Supervised at-home whitening with 10% hydrogen peroxide

Author: Dr. Felipe Rossi.

30-year-old female patient.


Dark shade of teeth.


Initial anamnesis was carried out in which the patient did not report any sensitivity and no previous attempts to whiten teeth. The clinical examination showed a healthy periodontium, absence of anterior restoration and no cavities. The initial shade taken was A3 in the lateral and central teeth and A 3.5 in the canine.


The proposed treatment accepted by the patient was a supervised whitening treatment with trays and hydrogen peroxide gel (Wīt Essential Xtra 10% – FGM) with the duration of 45 minutes to 1 hour per day of exposure, during 28 days.

We made silicone trays and guided the patient about the use of the whitening gel without diet restrictions and without prohibiting food coloring. 21 days later, the patient reported local sensitivity and the use of Dessensibilize 0.2% desensitizer was recommended for 10 minutes per day, applied in the same tray of the whitening gel. 28 days later, we noted a very satisfactory result with final shade BL3, absence of sensitivity and with positive feedback from the patient reporting comfort during the whole process.
