dentalcare
Wincing at hot coffee or cold air? Learn what commonly causes tooth sensitivity, simple habits that may help, and when it's worth booking a dental exam.
Sensitive teeth are very common, and they don't automatically mean something serious. Here's a calm look at what may be going on.
What does sensitivity feel like?
Most people notice a short, sharp twinge when teeth meet hot, cold, sweet or acidic things, or when breathing in cold air.
Common causes
- Worn enamel
- Gum recession that exposes the root surface
- Brushing too firmly
- Teeth grinding
- A cracked or worn filling
- Cavities
- Recent whitening
Habits that may help
- Use a soft-bristled brush and gentle strokes
- Try a toothpaste made for sensitive teeth
- Limit acidic drinks
- Ask about a nightguard if you grind your teeth
Does sensitivity mean a root canal?
No. Your dentist looks for the cause first and recommends the most conservative option. Many cases are managed without major treatment.
