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.

If we could go back in time, we all probably have a few things we wish we could change. Recently, Dr. Travis Stork, emergency room physician and host of the syndicated TV show The Doctors, shared one of his do-over dreams with Dear Doctor magazine: “If I [could have] gone back and told myself as a teenager what to do, I would have worn a mouthguard, not only to protect my teeth but also to help potentially reduce risk of concussion.”
What prompted this wish? The fact that as a teenage basketball player, Stork received an elbow to the mouth that caused his two front teeth to be knocked out of place. The teeth were put back in position, but they soon became darker and began to hurt. Eventually, both were successfully restored with dental crowns. Still, it was a painful (and costly) injury — and one that could have been avoided.
You might not realize it, but when it comes to dental injuries, basketball ranks among the riskier sports. Yet it’s far from the only one. In fact, according to the American Dental Association (ADA), there are some two dozen others — including baseball, hockey, surfing and bicycling — that carry a heightened risk of dental injury. Whenever you’re playing those sports, the ADA recommends you wear a high-quality mouth guard.
Mouthguards have come a long way since they were introduced as protective equipment for boxers in the early 1900’s. Today, three different types are widely available: stock “off-the-shelf” types that come in just a few sizes; mouth-formed “boil-and-bite” types that you adapt to the general contours of your mouth; and custom-made high-quality mouthguards that are made just for you at the dental office.
Of all three types, the dentist-made mouthguards are consistently found to be the most comfortable and best-fitting, and the ones that offer your teeth the greatest protection. What’s more, recent studies suggest that custom-fabricated mouthguards can provide an additional defense against concussion — in fact, they are twice as effective as the other types. That’s why you’ll see more and more professional athletes (and plenty of amateurs as well) sporting custom-made mouthguards at games and practices.
“I would have saved myself a lot of dental heartache if I had worn a mouthguard,” noted Dr. Stork. So take his advice: Wear a mouthguard whenever you play sports — unless you’d like to meet him (or one of his medical colleagues) in a professional capacity…
Pain has a purpose: it tells us when something's wrong with our bodies. Sometimes it's obvious, like a cut or bruise. Sometimes, though, it takes a bit of sleuthing to find out what's wrong.
That can be the case with a toothache. One possible cause is perhaps the most obvious: something's wrong with the tooth. More specifically, decay has invaded the tooth's inner pulp, which is filled with an intricate network of nerves that react to infection by emitting pain. The pain can feel dull or sharp, constant or intermittent.
But decay isn't the only cause for tooth pain: periodontal (gum) disease can trigger similar reactions. Bacteria living in dental plaque, a thin film of food particles on tooth surfaces, infect the gums. This weakens the tissues and can cause them to shrink back (recede) from the teeth and expose the roots. As a result, the teeth can become painfully sensitive to hot or cold foods or when biting down.
Finding the true pain source determines how we treat it. If decay has invaded the pulp you'll need a root canal treatment to clean out the infection and fill the resulting void with a special filling; this not only saves the tooth, it ends the pain. If the gums are infected, we'll need to aggressively remove all plaque and calculus (hardened plaque deposits) to restore the gums to health.
To further complicate matters, an infection from tooth decay could eventually affect the gums and supporting bone, just as a gum infection could enter the tooth by way of the roots. Once the infection crosses from tooth to gums (or gums to tooth), the tooth's long-term outlook grows dim.
So, if you're noticing any kind of tooth pain, or you have swollen, reddened or bleeding gums, you should call us for an appointment as soon as possible. The sooner we can diagnose the problem and begin appropriate treatment the better your chances of a good outcome — and an end to the pain.
