What is the direct answer?
Home measures may calm cavity pain briefly, but they cannot rebuild a cavity; a dentist must remove or manage the decay and restore the tooth when indicated.
What does this question mean?
Cavities are areas where acids from bacterial plaque have dissolved tooth mineral and may have formed a hole in enamel or dentine.
What can you do next?
Pain can be triggered when dentine tubules or the pulp react to cold, heat, sweetness, pressure, or bacterial inflammation.
When should you seek dental care?
Brush gently with fluoride toothpaste, clean between teeth, rinse after food, and avoid placing powders, oils, or aspirin directly on the gum.
What should you ask the dentist?
Book care for persistent or worsening pain, swelling, a bad taste, fever, or pain that wakes you; facial swelling and swallowing difficulty need urgent attention.
