Lightening a darkened tooth

  • Clean all your teeth thoroughly.
  • Your dentist will make an access cavity and seal over the root filling so we can whiten inside the tooth.
  • Clean out the cavity within the tooth with a small brush and use water in the syringe to irrigate; this will clear any food debris. Also, brush the outside of the teeth/tooth and floss as normal.
  • Dry the inside of the cavity with a cotton bud.

Preparing the tray for whitening

  • Using 10% gel, fill the whole tray if you are whitening all the teeth at once, or if you are concentrating on the darkened tooth, fill just the reservoir relating to that tooth.
  • Place the gel syringe at the bottom of the cavity within the tooth and fill it with gel. Then, place the prepared tray straight over your teeth.

You may need someone to help you the first few times, as it can be tricky to see what is happening. You can whiten more frequently daily for 2/3 hours at a time, as the darkened tooth has no nerve.
