How to make a cavity stop hurting
A cavity can be calmed temporarily by rinsing, gentle brushing, avoiding triggers, and using an appropriate pain reliever, but the damaged tooth needs.
The short answer
A cavity can be calmed temporarily by rinsing, gentle brushing, avoiding triggers, and using an appropriate pain reliever, but the damaged tooth needs dental treatment to stop the disease and restore its structure.
How can you temporarily calm pain from a cavity?
A cavity is a carious lesion in enamel or dentine caused by acid produced when plaque bacteria use fermentable carbohydrates. As the lesion advances, it may irritate the pulp and cause sensitivity or toothache.
How will the dentist assess the damaged tooth?
The dentist examines the surface, checks the pulp and bite, and may take an X-ray to assess hidden damage. Treatment can range from preventive remineralisation to a filling, root canal treatment, or extraction when the tooth cannot be restored.
What can you do at home to calm cavity pain?
Clean gently with fluoride toothpaste, floss around the tooth, rinse with water after food, and avoid repeatedly exposing the area to sugary or acidic foods and drinks. Do not place aspirin directly on the tooth or gum.
When should ongoing cavity pain be checked?
Make a dental appointment if pain lasts, returns, wakes you, or is triggered by heat, cold, or biting. Swelling, fever, pus, or difficulty swallowing or breathing needs urgent care.
What should you ask about the cavity and X-ray?
Ask how deep the lesion is, whether the pulp is involved, and what the X-ray shows. Ask which restoration will preserve the tooth and how to prevent new lesions.
