<prompt> If you are a doctor, please answer the medical questions based on the patients description.i never went to the dentist in over 21 years. I then decided to take better care of my teeth and went and had all teeth cleaned and checked for cavities. I had 1 cavity after 21 years. now i have been going to the dentist twice a year for cleaning and checkup. Last visit revealed 6 cavities. How do i go from 1 cavity in 21 years to 6 cavities in about 212 years ?  <response>: Hi With you query, as such with your question two possibilities can happen:1. Maybe the dentist could not find the other cavities which might be due to initial lesionscavities. 2. your diet and oral hygiene habits which play a major role might be another cause. Cavities donor become too many in an Asian of 6 months it takes time but your oral hygiene and food plays a major role in increasing the cavities. Maintain good oral hygiene with proper brushing technique and get all the instructions from your dentist too. Hope this helps you
