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.

Many recent high school graduates will soon begin their first year in college, and for many it will be their first time living away from home. But with the excitement of new freedom, there’s also the opportunity to make poor choices that could impact long-term health, especially teeth and gums.
Here, then, are 5 tips for keeping your teeth and gums healthy during the college years.
Watch what you eat and drink. At any stage of life, a nutritious, balanced diet low in sugar and high in fiber is vital to a healthy mouth. Snack moderately on fresh fruit, nuts or dairy foods, not sugary, processed products. Be sure also to drink plenty of water for hydration, not sodas or sports drinks whose high acid content can soften enamel and open the door to tooth decay.
Don’t abuse alcohol or use tobacco. Consuming too much alcohol can do more than leave you momentarily impaired — it can cause dry mouth, which contributes to tooth decay and increases your risk of oral cancer. Any form of tobacco can raise your risk for disease, especially oral cancer; high levels of nicotine may also inhibit your gum’s ability to fight infection, which increases your risk of periodontal (gum) disease.
Avoid oral piercings. Those tiny pieces of hardware attached to lips, tongue, gums or even through teeth may be all the rage, but they’re a recipe for immediate and future mouth problems. Oral piercings can lead to chipped teeth, gum recession and a higher chance of dental disease.
Practice safe sex. Certain sexual behaviors can raise your risk of contracting human papilloma virus (HPV16) that in turn increases your risk of oral cancer. You can also develop genital herpes in the mouth, which although manageable won’t go away.
Keep up your oral hygiene care. Taking care of your teeth and gums is a permanent, daily concern. Whatever your college schedule, be sure you’re brushing once or twice a day and flossing once. And don’t forget to visit us at least twice a year for a thorough cleaning (to get plaque you can’t reach with daily hygiene) and a checkup to keep dental disease under control.
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.
