ThoseRedPatchesonYourTongueareNothingtobeAlarmedAbout

If you've ever been alarmed to find oddly-shaped red patches on your tongue, you can relax for the most part. Most likely, you're part of a small fraction of the population with a condition known as geographic tongue.

The name comes from the irregular shape of the patches that seem to resemble land formations on a map. Its medical name is benign migratory glossitis, which actually describes a lot about the condition. The patches are actually areas of inflammation on the tongue (“glossus” – tongue; “itis” – swelling) that appear to move around or migrate. They're actually made up of areas where the tiny bumps (papillae) you normally feel have disappeared: the patches feel flat and smooth compared to the rest of the tongue.

We're not sure why geographic tongue occurs. It often runs in families and seems to occur mostly in middle-aged adults, particularly women and non-smokers. It's believed to have a number of triggers like emotional stress, hormonal disturbances or vitamin or mineral deficiencies. There may also be a link between it and the skin condition psoriasis. Under a microscope the red patchiness of both appears to be very similar in pattern; the two conditions often appear together.

The bad news is we can't cure geographic tongue. But the good news is the condition is benign, meaning it's not cancerous; it's also not contagious. It poses no real health threat, although outbreaks can be uncomfortable causing your tongue to feel a little sensitive to the touch with a burning or stinging sensation. Some people may also experience numbness.

Although we can't make geographic tongue go away permanently, you should come by for an examination to confirm that is the correct diagnosis. Once we know for sure that you do have migratory glossitis, we can effectively manage discomfort when it flares up. You should limit your intake of foods with high acidity like tomatoes or citrus fruits, as well as astringents like alcohol or certain mouthrinses. We can also prescribe anesthetic mouthrinses, antihistamines or steroid ointments if the discomfort becomes more bothersome.

It may look strange, but geographic tongue is harmless. With the right care it can be nothing more than a minor annoyance.

AreYouintheKnowAboutDentalCrownsTakeourTrueorFalseQuiz

So, you're about to have a tooth capped with a crown. Do you know what you need to know before you undergo this common dental procedure?

Here's a short true or false quiz to test your knowledge of dental crowns.

All crowns are the same. False — while all crowns have the same basic design — a life-like prosthetic tooth fitted over and bonded or cemented to a natural tooth — their compositions can vary greatly. Early metal crowns consisted mainly of gold or silver and are still used today. Porcelain-fused-to-metal (PFM) crowns — a metal interior for strength overlaid by a porcelain exterior for appearance — became popular in the latter 20th Century. Although still widely used, PFMs have been largely surpassed by newer all-ceramic materials that are stronger than past versions.

Crowns can differ in their artistic quality. True — all crowns are designed to replicate a natural tooth's function — in other words, enable the tooth to effectively chew again. But a crown's appearance can be a different story, depending on how much attention to detail and artistry goes into it. The higher the individual craftsmanship, the more lifelike it will appear — and the more expensive it can be.

With digital milling equipment, dental labs are obsolete. False — although technology exists that allows dentists to produce their own crowns, the equipment is not yet in widespread use.  The vast majority of crowns are still produced by a trained technician in a dental laboratory. And just as you base your choice of a dentist on your confidence in and respect for them, dentists look for the same thing in a dental lab — good, reliable and consistent results.

Your insurance may not cover what your dentist recommends. True — dental insurance will typically pay for a basic, functional crown. Aesthetics — how it will look — is a secondary consideration. As a result, your policy may not cover the crown your dentist recommends to function properly and look attractive. A new crown, however, is a long-term investment in both your dental function and your smile. It may be well worth supplementing out of pocket your insurance benefit to get the crown that suits you on both counts.

SingerDuaLipaSeestheWisdominPostponingTourDates

When die-hard music fans hear that their favorite performer is canceling a gig, it’s a big disappointment—especially if the excuse seems less than earth-shaking. Recently, British pop sensation Dua Lipa needed to drop two dates from her world tour with Bruno Mars. However, she had a very good reason.

“I’ve been performing with an awful pain due to my wisdom teeth,” the singer tweeted, “and as advised by my dentist and oral surgeon I have had to have them imminently removed.”

The dental problem Lipa had to deal with, impacted wisdom teeth, is not uncommon in young adults. Also called third molars, wisdom teeth are the last teeth to erupt (emerge from beneath the gums), generally making their appearance between the ages of 18-24. But their debut can cause trouble: Many times, these teeth develop in a way that makes it impossible for them to erupt without negatively affecting the healthy teeth nearby. In this situation, the teeth are called “impacted.”

A number of issues can cause impacted wisdom teeth, including a tooth in an abnormal position, a lack of sufficient space in the jaw, or an obstruction that prevents proper emergence. The most common treatment for impaction is to extract (remove) one or more of the wisdom teeth. This is a routine in-office procedure that may be performed by general dentists or dental specialists.

It’s thought that perhaps 7 out of 10 people ages 20-30 have at least one impacted wisdom tooth. Some cause pain and need to be removed right away; however, this is not always the case. If a wisdom tooth is found to be impacted and is likely to result in future problems, it may be best to have it extracted before symptoms appear. Unfortunately, even with x-rays and other diagnostic tests, it isn’t always possible to predict exactly when—or if—the tooth will actually begin causing trouble. In some situations, the best option may be to carefully monitor the tooth at regular intervals and wait for a clearer sign of whether extraction is necessary.

So if you’re around the age when wisdom teeth are beginning to appear, make sure not to skip your routine dental appointments. That way, you might avoid emergency surgery when you’ve got other plans—like maybe your own world tour!
