Teeth Whitening Myth - Once Whitened, My Teeth Will Stay White Forever!
Unfortunately this is not true! The effects of your lifestyle will have an impact on how quickly and how much your teeth will stain again. Eating fruits and vegetables, drinking red wine, coffees, dark sodas, tea and smoking will cause your teeth to stain your teeth more quickly than going without these foods.
But it isn’t all bad news; it is unlikely that your teeth will stain back to the point where they were before your treatment. And, to help counteract the fact that your teeth will stain again, we recommend having your teeth whitened every 3 to 6 months so you can keep your pearly whites. In the meantime, try drinking those staining liquids through a straw and by rinsing your mouth with water after every meal will help keep those pesky stains away.
