Excess floride in drinking water can cause a yellow to brown discolouration of the teeth this is due to the change in the chemical composition of Enamel ( the outermost layer of the tooth)
Floride stains and discoloration are intrinsic in nature and will not dissappear after cleaning or Bleaching.
To permanently change the look of your teeth you may need to go for laminates or Veneers.
