Spray White 90 contains hydrogen peroxide. When applied to the teeth, =
hydrogen peroxide breaks down into water and Oxygen.=20
As the Oxygen molecules work their way through the dentinal tubules and =
into the tooth surfaces, they attach themselves to stain particles and =
effectively break the stains apart. With the stains removed, the teeth =
become whiter and brighter.
See your teeth whiter and brighter in 90 seconds.=20
