Over the counter tooth sensitivity treatment
Sensitivity toothpaste with a desensitising ingredient can reduce cold or sweet pain while the cause of exposed dentine is assessed.
The short answer
Sensitivity toothpaste containing potassium nitrate or stannous fluoride can reduce dentine sensitivity, but it does not repair decay, a crack, or gum recession. Use it as directed on the label and keep brushing gently with fluoride toothpaste.
What is the direct answer?
What does this question mean?
Sensitivity occurs when dentine beneath enamel or cementum is exposed and temperature, sweetness, or touch reaches fluid-filled tubules leading toward the pulp. Common contributors include worn enamel, recession, abrasion, erosion, decay, and a leaking filling.
What can you do next?
Brush twice daily with a soft brush and fluoride sensitivity toothpaste, using light pressure and avoiding immediate acidic drinks after brushing. A dentist can apply fluoride varnish, a dentine sealant, or a bonded covering after identifying the cause.
When should you seek dental care?
Arrange an examination when sensitivity is limited to one tooth, persists despite routine care, causes spontaneous pain, or follows trauma. Swelling, fever, lingering heat pain, or pain on biting can indicate deeper inflammation or infection.
What should you ask the dentist?
Ask whether the pain comes from exposed dentine, decay, a crack, recession, or the pulp. Ask which ingredient and brushing technique suit you and whether a fluoride treatment, sealant, restoration, or root canal assessment is needed.
Frequently asked questions
How long should sensitivity toothpaste be used?
Use it consistently according to the product directions and seek an examination if symptoms persist or worsen.
Can sensitivity be treated at home permanently?
Home care may reduce symptoms, but lasting treatment depends on the cause, such as decay, recession, erosion, or a crack.
