Tray-based teeth whitening

What is the Tray-based teeth whitening?

Tray based teeth whitening (Teeth whitening using teeth whitening trays) treatments can provide the ideal home whitening solution, depending on the level of tooth discoloration.

The trays are tailored to fit the exact contours of your teeth and are specially moulded to fit into your mouth like a gum-shield. This allows the home teeth whitening gel to closely contact your enamel to produce an all over, consistent, whiter smile.

What is the procedure?

Duration of the treatment depends on the amount of whitening you require - some teeth lighten after a few days. Maximum results generally occur when the process is continued for approximately 2 weeks. Some patients may require longer to achieve the desired result.

A dentist usually provides with first treatment and informs how to use the trays at home. Once teeth whitening treatment started, the procedure should be continued at home. This means regularly applying the whitening product over several days for between 60 and 90 minutes per day. By applying a small amount of the gel to the specialized tray and fitting the tray onto teeth, the home whitening system will remove most stains.

What kind of result can you expect?

Tooth whitening (bleaching) gel will only whiten natural teeth. It will not bleach (whiten), nor harm bonding, caps, crowns, bridges, fillings or any other artificial dental work.

Patient may have to have the dentistry redone in order to match new white teeth.

Recovery period and recommendations

Possible side effects and complications

During the first 3-4 days following bleaching, many patients experience sensitivity. This sensitivity is usually mild if teeth are normally sensitive.

It may be necessary to reduce the number of hours you wear the bleaching tray or stop using it for a short time to resolve the sensitivity. If teeth are normally sensitive, bleaching may make teeth much more sensitive for an extended period of time.

Under these circumstances, patient may choose to delay bleaching until he is able to complete desensitization procedures.

Tetracycline (an antibiotic) stained teeth or grayish teeth are more difficult to bleach and have a varied prognosis.

Exposed root portion of teeth which occurs with gum recession will also not bleach. If the patient has amalgam (silver) fillings in, near or behind the front teeth, long term bleaching can cause the surrounding tooth to have a greenish tinge.

Bleaching teeth which have a lot of translucency can cause the teeth to become even more translucent and may give the tooth a darker appearance.
