Sensitive teeth can make eating, drinking and brushing uncomfortable. Some sensitivity is short-lived, but ongoing or worsening sensitivity should be checked by a dentist because it can sometimes be linked to decay, cracks, gum recession or worn enamel.
The right next step depends on what triggers the sensitivity, how long it lasts, and whether there are other symptoms such as pain, swelling, bleeding gums or a broken tooth.
What does tooth sensitivity feel like?
Tooth sensitivity often feels like a sharp, quick pain or zing when teeth are exposed to cold, sweet, hot or acidic foods and drinks. Some people also feel sensitivity when brushing, flossing or breathing in cold air.
If the pain lingers, becomes severe, or happens without an obvious trigger, it is best to book a dental assessment.
Common causes of sensitive teeth
Tooth sensitivity can have many causes, including:
- Worn enamel
- Gum recession exposing the tooth root
- Tooth decay or cavities
- Cracked, chipped or worn teeth
- Teeth grinding or clenching
- Recent whitening or dental treatment
- Acidic foods and drinks
- Brushing too hard or using a hard toothbrush
- Old or leaking fillings
When should you see a dentist for sensitive teeth?
You should book a dental check-up if sensitivity:
- Lasts more than a few days
- Keeps returning in the same tooth
- Is getting worse
- Happens with biting or chewing
- Comes with swelling, bleeding gums or bad taste
- Follows a cracked, chipped or broken tooth
- Wakes you at night or lingers after hot or cold triggers
Can sensitive teeth be a sign of decay?
Yes. Sensitivity can sometimes be an early warning sign of tooth decay, especially if it happens in one area, with sweet foods, or when food gets trapped near the tooth.
A dentist can check whether the sensitivity is from decay, exposed root surfaces, worn enamel, cracks or another cause.
Can gum recession cause sensitivity?
Yes. When gums recede, the root surface of the tooth can become exposed. Root surfaces can be more sensitive than enamel-covered parts of the tooth.
Gum recession may be linked to brushing technique, gum inflammation, grinding, tooth position or other factors. Your dentist can assess the cause and suggest suitable care.
What can you do at home?
While waiting for your appointment, you may be able to reduce sensitivity by using a soft toothbrush, brushing gently, avoiding frequent acidic foods and drinks, and using toothpaste designed for sensitive teeth.
Do not ignore sensitivity that is severe, worsening or localised to one tooth.
How can a dentist help?
Treatment depends on the cause. Your dentist may recommend desensitising products, a professional clean, fluoride treatment, a filling, repair of a cracked tooth, gum advice, a mouthguard for grinding, or other treatment if needed.
If sensitivity is caused by decay or a cracked tooth, treating it early may help prevent the problem from becoming more serious.
