Hi Doc.! I Realize That When I Eat Certain Kinds

Hi Doc.! I realize that when I eat certain kinds of foods I have an after taste in my mouth which is not so pleasant. I also notice that when I use certain kinds of seasoning that happens. I went to the dentist and he told me that it is because I have an overgrowth of taste buds. I would like to know what causes this and if it can be corrected or controlled.
