Will my tooth change colour after root canal treatment?
Teeth sometimes turn grey after root canal treatment. This is often a result of the medicated pastes that the dentist uses to clear the infection inside the tooth. For many back teeth, this is not a problem as they are not very visible. For a front tooth, turning grey may not match other front teeth. Ask your dentist about internal bleaching to help restore the tooth's natural colour. Otherwise, a crown or veneer may be needed to mask the colour and match the other teeth.
