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.
Have you ever felt a hot, burning sensation in your mouth—like it had been scalded—but you didn't eat or drink anything that could have caused it?
While you may think you’re hallucinating, there’s another possibility: Burning Mouth Syndrome (BMS). This condition, which can last for years, produces sensations in the mouth of not only scalding or burning, but also tingling, numbness and a decline in your ability to taste. Patients may feel it throughout their mouth or only in localized areas like the lips, tongue or inside the cheeks.
The exact cause of BMS is also something of a mystery. It’s been theoretically linked to diabetes, vitamin or mineral deficiencies and psychological problems. Because it’s most common among women of menopausal age hormonal changes have been proposed as a factor, although hormone replacement therapy often doesn’t produce any symptomatic relief for BMS.
To complicate matters, other conditions often share the condition’s effects, which need to be ruled out first to arrive at a BMS diagnosis. A feeling of scalding could be the result of mouth dryness, caused by medications or systemic conditions that inhibit saliva flow. Some denture wearers may display some of the symptoms of BMS due to an allergic reaction to denture materials; others may have a similar reaction to the foaming agent sodium lauryl sulfate found in some toothpaste that can irritate the skin inside the mouth.
If these other possibilities can be ruled out, then you may have BMS. While unfortunately there’s no cure for the condition, there are ways to lessen its impact. There’s even the possibility that it will resolve itself over time.
Until then, keep your mouth moist by drinking lots of water or using saliva-stimulating products, limiting alcohol, caffeinated drinks or spicy foods and refraining from smoking. If you’re taking medications that could cause dry mouth, speak with your physician about changing to an alternative. And try to reduce stress in your life through exercise, mindfulness practices or support groups.
While BMS isn’t considered harmful to your physical health it can make life less enjoyable. Careful symptom management may help improve your quality of life.
