Sensodyne relief pain
Sensodyne can help some dentine sensitivity by reducing fluid movement in open dentinal tubules, but it cannot treat decay, cracks, or infection.
The short answer
Sensodyne can help some dentine sensitivity by reducing fluid movement in open dentinal tubules, but it cannot treat decay, cracks, or infection. The likely source determines whether the tooth, gums, appliance, or product needs a different response.
What causes sensitivity from exposed dentine?
Dentine sensitivity occurs when enamel is thin or the root surface is exposed, allowing hot, cold, sweet, or touch stimuli to move fluid in dentinal tubules and activate nerve endings. A desensitizing toothpaste may reduce this response over repeated use, but pain from decay or a crack needs another treatment.
How can you care for a sensitive tooth at home?
Brush gently with fluoride toothpaste and a soft brush, and avoid aggressive horizontal scrubbing. Apply the toothpaste as directed, and report sensitivity that is limited to one tooth, occurs without a trigger, lingers, or is paired with biting pain.
When should persistent tooth pain be examined?
Have persistent, severe, localized, or spontaneous pain examined rather than masking it with toothpaste. Swelling, fever, a broken tooth, or a foul taste suggests a problem needing prompt care.
Could your tooth pain indicate decay or a crack?
Ask whether the pain fits dentine sensitivity or suggests decay, a crack, gum recession, erosion, or pulp inflammation. Ask which toothpaste ingredients and application method suit your mouth and restorations.
