You may be among the one in three Americans who suffer from the pain of tooth sensitivity. Before attempting treatment, though, we must first identify the cause.
Your teeth are made of layers of different organic tissue. The pulp at the center of the tooth contains nerves that transmit pain or pressure sensation to the brain. The pulp is encased by dentin, a layer of tissue composed of tiny tubules that conduct temperature and pressure changes from outside the tooth to the pulp nerves. The hard outer enamel shell shields the dentin from over-stimulation from these sensations.
There are, however, some instances where the dentin may become exposed and cause sensitivity in the tooth. This can occur when the gum tissue recedes and the root of the tooth is exposed to the oral environment. If the root loses its surface coating (referred to as cementum, a cement-like outer layer around the root surfaces) because of over-aggressive brushing (too hard for too long) or advanced periodontal (gum) disease, sensitivity is often the result.
Another instance is enamel erosion. Although made of the hardest substance in the human body, enamel has one major enemy — acid. A high oral acid level brought on by over-consuming acidic foods and beverages or as a symptom of gastric reflux disease dissolves (de-mineralizes) the enamel’s mineral content. Brushing just after eating actually contributes to de-mineralization because the enamel is in a softer state. It requires forty-five minutes to an hour for your saliva to neutralize acid and restore minerals to the enamel — you may actually be brushing away enamel with this practice.
Once we know the underlying cause, we can use an appropriate method to reduce sensitivity. One way is to reduce nerve sensitivity in the dentin’s tubules or block them altogether. There are several chemical products for both home and dental office application that can reduce sensitivity and encourage enamel re-mineralization (as can the fluoride added to toothpaste). We can also strengthen enamel and provide a mechanical barrier to acid through concentrated fluoride in a varnish applied to tooth and root surfaces. And, life-like restorations like crowns or veneers not only improve the appearance of your teeth, they can also provide coverage for exposed dentin.

Nothing ruins a thirst-quenching cold beverage or a dish of your favorite ice cream like a sudden pang of tooth sensitivity. If you're experiencing this problem — and especially if there are other triggers, like biting down — we encourage you to make an appointment. It could be something harmless and temporary, but it's always prudent to check. At the very least, you'll feel better once the underlying problem is identified and treated if necessary.
Here are some common sources of tooth sensitivity:
- Enamel erosion — typically caused by acidic beverages/food, regurgitation of stomach acids (due to gastroesophageal reflux disease [GERD] or the eating disorder bulimia), or improper brushing
- Tooth decay — a sugary diet and poor dental hygiene may be contributing factors
- Tooth fracture or chipping due to tooth grinding (bruxism) or other trauma
- Gum recession due to age, improper tooth brushing, or gum disease
- Filling that needs repair or replacement
- Residual effects of recent dental work
Some things you can try at home to minimize sensitivity include:
- Ease up on the toothbrush; a light touch is all that's needed to dislodge daily plaque build-up
- Try using fluoride-containing toothpaste like an ointment over the affected area (fluoride decreases fluid exchange from the oral environment to the nerve inside the tooth)
- Take a non-steroidal anti-inflammatory such as ibuprofen (use judiciously and according to the package insert guidelines)
Discomfort related to recent dental work should resolve on its own; give it several weeks. If you're feeling discomfort for another reason, even if the sensitivity subsides, the underlying cause may still require attention.

Tooth sensitivity is an issue that can range from a slight twinge at times to downright excruciating pain. However, before we continue, understanding the cause of tooth sensitivity is helpful to both relieving and treating it.
Tooth enamel is inert in that it has no nerve supply and thus it protects the teeth from temperature and pressure changes — the main cause of sensitivity. Once it is compromised, worn thin, or exposed due to gum recession, it leaves the delicate nerve fibers within the dentin vulnerable to touch, acid, and temperature change. These nerve fibers most often grab your attention when they come in contact with heat, cold, or a “double whammy” combination of both cold and sweet. They also become sensitive to touch — even the bristles of a soft toothbrush can irritate exposed dentin.
As for the causes of tooth sensitivity, one common cause we see is aggressive brushing. Yes, too much brushing can be bad for you! To be more specific, excessive, improper brushing with a sawing back and forth motion can erode the gum tissues, expose, wear, and even groove the dentin. Another cause for sensitivity can be from the destructive process of tooth decay that eats through the enamel and into the dentin.
