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.

It's a common practice among people slowly losing their teeth to have their remaining teeth removed. They find dentures to be less costly than replacing one tooth at a time or caring for those that remain. On the other hand, it's usually healthier for the mouth to preserve remaining teeth as long as possible, replacing them only as necessary.
This latter strategy has up to now been difficult and expensive to achieve. But dental implants are changing that—using these imbedded titanium metal devices with a variety of restorations, we're able to better plan and implement staged tooth replacement.
Most people associate implants with single tooth replacements of a life-like crown cemented or screwed into an abutment attached to the implant post. This can play an early role in a staged replacement plan, but at some point, multiple single-tooth implants can become quite expensive.
Implants, however, have a much broader range of use. A few strategically placed implants can support a variety of restorations, including bridges and removable or fixed dentures. Four to eight implants, for example, can secure a fixed denture replacing all teeth on a jaw, far fewer than the number needed to replace the teeth individually.
Implants may also improve the function of traditional restorations. For instance, dentures can't stop the bone loss that often results from tooth loss—in fact, they will accelerate it as they rub and irritate the bony ridges of the jaw. By contrast, implants stimulate bone growth, slowing or even stopping the process of bone loss.
In a traditional bridge, the outer crowns of the restoration are bonded to the teeth on either side of the missing tooth gap (the middle crowns fill the gap). These support teeth must be permanently altered to accommodate the crowns. But an implant-supported bridge doesn't depend on other teeth for support, thus eliminating the need to permanently alter any teeth.
More importantly, previously placed implants often become part of the next stages of tooth replacement, like building on an addition onto an existing house. All in all, including implants in your ongoing dental restoration can help you enjoy the benefits of preserving your natural teeth for much longer.
