Patients who want to opt for this procedure are required to have a dental checkup beforehand in order to see if laser teeth whitening is the right solution for them. The dentist may advise other treatments before undergoing this procedure. It’s also important to clarify what results can be achieved and how many sessions will be required – some patients may require multiple sessions before achieving their goal. Patients with other dental issues such as cavities will be required to treat these first before undergoing laser teeth whitening.
Laser teeth whitening starts with the isolation of gums and lips (for protection reasons) followed by the application of a special gel on the surface of teeth. The professional gel will be activated with the laser’s light, giving a whitening effect. The laser technology allows the dentist to be very precise and save the bone structure of the teeth. The operation is pain free and it lasts around 60 minutes. If during the operation the teeth become too sensitive, the process can be continued in another session. At the end of the procedure, the patients will be able to see the effects immediately.
There is no recovery period associated with laser teeth whitening. The patients can go back to their routine activities immediately after the procedure is done.
