Most of what goes on inside our mouths—good or bad—is fairly predictable. But every now and then, people encounter something out of the ordinary. A good example is lichen planus.
Lichen planus are rare skin lesions that can occur on various parts of the skin, including inside the mouth. The name comes from their lacy appearance, which resembles a fungus that grows on rocks or trees called lichen.
Being similar in appearance, though, is all that lichen planus has in common with its fungal namesake. It's believed that the sores are caused by a reaction of the immune system mistaking some of the body's cells as foreign.
But don't let the exotic sounding name alarm you—true lichen planus is considered a benign mouth sore. You may not even realize you have it until your dentist notices and points it out. But the lesions can sometimes cause mild pain or burning, especially if they occur near the gums or if you indulge in spicy or acidic foods.
As we said, these lesions aren't considered dangerous. But in a small number of cases, oral cancer was found to develop later. It's unclear whether the lesions were related to the cancer, or if what were diagnosed as lichen planus lesions were actually pre-cancerous cells mimicking the appearance of the benign sore.
In any event, your dentist will probably continue to monitor the lesions and possibly conduct regular oral cancer screenings to be on the safe side. You may also want to stop using tobacco or alcohol products to further decrease your risk of oral cancer.
As to managing lichen planus, it starts with a daily habit of brushing and flossing. You'll also want to avoid spicy or acidic foods like citrus fruits, tomatoes, peppers or caffeinated drinks, especially during flareups. If the lesions are causing discomfort, your dentist may also prescribe a topical steroid to apply to them.
Since it's quite possible you won't know if you have lichen planus (as well as other types of mouth sores) unless your dentist observes them, you should keep up regular dental visits. Having your dentist check your entire mouth, not just your teeth and gums, will help both of you stay on top of your oral health.

For nearly two decades, singer-songwriter Taylor Swift has dominated the pop and country charts. In December she launched her ninth studio album, called evermore, and in January she delighted fans by releasing two bonus tracks. And although her immense fame earns her plenty of celebrity gossip coverage, she's managed to avoid scandals that plague other superstars. She did, however, run into a bit of trouble a few years ago—and there's video to prove it. It seems Taylor once had a bad habit of losing her orthodontic retainer on the road.
She's not alone! Anyone who's had to wear a retainer knows how easy it is to misplace one. No, you won't need rehab—although you might get a mild scolding from your dentist like Taylor did in her tongue-in-cheek YouTube video. You do, though, face a bigger problem if you don't replace it: Not wearing a retainer could undo all the time and effort it took to acquire that straight, beautiful smile. That's because the same natural mechanism that makes moving teeth orthodontically possible can also work in reverse once the braces or clear aligners are removed and no longer exerting pressure on the teeth. Without that pressure, the ligaments that hold your teeth in place can “remember” where the teeth were originally and gradually move them back.
A retainer prevents this by applying just enough pressure to keep or “retain” the teeth in their new position. And it's really not the end of the world if you lose or break your retainer. You can have it replaced with a new one, but that's an unwelcome, added expense.
You do have another option other than the removable (and easily misplaced) kind: a bonded retainer, a thin wire bonded to the back of the teeth. You can't lose it because it's always with you—fixed in place until the orthodontist removes it. And because it's hidden behind the teeth, no one but you and your orthodontist need to know you're wearing it—something you can't always say about a removable one.
Bonded retainers do have a few disadvantages. The wire can feel odd to your tongue and may take a little time to get used to it. It can make flossing difficult, which can increase the risk of dental disease. However, interdental floss picks can help here. And although you can't lose it, a bonded retainer can break if it encounters too much biting force—although that's rare.
Your choice of bonded or removable retainer depends mainly on your individual situation and what your orthodontist recommends. But, if losing a retainer is a concern, a bonded retainer may be the way to go. And take if from Taylor: It's better to keep your retainer than to lose it.

Forty years have passed since the first reported case of Acquired Immune Deficiency Syndrome (AIDS), and it and the human immunodeficiency virus (HIV) that causes it are still with us. About 1.2 million Americans are currently infected with HIV, with 50,000 new cases diagnosed each year.
The emergence of antiretroviral drugs, though, has made it possible for many with HIV to live normal lives. Even so, the virus can still have a profound effect on health, including the teeth and gums. Because of its effect on the immune system, HIV+ patients are at greater risk for a number of oral conditions, like a fungal infection called candidiasis ("thrush").
Another common problem is chronic dry mouth (xerostomia), caused by a lack of saliva production. Not only does this create an unpleasant mouth feel, but the absence of saliva also increases the risk for tooth decay and periodontal (gum) disease.
The latter can be a serious malady among HIV patients, particularly a severe form of gum disease known as Necrotizing Ulcerative Periodontitis (NUP). With NUP, the gums develop ulcerations and an unpleasant odor arising from dead gum tissue.
Besides plaque removal (a regular part of gum disease treatment), NUP may also require antibiotics, antibacterial mouthrinses and pain management. NUP may also be a sign that the immune system has taken a turn for the worse, which could indicate a transition to the AIDS disease. Dentists often refer patients with NUP to a primary care provider for further diagnosis and treatment.
Besides daily brushing and flossing, regular dental cleanings are a necessary part of a HIV+ patient's health maintenance. These visits are also important for monitoring dental health, which, as previously noted, could provide early signs that the infection may be entering a new disease stage.
It's also important for HIV+ patients to see their dentist at the first sign of inflamed, red or bleeding gums, mouth lesions or loose teeth. Early treatment, especially of emerging gum disease, can prevent more serious problems from developing later.
Living with HIV-AIDS isn't easy. But proper health management, including for the teeth and gums, can help make life as normal as possible.
