A scoop of ice cream is one of life's little pleasures. But for one in three Americans, it could be something altogether different—an excruciating pain when cold ice cream meets teeth. This short but painful experience that can happen when dental nerves encounter hot or cold temperatures is called tooth sensitivity.
A look at tooth anatomy will help explain why. Teeth are mainly composed of outer enamel, a layer of nerves and blood vessels within the tooth called the pulp, and dentin, a porous layer in between. The pulp nerves pick up temperature and pressure sensations from outside the teeth through a network of tiny passageways (tubules) in the dentin. Enamel muffles these sensations before traveling the tubules, which prevents overstimulation of the nerves.
This careful balance can be disrupted, however, if the enamel becomes eroded by acid from foods or beverages, or as a byproduct of bacteria. This exposes the underlying dentin to the full brunt of outward sensations, which can then impact the nerves and cause them to overreact.
This hyper-sensitivity can also occur around the tooth roots, but for a different reason. Because the gums primarily protect this area rather than enamel, the roots can become hyper-sensitive if they lose gum coverage, a condition known as gum recession caused mainly by gum disease or over-aggressive hygiene.
Besides using dental products that block nerve sensation, reducing sensitivity largely depends on addressing the underlying cause. If gum disease, the focus is on removing plaque, a bacterial film on dental surfaces that causes and sustains the disease. Stopping an infection allows the gums to heal and hopefully regain their original teeth coverage. More advanced cases, though, may require grafting surgery to foster gum regeneration.
If the cause is enamel erosion or other results of decay or trauma, we can utilize a number of treatments depending on the extent of tooth damage including cavity filling, root canal therapy or crowning. As a last resort, we may need to remove a tooth that's beyond reasonable repair.
If you've begun to experience sensitive teeth, it's important that you see us as soon as possible. The earlier we can diagnose the cause, the less invasive we can be with treatments to ease or even stop this most unpleasant experience.

You're more apt to lose teeth because of periodontal (gum) disease and tooth decay than any other cause. But neither of these bacterial diseases have to happen: You can prevent them through daily brushing and flossing and twice-a-year dental cleanings.
But that's not all: You can also boost your dental care practices by eating foods that strengthen and protect teeth. On the other hand, a poor diet could reduce the effectiveness of your oral hygiene practices in preventing tooth decay or gum disease.
A diet that might lead to the latter is often high in refined sugar (sucrose), often added to processed foods and snacks to improve taste. But sucrose is also a top food source for oral bacteria, increasing their numbers when it's readily available. A higher bacterial population greatly increases your risk for tooth decay or gum disease.
On the other hand, certain foods benefit your overall dental health. Fresh fruits and vegetables, for example, are filled with nutrients and minerals like vitamin D or calcium that strengthen teeth against disease. And although they can also contain natural sugars, these don't pose the same problems as added sucrose due to the plant fiber you consume with them.
Dairy foods can also help you maintain healthy teeth and gums. Milk and cheese contain minerals like calcium and phosphorus, and a protein called casein, all of which strengthen teeth against decay. The enzymes in cheese stimulate saliva, which in turn neutralizes mouth acid and prevent it from harming enamel.
Some foods are also natural sources of fluoride, a mineral that strengthens tooth enamel. One example is black tea, which also, along with green tea, contains antioxidants that protect against cancer.
The best strategy for “tooth-friendly” nutrition is to pursue a diet that's high in fiber-rich natural foods and low in sugar-added processed foods. In practice, you'll want most of your diet to consist of fresh fruits and vegetables and low-fat dairy food, while minimizing foods with added sugar.
Following this kind of diet will certainly benefit your overall health. But it will also make it easier for you to prevent dental disease and keep your teeth and gums healthy.

