Can sensodyne stop toothache
Sensodyne can reduce sensitivity from exposed dentine, but it does not treat decay, pulp inflammation, cracks, or dental infection.
The short answer
Sensodyne may reduce dentine sensitivity, but it cannot reliably stop toothache caused by decay, an inflamed pulp, a crack, or an abscess. It is a desensitising toothpaste, not a treatment that repairs a damaged tooth or removes infection.
What is the direct answer?
What does this question mean?
Dentine contains microscopic tubules that can transmit movement of fluid toward the pulp when exposed to the mouth. Formulas may use ingredients such as potassium salts or arginine to reduce sensitivity signals or block tubules, while pain from the pulp has a different mechanism.
What can you do next?
Use a soft brush and fluoride toothpaste without aggressive scrubbing, and follow the product label. Do not use temporary relief to postpone an examination if pain is spontaneous, lingers after temperature changes, hurts on biting, or is accompanied by swelling.
When should you seek dental care?
Book prompt dental care for persistent toothache, a visible cavity, a broken tooth, night pain, lingering hot or cold pain, or swelling. Seek emergency care for facial swelling with difficulty breathing or swallowing.
What should you ask the dentist?
Ask whether the pain is sensitivity or pulp inflammation, and whether the tooth needs a filling, protective restoration, root-canal treatment, or another procedure. Ask how the diagnosis was made and which symptoms mean the condition is worsening.
Frequently asked questions
Can Sensodyne help a cavity?
It may lessen sensitivity temporarily, but a cavity still needs examination and appropriate restorative treatment.

Brush gently with it as directed on the label and avoid forceful brushing around the sensitive area.
