My 6 yr old has his bottom teeth coming up - they are coming up behind his other teeth instead of directly under it - the one on the left took some time to fall out but it did on its own - the other one is up but the front tooth wont budge!

His dentist says this happens time to time and to that he may need to help the tooth come out - problem is DS has anxiety and freaks out at the dentist so I dread taking him back - any ideas how to get that tooth loose on our own??
