Can Gum Disease Affect Ovulation?

According to Dr. Ryne Johnson, prosthodontist and managing partner at Newton Wellesley Dental Partners, “Women struggling to get pregnant need to take good care of their gums, a study has found. Bacteria that causes gum infections appears to have a role in making conception take longer”.  According to a recent study, “Women with bacteria that causes gum disease in their saliva, P. Gingivalis, took three times longer to get pregnant than women without. And women with the bug as well as symptoms of periodontitis - disease of the gum and underlying bone - took four times longer”. Researchers believe that infection in the gums and jawbone leads to further inflammation in the body. This inflammation may prevent ovulation or could stop the embryo implanting. Women struggling to get pregnant need to take good care of their gums, a study has found. Researchers think gum disease might be a warning sign of problems elsewhere in the body - particularly type two diabetes and heart disease”. Additionally, post-menopausal women are more likely to die early if they have gum disease according to this study.  Women who lose teeth after the menopause are at a higher risk of an early death, experts have warned. A major study suggests gum disease and tooth loss is a red flag for severe health problems. Study leader Dr Michael LaMonte, of the University at Buffalo in New York, said no matter the cause of the link, more intensive dental screening in old age could help nip problems in the bud. Other possible effects are inflammation interfering with hormone production, as well as contributing to endometriosis, a condition where tissue that normally grows inside the womb grows elsewhere in the body.  Dr Susanna Paju, of the University of Helsinki said: ‘Our study does not answer the question on possible reasons for infertility but it shows that periodontal bacteria may have a systemic effect even in lower amounts, and even before clear clinical signs of gum disease can be seen. Thus, Dr. Johnson suggests that, “results encourage young women of fertile age to take care of their oral health and attend periodontal evaluations regularly”. How the study was carried out: Researchers at the University of Helsinki studied 256 healthy non-pregnant women aged between 19 and 42 who had stopped contraception and were trying to get pregnant. The health of their mouths and gums, as well as their reproductive organs, were examined.  Over 12 months they were observed as to whether they became pregnant or not.  Researchers believe gum infection leads to further inflammation that may prevent ovulation.   Key findings : Gingivalis Bacteria was ‘significantly more frequently detected in the saliva among women who did not become pregnant during the one-year follow-up period than among those who did.’ The research found women who either had P. Gingivalis in their saliva – or antibodies indicating they had been infected by P Gingivalis, were three times less likely to get pregnant, while those with the bacteria and signs of gum disease were four times less likely to get pregnant. The bacteria remained a factor even after other factors that have an effect on getting pregnant such as socioeconomic status, general health and smoking were considered.

Dental Problems Related to Scuba Diving – Newton, Wellesley, MA

A new survey of recreational scuba divers finds that 41 percent report dental problems related to diving. Most of the problems had to do with pain from the increased pressure underwater or from clutching the air regulator too tightly in their mouths, but a few people experienced loosened crowns or cracked fillings.  ryneDr. Ryne Johnson,  prosthodontist and managing partner of Newton Wellesley Dental Partners reports that, “over my 30 years in clinical practice, I have seen numerous patient who presented with broken or shifted teeth induced by long-time use of a regulator”.  He further recommends, “The survey was limited, but suggests that people should make sure their teeth are in good shape before they go deep.  An unhealthy tooth underwater would be much more obvious than on the surface.  One hundred feet underwater is the last place you want to be with a fractured tooth."

Underwater toothache

Barodontalgia is a toothache caused by the increase in pressure felt underwater (it can also happen at high altitudes because of low pressure). The condition, which occurs while the person is in the high- or low-pressure environment, is most common in people who have some sort of underlying dental condition, like a cavity or poorly completed filling.  project1

Forty-one percent of respondents of a recent study said they'd experienced dental symptoms while diving. Of those, 42 percent said they'd had barodontalgia. The second-most common symptom was pain from holding the air regulator too tightly (24 percent of those who'd had a dental symptom), and the third-most common problem was jaw pain (22 percent of those who'd had a dental symptom).

