Sensodyne rapid relief toothpaste for toothache
Sensodyne Rapid Relief may help exposed-dentine sensitivity, but it cannot treat decay, a crack, inflamed pulp, or an abscess.
The short answer
Sensodyne Rapid Relief may help exposed-dentine sensitivity, but it cannot treat decay, a crack, inflamed pulp, or an abscess. A dentist uses the examination findings to identify the cause.

What is the direct answer?
What does this question mean?
The clinical subject is desensitising toothpaste. Possible causes include dentinal tubules, potassium salts, arginine, exposed dentine. The appearance or symptom alone does not establish a diagnosis.
What can you do next?
Do not use it to delay care for swelling. Keep the area clean, record changes, and arrange the appropriate dental examination. Treatment is selected after the cause and anatomy are assessed.
When should you seek dental care?
Seek prompt care for worsening pain, swelling, fever, pus, or a persistent change. Emergency assessment is needed for difficulty breathing or swallowing.
What should you ask the dentist?
Ask about whether the pain is sensitivity or deeper tooth disease. Ask which examination, imaging, laboratory test, or treatment is appropriate and what follow-up is needed.
Frequently asked questions
Can this be diagnosed at home?
No. Different dental causes can look or feel similar, so examination is needed.
What determines treatment?
The findings from the history, clinical examination, and any indicated tests determine treatment.
