Whitening treatments don’t permanently whiten teeth. If you expose your teeth to foods and beverages that cause staining you may see the whiteness start to fade in as little as 1 month after treatment. Those who avoid foods and beverages that stain may be able to wait one year or longer before another whitening treatment or touch-up is needed.
You worked hard to get your teeth white. Here are some tips to help maintain your pearly whites.
- Avoid the consumption of or exposure to products that stain your teeth, such as coffee, tea, and red wine. If you do choose to consume beverages that stain, consider using a straw so that the liquid bypasses your front teeth.
- Brush or rinse immediately after consuming stain-causing beverages or foods.
- Follow good oral hygiene practices. Brush your teeth at least twice daily, floss at least once daily to remove plaque, and rinse with an antiseptic mouthwash at least once a day to kill bacteria that cause plaque. Use a whitening toothpaste (once or twice a week only) to remove surface stains and prevent yellowing. Use a regular toothpaste the rest of the time.
- Consider touch-up treatments. Depending on the whitening method used, you may need a touch-up every 6 months or after a year or two. If you smoke or drink lots of stain-causing beverages, you may need a touch up more often.
