Whitening treatments do not 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.
  • 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.
  • 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.
