Reserve teeth whitening kit Start Kit, Beconfident, 10 ml Contains: 10 ml whitening gel for 10 treatments, 1 x user manual. How the product works: The product contains several active ingredients that work together. One of them is baking soda. The Beconfident whitening effect comes partially from the dissolution of the stains on the tooth surface as well as the oxidizing organic compounds that cause deeper discolorations in the enamel and dentin. The formulation consists of a combination of cleaning substances (surfactants, active surface agents) and free carbonates for active whitening released from the gel ingredient Beconfident 32% Sodium Bicarbonate. Unlike whitening products that contain hydrogen peroxide, which can cause irritation and pain, our active ingredients are mild and free of any negative side effects. The initial effect comes from the cleaning ingredients in the first two minutes of contact between the gel and the surface of the tooth. Surfactants lower surface tension and chemically bind to stains while removing them from the tooth. This process paves the way for the second phase, in which the temperature in the gel increases due to body heat. The increased temperature together with the natural enzyme in the saliva - alkaline phosphatase - separates sodium bicarbonate and forms free carbonates. Free carbonates oxidize - dissolve - the organic discolorations inside the enamel and dentin. These combined processes are patented (US 8580232 B2) and have a unique whitening effect. The products also contain 0.05% sodium fluoride to remineralize the enamel. In order for the gel to work effectively, the kit contains thermoformed mouthguards, which will be individually shaped by heating and can be reused for at least 5-6 complete treatments. The refill gel can be used to repeat the procedure when necessary. We recommend anyone to complete the entire whitening process until there is no gel left. It is best to do the treatment for 15 minutes for 10 consecutive days.