Protecting your teeth

Several people reported that a dental crown — a cap that fits over a broken or damaged tooth — had loosened during a dive. One person reported a broken filling.  The dry air and awkward position of the jaw while clenching down on the regulator is an interesting mix. Dive instructors reported more pain and problems than casual divers.  Instructors spend more time at shallower diving depths, where the changes in pressure are most abrupt.

Divers are required to meet a standard of medical fitness before certification, but there are no dental health prerequisites," according to Dr. Johnson.  In the meantime, divers can protect themselves by visiting the dentist before scuba diving to check for decay and other problems.

Teeth Grinding & Stress – Newton, Wellesley, MA

Research has found a link between stress and teeth grinding, which 70 percent have reported. Known as bruxism, teeth grinding can go undetected as the most common symptom is a headache, usually concentrated at the temples of the head. Other symptoms include sleep disorders, ear ache, and stiff muscles in the jaw, shoulders and neck. The teeth will also show signs of wear, cracks and tooth loss can result.

Dr. Ryne Johnson, prosthodontist and managing partner at Newton Wellesley Dental Partners has been treating teeth grindinryneg and TMJ therapy for over thirty years.  “Many people grind their teeth at night and we used custom-made, hard appliances (with a softer, resilient liner) to lessen the impact of this significant force” says Johnson.  “The night guard is designed to absorb the impact and spread the force out over all the teeth instead of allowing it to wear away the enamel”.

What the doctor says:  'If you suspect that you are suffering from Bruxism, it is important to see your dentist who can provide a proper diagnosis”.

“Grinding your teeth can be triggered by several factors project1including an underlying sleep disorder, stress and anxiety or a result of dietary intakes such as alcohol and caffeine”.

“Your dentist will recommend a guard specially made for your teeth to create a protective barrier from friction to prevent increased tooth wear and reduce discomfort of the jaw muscles.”

Digital Dentistry Impacts Hollywood – Newton, Wellesley, MA

Digital models of humans can be uncannily accurate these days, but there's at least one area where they fall short: teeth. Unless you're willing to scan the inside of someone's mouth, you aren't going to get a very faithful representation of someone's pearly whites.ryneDr. Ryne Johnson, a prosthodontist and managing partner of Newton Wellesley Dental Partners has been considered a pioneer in the use of CAD/CAM technology in dental restorations. He notes that, “Disney Research and ETH Zurich have just developed a technique to digitally recreate teeth beyond the gum line using little more than source data and everyday imagery. The team used 86 3D scans to create a model for an "average" set of teeth, and wrote an algorithm that adapts that model based on what it sees in the contours of teeth in photos and videos.  Unlike the $40,000 CAD/CAM unit that’s used in my office, this new approach allows sufficient accuracy to be captured from regular digital photographs”.

The technology doesn't require any special capture equipment outside of the initial scans (the camera on your phone will do). Also, you don't have to purposefully bare your teeth: it can work with the incomplete information from a smile or grimace. A movie crew could generate models based on a brief, natural motion capture session.project1

This being Disney, the most obvious use is for digital actor models in animated movies and video games. You could see uncannily realistic characters whose details pass muster even in close-up shots. However, there are plenty of medical uses as well. The scientists see dentists using the tech to previsualize a patient's mouth before they sit in the operating chair, and it's easy to imagine this leading to more authentic-looking dentures. As silly as the notion of accurately rendered teeth may be, they could be important for your well-being.

Dr. Johnson feels that this new technology will help the film and media production companies but will not be incorporated into a dental office any time soon.  However, he reminds everyone that, “digital dentistry is here and should be a part of your dental reconstructive and implant work”.

