Tray-Based Teeth Whitening Can Extend a Professional Whitening Treatment
Making Your Professional Teeth Whitening Treatment Last With A Tray-Based Teeth Whitening Treatment
Have you been wondering why your teeth change and become yellow looking? Tooth discoloration can be handled easily to brighten your smile. There are many reasons why our teeth change their color. Here are the main causes of tooth discoloration:
1. Heredity
2. Tea, cola, coffee, and wine
3. Excessive fluoride and use of abrasives
4. Tetracycline (antibiotic) staining
5. Old fillings
6. Aging
Toothpastes with whitening agents can reduce the yellow tinge that is on the surface of the teeth. This is what dentists call extrinsic staining. However, professional dental cleanings and whitening toothpastes will not change the intrinsic staining of the teeth, if used appropriately. This is the main reason why tooth bleaching or tooth whitening is so popular.
Normally, teeth whitening remedies are categorized into two:
1. Professional whitening systems
This is usually performed by dentists using whitening gels and lasers to activate the solution. This is normally done at your dentist’s office.
2. Home-based teeth whitening remedies
This could either be done in-between appointments of professional treatments using whitening kits and tray-based whitening techniques or are just home-made remedies from kitchen and medicine items. These applications are usually done at home and according to the frequency suggested by dentists and/or by a product’s instructions.
How is tray-based teeth whitening technique performed?
1. A teeth whitening gel is poured all over a tray that just fits over the teeth of the patient.
2. The active ingredient inside the gel, carbamide peroxide, will be broken down so that oxygen can enter
the enamel to bleach the discolored areas.
3. By this, the physical structure of each tooth is not actually changed. Crowns, fillings, and tooth bonding will not lighten but the colored substances will.
4. Casts or impressions of the tray are customized by dentists. The accuracy of the whitening trays is critical for the treatment.
