How Teeth whitening works with tray bleaching

Use of bleaching is suggested by Oral hygiene Specialists to whiten the natural tooth shade. It is a standard procedure in the cosmetic industry. One popular method for whitening teeth at home is professional tray bleaching. Tray whitening makes an excellent choice for those people who want to do things by themselves.

The technique of whitening teeth using tray systems was first introduced in the dental world in 1989. In the 1990’s, the method gained widespread acceptance by the dental community. As its popularity grew regarding acceptance from patients, manufacturers rushed to respond to the customer demands. The results of this rush created a whole range of at-home whitening products that are present in the stores today.

How it Works

To get started with custom-fitted tray systems, you first brush and floss your teeth. You then put a small amount of bleach solution into the top and bottom trays, then carefully insert the tooth trays into your mouth and wear the trays for an hour. After the required time, you remove the trays, rinse them under lukewarm water, dry them and store them for your next session.

Tray based systems have plastic bleaching trays that are made to fit over a patient’s upper and lower teeth. To perform the treatment, the patient places whitening gel in the trays and them seats them over their teeth. You then wear the for a prescribed period, in most cases multiple hours a day or even overnight. For a series of days or weeks, the effects if whitening process gradually takes place.

Most over-the-counter teeth bleaching tray systems come pre-filled with appropriate amounts of peroxide-based whitening gel. Most systems include a full of disposable trays, where you typically use two trays per day, one for your bottom side of the teeth and the other for your top teeth.
