Coffee, tea, red wine and time all leave their mark on enamel. Professional whitening at Peridot Dental Care lifts those stains safely, with gel strengths and custom trays you simply cannot buy at the pharmacy.
Professional teeth whitening uses dentist-supervised peroxide gel to break down stains inside the enamel. At Peridot Dental Care in Woodbridge you can choose a one-visit in-office treatment or custom take-home trays. Most people see several shades of improvement, and results last six months to two years.
Stains are not a sign of poor hygiene on their own. Even people who brush well notice their teeth darken over the years. Understanding the type of stain helps us choose the right treatment, and tells you what results to expect.
Caused by coffee, tea, red wine, curry, berries and smoking. These respond very well to whitening and to a polish during your hygiene cleaning.
Enamel thins with age, letting the yellower layer underneath show through. Whitening usually brightens these teeth noticeably.
Some medications, trauma or a dead nerve cause internal discolouration. These may need veneers, bonding or root canal care.
Both options use professional-strength gel and both are planned after an exam. The difference is speed and convenience.
We confirm your teeth and gums are healthy, note your starting shade and talk about your goal.
A professional cleaning removes plaque and surface stain so the gel reaches the enamel evenly.
Gel is applied in timed rounds while your lips and gums are protected. You can relax, listen to music or watch TV.
We record the new shade, share a short white-diet list for 48 hours and fit trays for touch-ups if needed.

Thinking about a bigger change? Whitening is often the first step in a cosmetic dentistry plan, followed by bonding or veneers to fix shape or chips.
Crowns, veneers and fillings do not change colour with whitening. If you have visible restorations, we will plan the timing so everything matches. You can read more in how to prevent stains on new porcelain crowns.
Patients visit us from Woodbridge, Vaughan, Kleinburg, Maple, Concord and Bolton.
Whitening works best for people with healthy teeth and gums whose main concern is overall colour. Before we start, we check for cavities, cracked teeth, worn enamel near the gumline and receding gums, because gel can make these areas sensitive. If any of these are present, we treat them first so whitening is comfortable and safe.
We will also be honest about expectations. Teeth naturally have some variation in colour, and the aim is a bright, healthy shade that suits your face rather than an unnatural, flat white.
Planning for a wedding, graduation or big presentation? Book your consultation about four to six weeks ahead. That leaves time for a cleaning, any small fillings, whitening and a buffer for touch-ups. If you are also considering bonding or veneers, whitening has to come first, and the colour needs about two weeks to settle before shade matching. Tell us your date and we will map out the timing for you.
Results usually last from six months to two years. They last longest when you limit coffee, tea, red wine and smoking, keep up with cleanings and use occasional take-home touch-ups.
Yes, when it is done or supervised by a dental professional after an exam. We check for cavities, gum problems and worn enamel first and protect your gums during in-office treatment.
Some people feel temporary sensitivity for a day or two. Using a sensitivity toothpaste for two weeks before and after, and adjusting how long trays are worn, keeps most patients comfortable.
In-office whitening gives the fastest change in a single visit. Custom take-home trays whiten more gradually over one to two weeks and are great for touch-ups. Many patients combine both.
No. Whitening gel only changes natural enamel. If you have front crowns, veneers or bonding, whiten first and then match or replace the restorations to your new shade.
Most people see a noticeable change of several shades. Yellow-toned stains respond best, while grey stains from medication or trauma may need bonding or veneers instead.
Whitening is not recommended during pregnancy or breastfeeding, for children with developing teeth, or for people with untreated decay or gum disease until those are treated.
