We live in an age when appropriate appearance and suitable looks are an absolutely important part of our everyday life. It is in our own interest to provide for health prevention, regular and proper personal hygiene. It is not a physical nor a chemical treatment, and it does not have any harmful effects on the dental enamel. The treatment is based on optical principle: the chain resulted from the stain between the sheets of the dental enamel is torn to its molecules thereby enabling the light to freely move. The result is brighter teeth by 4-8 shades, which may last for 1-3 years depending on the life style. Treatment is performed in a pleasant environment on a single occasion, and takes only one hour altogether. In order to achieve the expected result a mouth hygienic pretreatment is required. Regular scaling of teeth and polishing in itself is essential for health prevention. Following the colour identification a 1-2 mm thick tissue friendly, pH-neutral whitening gel is applied on the teeth, which is then illuminated by an innocuous plasma light. The treatment is repeated as necessary. The result can be seen right after washing off and flushing. However with this smaller giving-up we can ensure our pleasant smile for quite a long-time!
