Rapid action sensodyne
Rapid-action sensitivity toothpaste works by reducing fluid movement in exposed dentine tubules or blocking pain signals.
The short answer
Rapid-action sensitivity toothpaste works by reducing fluid movement in exposed dentine tubules or blocking pain signals. Rapid-action sensitivity toothpaste is a desensitizing dentifrice for exposed dentine. Its ingredients may reduce fluid movement through dentine tubules or dampen nerve response when used as directed.
Why does exposed dentine make teeth react to stimuli?
Sensitivity occurs when enamel or cementum no longer covers dentine, allowing temperature, touch, or sweet stimuli to affect the pulp nerves. A single sensitive spot can also come from decay, a crack, or a worn filling.
How should you use sensitivity toothpaste safely?
Brush gently with a soft brush and use the product according to its label. Spit rather than aggressively rinsing after brushing if the label advises this, and do not scrub the sensitive area.
When should persistent sensitivity be checked by a dentist?
See a dentist if sensitivity is severe, localised, spontaneous, or persists despite correct use. Examination can identify decay, cracks, gum recession, erosion, or an exposed restoration.
What should you ask about the toothpaste ingredients and cause?
Ask which ingredient is present, how it should be used, and whether your sensitivity has a structural cause. Ask if fluoride treatment, a filling, a bite adjustment, or another treatment is indicated.
