[|AI|]  Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your query as your son is 7 years of age that is a mixed dentition stage that means when some milk teeth are present and some permanent teeth. As he has some lost milk teeth and permanent teeth are erupting it means his milestones are going on well. So do not worry as gradually the milk teeth will fall, and permanent teeth will erupt. As far as blackening and breaking of teeth is concerned it is due to severe decay in teeth. For this you should consult a Periodontist and get appropriate treatment done as per the condition of teeth. Hope this information helps. Thanks and regards. Chat Doctor.
