Why is my tooth turning black?
Common causes of a black tooth
A tooth can turn grey or black because of decay, an old knock or injury, a dead or infected nerve, or staining from old fillings and certain foods and drinks.
Surface staining can usually be removed with a professional clean. A tooth that has darkened from within often means the nerve has died, and it needs to be assessed by a dentist.
Do not ignore a black tooth, especially if you also have pain, swelling or a bad taste, because an infection can spread to the root.
If you have severe pain or swelling, contact our emergency dentist team.
