Tooth Bleaching is one of the best cosmetic procedures to get rid of yellow teeth that is very popular among office clients due to its reasonable cost, lack of tooth re-contouring, no damage to the teeth, and the possibility of its repetition.
Tooth bleaching can eliminate the damage caused by smoking, alcohol, coffee, medications, or trauma to the teeth.
Types of tooth bleaching
The main whitening agent for teeth is hydrogen peroxide(H۲O۲), which oxidizes the deposited pigments between the enamel pyramids and remove them. Over time, the material penetrates the lower parts of the enamel in the dentin, brightening its color and whitening the teeth. There are two general ways to whiten teeth with bleaching, which vary in the steps and cost of teeth bleaching.
Home bleaching: In this procedure, your dentist will mold your upper and lower jaws in one session, and the next session will give you a clearer pair. There is as much space between your teeth as much as your tooth needs to be whitened. In this session, you will be given the necessary material for bleaching at home.
Office Bleaching: In this procedure, the gums are protected using special materials.
Then, high concentrated bleaching materials are used on the teeth. The active ingredient of some of these substances is chemically activated, either by light or by heat. There is not much difference between them, and the cost of office bleaching is slightly different from the home bleaching.
Researchers believe that the best results are achieved when both methods are applied together. That means first performing office bleaching and then home bleaching. Consequently, office bleaching needs less time to yield results, but more lasting results are obtained by home bleaching.
Teeth whitening may vary from one degree to several degrees depending on the type of tooth and the type of pigment deposited between the teeth.
How long a tooth stays white depends on both the person’s diet and oral hygiene. Less use of colored foods and beverages helps keep teeth whiter for longer. In addition, bleaching is also a treatment that needs to be repeated from time to time to keep the tooth color white permanently.
The Reason for Tooth Discoloration
Teeth are made up of two parts, enamel, and dentin. The tooth enamel covers the dentin and makes the teeth clean and white. Enamel is thicker in some people, leading to clearer teeth. However, due to enamel erosion, the refraction of light decreases, and the color of the ivory becomes more visible over time. Moreover, some pigments penetrate into the pores of the enamel and bond to the enamel crystals, which causes a change in clearer color. Sometimes the pigments only settle on the enamel surface, causing black and brown spots on the tooth surfaces.
The most important causes of tooth discoloration are colored drinks such as tea, coffee, and smoking, increasing age, lack of proper oral hygiene. Avoiding any of the above and proper use of tea and coffee can be effective in keeping teeth white.
How to Prepare for tooth Bleaching?
Before bleaching, we need to repair decayed teeth. Bleaching has no effect on fillings, veneers, laminates, and yellow areas of the root caused by gingival-recession.
Before bleaching, dental scaling (if there is a plaque) and polishing will lead to better results.
Dental Bleaching Complications
Basically, bleaching does not have any side effects if it is done under the supervision of a dentist, it may only make the teeth sensitive for a while, which can usually be treated with anti-allergy toothpaste.
Whitening varnish and the other types of tooth whitening materials in pharmacies contain a much lower percentage of hydrogen peroxide. Therefore, teeth whitening may take more time. In addition, these materials are released in the mouth without any protection and there is no control over them, so they are washed and swallowed in salvia, which can also cause serious damage to the body. besides, these substances often contain saccharin, which although not harmful to teeth, but its carcinogenicity has long been proven.
