EdenSherandtheLostRetainer

Fans of the primetime TV show The Middle were delighted to see that high school senior Sue, played by Eden Sher, finally got her braces off at the start of Season 6. But since this popular sitcom wouldn’t be complete without some slapstick comedy, this happy event is not without its trials and tribulations: The episode ends with Sue’s whole family diving into a dumpster in search of the teen’s lost retainer. Sue finds it in the garbage and immediately pops it in her mouth. But wait — it doesn’t fit, it’s not even hers!

If you think this scenario is far-fetched, guess again. OK, maybe the part about Sue not washing the retainer upon reclaiming it was just a gag (literally and figuratively), but lost retainers are all too common. Unfortunately, they’re also expensive to replace — so they need to be handled with care. What’s the best way to do that? Retainers should be brushed daily with a soft toothbrush and liquid soap (dish soap works well), and then placed immediately back in your mouth or into the case that came with the retainer. When you are eating a meal at a restaurant, do not wrap your retainer in a napkin and leave it on the table — this is a great way to lose it! Instead, take the case with you, and keep the retainer in it while you’re eating. When you get home, brush your teeth and then put the retainer back in your mouth.

If you do lose your retainer though, let us know right away. Retention is the last step of your orthodontic treatment, and it’s extremely important. You’ve worked hard to get a beautiful smile, and no one wants to see that effort wasted. Yet if you neglect to wear your retainer as instructed, your teeth are likely to shift out of position. Why does this happen?

As you’ve seen firsthand, teeth aren’t rigidly fixed in the jaw — they can be moved in response to light and continuous force. That’s what orthodontic appliances do: apply the right amount of force in a carefully controlled manner. But there are other forces at work on your teeth that can move them in less predictable ways. For example, normal biting and chewing can, over time, cause your teeth to shift position. To get teeth to stay where they’ve been moved orthodontically, new bone needs to form around them and anchor them where they are. That will happen over time, but only if they are held in place with a retainer. That’s why it is so important to wear yours as directed — and notify us immediately if it gets lost.

And if ever you do have to dig your retainer out of a dumpster… be sure to wash it before putting in in your mouth!

DontPutOffGettingTreatmentforYourSensitiveTeeth

While out with friends one evening, you take a bite of ice cream. Suddenly, pain shoots through your teeth. It only lasts a second, but it's enough to ruin your good time.

This could be tooth sensitivity, a painful reaction to hot or cold foods. It often occurs when the enamel in prolonged contact with acid has eroded. Acid is a waste product of bacteria found in plaque, a thin film of food particles that builds up on tooth surfaces due to inadequate brushing and flossing. Enamel normally mutes temperature or pressure sensation to the underlying dentin layer and nerves. Loss of enamel exposes the dentin and nerves to the full brunt of these sensations.

Sensitivity can also happen if your gums have shrunk back (receded) and exposed dentin below the enamel. Although over-aggressive brushing can often cause it, gum recession also happens because of periodontal (gum) disease, a bacterial infection also arising from plaque.

The best way to avoid tooth sensitivity is to prevent enamel erosion or gum recession in the first place. Removing accumulated plaque through daily brushing and flossing is perhaps the most essential part of prevention, along with a nutritious diet low in sugar and regular dental cleanings and checkups.

It's also important to treat any dental disease that does occur despite your best hygiene efforts. Gum disease requires aggressive plaque removal, especially around the roots. While receded gum tissues often rebound after treatment, you may need gum grafting surgery to restore lost tissues if the gums have receded more deeply. For enamel erosion and any resulting decay you may need a filling, root canal treatment or a crown, depending on the depth and volume of structural damage.

While you're being treated you can also gain some relief from ongoing sensitivity by using a toothpaste with potassium nitrate or similar products designed to desensitize the dentin. Fluoride, a known enamel strengthener, has also been shown to reduce sensitivity. We can apply topical fluoride directly to tooth surfaces in the form of gels or varnishes.

Don't suffer through bouts of tooth sensitivity any more than you must. Visit us for a full exam and begin treatment to relieve you of the pain and stress.
