How Does Teeth Whitening Work?
Teeth whitening is a simple process. Whitening products contain one of two tooth bleaches (hydrogen peroxide or carbamide peroxide). These bleaches break stains into smaller pieces, which makes the color less concentrated and your teeth brighter.
Does Whitening Work on All Teeth?
No, which is why it’s important to talk to your dentist before deciding to whiten your teeth, as whiteners may not correct all types of discoloration. For example, yellow teeth will probably bleach well, brown teeth may not respond as well and teeth with gray tones may not bleach at all. Whitening will not work on caps, veneers, crowns or fillings. It also won’t be effective if your tooth discoloration is caused by medications or a tooth injury.
What Are My Whitening Options?
Talk to your dentist before starting. If you are a candidate, there are three ways to put the shine back in your smile:
Cleaning with Airflow
This is the diamond stain removal clean followed by a deluxe sparkle air flow polish. This state of the art treatment uses a fine air polishing powder to remove heavy stains. This option is great for people with sensitive teeth, heavy smokers and coffee and red wine drinkers
This procedure is called chairside bleaching and usually requires only one office visit. The dentist will apply either a protective gel to your gums or a rubber shield to protect your gums. Bleach is then applied to the teeth. A special light or laser might be used to enhance the action of the whitening agent.
Peroxide-containing whiteners actually bleach the tooth enamel. They come in a gel and are placed in a custom made tray that fits on your teeth. The concentration of the bleaching agent is lower than what your dentist would use in the office.
