Teeth whitening is a process of lightening the color of teeth. It is a bleaching process that reduces the discoloration of enamel and dentin caused by smoking, aging, consumption of tea, coffee and sodas. You can try tooth whitening if you have healthy teeth without any fillings. Teeth whiteners are not suitable for dark gray stains, crowns, colored fillings and stains due to some medications such as tetracycline. There are several types of products available for home use.
When selecting a whitener you must look for the ADA Seal for safety and efficacy. Teeth whitening gels or strips contain carbamide or hydrogen peroxide as the bleaching of the active ingredients. The whitening gel is placed in a thin bleaching tray that fits over the teeth. Teeth whitening strips are applied to teeth and gently press to make a contact between the whitener and the surface of the tooth. The results are usually seen in the first week.
You can experience tooth sensitivity to cold or discomfort in the gums during treatment. These symptoms always disappear within a couple of days after completion of treatment. Teeth whitening toothpastes help remove surface stain through the action of mild abrasives or chemical polishing agents. Whitening toothpaste with the Seal of Acceptance from the ADA program does not alter the intrinsic color of teeth, unlike the bleachers.
