Put to the test

Fairlady - - PUT TO THE TEST -

STEP 4 Car­lene ap­plies bar­rier ma­te­rial over my gums to pro­tect them from the whiten­ing gel. A light hard­ens the bar­rier ma­te­rial.

STEP 5 She then uses a brush to ap­ply the gel to each tooth.

STEP 6 A ma­chine that emits light is in­ter­locked with the re­trac­tor to ac­ti­vate the gel.

The process is re­peated three times,and with each ses­sion, the gel bleaches your teeth lighter and lighter.
