I'm currently wearing braces however just one tooth has been losing gums. i told my orthodontist once he said it was normal because that teeth was ove

He may be right: Sudden loss of gum tissue can idicate a structural problem with the gums. Seek advice of a periodontist because continue rapid recession can lead to loss of a tooth. However your othodontist may be correct. It does not hurt to get the opinion of a gum specialist.

NORMAL: The eye tooth- cuspid has an oval contour at the gum line so the wire is impinging on part of the gum-unlike the other teeth that are flatter.

Not usual but possib: Recession can be caused from a number of things during orthodontic tooth movement. Evaluation of contact with opposing tooth, brushing habits, position of tooth with respect to the bone in which it lies, as well as initial presentation of tooth and bone and track of movement are all things that need to be evaluated. A periodontist is the best specialist to evaluate this for a second opinion.

Periodontist: If you are concerned about your gum health, see a periodontist and ask them to consult with your orthodontist and work on your case collaboratively.

Could be normal: If the gum loss is between the teeth it is probably due to repositioning an overlapped tooth. The gum is in the same place, but the tooth has moved so the narrow neck of the tooth is no longer touching the adjacent tooth opening a space between the contact point of the tooth and the gum. If it is on the facial surface, then it is true recession and may need a gum graft.

See a periodontist: It is not "normal" for teeth to loose gum tissue during orthodontic treatment. You should see a gum specialist (periodontist).

Not normal: Bone loss is not normal. It may be an acceptable compromise considering the exigencies of your malocclusion, but it is to be avoided if possible. Discuss this again with your orthodontic specialist and with your general dentist. Perhaps consultation with a periodontist is in order.
