How much does Maxwell weigh? I would be most concerned about anesthesia on a tiny dog. He's 1 year old now, right? My thoughts are...get a thorough vet check-up for pre-op testing. Explain your fears to your vet...make certain they use the proper anesthesia for a Yorkie(do a search on here, I know this has been discussed). But really at a year old I doubt that they are going to just fall out on their own...I could be wrong...but I don't think so.
Anyway, Winston and Spencer both had retained baby teeth...they both had them surgically removed and they both survived the procedure.
You must have confidence in your vet, you must be able to openly speak your mind to them...they must understand your fears and work with that.
Good luck to you and Maxwell...I hope everything works out for the best.
