I have tried just about all the over the counter bleaching products. I notice some whitening. But just not as white as I would like. The girl I worked with has a retainer from her Orthodontist. All she had to do was by the tube of whitening jell from the dentist. A lot cheaper that way. I think her retainer is a whole piece not the metal wire ones. The dentist whitening is amazing. She used it three times and her teeth are almost too white. |
