We asked our dentist. You can also ask his pediatrician. If he has a large cavity and it needs to be treated, I would be making a lot of calls. I would not want the tooth to be lost. I'm glad he's on antibiotics, though, because a tooth infection can become systemic. The other thing you can consider is paying upfront (being out of network) and filing with any insurance you have. You might also find out if any medical insurance he has (not dental) will cover any of the procedure or medications. He may end up needing to be treated at the hospital, as they often do not do sedation for small children anywhere else.
