Teeth can become darker over time, and sometimes even regular brushing and flossing can’t prevent this. Coffee, tea, red wine, and tobacco, which are parts of many people’s daily routines, contribute to this darkening. Add certain medications and natural aging to this list. Professional teeth whitening is the solution that offers an effective way to remove many of these stains and brighten your teeth once again. At our clinic, Dental North York, we provide professional teeth whitening treatments for our patients. Of course, an examination of your teeth and gums comes first. This is to determine whether whitening is appropriate for you, and which option is likely to produce the best result. Appointments are available for patients throughout North York and the surrounding Toronto area.

How Professional Teeth Whitening Works

During a professional teeth whitening session, we use peroxide-based whitening agents that penetrate the enamel and break down stain molecules inside the tooth structure. Unlike whitening toothpastes, which mainly remove surface stains, professional treatments can lighten the underlying colour of your teeth. The whole process typically includes:
  • An examination to confirm whitening is suitable for you
  • Assessment of existing restorations and tooth colour
  • Application of professional whitening gel
  • Monitoring throughout treatment
  • Post-treatment instructions to help you maintain results

What Happens During Your In-Office Appointment

If your choice is an in-office treatment, you might want to know what happens during your appointment:

1. Oral Examination

Our dentist examines your teeth and gums and discusses your whitening goals. We review existing restorations and sensitivity concerns before treatment begins.

2. Shade Assessment

We record the current colour of your teeth. This provides us with a baseline for evaluating the whitening result.

3. Protection of Soft Tissues

Our dentist places protective materials around your gums and soft tissues to limit contact with the whitening gel.

4. Whitening Application

The whitening gel is applied to your visible tooth surfaces. Depending on the system being used, we may refresh the gel during your appointment.

5. Final Evaluation

When the treatment is complete, we remove the gel and assess the new tooth shade. Our dentist will provide you with home-care instructions before you leave.

What Causes Teeth to Stain or Discolour?

Several factors contribute to tooth discolouration:
  • Coffee and tea: Dark pigments can gradually stain enamel.
  • Red wine: Contains colour compounds that can adhere to tooth surfaces.
  • Tobacco use: Nicotine and tar are common causes of yellow and brown staining.
  • Aging: Enamel naturally becomes thinner over time, which makes underlying dentin more visible.
  • Certain medications: Some antibiotics, such as tetracycline and doxycycline, may affect tooth colour when they are taken during tooth development.
  • Poor oral hygiene: Leads to plaque and tartar accumulation, and makes teeth appear darker.
  • Trauma to a tooth: An injured tooth may become grey, yellow, or darker over time due to changes within the tooth’s nerve and blood supply.
  • Highly pigmented foods: Berries, curry, tomato-based sauces, and soy sauce contain strong pigments that may contribute to tooth staining over time.

Who Gets the Best Results from Whitening Treatments?

Professional whitening is often most effective for natural teeth with yellow or light brown staining. Results may vary for different patients, but you may be a good candidate if you:
  • Have healthy teeth and gums
  • Have staining caused by food, beverages, tobacco, or aging
  • Have realistic expectations about whitening results
  • Do not have untreated cavities
  • Do not have active gum disease
  • Would like a lighter tooth shade without restorative treatment

Teeth Whitening Costs in North York

The cost of teeth whitening depends on the treatment method you select and the complexity of your case. In-office whitening is generally more expensive than take-home systems because you receive the treatment under direct professional supervision, and stronger whitening agents are used for you.

How much does professional teeth whitening cost?

The costs vary between different clinics and treatment systems, but as a general estimate, teeth whitening in North York can cost between $250 to $450 per session. We recommend booking a consultation, since it provides the most accurate pricing information.

Is in-office whitening more expensive than take-home whitening?

In most cases, yes. The reason is that in-office treatment involves clinical supervision and stronger whitening materials.

Are touch-up teeth whitening treatments available?

Yes, they are. Some of our patients choose occasional touch-up treatments to maintain their results over time.

Questions Patients Ask About Teeth Whitening

No. Whitening products do not change the colour of crowns, veneers, composite bonding, or tooth-coloured fillings. If you have existing restorations, they may appear darker if the surrounding natural teeth become lighter.

We notice a modest improvement for some of our patients, while others achieve several shades of lightning. By the way, the improvement is definitely noticeable.

Most dental insurance plans in Ontario classify teeth whitening as a cosmetic procedure and do not cover it. However, coverage details vary by provider and policy. You’d better confirm benefits directly with your insurer.

Some patients experience temporary sensitivity during or shortly after whitening treatment. This typically improves within a few days.

Your whitening results may last from several months to a few years, depending on your diet, tobacco use, oral hygiene habits, and performing touch-up treatments.

A professional cleaning before whitening is beneficial because it removes plaque and tartar that can affect the final result.

We generally recommend addressing untreated cavities and active gum disease before whitening treatment.

We recommend avoiding strongly coloured foods and beverages for the first 24 to 48 hours after treatment. We will provide specific instructions after your appointment.
