You’re biting down on a cold dessert or possibly sipping a hot beverage, and then, “Ouch!” The pain strikes, suddenly and without warning, and the enjoyable, comforting feeling you were experiencing with your delicious food or beverage is momentarily shattered. Tooth sensitivity and pain is common among adults, and it is especially common among certain patients who do not or have not followed a strict oral hygiene regimen that includes regular dental checkups and professional cleanings. What causes tooth sensitivity, what can you do to alleviate it, and when is it a warning that something more serious may be wrong with your teeth and gums?

What Causes Tooth Sensitivity?

Tooth sensitivity and pain is usually caused by nerve irritation, more specifically the nerves contained in the tooth dentin. The dentin and inner pulp of the tooth become exposed when the enamel of the tooth wears down or the gums recede at the base of the tooth, and fluid can then move through a cluster of tiny tubes located in the dentin, as the tops of these tubes are exposed. When dentin is exposed in this matter, contact from hot or cold liquids or foods, physical touch, and even cold air can cause nerve pain and irritation.

Is Tooth Sensitivity Harmful?

Tooth irritation and pain are common, in fact it’s the most common dental ailments affecting adults. Simply experiencing brief and mild bouts of irritation and pain are not enough to warrant a trip to the dentist, although it is important to note if the frequency or the intensity of the pain increase. If your tooth remains sensitive for more than a week, or if you experience acute pain from cold air or liquids, you should set up an immediate appointment for a professional evaluation. Your dentist may recommend professionally applying a sealant or another material to cover the dentin, or may recommend a special desensitizing toothpaste. Finally, your dentist may also recommend changes to your diet or a reduction in the number of soft drinks or cups of coffee consumed throughout the day.
