Hi, I would like to know if it is safe to gargle 3% Hydrogen Peroxide for teeth whitening? I also read about  Carbomide Peroxide (22%). Is this available in pharmacies?  Is it better than hydrogen peroxide? Please advise which is best, etc.Many thanks,
Hello thanks for consult at Chat Doctor.I suggest u go to the dentist for teeth whitening, by bleaching or u could also get veneers,u want home based, then u could go for teeth whitening toothpaste than these mouthwashes,avoid soft Chat Doctor.
