qqp question1: I extracted 4 molar teeth because the dentist said my teeth are over-crowded. I was too busy at work to get a second opinion and ended up removing the 4 teeth. I now feel worried about it. Are there any side effects of this? Will it affect my health in any case? question2: My diastema is too high. The gap between 4 front teeth is about 2cm each. How can it be treated?
