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 Teeth 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. Teeth 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 Teeth 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:
Teeth Whitening Toothpastes
All toothpastes help remove surface stain through the action of mild abrasives that scrub the teeth. Look for the ADA Seal for safe whitening toothpastes that have special chemical or polishing agents to provide additional stain removal effectiveness. Unlike bleaches, these types of ADA Accepted products do not change the color of teeth because they can only remove stains on the surface.
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 typically come in a gel and are placed in a tray that fits on your teeth. You may also use a whitening strip that sticks to your teeth. The concentration of the bleaching agent is lower than what your dentist would use in the office.
Are There Any Side Effects from Teeth Whitening?
Some people who use teeth whiteners may experience tooth sensitivity. That happens when the peroxide in the whitener gets through the enamel to the soft layer of dentin and irritates the nerve of your tooth. In most cases the sensitivity is temporary. You can delay treatment, then try again.
Overuse of whiteners can also damage the tooth enamel or gums, so be sure to follow directions and talk to your dentist.
