>>12571523Teeth are naturally yellow. The underlying dentin is even more yellow, and the glassy transparant enamel only dilutes the color a little bit. There are plenty of whitening procedures available, but many are shitty and scar the enamel to make it less transparant.
The gold standard of teeth whitening is 10% Carbamide peroxide, in individually shaped trays that fit snugly onto your teeth. Dentists can usually do this procedure for you inexpensively, you just put the gel into the trays and fit them onto your teeth for 30 min or overnight.
It's a good idea to have been examined by a dentist before your whiten, because you could have erosive damage or caries that needs to be treated before whitening.
