<s>[INST] Hi, My name is Deepak. My teeths shape are changing lower teeth are touching to the upper teeth gum. Some time upper teeth touching lips and touching parts become blondish. These things i have absorbed previous 5 month. I want to know why these problem started what is the solutions. [/INST] Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your complaint touching of lower teeth to the upper gums is seen in a condition known as Deep Bite but if it has started happening from a few days and was not evident previously then it is possible that there is reduction in the vertical height of jaws due to loss of back teeth known as Molars and with the loss of molars the vertical height gets reduced, and front teeth starts touching. There can also be protrusion of upper front teeth as a result of periodontal diseases which can lead to loosening and mobility of teeth . You should consult an oral physician and get evaluated so that he can bale a correct diagnosis and plan a proper treatment as per the condition of the teeth. Hope this information helps. Thanks and regards. Chat Doctor. . </s>
