WhatsattheRootofToothSensitivity

In a healthy tooth, a coating of enamel protects the crown — the part above the gum line — and a layer of cementum protects the tooth root below the gum line. Enamel and cementum are inert (nonliving) substances that do not respond to stimuli such as heat or cold; however, dentin, the living tissue below them, does. Dentin contains numerous microscopic tubules that readily transmit stimuli toward the nerve-filled center of the tooth (pulp tissue). Loss of protective enamel or cementum leaves dentin exposed to all sorts of stimuli in the oral environment, which can trigger “dentinal hypersensitivity” — anything from a mild twinge to shooting pain.

Fortunately, there are many options for treating hypersensitivity. The key to selecting the most appropriate one(s) is determining the cause(s). Some of the more common reasons for sensitivity due to dentin exposure include:

  • Enamel erosion caused by an “acid attack” related to external (extrinsic) causes — i.e., consumption of acidic beverages/food — or internal causes — i.e., regurgitation of stomach acids due to gastroesophageal reflux disease [GERD] or the eating disorder bulimia
  • Using an overly abrasive brush or toothpaste, brushing incorrectly or too frequently, or brushing too soon after an “acid attack” — all of which can result in a loss of enamel
  • Tooth decay (dental caries or cavities)
  • Tooth fracture or chipping: tooth grinding (bruxism) is a common cause
  • Worn fillings
  • Gum recession, due to age or improper tooth brushing, that exposes the tooth root
  • Gum disease, which can result in gum recession

Sensitivity can also occur following a procedure like treating a cavity. Normally it subsides within a couple of weeks or so but if it continues there may be another underlying cause.

If you haven't seen a recent picture of Matthew Lewis, the actor who played Neville Longbottom in all eight Harry Potter movies, you may be in for a surprise: It seems the plump, awkward teenager from Gryffindor has been magically transformed into a post-Hogwarts hunk. What kind of wizardry did it take to change his memorably snarled teeth into a leading man's sparkly smile? The kind skilled cosmetic dentists perform every day!

While special effects created some of the character's dental disarray, the actor's own teeth were far from perfect. And, as Lewis recently noted, the film studio urged him to postpone cosmetic dental work until the movies were all done. “It was something I'd always wanted to do, but it would have meant me wearing a brace for two years,” he told an interviewer with the Yorkshire Evening Post. “Warner Brothers said if I put it off until we'd finished filming they'd pay for it — and they did.”

There are plenty of people, like the twenty-something actor, who put off orthodontic treatment until after their teen years. If you're wondering whether there's still time to get orthodontic work done, then take heart — it's never too late to straighten your teeth!

Today, an estimated twenty percent of orthodontic patients are adults. Compliance with the orthodontic program (meaning thorough regular brushing and flossing, wearing elastics, etc.) is often less of an issue with adults than with teens. Plus, there are some options that can help ensure your orthodontic appliances will fit in with a more mature image.

One is colorless braces. In this system, the brackets (the parts that are bonded to the front teeth and hold the archwire) are made of a clear ceramic material that blends in with the tooth's natural color. This makes them hard to see unless you look closely. Inconspicuous yet effective, clear braces have been the first choice of many celebrities, such as Tom Cruise and Faith Hill... and lots of “regular” adults too.

Another option is lingual braces. These are truly invisible, because they attach behind the teeth (on the tongue side) instead of in front. They work just like the standard braces, and they're appropriate in many situations. However their cost is higher, and the space they occupy in the mouth may take the wearer a bit of time to get used to.

A third option is clear aligners. Unlike braces, which aren't normally removed until orthodontic treatment is nearly complete, clear aligners are easily removable. They consist of a series of transparent trays made of special plastic, which are worn over the teeth 22 hours per day. Each tray in the series is worn for a few weeks, and each moves the teeth a small amount; all together, they can accomplish a big change.

Aligners work well for correcting mild to moderate malocclusion (bite problems). Plus, you can temporarily remove them for important social occasions. But best of all, they're virtually undetectable — so whether or not you play the role of a wizard in the movies, you won't need a magic spell to make them invisible!

Which option is right for you? That's something we would be happy to discuss.
