I have a yellow intrinsic stain on my front tooth. It has been on my tooth ever since my front tooth came in. My dentists have never mentioned it before which is strange. It is a small stain but very noticeable. I have an another stain like it on another tooth but it's in the back so you can not notice. The stain is really embarrassing and I really want it removed. I also want to know what is is and how I can remove it if I can.
