Best medicine for teeth sensitivity
Tooth sensitivity is usually managed by removing its cause and using desensitizing toothpaste, with dental treatment when dentin is exposed.
The short answer
There is no single best medicine for tooth sensitivity: desensitizing toothpaste containing potassium nitrate or fluoride can reduce nerve response, while a dentist treats the cause, such as decay, recession, or an exposed filling.
Why does exposed dentin make teeth feel sensitive?
Sensitivity occurs when enamel or cementum no longer shields dentin, the porous layer beneath. Cold, heat, sweet foods, touch, or air can move fluid in dentin tubules and trigger pulp nerves; lingering or spontaneous pain suggests another problem.
What can you do daily to reduce tooth sensitivity?
Use fluoride desensitizing toothpaste twice daily, brush gently with a soft-bristled brush, and limit acidic drinks. A dentist may apply fluoride varnish, seal exposed root surfaces, repair decay, or adjust a restoration.
When should tooth sensitivity be examined by a dentist?
Arrange an examination if pain is localized, worsening, lingers after the trigger, occurs without a trigger, or comes with swelling, a broken tooth, or fever. Facial swelling or trouble swallowing or breathing needs urgent care.
What should you ask about the cause of tooth sensitivity?
Ask whether recession, erosion, a crack, decay, or a restoration is responsible, and whether the pulp needs testing. Ask which desensitizing ingredient and professional treatment fit the affected tooth.
