Have you ever taken a sip of hot coffee or a bite of ice cream and felt a sudden sharp pain in your tooth? If so, you’re not alone. For today’s Dental Minute, we’re talking about tooth sensitivity, what causes it, what it means, and what you can do about it.

To understand sensitivity, it helps to know a little about your teeth. Beneath the hard outer layer, called enamel, is a softer layer called dentin. Dentin contains thousands of tiny tubules that lead directly to the nerve inside your tooth. When dentin becomes exposed, hot, cold, sweet, acidic, or even cold air can trigger that sharp, uncomfortable sensation.

So how does dentin become exposed? There are actually several possible causes. Brushing too aggressively can wear down enamel and gums. Gum recession can expose the roots of your teeth. Teeth grinding, acidic foods and drinks, cavities, cracked teeth, worn fillings, and even some whitening products can contribute to sensitivity.

One thing many people don’t realize is that tooth sensitivity isn’t always something you should just ‘live with.’ Sometimes it’s a sign that something else is going on, like tooth decay, gum disease, or a cracked tooth that needs attention.

The good news? There are solutions. Depending on the cause, treatment might include sensitivity toothpaste, fluoride treatments, bonding, a nightguard for grinding, or addressing underlying dental problems before they become more serious.

If your teeth are sending you little warning signals every time you eat or drink, don’t ignore them. Sensitivity is your smile’s way of telling you something may need attention. Let us help you find the cause and get you back to enjoying your favorite foods without the sting.
