Your teeth suddenly hurt when you breathe in cold air or drink something cold. It is sharp and alarming. Cold sensitivity has several distinct causes — and knowing which one you have determines the right treatment.
Worn Enamel Is Often the Culprit
Your tooth enamel is the hard protective layer on the outside of your teeth. Over time it can wear thin from brushing too hard, grinding, or simply from age. When enamel wears away, the sensitive inner part of your tooth becomes exposed to temperature changes. That is what sends that sharp pain shooting through your mouth.
Gum Recession Exposes Sensitive Roots
Your gums naturally recede as you get older, but aggressive brushing and gum disease can speed this up. Unlike enamel, your tooth roots have no protective coating. Cold reaches the nerves inside your teeth directly through the exposed roots. This causes pain that can be more intense than enamel-related sensitivity.
Cavities and Cracks Let Cold In
A cavity or cracked tooth creates another pathway for cold to reach your nerve. This type of sensitivity often sticks around longer after you stop drinking something cold. If you notice pain in one specific tooth that does not go away, that is worth getting checked.
Recent Dental Work Temporarily Increases Sensitivity
After a filling, crown, or teeth whitening, you might notice more cold sensitivity. This usually settles down within a few weeks as your tooth settles. Talk to your dentist if it persists or gets worse.
What You Can Do About It
Use a toothpaste designed for sensitive teeth. Switch to a soft-bristled brush and ease up on your brushing pressure. Avoid acidic foods and drinks which erode enamel. But do not guess about the cause — your dentist can pinpoint exactly why your teeth hurt and recommend the right treatment.