Tara Lipinski loves to smile. And for good reason: The Olympic-gold medalist has enjoyed a spectacular career in ladies' figure skating. Besides also winning gold in the U.S. Nationals and the Grand Prix Final, in 1997 Lipinski became the youngest skater ever to win a World Figure Skating title. Now a sports commentator and television producer, Lipinski still loves to show her smile—and counts it as one of her most important assets. She also knows the importance of protecting her smile with daily hygiene habits and regular dental care.
Our teeth endure a lot over our lifetime. Tough as they are, though, they're still vulnerable to disease, trauma and the effects of aging. To protect them, it's essential that we brush and floss every day to remove bacterial plaque—that thin accumulating film on teeth most responsible for tooth decay and gum disease.
To keep her smile in top shape and reduce her chances of dental disease, Lipinski flosses and brushes daily, the latter at least twice a day. She also uses a tongue scraper, a small handheld device about the size of a toothbrush, to remove odor-causing bacteria and debris from the tongue.
Lipinski is also diligent about visiting the dentist for professional cleanings and checkups at least twice a year because even a dedicated brusher and flosser like her can still miss dental plaque that can then harden into tartar. Dental hygienists have the training and tools to clear away any lingering plaque and tartar that could increase your disease risk. It's also a good time for the dentist to check your teeth and gums for any developing problems.
The high pressure world of competitive figure skating and now her media career may also have contributed to another threat to Lipinski's smile: a teeth-grinding habit. Teeth grinding is the unconscious action—often while asleep—of clenching the jaws together and producing abnormally high biting forces. Often a result of chronic stress, teeth grinding can accelerate tooth wear and damage the gum ligaments attached to teeth. To help minimize these effects, Lipinski's dentist created a custom mouthguard to wear at night. The slick plastic surface of the guard prevents the teeth from generating any damaging biting forces when they clench together.
The importance of an attractive smile isn't unique to celebrities and media stars like Tara Lipinski. A great smile breeds confidence for anyone—and it can enhance your career, family and social relationships. Protect this invaluable asset with daily oral hygiene, regular dental visits and prompt treatment for disease or trauma.
Enamel is the hardest substance in the human body, and for good reason—it's your teeth's first line of defense against wearing and harmful oral bacteria. But although enamel can “take a licking and keep on ticking,” it can lose its mineral content, soften and eventually erode to expose the teeth to bacteria.
Here are 4 tips for protecting your enamel so it keeps on protecting you.
Practice sound brushing techniques. Brushing is necessary for removing bacterial plaque that can trigger dental disease. But how you brush could prove not only ineffective, but also harmful to your enamel. So, be sure you're brushing all tooth surfaces, but not too forcefully or too often (twice a day is enough)—otherwise, you could wear down enamel and damage your gums.
Wait to brush after eating. The acid levels in the mouth go up during eating, causing an immediate softening of enamel. But saliva then goes to work neutralizing acid and helping to restore enamel's mineral content. Since it takes saliva about thirty minutes to an hour to complete this task, wait on brushing at least that long. Otherwise, you might remove tiny traces of temporarily softened enamel.
Avoid eating right before bed. While we sleep, our saliva flow decreases until we wake up. If you eat just before bed, you may not be giving your saliva enough time to neutralize acid before it “goes to sleep” with you for the night. So, give your saliva ample time to neutralize any remaining acid by not eating anymore at least an hour before you turn in.
Limit drinking acidic beverages. Some of our favorite drinks—sodas, energy and sports drinks, and even some juices—can be high in acid. To protect your enamel, reduce your consumption of these types of beverages in favor of water or milk (the calcium in the latter will also benefit your enamel). When you do drink acidic beverages, use a straw to minimize contact of the fluid with your enamel.
Healthy and strong enamel is the key to healthy and strong teeth. It's worth taking these steps to protect this important defense against destructive tooth decay.

Chronic joint pain (temporomandibular joint disorder or TMD) in and of itself can make life miserable. But TMD may not be the only debilitating condition you're contending with—it's quite common for TMD patients to also suffer from fibromyalgia.
Fibromyalgia is a condition with a variety of muscular and neurological symptoms like widespread pain, joint stiffness, headaches and tingling sensations. These symptoms can also give rise to sleep and mood disorder, as well as difficulties with memory. Fibromyalgia can occur in both males and females, but like TMD, it's predominant among women, particularly those in their child-bearing years.
In the past, physicians were mystified by these symptoms of body-wide pain that didn't seem to have an apparent cause such as localized nerve damage. But continuing research has produced a workable theory—that fibromyalgia is related to some defect within the brain or spinal cord (the central nervous system), perhaps even on the genetic level.
This has also led researchers to consider that a simultaneous occurrence of TMD and fibromyalgia may not be coincidental—that the same defect causing fibromyalgia may also be responsible for TMD. If this is true, then the development of new treatments based on this understanding could benefit both conditions.
For example, it's been suggested that drugs which relieve neurotransmitter imbalances in the brain may be effective in relieving fibromyalgia pain. If so, they might also have a similar effect on TMD symptoms.
As the study of conditions like fibromyalgia and TMD continues, researchers are hopeful new therapies will arise that benefit treatment for both. In the meantime, there are effective ways to cope with the symptoms of TMD, among them cold and hot therapy for inflamed jaw joints, physical exercises and stress reduction techniques.
The key is to experiment with these and other proven therapies to find the right combination for an individual patient to find noticeable relief. And perhaps one day in the not too distant future, even better treatments may arise.
