Any procedure that will give teeth a whiter appearance is called tooth bleaching or whitening. Bleaching products contain tooth bleaches like hydrogen peroxide and carbamide peroxide.

These bleaches disperse stains, making them less concentrated and enhancing the brightness of your teeth.

When teeth get yellow over time for a variety of causes, bleaching is frequently requested. Whitening can be accomplished by altering the intrinsic or extrinsic color of the enamel.

If you are interested in getting your teeth bleached, you have two options:

• In-Office Tooth Bleaching:
• In-office teeth beaching is performed by a dental professional. Your dentist can whiten your teeth so they get whiter more quickly and efficiently. Compared to DIY kits, the bleaching solution used by dentists is often harsher. Additionally, the whitening process may accelerate and intensify using heat, light, or a combination of the two.
• It often requires numerous 30- to 60-minute in-office visits to achieve the most dramatic effects, typically involving teeth being three to eight colors brighter. Some dentists employ procedures that may be finished in a single, two-hour visit.

• At-Home Tooth Bleaching:
• At-home bleaching techniques include:
• Strips and gels for teeth whitening:
• These peroxide-based tooth bleaching treatments are often applied once or twice daily for 10 to 14 days, straight to the teeth using a brush or a thin strip. Results persist for at least four months.
• Tray-based tooth bleaching:
• In this method for teeth whitening, a mouth guard-like tray is filled with a paste or gel that contains peroxide and is applied to the teeth for a few minutes to several hours each day for up to four weeks. You may get a custom-fitted tray-based teeth whitening device from your dentist or purchase one off the shelf.

Tooth sensitivity is a possibility for some persons who use teeth whitening products. This occurs when the peroxide in the bleaching agent penetrates the enamel to the delicate layer of dentin and irritates the tooth's nerve.

The sensitivity is often transient. Delaying therapy allows you to retry.
