A twinge in a tooth with a cold drink or when eating something sweet is very common. Some measures at home can give temporary relief, but unless the underlying cause is treated, the complaint may return.
Why do teeth twinge?
- Root surfaces exposed by gum recession
- Enamel wear (hard brushing, acidic drinks, clenching)
- Tooth decay
- A broken or cracked tooth
- Temporary sensitivity after a new filling or whitening
- Gum inflammation
What you can do at home
- Toothpaste for sensitive teeth: Toothpastes with ingredients such as potassium nitrate or stannous fluoride can reduce sensitivity within weeks when used regularly. For details, see our article on toothpaste for sensitive teeth.
- A soft brush and the right technique: Brush without pressing, using small circular movements.
- Rinsing with warm salt water: Can be soothing for gum-related discomfort.
- Avoiding triggers: Limit very cold, very hot, acidic and sugary foods and drinks for a while.
- After acidic drinks: Rinse your mouth with water and wait about 30 minutes before brushing.
- Painkillers: If needed, you can take a painkiller you have used before without problems and that suits you, following the leaflet; do not use it for long, and ask your pharmacist if in doubt.
What to avoid
- Placing aspirin or any other tablet on the painful tooth or gum (it can burn the tissue)
- Rubbing substances such as alcohol, vinegar or baking soda directly onto the gum
- Applying a hot compress (it can increase swelling if there is an infection)
- Suppressing pain with painkillers for a long time
When should you see a dentist?
- If the twinge lasts more than a few days or gets worse
- If the pain continues after the trigger is removed
- If the pain starts on its own, throbs or wakes you at night
- If there is swelling of the face or gum, or a fever
- If you feel a sharp pain when biting
These signs may point to conditions that need treatment, such as decay, nerve inflammation or a cracked tooth. For more on the causes of sensitivity, read our article why do teeth become sensitive?
