How does bleaching work?
Will whitening affect bond strength?
Will bleaching weaken the tooth’s enamel?
Do you think that the whitening is safe and effective and has certain restrictions;
Tooth whitening is the most simple, conservative, non-invasive therapy which can improve the color of the teeth of our patients. After thousands of clinical and laboratory research worldwide, we can now say that the bleaching is a safe and effective procedure. After long-term monitoring of patients found that there was no need for endodontic treatment, there was no internal or external resorption dental tissues, there was no tooth sensitivity beyond the normal range and generally no significant change in dental tissues occurs. Also, the growth of cancerous lesions were found in the language or other damage to the soft tissues of the mouth. They certainly stand provided use of materials, systems and techniques have been investigated both for safety and for their effectiveness. Since the decomposition of bleaching agents in the mouth the final resulting products water and oxygen.
Do you think that bleaching with the use of special light or laser systems are more efficient;
In general, we could say that the use of special light or laser systems during bleaching in the clinic is not necessary nor lead to better results. Worldwide, there are no statistically significant clinical findings demonstrate that the use of LED lighting (including laser) can improve or increase the bleaching effect.
Using illumination lamp during bleaching in practice causes dehydration of the teeth, giving a false picture and making the teeth appear whiter. The teeth will lose most of their brightness, and recover moisture at very short time. Finally, we must say that the use of light can create one heat of things in the teeth, increases the sensitivity of the teeth and if not done careful handling can cause permanent damage to the teeth.
How long can be the bleaching results and what bleaching agents;
Curing time of the whitening effect depends on the method that we follow but mainly by using colors that will make the patient after bleaching. Usually the whitening effect is maintained 1-3 years. More specifically, in a survey it found that the bleaching results are maintained at 90% the first year, 62% at 3 years and 35% at 7 years. The patients using bleaching splint have the important advantage that can make booster doses (one every 6 months or 1 per year for two days) and thus retain their color at a very good level for a longer period.
Regarding bleaching agents for bleaching in the clinic would recommend bleaching system with hydrogen peroxide and without use of the lamp, a light or thermal energy. For bleaching splints would recommend carbamide peroxide mainly 10% and sometimes 15%.
