Hi. I have many dental problems. 1) my 2 lower molars are missing due to cavity. I lost them 3 years back. 2) my front teetch is arched outside, so I want to add clip. Smiling is not a good idea for me. 3) my upper pre-molar is decayed, it is paining everyday, pain killers doesnt even reduce the pain. So, now I need either to fill it with amalgam or remove it as well. I need your suggestion. Thank you.
