At regular cleaning, dentist discovered small abscess on my son's 1st molar. He has a previous filling in this tooth. The dentist called in antibiotic and plans to extract in 7-10 days followed by a space filler to prevent movement. Is extraction necessary? It sometimes seems like every time we go they want to do a procedure while the kids have no pain and few cavities. I've heard complaints from other parents that this company (has multiple offices almost like retail dentistry) does unnecessary procedures. I love the dentist we see but this is my baby and he doesn't react well to any intrusion on his person and will not handle this well even fillings are rough. Is it necessary to remove a tooth like this instead of treating the abscess and seeing if it returns?
