IN-Office: The Zoom!® In-Office whitening system will make your teeth dramatically whiter in just one appointment. The procedure is simple. It begins with a short preparation to cover your lips and gums, leaving only your teeth exposed. The Zoom! provider then applies the Zoom! whitening gel which works in coordination with an LED lamp to accelerate results. The combination of gel and light work together to gently penetrate your teeth, breaking up stains and discolouration. With proper care, your smile will sparkle for years. Our in-office treatment includes custom fit trays and touch up gel for at home maintenance.
