Medicine for sensitive teeth pain
Sensitive teeth pain often improves with desensitizing toothpaste, but persistent or severe pain needs a dental examination to find its cause.
The short answer
Desensitizing toothpaste containing potassium nitrate or stannous fluoride can reduce sensitivity, while persistent pain needs a dental examination.

How do exposed enamel or dentine trigger sensitivity?
Sensitivity occurs when enamel is thin or dentine is exposed, allowing temperature or touch to stimulate nerves through tiny tubules. A cavity, worn filling, crack, gum recession, or exposed root can cause similar pain and needs different treatment.
How should you apply toothpaste for sensitive teeth?
Use a soft-bristled brush with gentle pressure and apply a small amount of desensitizing toothpaste to the sensitive area before bed. Avoid very acidic foods for now, and do not place aspirin directly on the gum because it can injure the tissue.
When should persistent sensitivity be examined?
Arrange an examination if pain is localized, worsening, spontaneous, or continues after the trigger is removed. Facial swelling, fever, difficulty swallowing, or difficulty breathing requires urgent dental or medical care.
What could be causing this tooth sensitivity?
Ask whether the pain comes from exposed dentine, decay, a crack, gum recession, or an inflamed pulp, and what tests are needed. Ask which toothpaste or fluoride treatment suits you and whether a filling, root canal, or gum treatment is indicated.
Frequently asked questions
How long does sensitive toothpaste take to help?
It may require repeated use because the ingredients reduce nerve response or block dentine tubules over time.
Can sensitivity mean I need a filling?
Yes. If decay, a defective filling, or a worn area exposes dentine, a dentist may repair it rather than treating sensitivity alone.
