What could cause a discolored front tooth in children?

Trauma or normal.: A blow to a primary tooth could cut blood supply to the tooth resulting in blood cells dying. They turn dark and are often absorbed into the internal of the tooth. Your dentist will want to x-ray the tooth to see if there is other damage or an infection.

Trauma: If a tooth gets hit, the nerve can die and the tooth can turn dark. Often no treatment is necessary unless pain and or swelling develop.

Trauma: Teeth have a blood supply and trauma may cause discoloration due to some minor bleeding inside the tooth. After initial evaluation this does not typically require treatment . Sometimes however the tooth becomes infected , symptoms to watch for are swelling or what looks like a pimple on the gum above the tooth. Is this case treatment is necessary.

Primary or permanent: If the tooth in question is a primary (baby) tooth there are mainly three possibilities. Trauma, it is ready to fall out, or decay. If the tooth is a permanent tooth it could be trauma, decay, or the fact that permanent teeth are a little darker than the primary teeth. Best to let a dentist examine the child to be on the safe side.
