Application: \tBrush and floss teeth. \tPlace a small amount of whitening solution into tray. \tPlace the tray in your mouth carefully, making sure that it is seated all the way. \tRemove any excess gel from the gum tissue with your finger or dry toothbrush. \tFor 35%: \tKeep the tray in your mouth for 30-60 minutes. \tAfter 30-60 minutes, remove and clean the trays with cold water. \tFor 15%: \tKeep the tray in your mouth for 4-6 hours \tAfter 4-6 hours, remove and clean the trays with cold water. \tPlace a small amount of fluoride in trays (Prevident Gel). \tPlace trays in mouth for 5 minutes.Do not swallow fluoride, spit out any excess. \tRemove and clean trays. \tStore your whitening trays in their case, away from children and pets. Some Tips For The Most Successful Results. \tAvoid tobacco, coffee, colas and red wines. They contain heavy staining substances, which can prevent optimal whitening. \tRefrain from citrus fruit, citrus fruit juices, soft drinks and antacids.These may change saliva acids and slow down the whitening process. \tDo not eat or drink while your whitening trays are in. \tPostpone whitening if pregnant or nursing. What you can expect: \tAreas closest to the gum tissue may take longer to whiten then the rest of the tooth. \tYou may experience some mild sensitivity during treatment.If this occurs, discontinue use until sensitivity is completely gone. Then continue as directed. \tSome of our patients have found they like to re-brighten their smiles after 4 to 6 months by wearing their whitening trays for a night or two.This will keep your smile bright and beautiful. \tIf gums turn white and are sensitive while whitening, remove the excess gel from the area and replace the trays.
