I had the smallest spot on my tooth that was from a small filling that fell out. (from a bad dentist and unnecessary) But anyways, I got it refilled but really contemplated leaving it. But I have a new good dentist who used microblasting. But I am so worried that it will fall out and then I will not be able to find a new dentist that uses the microblasting tool. (this dentist will retire in 10 years) and I really dont want this tooth to be drilled. Should I just leave it when it falls out. Or can I find another dentist who uses that technique?
