Oral b sensitive
A sensitive-teeth oral-care routine uses a soft brush, fluoride toothpaste, gentle pressure, and a desensitizing ingredient such as potassium nitrate.
The short answer
A sensitive-teeth oral-care routine uses a soft brush, fluoride toothpaste, gentle pressure, and a desensitizing ingredient such as potassium nitrate or stannous fluoride.
Why can teeth become sensitive to touch or temperature?
Sensitivity happens when hot, cold, sweet, or touch stimuli reach dentin through worn enamel, gum recession, cracks, or decay. A sensitive toothpaste can reduce transmission through dentinal tubules or calm nerve activity, but it cannot repair a cavity or crack.
How should you brush when your teeth are sensitive?
Brush twice daily with a soft brush and spit without vigorous rinsing. Apply a small amount of desensitizing toothpaste to a sensitive spot if directed, avoid acidic habits, and clean between teeth gently.
When should new or worsening sensitivity be assessed?
Arrange care if sensitivity is new, localized, worsening, lasts after the trigger, or occurs with swelling or a broken tooth. The dentist may use air or cold testing, inspect the gum line, and take an X-ray.
How long might sensitive toothpaste take to help?
How long should sensitive toothpaste take to help? Improvement varies, and persistent symptoms need diagnosis rather than repeated product changes.
