Smile Direct Stain Barrier

New Stain Barrier prevents beverages from staining your teeth by creating an invisible shield that provides daily protection against beverages like coffee, tea, red wine, and soda. A single application protects your teeth for up 4 hours. And, it's enamel-safe and low-sensitivity, so it's ideal for everyday use. Apply it in the morning before coffee, at lunch before popping open that soda, then again after work as you get ready to relax with that glass of red wine. With 30 applications per pen, there's enough Stain Barrier gel to last for weeks. Stain Barrier even includes a gentle whitening agent that helps prevent any new stains from forming making it a perfect complement to any teeth whitening routine. To use, you simply brush a small droplet of Stain Barrier onto your teeth. The gel takes just 5-10 seconds to air-dry. For best results, we recommend waiting about 10 minutes before consuming beverages. It creates an invisible shield that prevents stains for up to 4 hours.
