- Teeth with multiple colorations, bands,
splotches or spots due to tetracycline use
or uorosis do not whiten as well, may
whiten unevenly, and may require additional
whitening treatments.
- Previous orthodontic treatments may
cause teeth to whiten unevenly either due
to residual resin remaining on the teeth or
overpolishing upon removal.
- Crowns and other tooth-colored restorations
will not whiten.
- Tooth-colored restorations may require
replacement following whitening to maintain
a uniform color.
Pre-treatment for reducing tooth
sensitivity
It is recommended to prescribe the following
prior to the treatment:
- Treat with a desensitizing toothpaste with
5 % KNO
3
twice a day for 14 days before the
procedure
- NSAID adhering to the respective drug’s
instructions for use 1 hour before the
procedure
Warnings
- Do not place a composite/bonded
restoration within seven days after whitening
treatment to ensure color stability of the
composite/bonded restoration and bond
strength to enamel and dentin.
- Do not use tooth whitening gel on
anesthetized teeth.
- Tooth whitening is not recommended when
there are previous injuries in the gingival
tissues.
- Avoid contact of whitening gel with eyes and
soft tissue. If contact with eyes occurs, rinse
eyes immediately with plenty of water and
seek medical advice.
