My dc had a stainless cap fall off recently and her dentist said the tooth infected and needs to be pulled and a stainless spacer put in. My dc is almost 7. I have no idea if having the baby tooth pulled is warranted. She was also put on medicine for the infection. Any info would be greatly appreciated. I'd ideally like to avoid pulling the tooth. Also applying a sealant was recommended to her 6 year molars to prevent cavities but I'm not sure about having this done either. Any advice? Thanks.
