Sensodyne rapid and protect
Sensodyne Rapid Relief and Repair & Protect toothpaste are designed for sensitive teeth, with different active ingredients and use instructions.
The short answer
Sensodyne toothpastes for sensitivity reduce dentine sensitivity by blocking exposed tubules or calming nerve response, while brushing supports plaque control.
What do sensitivity toothpaste product names describe?
The product names refer to toothpaste formulations intended for dentine hypersensitivity, which occurs when enamel or gum tissue no longer shields dentine. Ingredients can include potassium salts, fluoride, or an arginine-based tubule-blocking system, depending on the exact regional formulation.
How should you use sensitivity toothpaste safely each day?
Brush twice daily with a soft brush and a fluoride toothpaste, using gentle pressure and following the pack directions for the product you bought. Spit after brushing rather than rinsing repeatedly, and avoid brushing immediately after acidic food or drinks.
When does tooth sensitivity require a dental examination?
Arrange an examination if pain is localised, spontaneous, lingering after hot or cold, triggered by biting, or accompanied by swelling. A dentist may inspect for decay, erosion, gum recession, an exposed root, a defective filling, or a crack.
How can a dentist identify the cause of sensitivity?
Ask whether the sensitivity is dentine hypersensitivity or a tooth-specific problem, which formulation is appropriate for you, and whether fluoride exposure or brushing technique needs changing. Also ask what treatment would protect an exposed root or restore damaged tooth structure.
Frequently asked questions
Can sensitivity toothpaste replace a dental check?
No. It may reduce general sensitivity, but a new or one-sided symptom can come from decay, a crack, or gum disease.
How should I choose between products?
Compare the active ingredient and directions on the local label, then ask a dentist or pharmacist if you have persistent symptoms or special medical needs.
