If you're one of over 30% of Americans who wince in pain when eating and drinking certain foods and beverages, you may have tooth sensitivity. Although there are a number of possible causes, the most common place to look first is tooth dentin.
Lying just under the enamel, dentin consists of tiny tubules that transmit sensations like pressure or temperature variation to the nerves of the inner pulp. The enamel, the gums and a covering on the roots called cementum help dampen these sensations.
But over-aggressive brushing or periodontal (gum) disease can cause the gums to shrink back (recede) and expose the dentin below the gum line; it can also cause cementum to erode from the roots. This exposure amplifies sensations to the nerves. Now when you eat or drink something hot or cold or simply bite down, the nerves inside the dentin receive the full brunt of the sensation and signal pain.
Enamel erosion can also expose dentin, caused by mouth acid in contact with the enamel for prolonged periods. Acid softens the minerals in enamel, which then dissolve (resorb) into the body. Acid is a byproduct of bacteria which live in dental plaque, a thin film of food particles that builds up on teeth due to poor oral hygiene. Mouth acid may also increase from gastric reflux or consuming acidic foods or beverages.
Once we pinpoint the cause of your tooth sensitivity we can begin proper treatment, first and foremost for any disease that's a factor. If you have gum disease, we focus on removing bacterial plaque (the cause for the infection) from all tooth and gum surfaces. This helps stop gum recession, but advanced cases may require grafting surgery to cover the root surfaces.
You may also benefit from other measures to reduce sensitivity:Â applying less pressure when you brush; using hygiene products like toothpastes that block sensations to the dentin tubules or slow nerve action; and receiving additional fluoride to strengthen enamel.
There are effective ways to reduce your tooth sensitivity. Determining which to use in your case will depend on the cause.

Let's say you have a diseased tooth you think might be on its last leg. It might be possible to save it, perhaps with a significant investment of time and money. On the other hand, you could have it replaced with a life-like dental implant.
That seems like a no-brainer, especially since implants are as close as we have to natural teeth. But you might want to take a second look at salvaging your tooth—as wonderful as implants are, they can't beat the real thing.
Our teeth, gums and jaws form an intricate oral system: Each part supports the others for optimum function and health. Rescuing a troubled tooth could be the best way to preserve that function, and replacing it, even with a dental implant, a less satisfying option.
How we save it will depend on what's threatening it, like advanced tooth decay. Caused by bacterial acid that creates a cavity in enamel and underlying dentin, decay can quickly spread into the tooth's pulp and root canals, and eventually threaten the supporting bone.
We may be able to stop decay and save the tooth with a root canal treatment. During this procedure, we remove diseased tissue from the pulp and root canals through a drilled access hole, and then fill the empty spaces. We then seal the access and later crown the tooth to protect it against future infection.
A second common threat is periodontal (gum) disease. Bacteria in dental plaque infect the outer gums and, like tooth decay, the infection quickly spreads deeper into the root and bone. The disease weakens gum attachments to affected teeth, hastening their demise.
To treat gum disease, we manually remove built-up plaque and tartar (hardened plaque). This deprives the infecting bacteria of their primary food source and “starves” the infection. Depending on the disease's advancement, this might take several cleaning sessions and possible gum surgery to access deep pockets of infection around the root.
Because both of these treatment modalities can be quite in-depth, we'll need to assess the survivability of the tooth. The tooth could be too far gone and not worth the effort and expense to save it. If there is a reasonable chance, though, a rescue attempt for your troubled tooth might be the right option.

Gum recession is a serious oral condition in which the gums shrink back or “recede” from their normal position around the teeth. Because they're the primary protection for teeth below the enamel, this can expose the teeth to infection or cause painful sensitivity. And receded gums most certainly can diminish your smile.
But there are preventive measures you can adopt that might help you avoid this unpleasant condition. Here are 4 things you can do to minimize your risk for gum recession.
Practice daily oral hygiene. The main cause for recession is gum disease, a bacterial infection that weakens gum attachment to teeth. Gum disease usually arises from dental plaque, a thin bacterial film that builds up on teeth. Removing it every day with brushing and flossing minimizes the risk of gum disease and gum recession.
But don't overdo it. Although brushing is key to keeping your mouth healthy, too hard and too often can damage your gums and lead to recession. A little “elbow grease” may be appropriate for other cleaning tasks, but not your teeth—use gentle strokes and let the mild abrasives in your toothpaste do the main removal work. And avoid brushing more than twice a day.
See your dentist regularly. Your personal care efforts are a major part of preventing gum recession, but you can greatly increase the effect with professional dental care. That's because with even the best hygiene practice infections and other gum problems can still arise. You may also have inherited thinner gum tissues from your parents that increase your disease risk and bear closer monitoring.
Act quickly at the first signs of disease. Gum disease is a progressive disease, and it doesn't take long for it to become intrenched. The sooner it can be treated, the less likely you'll experience recession. So, make a dental appointment as soon as possible if you notice your gums are swollen, red or painful, or if they bleed easily after brushing.
There are ways to reverse gum recession. But many treatments like grafting surgery to regenerate new gum tissues can be quite involved and expensive. Following these tips can help you avoid gum recession altogether or stop it before it goes that far.
