how long do teeth whitening strips last

The effects of teeth whitening strips typically last anywhere from several months to a year, depending on various factors. These include your diet, oral hygiene habits, and whether you smoke. Consuming stain-causing foods and drinks (like coffee, tea, red wine, and berries) frequently can shorten the duration of your whitening results.

To prolong the effects, maintain excellent oral hygiene, attend regular dental check-ups, and consider occasional touch-up treatments as recommended by your dentist or the product instructions. Always consult your dentist for personalized advice on maintaining your whitened smile safely and effectively.
