What could be the possible reasons for dental discolouration in children, what can be done about it and how much would it cost? (photo)

A tooth may become discoloured for reasons other than a dead/infected nerve. After a traumatic injury, the nerve (which is still alive) may lay down scar tissue internally, causing the tooth to become more yellow over time. Other causes of discolouration include external staining from: Dietary sources Tobacco stains Fluorosis Abnormal enamel development/maturation Deposition of tetracycline antibiotics within the tooth Before the nerve dies completely, the internal bleeding from the nerve tissue stains the tooth a dark grey or brown colour.

Crowns can correct more severe tooth discolouration than veneers because they can be made thicker without affecting how well the crown can stay on the tooth. Veneers should be bonded to mostly (or only) enamel for the best chance of long term success (the veneer not falling off or staining at the edges). To ensure that enamel remains after tooth preparation, only about 0. 5mm of tooth structure can be trimmed off.
