How Long does Teeth Whitening Last?

The longevity of teeth whitening results depends largely on the method used and your individual lifestyle habits. In general, professional whitening results can last anywhere from 6 months to 3 years.

Specific durations based on the treatment type include:

  • Professional In-Office Whitening: These high-concentration treatments typically last between 1 and 3 years when supported by proper maintenance.
  • Professional At-Home Gel Trays: These custom-fitted solutions generally provide brightness for 6 to 12 months with consistent use.

To extend the life of your results, dental professionals recommend several maintenance steps:

  • Avoid staining substances such as coffee, red wine, tobacco, and wild berries, especially in the first 48 hours after treatment.
  • Maintain a rigorous oral hygiene routine, including brushing twice daily and flossing.
  • Use whitening toothpastes approved by the Canadian Dental Association (CDA) for daily upkeep.
  • Schedule professional dental cleanings every six months to remove surface buildup.
  • Consider minor touch-up treatments every 6 to 12 months to sustain consistent brightness.
