Teeth Whitening Instructions

  • In addition to your whitening trays, the whitening kit you have been given includes whitening gel, sensitivity solution, and instructions.
  • To achieve the best results, brush your teeth and floss before whitening.
  • After brushing and flossing, dry your teeth by swallowing well and wiping any excess saliva off your teeth.
  • Express a small amount of whitening gel into the front side of the whitening tray for every tooth you want to whiten (often not the farthest back teeth). Place the trays into your mouth. If you notice a significant amount of gel squeeze out of the trays, you’ve placed too much whitening gel into them. Gently wipe away the excess and be sure to use less next time. You’ll quickly learn the correct amount to use.
  • Allow the trays to remain seated against the teeth for at least 30 minutes. After removing the whitening trays, rinse your mouth with lukewarm water. Cold or hot water may be slightly uncomfortable to the rinse with at that time. Then brush your teeth with warm water and rinse your trays with cold water. If your teeth are not sensitive, you can repeat this step and do two applications of whitening gel back to back for quicker results. Another option is to wear the trays overnight while sleeping. Just be sure to brush your teeth with warm water and rinse your trays with cold water in the morning.
  • You may expect some slight gum sensitivity from wearing the whitening trays and your teeth may feel temperature sensitive as well. If you feel more than slight sensitivity or continuous sensitivity of the teeth or gums after whitening, please contact the office.
  • Make sure to follow the Kor instructions provided with your whitening kit to address and prevent excess sensitivity. If the Kor desensitizer is not effective, please let us know. There are other desensitizing products we can recommend to wear in your tray following a round of whitening to help ease the discomfort.
  • Please remember that everyone’s teeth will whiten at different rates depending on the original color and type of stain present. Not to mention, different people absorb the whitening gel at different rates. Some peoples’ teeth respond very well, while others are more resistant to whitening. We will check your teeth in about two weeks to see how you are progressing and at that time will make any necessary changes to get you the best results possible.
  • During the two weeks of at-home whitening, stay away from staining foods and drinks. You do not want stain to reduce the success of whitening. If possible, when drinking a staining beverage, keep the beverage off the outer surface of the teeth by drinking through a straw.
  • Smoking should also be held to the very minimum during the whitening process.
