What could a black hole or pit in your tooth mean?
A dark hole or pit in a tooth is often decay, but a lost filling, stain, or fractured enamel can look similar and needs examination.
How can decay create a dark hole in a tooth?
A cavity is a damaged area where acids from plaque dissolve enamel and may reach dentine. A filling, crown, or root-canal treatment is chosen after the dentist checks depth and pulpal status.
What should you do when a tooth has a dark opening?
Rinse, brush gently with fluoride toothpaste, and avoid picking at the opening or placing household material in it. Note sensitivity to cold, sweets, biting, or heat because those patterns help locate the problem.
When does a dark hole in a tooth need treatment?
Arrange care soon for a visible hole, food trapping, or toothache. Urgent care is needed for facial swelling, fever, or difficulty swallowing or breathing.
What should you ask about a dark tooth defect?
Ask whether the defect is decay, a lost restoration, or a crack, and whether an X-ray is needed. Ask which tooth structure can be preserved and how it will be restored.