The Latest on Teeth Whitening

Dr. Ryne Johnson, prosthodontist and managing partner of Newton Wellesley Dental Partners was recently interviewed for a national magazine that was developing a synopsis of cosmetic dental procedures.  According to Dr. Johnson, “Tooth whitening has become one of the most frequently requested dental procedures in his office. The public has come to demand whiter, more perfect smiles and in response many choices for tooth whitening have been made available. These include home-based products such as toothpastes, gels, and films, as well as in-office based systems where products containing highly concentrated bleaching agents are applied under professional supervision". The profession and public have been aware of certain risks related to tooth whitening such as increased tooth sensitivity and gingival irritation. New research has shown that there are other risks such as tooth surface roughening and softening, increased potential for demineralization, degradation of dental restorations, and unacceptable color change of dental restorations. The new research is also focused on optimizing whitening procedures to reduce tooth sensitivity and to increase the persistence of the whitening.   Types of Teeth Whitening Systems Whitening systems can be variously categorized. The following approach is in accordance with the American Academy of Cosmetic Dentistry. Whitening Toothpastesproject1 Whitening toothpastes typically contain higher amounts of abrasives and detergents than standard toothpastes, to remove tougher stains. Whitening toothpastes do not contain bleach (sodium hypochlorite) but some contain low concentrations of carbamide peroxide or hydrogen peroxide that help lighten tooth color. Whitening toothpastes typically can lighten tooth color by about one or two shades. OTC Whitening Strips and Gels Whitening strips were introduced into the market in the late 1980’s. They deliver a thin layer of peroxide gel on plastic strips shaped to fit onto the buccal surfaces of the teeth. There are a variety of white strip products on the market with varying instructions. A typical set of instructions are to apply the strips twice daily for 30 minutes for 14 days. project2Tooth lightening can be seen in several days and this method can lighten the teeth by 1 or 2 shades. There are some newer whitening strip products that require only one 30-minute application per day that have the same whitening end point as the two-a-day products. Whitening gels are peroxide-based gels applied with a small brush directly to the surface of the teeth. Manufacturer’s instructions are usually twice a day applications for 14 days. Like the whitening strips, the teeth can usually be lightened by 1 or 2 shades. Whitening Rinses Whitening rinses contain oxygen sources such as hydrogen peroxide to react with the chromogens.project3 Manufacturer’s instructions are for twice a day rinsing for 60 seconds each. It takes up to 3 months to see a 1 or 2 shade improvement in tooth color. Tray-Based Tooth Whiteners Tray-based tooth whitening systems are available both professionally and OTC. This method involves use of a fitted tray containing carbamide peroxide-bleaching gel worn fproject4or 2 to 4 hours a day or overnight. Usually by following the manufacturer instructions tooth whitening is noticeable in a few days, lightening the teeth by 1 or 2 shades. In-Office Whitening Quicker tooth lightening can be achieved through in-office whitening because the products deliver higher concentrations of peroxide than OTC. Consequently, gingival tissues are usually protected before the agent is applied. Some products claim to increase the oxidation of chromogens by exposure to heat or an intense blue light with a wave length between 480 nm and 520 nm to activate the product while on the tooth, causing the chemical reactions to proceed faster. Some professionals use laser systems to increase the rate of the chemical reactions. This use of lasers is considered to be an ‘off-label’ use of laser systems in dentistry by the US Food and Drug Administration. In a systematic review by Buchalla and Attin no added benefit from light-activated systems was found and thus the American Dental Association does not endorse such whitening systems.project5 Tooth lightening results are seen after one 30- to 60-minute treatment. More dramatic results can be obtained with several applications. Risks associated with Tooth Whitening Risks commonly reported with tooth whitening include increased tooth sensitivity and mild gingival irritation. The degree of these side effects is directly related to the concentration of the peroxide bleach component, duration of the treatment, and the non-bleach composition of the product used. Tooth sensitivity usually occurs at the time of treatment and can last several days; gingival irritation begins within a day of the treatment and can also last several days. There are additional risks that have been reported from in vitro studies which include tooth erosion, tooth mineral degradation, increased susceptibility to demineralization, and pulpal damage.4 The ultimate endpoint for tooth whitening is dependent upon the tooth itself, with common wisdom telling us that all treatment regimens will eventually arrive at the same whitening endpoint. This is not exactly true as some very aggressive regimens can damage the tooth through dehydration and demineralization such that the tooth temporarily appears whiter.   Dr. Ryne Johnson, who first lectured on tooth whitening procedures in 1989, has helped thousands of patients achieve a more beautiful smile, often incorporating this proven technique.
