[|Human|] Hi I have hard plaque on the back of my lower teeth.And the gums below my lower teeth are swollen.Sometimes it bleads when I bite into something.It bleeds all the time when I brush my teeth.I can see plaques between my lower back teeth too.I want to know what is happening to my teeth,what kind of food should I avoid and what should I do about this.Thank you.
[|AI|]  Hello, I have gone through your query and understood your concerns. You need to find out the actual cause as if you are a smoker then it may be due to nicotine stain and if you are chewing tobacco or related substances then also you will have same problem. If you are on phenytoin Chat Doctor.  If you were my patient I will suggest you vitamin C chewing tablets which will help you and good oral hygiene will also get you out from this problem. Hope this answers your query.
