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.

BrushorFlossFirstHeresWhatYouNeedtoKnowtoDecide

If you like conundrums like "Which came first? The chicken or the egg?", then you may enjoy this one: "Which should you do first, brush or floss?"

Both of these oral hygiene tasks are equally important for removing dental plaque, a thin bacterial film that forms on teeth after eating. Removing plaque on a daily basis minimizes your risk for developing tooth decay or periodontal (gum) disease, the top causes for tooth loss. Brushing removes plaque from broad tooth surfaces, while flossing removes it from between teeth where brushing can't reach.

There is wide consensus that you need both brushing and flossing to thoroughly remove plaque. But there is a debate over which of these two tasks you should do first for the most effective outcome. Those debates are more or less good-natured, but there are proponents on both sides on which task should come first.

Those on the "Brush First" side say brushing initially gets the bulk of accumulated plaque out of the way. If you floss first, you may be plowing through a lot of soft plaque, which can quickly turn your floss into a gunky mess. More importantly, you may only be moving plaque around with the floss, not actually removing it. By brushing first, there's less plaque to deal with when flossing.

"Floss First" folks, though, say flossing before you brush loosens plaque stuck between teeth that can be more easily brushed away. But perhaps a more important reason is psychological: People don't really like flossing as much as brushing. Because of this, putting it off to the end may mean it doesn't happen; doing it first will help ensure it actually gets done.

In the end, though, the order you perform these tasks comes down to personal preference. You can try both ways to see which one suits you best. The important thing, however, is that you do both tasks—if you do, you can greatly lower your risk of dental disease that could rob you of your teeth.

StayAheadofDecay-SpreadingRootCavities

Finding out you have a cavity isn't the best of news. But finding out it's a root cavity is even worse: if not treated, the decay can spread more rapidly than a cavity occurring in the tooth's crown surfaces.

Our teeth are basically composed of two parts: the crown, the visible tooth above the gum line, and the roots, the hidden portion beneath the gums. The root in turn fits into a bony socket within the jaw to help hold the tooth in place (along with attached gum ligaments).

A tooth crown is covered by an ultra-hard layer of enamel, which ordinarily protects it from harmful bacteria. But when acid produced by bacteria comes into prolonged contact with enamel, it can soften and erode its mineral content and lead to a cavity.

In contrast to enamel, the roots have a thin layer of material called cementum. Although it offers some protection, it's not at the same performance level as enamel. But roots are also normally covered by the gums, which rounds out their protection.

But what happens when the gums shrink back or recede? This often occurs with gum disease and is more prevalent in older people (and why root cavities are also more common among seniors). The exposed area of the roots with only cementum standing in the way of bacteria and acid becomes more susceptible to cavity formation.

Root cavities can be treated in much the same way as those that occur in the crown. We first remove any decayed tooth structure with a drill and then place a filling. But there's also a scenario in which the cavity is below the gum line: In that case, we may need to gain access to the cavity surgically through the gums.

If you have exposed root areas, we can also treat these with fluoride to strengthen the area against cavity formation. And, as always, prevention is the best treatment: maintain a daily schedule of brushing and flossing and regular dental cleanings to remove bacterial plaque.

Because decay can spread within a tooth, dealing with a root cavity should be done as promptly as possible. But if we diagnose and initiate treatment early, your chances of a good outcome are high.
