[|Human|] As much as I hate to admit it, I never brush my teeth; lie once in a blue moon do I actually do it, and now I think I m paying the price. I have this white chalky stuff on my two bottom middle teeth just above my gums and it never comes off. I fear that those teeth may be rotting. And I just today noticed a black dot on one of my molars. There is no sensitivity or pain to it at all, but it didn t brush away. Could you please help me with my problem?
[|AI|]  Hello and welcome to Chat Doctor forum, i would like to inform you that maintaining your oral hygiene is very important, if you were not serious about it till now then start brushing your teeth regularly, white and black spots over your teeth are an indication that caries has initiated and if you do not take proper care of your oral hygiene then the caries will spread further, initially there is no pain or sensitivity but gradually caries spreads, and you will face problem, so kindly start using fluoridated toothpaste and a soft bristle tooth brush, brush your teeth twice daily.I wish you good health, take care.
