<s>[INST] My 6 year old has silver caps on all his molars. One if his molars with the cap was coming completely loose. He is getting some other molars in and I thought because of those it may have loosened the cap. Well now it s completely off with the tooth inside it. I m thinking it s an infection because the area looks inflamed. He is not in any pain but is this common for the molar to come out at well at such a young age? [/INST] Hi your child is 6 yrs (mixed dentition stage)and it's the age of eruption of the first lower permanent molar tooth. Since you haven't mentioned how long has the present tooth been capped I am presuming it to be a primary tooth, which is actually approaching it's time to shed off in a couple of months to a year time. I suggest you to visit a dentist who will evaluate the stage of exfoliation of the particular tooth. The cap can be refined if there is still time. Regarding the inflammation you mentioned, it is a very common symptom while tooth eruption, and it can be put on limit by proper cleaning regimen both by parental supervision and professional help by a dentist. Hope this was helpful. Take care. </s>
