CrackedMouthCornerscanbeIrritating-HeresHowtoTreatThem

As dentists, we often see other mouth problems besides those with teeth and gums. One of the most common is cracking around the corners of the mouth. Although usually not serious, it can be irritating and uncomfortable.

Medically known as angular cheilitis (literally “an inflammation of the angles of the lip”), it’s also called perleche, derived from the French lecher, “to lick.” The latter moniker aptly describes the tendency of sufferers to compulsively lick the sores to relieve irritation, which actually can make things worse.

Perleche has a number of possible causes, mostly from in or around the mouth (although systemic diseases or medications can cause it on rare occasions). It’s often found among younger people who drool during sleep or older people with deep wrinkles along the sides of the mouth that increase the chances of dryness and cracking. Long-term wind or cold exposure, ill-fitting dentures or a lack of back teeth (which help support facial structure) may also contribute to the condition.

Patients with perleche can also develop yeast infections from a strain called candida albicans. The infection can spread through the whole mouth, significantly increasing the chances of physical discomfort.

Treating perleche often involves topical ointments with inflammation-reducing steroids and zinc oxide, which has antifungal properties, to provide an environmental barrier during the healing process. If a yeast infection occurs, we may treat it with oral or topical antifungal medication like Nystatin for the whole mouth and chlorhexidine rinses, which has antibacterial properties.

It also helps to adopt a few preventive measures that can minimize the occurrence of perleche. If you wear dentures, for example, cleaning them often (including, if necessary, with chlorhexidine) and leaving them out at night reduces bacterial and fungal growth. We can also see if your dentures are fitting properly. Replacing missing teeth provides better facial support and could minimize wrinkling around the mouth. And, of course, keeping up daily brushing and flossing helps ensure a healthy and disease-free mouth.

If you’re experiencing cracked mouth corners, let us know at your next appointment. With our help and of other medical professionals we may be able to give you relief from this irritating condition.

RootDecayinYourLaterYearsCouldEndangerYourTeeth

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.
