As we age we become more susceptible to dental diseases. A common but often initially unnoticed problem for seniors is root decay.
We’re all familiar with tooth decay in the crown, the visible tooth above the gum line. Bacteria feeding on leftover sugar in the mouth produce acid, which at high levels erodes the teeth’s protective enamel. This forms cavities and, if untreated, deeper infection within the tooth that could reach the bone via the root canals.
But decay can also directly attack a tooth’s roots below the gum line. Roots are made of dentin and covered by a very thin layer of mineralized tooth structure called cementum. Cementum, which is much softer than enamel, is often lost because of its thinness, thus exposing the root’s dentin. This can make the area more susceptible to decay than the enamel-covered crown. Normally, though, the roots also have the gums covering them as added protection against bacterial infection.
But gum recession (shrinkage), a common experience for people in their later years, can expose the root surfaces. As a result, the roots become much more susceptible to decay. And an ensuing infection could spread more quickly into the interior of the tooth than decay originating in the crown.
That’s why it’s important to remove the decayed material and fill the root cavity to prevent the infection’s spread. While similar to a crown filling, the treatment can be more difficult if the root cavity extends below the gum line. In this case, we may need to perform a surgical procedure to access the cavity.
There are other things we can do to help prevent root cavities or limit their damage. We can apply fluoride varnish to strengthen the teeth and provide extra protection against cavities, or prescribe a fluoride rinse for use at home. We can also keep an eye out and treat periodontal (gum) disease, the main cause for gum recession.
The most important thing, though, is what you do: brush and floss thoroughly each day to remove bacterial plaque and limit sugary or acidic foods in your diet. Preventing decay and treating cavities as soon as possible will help ensure you’ll keep your teeth healthy and functional all through your senior years.
Winter is the time for snowy landscapes, hot cocoa and flannel PJs, but for some 'tis the season for tooth trouble. What can you do to keep your teeth from becoming a pain this winter?
Tackle tooth sensitivity. Does crisp winter air on your teeth give you a jolt? A study published in the Journal of the American Dental Association found that 1 in 8 people (over 12%) suffer from tooth sensitivity, particularly to cold. Sensitivity can result from receding gums, erosion of tooth enamel, tooth decay or other dental problems. If you experience tooth sensitivity, use toothpaste that is specially formulated for sensitive teeth and breathe through your nose to protect your teeth from extreme cold. Most importantly, schedule a dental exam to determine why your teeth are sensitive.
Stay hydrated. In winter, we spend more time with the heat on and we tend to drink less water. A dry mouth can result, which can lead to bad breath, tooth decay and gum disease. Staying well hydrated keeps your gums and teeth moist and helps you produce more saliva, which is key to good oral health and fresh breath. Saliva helps wash away food debris and bacteria, neutralize decay-causing acid and repair weakened tooth enamel. For healthy teeth and gums, be sure to drink plenty of water this winter.
Safeguard your teeth on the slopes. Are you planning to hit the slopes this winter? Be sure to wear a mouthguard to help protect against injury. Beginning skiers and snowboarders are more likely to suffer falls that could result in dental injuries, while experts may fly over bumps and jumps, causing the upper and lower teeth to knock together with force. Even backyard sledders are at risk of dental injury. Mouthguards help protect against chipped, broken, or knocked-out teeth as well as soft tissue damage. So before you enjoy wintertime sports, make sure your teeth are protected. For the best fit and comfort, ask us about a custom mouthguard.
If you have questions about these or other dental issues, please contact us or schedule a consultation. You can learn more in the Dear Doctor magazine articles “Treatment of Tooth Sensitivity” and “Dry Mouth.”
A tooth that's been chipped doesn't mean it's no longer healthy. The same, unfortunately, can't be said about the attractiveness of your smile, especially if it's one of your front teeth. A chipped tooth can be quite noticeable and make you self-conscious.
The good news is a chipped tooth can be restored cosmetically to look just as normal and attractive as your other teeth. Depending on the application there are two different materials we commonly use: porcelains, a type of oven-fired ceramic most often found in veneers or crowns; or composite resins, a mixture of glass and plastic substances we apply in liquid form that hardens in built-up layers on the tooth's surface to ultimately resemble normal tooth shape and color.
So, which of these two materials is the best option for your tooth? That depends on the extent and location of the tooth damage. Composite resins are most often used for mild to moderate chipping or breaks in the enamel (and somewhat for the underlying dentin) or decayed areas in the front teeth. Porcelain veneers or crowns are better for more extensive damage or discoloration.
Both materials have their advantages and disadvantages. Composite resins can be applied in one office visit, but they require a skillful technique and an artistic eye to achieve a life-like appearance; although their strength has improved over the years, they're also limited in their durability and longevity compared to porcelain. Porcelain, on the other hand, is quite durable and has an excellent tooth-like appearance; they do, however, require removal of more tooth material than a composite resin to accommodate the new veneer or crown, along with more than one visit and the services of a dental lab to create the restoration.
The best way to find out which option is best for you is to visit us for a thorough dental examination. From there we can review with you our findings, our recommendations and the costs associated with each option. But whichever material we use, porcelain or composite resins, you can look forward to a new smile you'll be proud to display.
