Whitening principle of tooth whitening gel There are two major categories of effective components of the tooth whitening gel.
1. Peroxides: urea peroxide, urea peroxide, or peroxamide, and hydrogen peroxide (also known as hydrogen peroxide).
2. Non peroxides: sodium perborate, sodium chlorite and sodium percarbonate. The whitening principles of these effective components are all consistent, and in normal oral environment, oxygen free radicals will be dissociated. The oxygen free radical can undergo redox or complexation reaction and pigment molecules, organic pigment by carbon reduction ring structure married aqueous pigment small molecular structure, small molecules gradually move out, spread to the tooth surface, with saliva, or in mouthwash, brushing process from the teeth to remove the tooth surface of pigment the purpose of.What are the various concentrations of the whitening gel applied to each other?
(1) commonly used concentrations are 16%CP, 22%CP, 35%CP, 44%CP, 6%HP, 16%HP, 22%HP and 35%HP. These are peroxide whitening adhesives, CP refers to carbamide peroxide, HP refers to hydrogen peroxide.
(2)The concentration of whitening glue determines the efficiency, the concentration is high, the effect is fast, the concentration is low, and the effect is slightly slow. But the concentration is high, there will be some irritation of the mouth, the irritating people are also It differs from man to man, individual differences, the sensitivity of every one of your teeth and gums are not the same, the professional dental or professional beauty salons can use high concentration hydrogen peroxide whitening gel, preferably with gum protective agent.
(3) the tooth whitening family suit suggests using 22%CP below concentration, such as 16%CP, 22%CP, 6%HP or NP, with low concentration, and use for 25-30 minutes at a time, and insist on 14 days. The effect is the same as that of high concentration whitening gum.
