The red, scaly rash suddenly appearing on your face doesn’t cause you much physical discomfort, but it’s still embarrassing. And to make matters worse treating it as you would other skin ailments seems to make it worse.
Your ailment might be a particular skin condition known as peri-oral dermatitis. Although its overall occurrence is fairly low (1% or less of the population worldwide) it seems to be more prevalent in industrialized countries like the United States, predominantly among women ages 20-45.
Peri-oral dermatitis can appear on the skin as a rash of small red bumps, pimples or blisters. You usually don’t feel anything but some patients can have occasional stinging, itching or burning sensations. It’s often misidentified as other types of skin rashes, which can be an issue when it comes to treatment.
Steroid-based ointments that work well with other skin ailments could have the opposite effect with peri-oral dermatitis. If you’re using that kind of cream out of your medicine cabinet, your rash may look better initially because the steroid constricts the tiny blood vessels in the skin. But the reduction in redness won’t last as the steroid tends to suppress the skin’s natural healing capacity with continued use.
The best treatment for peri-oral dermatitis is to first stop using any topical steroid ointments, including other-the-counter hydrocortisone, and any other medications, lotions or creams on it. Instead, wash your skin with a mild soap. Although the rash may flare up initially, it should begin to subside after a few days.
A physician can further treat it with antibiotic lotions typically containing Clindamycin or Metronidazole, or a non-prescription, anti-itch lotion for a less severe case. For many this clears up the condition long-term, but there’s always the possibility of relapse. A repeat of this treatment is usually effective.
Tell your dentist if you have recurring bouts of a rash that match these descriptions. More than likely you’ll be referred to a dermatologist for treatment. With the right attention—and avoiding the wrong treatment ointment—you’ll be able to say goodbye to this annoying and embarrassing rash.
Most of us are quite familiar with what traditional braces look like. But occasionally we see more complex-looking devices being worn by young orthodontic patients: thicker wires that extend outside the mouth, with straps that may go behind the neck or over the chin. What are these devices, and why are they sometimes needed?
In general, orthodontic appliances with external parts braced by the head, neck or chin are referred to as “headgear.” These devices may be used to handle a number of particular orthodontic situations, but they all have one thing in common: They provide the additional anchorage needed to move teeth into better positions.
It may come as a surprise that teeth, which seem so solid, can actually be moved fairly easily over time. This is because teeth are not fixed directly into bone, but are instead held in place by a hammock-like structure called the periodontal ligament. Using a light, controlled force — such as the force of springy wires and elastics in traditional braces — teeth can be moved slowly through the jaw bone, like a stick being pulled through sand.
Of course, to pull a stick through sand, you need a firm anchorage — your legs, for example, bracing against a rock. Most of the time, the back teeth, with their large, multiple roots, provide plenty of support. But sometimes, the back teeth alone aren’t enough to do the job.
If a very large space between teeth is being closed, for example, the back teeth might be pulled forward as the front teeth are pulled back; this could result in poor alignment and bite problems. In other cases, the front teeth may need to be pulled forward instead of back. The back teeth can’t help here; this is a job for headgear.
Some types of headgear have a strap that goes behind the head or neck; they use the entire head as an anchorage. Other types, called “reverse pull” headgear, have a strap that comes over the chin or the forehead; they can pull teeth forward. Headgear can even influence the proper growth of facial structures — that’s why it is usually seen on preteens, whose growth isn’t yet complete.
Headgear is usually worn for 12 hours per day, for a limited period of time. In some cases, rather than headgear, appliances called “temporary anchorage devices” (TADS) may be recommended. These are tiny screws that are implanted into the jawbone in a minimally invasive procedure, and serve a similar function.
While it may not look pretty, orthodontic headgear is capable of moving teeth into their proper positions in a relatively short period of time — and ending up with a great-looking smile is what orthodontics is all about.
