That sharp, sudden twinge when you sip something cold or bite into something sweet is tooth sensitivity. It is very common and, in most cases, very treatable.
Sensitive teeth happen when the protective enamel wears down or the gums recede, exposing the inner layer of the tooth. Causes include hard brushing, acidic foods, grinding, gum recession and decay. Desensitising toothpaste, a soft brush and a dental check-up usually resolve it; the dentist can treat the underlying cause if needed.
Common causes
- Brushing too hard or using a hard-bristled brush.
- Acidic foods and drinks wearing down enamel.
- Gum recession exposing the tooth root.
- Teeth grinding, cracks or untreated decay.
What you can do at home
- Switch to a soft brush and brush gently.
- Use a desensitising toothpaste daily.
- Cut back on acidic and very cold or hot foods.
- Do not brush immediately after acidic foods - wait 30 minutes.
When to see a dentist
If sensitivity is severe, sudden, or focused on one tooth, see a dentist. It can signal decay, a cracked tooth or exposed nerve that needs treatment such as a filling, bonding or, occasionally, a root canal.
