This method involves using light ray of a particular wave-length for heating and activating the chemical components of the whitening gel, which allows them to penetrate through tiniest enamel pores to reach the underlying dentin much easier. As a result, after a one-hour treatment, your teeth get lightened by 4 shades or more. It is difficult to anticipate any exact outcome in the beginning of the procedure; it depends solely on your individual characteristics. Teeth with a yellowish shade or dull-colour teeth can me lightened most easily, whereas grayish-shaded and translucent are lightened less easily.
The technique of photobleaching:
The treatment itself takes 60 minutes (three sessions each lasting 20 minutes), but you will have to stay in the chair with your mouth open for not less than 2 hours, as the procedure involves some preparations (thorough isolation of the oral cavity mucous membrane in order to prevent its burn); it will also take time to wait for the lamp to cool down and heat up again between the sessions. Before each session a new portion of gel is applied to teeth. At the end of the procedure a remineralization agent is applied to lower teeth sensitivity.
Take-home and in-office teeth whitening using the innovative “Opalescence” technology
We offer take-home low-concentration, professional, internal and combined whitening using the innovative ‘Opalescence’ technology. Teeth lightening by one-two shades can be achieved, if compared to the initial teeth shade. After whitening special varnish is applied. Then, all the restorations and fillings found on external teeth surfaces are changed according to the new teeth shade.
Teeth whitening is a procedure that helps to whiten or lighten teeth, remove stains and discolourations.
