About a 6 months ago I had a filling on a almost unnoticeable cavity on my front tooth which meant drilling into two teeth. After a few months I noticed a yellowish tint was appearing all around the circular filling and at this point its becoming quite noticable. I would just go back to the dentist but it is now closed and I don't have the money to pay in the first place. Is there anything I can do to at least temporarily fix the problem? A responce would be greatly appriciated.
