teeth.

The method holds promise. In most cases, the only effective way of eradicating a biofilm is physical removal of the infected biomaterial. What’s interesting about this work is the ability of the developed nanoparticles to degrade the biofilm matrix from within.

The health of our teeth and oral cavity is highly dependent on the community of good bacteria living in our mouth. Any nonspecific antibacterial treatment will inevitably affect our good bacteria.

The team is currently involved in developing formulations with higher catalytic activity, and ultimately aims to test the effectiveness of the mouthwash in humans. For outstanding dental care, that is focused on cutting edge techniques and services, contact Dr. Johnson at Newton Wellesley Dental Partners.

Porcelain Veneers or Dental Crowns?

Joseph Coupal - Tuesday, August 28, 2018
Newton Wellesley Dental Partners - Dental Veneers in Newton, Wellesley, Brookline, MA

Today people have more options to choose from when it comes to cosmetic dentistry procedures. Dr. Ryne Johnson, prosthodontist and director of Newton Wellesley Dental Partners, has been the 'go-to' dentist for Boston's most demanding patients. According to Dr. Johnson, "For broken, missing, misaligned and uneven teeth, the two most common cosmetic dental procedures are dental veneers and dental crowns".

What is the difference?

Generally, what determines whether you need veneers or crowns is the condition of your teeth and what you are trying to accomplish or ‘fix’ with the procedure. The basic difference between crowns and veneers is how much of the tooth they cover. Dental veneers cover the front of the tooth. A dental crown covers the entire tooth. So, while they are both used for aesthetics and function, they have different applications.

Crowns are used on a damaged tooth or for a tooth that needs more strength and protection. Veneers are used on teeth that are healthy, but may be stained, crooked, short, have spaces between them.

Dental crowns are shaped like your real tooth and they are designed to match your teeth’s natural color. The tooth that it is covering will be reduced in size, and the crown fits perfectly on top of it. Crowns will function and be as durable as your natural tooth. Crowns are perfect to fix teeth that are used for chewing, or for those who clench or grind their teeth.

Porcelain veneers are thin shells that are secured to the side of the tooth that shows when you smile. Porcelain veneers are used on patients who want to improve the shape, color, spacing, or crowding of their teeth.

When choosing a restorative dentist for demanding aesthetic cases, the ceramist used by the dentist is as, if not more important then the office you select. Reputation does matter in this regard....remember to see a specialist, the difference will make you smile.

Dental Implants: Are They the Right Treatment for You?

Joseph Coupal - Wednesday, August 22, 2018
Newton Wellesley Dental Partners - Dental Implants in Wellesley, Newton, Brookline, Boston, MA

Dental implants are one of the most common and long lasting treatments for replacing missing teeth. Dr. Ryne Johnson, prosthodontist and director of Newton Wellesley Dental Partners has been a pioneer in implant dentistry since 1986. He is know for his synergistic use of computers in dental implant reconstructions. Via the combination of CT Scans, placement jigs and CAD/CAM technology, Dr. Johnson and his in-house periodontist are able to diagnose, design and place implants to support sophisticated dental reconstructions in one visit. The "All On Four Technique" has transformed patients lives and is a routine part of Dr. Johnson's repertoire. According to Boston's best prosthodontist, "Dental implants function similarly to a real tooth by replacing the missing tooth with an artificial tooth and root. In this process, the root of the tooth is replaced with a titanium screw. It is inserted into the jawbone and attached with an artificial tooth or a dental prosthesis".

The natural appearance of dental implants is one of its greatest advantages. They look very similar to natural teeth and work better than bridges and dentures. They do not rely on the cement seal between tooth and the dental work and have extraordinary anchorage. Compared to other treatments for replacing missing teeth, dental implants have a significantly more-natural appearance and generally a better long-term prognosis.

Dental implants are easy and a more convenient solution than other options for most patients. They can also be used as a support for dentures because the titanium root is securely screwed into the jaw. Today, most dentists are choosing implants to replace missing teeth and enhance overall appearance.

Though dental implants are more expensive than other treatment options, they can last a lifetime when properly cared for, making them very cost effective. They offer the best "quality of life" in terms of function and longevity. If you are considering dental implants, Dr. Johnson recommends that you see a specialist for the best outcome, "Many dentists are taking a weekend continuing education course and project themselves as experts. Four the best outcome, check one's experience, credentials and reputation before initiating care". For one or more missing teeth, consider dental implants for a younger, healthier, more natural appearance.

Older Americans Who Neglect Dental Care put Overall Health at Risk

Joseph Coupal - Monday, August 13, 2018
Newton Wellesley Dental Partners, Newton, Brookline, Wellesley, MA

Conscientious parents constantly remind their children to brush and floss and routinely schedule dental checkups to make sure their teeth and gums are healthy and staying that way. But youngsters aren’t the only ones who can use such reminders. Dr. Ryne Johnson, prosthodontist and director of Newton Wellesley Dental Partners says, "Older Americans need to put a priority on their oral health as well, and research shows that as a group they aren’t doing so".

In fact, the statistics are grim. The Centers for Disease Control and Prevention reports that almost every single American over age 65 (96 percent) has had a cavity, and 20 percent have untreated tooth decay. Another 65 percent suffer from gum disease, an ailment that has been linked to a host of other problems, such as strokes, heart disease, and diabetes.

Anyone who thinks they can ease up on dental care as they age is making a big mistake. Not only do poor dental habits affect what’s going on in your mouth, they also affect your overall health.

Older Americans who neglect oral care put overall health at risk, and some of the CDC’s findings are troubling.

Tooth loss

Nearly one in five adults aged 65 or older has lost all of his or her teeth. Complete tooth loss is twice as prevalent among adults aged 75 and older (26 percent) compared with adults aged 65 to 74 (13 percent). The CDC points out that having missing teeth or wearing dentures can have a detrimental effect on nutrition. It’s not surprising that people who have lost teeth, or wear denture, often are going to choose soft foods that they can chew easily. They will pass up fresh fruits and vegetables that are more nutritious but also more difficult for them to eat.

Oral cancer

Cancers of the mouth (oral and pharyngeal cancers) are primarily diagnosed in older adults, and the median age at diagnosis is 62 years. That’s another reason it’s important for older people to have regular checkups. Your dentist can check for signs of oral cancer during those visits.

Dry mouth caused by medications

Most older Americans take both prescription and over-the-counter drugs, many of which can cause dry mouth. Reduced saliva flow increases the risk of cavities. Saliva helps prevent tooth decay, gum disease, and bad breath and also lubricates the mouth, making it easier to eat, swallow, speak, and taste food. Sometimes, dry mouth might just cause mild discomfort. At other times, it can lead to significant oral disease that can compromise the person’s health, dietary intake, and quality of life.

As you age, proper oral care is just as important as ever. It’s not something you want to ignore because your overall health is at stake.
