If you’re unhappy with the color of your smile, you’ve likely tried a few OTC whitening products. Sadly, you didn’t achieve the results you wanted. In fact, you might not have noticed any improvement at all. OTC kits are ineffective because they don’t contain high concentrations of whitening agents. The only way to get the bright, beautiful smile you desire is with the help of your cosmetic dentist in Fargo. They’ll find the source of the discoloration to determine if you’re a candidate for teeth whitening or veneers.
