Teeth Whitening in Cornwall, Ontario
A brilliant first impression can feel out of reach when stains from food, tobacco, illness or medication dull your enamel. Professional teeth whitening at Cornwall Dental Arts — including the Zoom!® system — is a common, effective way to lift those stains and bring back brightness.
Treatment recommendations and outcomes vary based on your oral health, medical history and individual needs. A consultation is required to determine the most appropriate option for you.
How peroxide whitening works
Most whitening systems use a peroxide-based formula. When hydrogen peroxide breaks down, oxygen molecules reach deep into stain molecules on the tooth surface and help lighten them.
Store-bought kits work on a similar principle. The main difference with professional care is the peroxide strength we can safely provide — and the custom trays that hold the gel against your teeth for a more even result.
Take-home whitening with custom trays
We provide custom-shaped mouth trays and professionally prepared bleaching gel for you to use at home, at your convenience.
- Wear the trays as directed — often nightly during the initial phase
- The initial treatment run typically lasts about two weeks
- Afterward, you can use the same custom trays with gel refills for touch-ups and upkeep
This approach offers the convenience of at-home care with professionally effective strength. Patients from Cornwall, Long Sault, Morrisburg and Ingleside often choose take-home trays when they want flexible timing.
Zoom!® Teeth Whitening
Zoom!® is designed for busy schedules and is available as both an in-office and an at-home option at our Cornwall office.
| Zoom!® option | What to expect |
|---|---|
| In-office Zoom!® | Known for speed — teeth can look up to eight shades brighter in about one hour |
| At-home Zoom!® | A convenient path that can show about three shades of improvement in about three days |
During an in-office Zoom!® session, whitening gel containing hydrogen peroxide is applied to each tooth. A specialized light is then used to help the peroxide break down so oxygen can enter the tooth and lighten stains.
Results vary. Your starting shade, enamel and lifestyle habits all influence how bright your smile becomes and how long results last.
What whitening cannot change
Whitening products affect natural tooth enamel. They do not change the colour of:
- Crowns
- Veneers
- Bonding
- Bridges
- Tooth-coloured fillings
If you have visible dental work, we plan carefully so your smile stays balanced — sometimes whitening first, then matching new restorations later through cosmetic dentistry or veneers.
Sensitivity
Temporary tooth sensitivity can occur during or after whitening. Our team can recommend ways to improve comfort and determine whether whitening is appropriate for you.

Common questions
FAQ
Do you offer Zoom!® whitening?
Yes. Cornwall Dental Arts offers Zoom!® as both an in-office and an at-home whitening option.
How white will my teeth get with Zoom!®?
In-office Zoom!® can make teeth look up to eight shades brighter in about one hour. At-home Zoom!® can show about three shades of improvement in about three days. Individual results vary.
How long does take-home tray whitening take?
The initial treatment run typically lasts about two weeks when trays are used as directed. After that, custom trays and gel refills can support touch-ups and maintenance.
Will whitening make my teeth sensitive?
Some patients notice temporary sensitivity. It often settles within a short time. We can adjust the plan to help you stay comfortable.
Does whitening work on crowns or veneers?
No. Whitening gel changes natural enamel only. Existing dental work keeps its original shade.
Is professional whitening safer than drugstore kits?
Professional care begins with an oral health check and supervised use of whitening materials at higher peroxide strengths than typical store-bought kits. That oversight is one of the main advantages of treatment in a dental office.
