3% Hydrogen Peroxide Gel

Figure 1 | Although 3% hydrogen peroxide is generally associated with tooth whitening, it was originally used as an oral antiseptic for improving gingival health.1 It breaks down and loosens dental plaque and calculus, which can improve overall gingival health in patients at risk of periodontal disease.2-4

One problem is administering hydrogen peroxide into the periodontal pocket and keeping it in contact with the tissues long enough for it to work. However, local administration of 3% hydrogen peroxide gel using customized, in-office fabricated trays enables it to penetrate into deeper pockets, improve pocket depths and bleeding on probing, and break down plaque and calculus.5,6

To enable delivery of a 3% hydrogen peroxide gel, such as Poladay from SDI, directly to tissue in a safe, effective, affordable way, clinicians must determine that the patient is a candidate for at-home hydrogen peroxide therapy with a thorough initial examination and medical/dental history, and take detailed and accurate impressions for well-fitted custom trays.

When delivering a set of custom trays and 3% hydrogen peroxide gel to a patient, it is important to demonstrate how to properly load the tray with the gel and seat the tray(s) in the mouth. There should also be a proposed treatment regimen and observed gingival health improvement at a follow-up appointment.

Although there are many therapies for treating periodontal disease, hydrogen peroxide has been shown to break down dental plaque and calculus, clean gingival tissues, and eliminate bacteria. Using custom-fit, in-office fabricated trays and Poladay 3% hydrogen peroxide gel, patients can receive personalized, affordable treatment to improve oral health.
