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.

A lot of time and effort goes into straightening your smile. But there’s a possibility it might not stay that way—and all that hard work could be lost. The same natural mechanism that enables your teeth to move with braces could cause them to revert to their old, undesirable positions.
So for a little while (or longer for some people) you’ll need to wear a retainer, an appliance designed to keep or “retain” your teeth where they are now. And while the removable type is perhaps the best known, there’s at least one other choice you might want to consider: a bonded retainer.
Just as its name implies, this retainer consists of a thin metal wire bonded to the back of the teeth with a composite material. Unlike the removable appliance, a bonded retainer is fixed and can only be removed by an orthodontist.
Bonded retainers have several advantages. Perhaps the most important one is cosmetic—unlike the removable version, others can’t see a bonded retainer since it’s hidden behind the teeth. There’s also no keeping up with it—or losing it—since it’s fixed in place, which might be helpful with some younger patients who need reminding about keeping their retainer in their mouth.
There are, however, a few disadvantages. It’s much harder to floss with a bonded retainer, which could increase the risks of dental disease. It’s also possible for it to break, in which case it will need to be repaired by an orthodontist and as soon as possible. Without it in place for any length of time the teeth could move out of alignment.
If you or a family member is about to have braces removed, you’ll soon need to make a decision on which retainer to use. We’ll discuss these options with you and help you choose the one—removable or bonded—that’s right for you.

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.
Is having good oral hygiene important to kissing? Who's better to answer that question than Vivica A. Fox? Among her other achievements, the versatile actress won the “Best Kiss” honor at the MTV Movie Awards, for a memorable scene with Will Smith in the 1996 blockbuster Independence Day. When Dear Doctor magazine asked her, Ms. Fox said that proper oral hygiene was indeed essential. Actually, she said:
"Ooooh, yes, yes, yes, Honey, 'cause Baby, if you kiss somebody with a dragon mouth, my God, it's the worst experience ever as an actor to try to act like you enjoy it!"
And even if you're not on stage, it's no fun to kiss someone whose oral hygiene isn't what it should be. So what's the best way to step up your game? Here's how Vivica does it:
“I visit my dentist every three months and get my teeth cleaned, I floss, I brush, I just spent two hundred bucks on an electronic toothbrush — I'm into dental hygiene for sure.”
Well, we might add that you don't need to spend tons of money on a toothbrush — after all, it's not the brush that keeps your mouth healthy, but the hand that holds it. And not everyone needs to come in as often every three months. But her tips are generally right on.
For proper at-home oral care, nothing beats brushing twice a day for two minutes each time, and flossing once a day. Brushing removes the sticky, bacteria-laden plaque that clings to your teeth and causes tooth decay and gum disease — not to mention malodorous breath. Don't forget to brush your tongue as well — it can also harbor those bad-breath bacteria.
While brushing is effective, it can't reach the tiny spaces in between teeth and under gums where plaque bacteria can hide. But floss can: That's what makes it so important to getting your mouth really clean.
Finally, regular professional checkups and cleanings are an essential part of good oral hygiene. Why? Because even the most dutiful brushing and flossing can't remove the hardened coating called tartar that eventually forms on tooth surfaces. Only a trained health care provider with the right dental tools can! And when you come in for a routine office visit, you'll also get a thorough checkup that can detect tooth decay, gum disease, and other threats to your oral health.
Bad breath isn't just a turn-off for kissing — It can indicate a possible problem in your mouth. So listen to what award-winning kisser Vivica Fox says: Paying attention to your oral hygiene can really pay off! For more information, contact us or schedule an appointment for a consultation.

Although periodontal (gum) disease usually affects your gums first, your teeth may eventually suffer. That’s because the disease can damage both attaching gum tissues and supporting bone.
One advanced sign of this is when one or more teeth become loose. A loose tooth is an alarm bell that you’re about to lose it.
Fortunately, we can often treat loose diseased teeth with a two-phase approach. First and foremost, we need to bring the gum infection under control by removing plaque and calculus (tartar) — the “fuel” for the infection — from all tooth and gum surfaces. Depending on how extensive it is, we have options: we can use specially designed hand instruments to remove plaque and calculus, ultrasonic equipment that loosens and flushes plaque and calculus away, or, if necessary, conventional or laser surgery.
Depending on the extent of the infection, in some cases we may need to use regenerative surgical techniques like gum and bone grafting to replace lost tissue. Healing takes time, though, which leads to the second phase of treatment — securing the loose tooth during gum healing.
The most common way is through a bite adjustment, where teeth are altered to equilibrate chewing forces evenly. This results in all the teeth being hit at the same time allowing the loose teeth to heal and tighten up.
Another option is splinting teeth together. Although there are different methods, the basic idea is to join the loose teeth with stable teeth like pickets in a fence. One way is to bond splinting material across the back surfaces of the involved teeth. Another way is to cut in a small channel across the teeth and insert and bond a rigid strip of metal to splint the teeth in place.
The splint is usually a temporary measure while the gums heal. In some situations, though, we may need to perform a permanent splint by crowning the affected teeth and then splinting the crowns together. If you have a grinding habit we may also prescribe a night guard to limit the damage done while you sleep.
Before deciding on which technique is best for you, we would first need to evaluate the health of the affected teeth to see whether the effort would be worth it. It could be the tooth’s supporting bone structure has become so deteriorated that it might be better to extract the tooth and consider an implant or other replacement. First, though, we would attempt if at all practical to save the tooth — and the sooner we begin treating it, the better your chances for such an outcome.
