Teeth Whitening At-Home

This page is focused on providing detailed instructions about AvA Orthodontics prescribed at home whitening for our patients. If you are seeking general information about teeth whitening, please see our treatment page.

Before starting your treatment 

  • Dental caries and leaking restorations are amongst the most common reasons for teeth to look dark. Whitening is not effective to change this type of discoloration. Rule out the presence of this possibility by consulting with your family dentist beforehand.  
  • Results vary from person to person, depending on the type of the stain, age, treatment time, frequency of use and concentration of the material and patient expectation. You may not achieve the exact bright color that you have in mind.  
  • Mild to moderate gum or tooth sensitivity is common after whitening and will go away after a few days. This sensitivity is generally related to the peroxide concentration of the material and the overall time in contact with the teeth. If the material is in contact with teeth for too long, it may cause irreversible sensitivity which requires your family dentist to intervene.
  • To be on the safe side, do not bleach your teeth during pregnancy or while nursing.
  • Gel material should never come in contact with your gum, skin or eyes at any time.
  • Whitening should be done before any cosmetic restoration on your teeth such as veneer or crowns. There is always a risk of existing restorations needing to be changed due to the color difference after treatment.
  • Your whitening kit contains three syringes of mint flavored gel, 22% carbamide peroxide.
  • Only use your custom whitening trays made at AvA Orthodontics. Using generic prefabricated trays are potentially dangerous for your gums and teeth. 
  • Do not use your clear retainers or Invisalign aligners as whitening trays.
  • Do not sleep with your trays on. It may cause irreversible damage to your teeth or your gums.  
  • Keep the unused gel in a refrigerator at all times.

  1. ​​Take an initial picture to monitor the progress and compare the before and after
