How long will the whitening last?

It is normal to get a little regression in the first 2 weeks after whitening as the whitening bubbles exit the tooth. From here typically the results can last one to four years, depending on the amount of staining beverages like wine, tea and coffee that the teeth are exposed to over time. Long term people can get reabsorption of stain molecules. If you enjoy your coffee tea and red wine we suggest a periodic maintenance programme.
