My gums were burned using a strong bleaching agent, I sent you my pictures, can you tell me what my options are?
From the fotos you sent me I can tell that you already had lost some bone and the gums had receded (the crown on your upper left lateral looked longer than normal in the picture of your teeth before the damage.
What exactly did they do to you?
Anyway, the only predictable option that you have is to do forced orthodontic eruption.
The tooth is slowly pulled out with orthodontic therapy and the bone and gums grow down with it.
At the end of the procedure you have to evaluate how short the root is, because as you pull the tooth down there is less and less root in the bone.
The tooth may have to be sacrificed(you said there was almost no tooth and the root had darkened). If the tooth has to be replaced because the root remaining is short then either a bridge(not recommended because the adjacent teeth are in good shape), or an implant supported crown(recommended) could be done.
Anything else you try will not be as predictable in giving you back the gum tissue at the right level, and irregular gum levels will make your smile less attractive.
Hope this helps you and good luck!
