Perfect Whites Smiles Malahide is the only teeth whitening clinic that offers free no-obligation consultation and a free follow up treatment to use within 6 months of the initial treatment performed. It means that if you think your teeth could be whiter or the result could last longer, you can receive a further teeth whitening treatment FREE OF CHARGE! In Perfect White Smiles we believe that laser teeth whitening and at home teeth whitening kits should be available to everyone.
