Tooth discoloration should not be taken lightly though the case should really lighten to brighten up a smile. There are many reasons why teeth get stained. The most typical reasons vary from factors written below:

  1. heredity
  2. consumption of staining substances (such as tea, coffee, and colas)
  3. excessive fluoride and use of abrasives (which only expose dentin and causes severe discoloration)*
  4. tetracycline (antibiotic) staining
  5. old fillings
  6. aging

Toothpastes that have whitening agents can minimize the stain that is on the surface of the teeth. The case is also coined by dentists as 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 inside a dental clinic.
  2. Home-based teeth whitening remedy

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.

Just how is tray-based teeth whitening technique employed to the patient? Read on the following four-step procedure:

  1. A 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 sp that oxygen can enter the enamel to bleach the discolored areas.
  3. By this, the physical structure of each tooth is not actually transformed. Crowns, fillings, and Bonding will not lighten but the colored substances will.
  4. Casts or impressions of the tray are customized by dentists. The accuracy of the trays is critical to the treatment.
