For one out of three Americans, a bite of ice cream or a sip of hot coffee can set off a sudden jolt of pain. Fortunately, there are ways to reduce these painful episodes of tooth sensitivity and their severity.
To understand the primary reasons that people experience tooth sensitivity, we must first consider a little tooth anatomy. Just below a tooth's outer enamel is a layer of tooth structure called dentin, composed of tiny tunnels or tubules that transmit sensations of temperature or pressure to the nerves in the central pulp. These tubules are analogous to conduits through which electrical wires pass.
Enamel on the crown, along with gum tissue and a thin material called cementum covering the roots, help muffle sensations so as to prevent an overload on the nerves. But if either of those protective areas become compromised the nerves could in turn experience the full brunt of these sensations.
As such, softened and eroded enamel from tooth decay could expose the dentin. Receding gums, commonly caused by gum disease, can also expose dentin near the roots since the remaining cementum offers little protection. In either case, nerves in the pulp may become subject to extreme sensations caused by temperature or while biting down, which then causes them to fire off pain signals to the brain.
Thus, to treat sensitive teeth we must first determine whether it's the result of tooth decay, gum disease or some other condition, and then treat any underlying disease. If it's decay-related, we'll want to repair any cavities with a filling, or perform a root canal if the infection has spread deeper into the tooth.
For receded gums, we'll first want to treat any lingering gum disease. Once we've brought the infection under control, it's possible then for the gums to heal and regenerate, eventually treating the roots with desensitizing products. In some cases, though, we may have to surgically graft new tissue to the receded area to cover the roots.
The good news is that you can lower your chances of tooth sensitivity by preventing these dental diseases. To do that, be sure you're brushing and flossing daily to remove disease-causing plaque, and visiting your dentist at least twice a year for professional cleanings and checkups.

If you wince in pain while eating or drinking something hot or cold, you’re not alone: tooth sensitivity afflicts one in three Americans. To understand what’s possibly going on, let’s look first at tooth anatomy.
Teeth are mainly composed of three layers: an outer protective enamel that covers the upper crown, a middle layer called dentin and an inner pulp. The dentin is composed of small tubules that transmit outer temperature and pressure sensations to nerves in the pulp.
The enamel serves as a “muffler,” damping sensations to protect the nerves from overload. In the root area, the gums and a thin material called cementum covering the roots also help muffle sensation.
But sometimes teeth can lose this muffling effect and the nerves encounter the full brunt of the sensations. The most common reason is gum recession, usually caused by periodontal (gum) disease. The gums have shrunk back or “receded,” and after a short while the cementum covering will also be lost, exposing the dentin in the root area.
Another problem is enamel erosion caused by mouth acid. Chronic high acidity, often caused by bacterial growth or acidic foods and beverages, can dissolve the enamel’s mineral content, causing decay and exposure as well of the underlying dentin.
To avoid future tooth sensitivity, it pays to prevent these two dental problems. The most important thing you can do is practice daily brushing and flossing to reduce bacterial plaque and see your dentist regularly for dental cleanings and checkups.
But if you’re already experiencing symptoms, you’ll first need an accurate diagnosis of the cause. If it’s related to gum disease, immediate treatment could help stop or even reverse any gum recession. To address enamel erosion, your dentist may be able to protect and strengthen your teeth with sealants and topical fluoride.
There are also things you and your dentist can do to reduce your symptoms. One is for you to use hygiene products with fluoride, which can take the edge off of sensitivity, or potassium, which helps reduce nerve activity. Your dentist can further reduce nerve sensitivity by blocking the tubules with sealants and bonding agents.
Tooth sensitivity is an irritating problem in itself; more importantly, though, it’s often a warning of something else seriously wrong that needs attention. If you’re feeling a little sensitive in the teeth, see your dentist as soon as possible.
