1. To prevent dental hypersensitivity during and after treatment, Desensitize KF2% (FGM) (potassium nitrate at 5% and sodium fluoride at 2%) may be used prior to whitening, in a prophylactic character. The option of applying the desensitizer after whitening is also valid, however less efficient in certain cases. In both cases (prior to or after applying the whitener), Desensitize KF2% (FGM) should be applied to the teeth for 10 minutes. In cases of high hypersensitivity after the session, Desensitize 0.2% (FGM) (at-home use desensitizer) may be applied for 10 minutes into an individual mold, by the patient, on daily basis until the symptoms disappear.
2. Monitor patient throughout the whitening regarding dental hypersensitivity and possible spots of peroxide irritation in soft tissues. Cracks on the enamel or exposure of dentine may cause acute and intense pain. In these cases, we recommend interrupting the treatment, seeking corrective treatment prior to resuming.
3. If the whitening obtained does not meet the expectations, and the patient does not present hypersensitivity or other issues, you may reapply the product for up to two more sessions, totaling three sessions. If more than one session is required, consider a minimum interval between sessions of 7 days.
