If you wince while eating certain foods and beverages, you're not alone — one in three Americans suffer from the pain of tooth sensitivity. Fortunately, there are ways to treat it and reduce the pain.
Dentinal hypersensitivity occurs when dentin loses its protective cover. Dentin, a living tissue within a tooth, is composed of tiny tubules that act as conduits for transmitting sensations from the surface of the tooth to the nerves in the inner pulp. These tubules are protected by cementum, a hard, outer layer that covers the tooth root. But when the root becomes exposed, the cementum is easily stripped from the root. The tubules become more sensitive to sensations of temperature or pressure.
Receding gums are the main culprit for root exposure. This condition can result from periodontal disease, which arises mainly from poor oral hygiene. At the other end of the spectrum, over-aggressive brushing can lead to receding gums. Brushing may also contribute to another source of dentinal hypersensitivity: enamel erosion. The minerals in enamel begin to soften and erode as the acidic level of the mouth rises. Saliva neutralizes the acid and can restore a neutral balance in about thirty minutes to an hour after eating. If you brush before this process completes, you could brush away some of the softened enamel.
To properly treat tooth sensitivity, our first step is to find the cause. If it stems from improper or premature brushing, we can counsel you on proper technique. If periodontal disease is a factor, we would first treat the disease and then work with you on a proper oral hygiene regimen to reduce bacterial plaque, the main cause of the infection.
There are treatments as well to reduce nerve sensitivity and thereby ease the pain. Toothpastes and other mouth products with fluoride help reduce sensitivity, as well as products containing potassium nitrate or potassium citrate. We can also apply a varnish containing a concentrated dose of fluoride directly to tooth surfaces. Another approach is to block the tubules using bonding agents or sealants; this will reduce their capacity to receive and transmit sensations.

Her parents Will and Jada are Hollywood royalty, who helped her land her first acting role when she was 7. She released a hit single, “Whip My Hair,” before she had quite reached the age of 10; shortly afterward, she was signed to a record label. Yet the young singer and actress Willow Smith has at least one thing in common with plenty of ‘tweens and teens across America: She needed to wear braces to correct problems with the alignment of her teeth.
Why do braces seem to be a part of growing up for so many kids? One answer is because they work so well. Braces apply gentle pressure to the teeth through a thin, flexible wire called an archwire. Attached to the teeth with a metal or ceramic bracket, the archwire exerts a light force which causes teeth to gradually move into better positions. Sometimes, when additional force is needed, elastic bands or other appliances may be used in conjunction with braces.
Most everyone is familiar with the silvery metal “tracks” of traditional braces. But did you know that there are a number of other options too? For a more inconspicuous look, you may be able to have braces with tooth-colored ceramic brackets; then, only the thin archwire will be visible in your mouth. It’s even possible in some cases to place the metal wires and brackets on the tongue side of the teeth. With this system, called lingual braces, the orthodontic hardware is truly invisible.
What if you didn’t need metal braces at all? Some people can get good results using a system of clear plastic aligners instead of braces. The aligners are worn 23 hours a day, but can be taken off for cleaning and for important events. They work best for correcting mild or moderate alignment problems.
Still, plenty of people feel that if they’re going to wear braces, they might as well flaunt them. That’s why some types of braces are available with bands that come in different colors. When Willow’s brother Jayden wore braces, he was reported to favor red and black ones. Jayden, who is about two years older than his sister, had his braces removed just before Willow got hers put on.
So if it turns out that you need braces, remember that lots of your favorite celebrities wore them too. And keep in mind that, depending on your own situation, you may have several options to choose from.
