Q. I am considering having my teeth whitened, but was told a few years back that this would not work for me. As a child I was on a long course of antibiotics for a tonsil infection which was they were subsequently removed. I was long use of antibiotics can cause the teeth to yellow and teeth whitening unfortunately would not help this. They are not terribly yellow and I am not a smoker or heavy coffee or tea drinker, so wanted to know is this true, am I unlikely to see any result at all? thank you!
