Teeth whitening is a chemical bleaching process of the teeth. It refers to a non-invasive section of aesthetic dentistry. In the recent past, this type of method was only reserved for the rich and famous. Now, with technology being as advantageous as it is, you can get your teeth whitened through your Dentist Oahu for next to nothing (in most cases).
Dental discoloration can have different physiological or pathological causes. Among them are:
1. Inborn errors of color and transparency of dental tissues (hypoplasia, fluorosis, tetracycline use);
2. Age-related changes in color and transparency;
3. Changing the color and transparency as a result of caries;
4. Discoloration resulting in staining dentin pigments (coloring the naked dentin side of the oral cavity; staining dentin from the pulp chamber after endodontic treatment);
5. Surface staining of the teeth (pigments of food coloring, or the result of smoking, drug use, chlorhexidine, antibiotics, etc.);
6. Black plaque associated with the presence of certain microorganisms in the oral cavity;
7. The presence of tartar;
8. Injury of the teeth.
Bleaching performance largely depends on the cause of the discoloration. Whitening involves breaking down the color of which is associated with surface staining, age-related changes, etc. This is done by staining the dentin. Among the contraindications are inborn errors of bleaching, high transparency of hard tissues, staining the exposed dentin from the oral cavity. Naturally, your local Dentist Oahu cannot bleach teeth that have artificial crowns, filling material and the like. Visit website for complete details.
All whitening techniques are based on the initiation of catalytic and photo-catalytic isolating peroxide compounds, bleaching agents and oxygen. Oxygen penetrates the dentin (dentinal tubules) and enters into the oxidative cleavage of the pigments. In most cases, the bleaching agents include carbamide peroxide (urea peroxide), which upon contact with water forms hydrogen peroxide. The decay process is accelerated by the action of chemical catalysts (e.g., bleaching systems) or (in the case of light-absorbing compounds) optical radiation.
Since whitening has become such a force to be reckoned with in the past few years, more dentists are using new techniques. You can find out what these are by contacting your local dentist. For more information call Dr. Garrett T. Hayashi DDS today.
