Teeth whitening (or teeth bleaching) is the process of lightening the color of the natural tooth enamel. It is generally accomplished using bleaching products which contain hydrogen peroxide to oxidize the chromogens that cause discoloration. This is usually done in the dentist’s office, but over-the-counter systems are available to the public for home use. This is not a permanent solution to staining and the whiteness will fade over time due to continued exposure to food and beverages that stain.
The most common side effects are temporary increased tooth sensitivity and irritation of the soft tissues, particularly the gums. The sensitivity is due to the initial bleaching action and will resolve once the whitening treatment has been completed. The tissue irritation is usually caused by a poorly fitting mouthpiece tray and can also be relieved by adjusting the tray fit or discontinuing the whitening product.
Teeth Whitening: Get a Brighter Smile with These Tips
To keep your smile bright and healthy, brush twice daily, floss once a day, and rinse with an antiseptic mouthwash at least once a day. Avoid foods and beverages that stain, including red wine, dark sodas, coffee, berries, and certain sauces. If you must eat them, try to do so sparingly or with a straw and use a fluoride toothpaste.
Be cautious of home whitening methods promoted on the Internet that suggest utilizing cooking oils, apple cider vinegar, activated charcoal, or other kitchen staples to whiten the teeth. These unproven and potentially dangerous methods can damage the teeth and are not recommended by dental professionals.
