<s>[INST] I have a 6 yrs daughter. There's a hole behind her tooth located in the front. Her tooth is loose but I don't see a tooth coming thru. The hole looks a like a tooth fell out. It doesn't really hurt her. She noticed it today, will call her dentist tomorrow, should I be worried? [/INST] Hello, Welcome Thanks for consulting HCM,    I have gone through your query, you have small child that she had small hole, her tooth can be carious or loose tooth is due to it is primary tooth, permanent tooth erupting causes mobility of Primary tooth , dont worry , go to dentist for Oral hygiene examination .  Hope this will help you.   Wishing her good health  Regards    Dr. Priyanka tiwari </s>
