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.
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:
A common question for patients seeking teeth whitening is the difference between in-office whitening and take-home kits. Let’s have a quick comparison:
| In-office Whitening | Take-Home Whitening Kits |
| Performed under dental supervision | Used at home according to the instructions |
| Higher concentration whitening agents | Lower concentration whitening agents |
| Results often visible after a single visit | Results develop gradually after several days |
| Suitable for patients seeking faster results | Suitable for patients who can tolerate a slower process |
If your choice is an in-office treatment, you might want to know what happens during your appointment:
Our dentist examines your teeth and gums and discusses your whitening goals. We review existing restorations and sensitivity concerns before treatment begins.
We record the current colour of your teeth. This provides us with a baseline for evaluating the whitening result.
Our dentist places protective materials around your gums and soft tissues to limit contact with the whitening gel.
The whitening gel is applied to your visible tooth surfaces. Depending on the system being used, we may refresh the gel during your appointment.
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.
Several factors contribute to tooth discolouration:
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:
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.
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.
In most cases, yes. The reason is that in-office treatment involves clinical supervision and stronger whitening materials.
Yes, they are. Some of our patients choose occasional touch-up treatments to maintain their results over time.
If you are considering teeth whitening, you should first know if it is appropriate for your teeth and gums. During the visit, our dentist will discuss expected results and any factors that may affect the outcome. At Dental North York, we provide both professional whitening consultations and treatment appointments for patients across North York and Toronto.
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.
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.
We always take care of your smile
