I wouldn't recommend Brite Smile. I mean they did a good job but for at least 24 hours my teeth were more then sensitive. I couldn't talk, breath with an open mouth............just any air on my teeth was feeling terrible.
You mentioned, that you trying to rebuild your gums, how is that possible? My gum line is going back so bad on my front teeth, I'm so scared. I asked the dentist and he said he could put fillings on it.....but that's something I don't want to do.
