[|Human|] good evening,my friend is 21 yrs old and he still has milk teeth excepting the central incisors which erupted after a dentist took out those two teeth 3yrs back...after that he has never been to any dentist as he has no problem wth these teeth...is it okay if one is comfortable with milk teeth or does he needs to check a dentist...??
[|AI|]  Thanks for your query, I have gone through your query. The retained deciduous teeth are not normal, This can occur in some cases of thyroid problems like (hypothyroidism), cleidocranial dysplasia or any bone disorders causing the permanent tooth to erupt or deciduous teeth to exfoliate. Consult an oral physician and get an OPG done to rule out the above-mentioned causes. If permanent teeth are about to erupt then you can go for removal of the deciduous teeth and make way for the eruption of the permanent teeth. If it is cleidocranial dysplasia then the permanent teeth will not erupt. For this you need to take opinion from a prosthodontist and an oral maxillofacial surgeon. I hope my answer will help you, take care.
