AfterZoom! is an in-office system for whitening natural teeth. It suits patients who want a visible change in one appointment rather than weeks of wearing trays, such as before a wedding, a new job or a family photo.
"They took great care of my teeth: the X-rays, cleaning, and whitening."
Liz, Google ReviewWhitening changes natural enamel only, so we look at what is causing your color before we recommend it.
Stain from dark drinks is the most common reason patients ask us about whitening.
The yellow cast teeth pick up over the years is what whitening lightens most reliably.
Brown stain from smoking often lightens well, though it returns sooner if the habit continues.
Gray banding from antibiotics taken in childhood resists light-activated whitening. KöR is often the better choice here.
Restorations keep their shade. We whiten first, then talk about matching any that show when you smile.
Decay and inflamed gums are cared for before whitening, so the gel only goes on healthy teeth.
One appointment, start to finish, with your new shade checked before you leave.
We examine your teeth and gums, ask what you want to change and record your starting shade.
Your lips and gums are covered so the gel touches only the tooth surfaces that will whiten.
The gel and the Zoom! lamp go to work while you relax in the chair.
We hold your new shade against the starting one and go over how to keep it.
"Dr. Nelly was so kind, professional, explained everything and put in process a plan for my teeth."

Straight answers to what patients ask us most before whitening.
Zoom! is a professional system applied by our dental team, not an over-the-counter kit. No drilling is involved, and the gel lightens stain without removing tooth structure. We confirm your teeth and gums are healthy before we begin.
It depends on the stain. Zoom! gives the fastest change in one visit for yellow and surface stain, while KöR is often the better fit for deep gray tetracycline stain. We recommend one after looking at your teeth.
Wear time depends on the strength of the gel. Some gels are made for short daytime wear and others for overnight use, so we tell you exactly how long to wear the trays with the gel we give you. Keep to that time rather than leaving trays in longer.
It varies with what you eat, drink and smoke. Coffee, tea, red wine and tobacco bring stain back sooner, while regular cleanings and take-home touch-ups help the shade hold.
Our Collegeville office is a short drive from Norristown. Zoom! is finished in one appointment, so treatment fits into a single trip.
Visit our office at 399 Arcola Road, Collegeville, PA 19426. We check your teeth, record your shade and plan the option that fits you.
