Q. My dentist refered me to an orthodontist for overcrowding. When i went to see the orthodontist he said that I could have braces (train track) on my upper teeth following 2 extractions, as my front teeth are slightly gowing back and the two teeth either side are protruding outwards, i believe he said it was a grade two. He also mentioned that as on my left side the gum has receded due to the tooth protruding and I may or may not require an operation to correct this but would only be able to tell after having the braces on. I was just wondering if youcould advise if any other treatment maybe applipcable so Icould look into it further.
