Benefits of Professional Teeth Whitening 

Safe Treatment

Professional treatments are safe and comfortable. Over-the-counter kits pose the risk of allergic reaction and damage to the enamel.

Easy Enhancement 

Teeth whitening can produce dramatic results with a minimal investment of time and money. Whiter teeth can take years off your appearance.

Consistently Bright Color

If you are receiving a veneer, crown, or other restoration on a tooth, bleaching them beforehand can provide consistently bright teeth to match.

"Consult a dentist, who can assess the cause of tooth discoloration and the best approach to achieving whiter teeth. If, after the consultation, the patient decides to proceed with tooth bleaching, the procedure should be performed under a dentist’s supervision and according to the manufacturer’s directions."
Canadian Dental Association

Drawbacks of Over-the-Counter Products

Over-the-counter whitening products have a few drawbacks compared to getting professional teeth whitening treatment at our office in Montreal, QC, including:

Slower or Limited Results

Whitening toothpastes, tray systems, and whitening strips with hydrogen peroxide can brighten smiles, but it can take weeks to see results. With a professional tooth whitening treatment at our Montreal, QC, clinic, patients can see noticeable results within an hour. 

No Professional Oversight

Patients using over-the-counter tooth whitening products may experience tooth sensitivity or sore gums if they overuse or misapply hydrogen peroxide or other bleaching treatments. With professional treatment, our dentists can assess issues with teeth, gums, or other areas of your mouth.

Teeth Whitening Procedure

Smile Montreal can offer different types of tooth whitening options to meet your needs and goals. For instant results, in-office whitening can lighten your teeth by up to eight shades in just one appointment. Take-home whitening treatments are an option for patients who wish to whiten their smile at their own convenience. 

In-Office Whitening

If you choose in-office whitening, we can provide a brighter smile in about an hour:

"In-office whitening can lighten your teeth by up to eight shades in just one appointment."
"In-office whitening can lighten your teeth by up to eight shades in just one appointment."

General Cleaning

 Before the whitening procedure, we will provide a dental cleaning to remove plaque and debris.

Gel Application

The dentist then applies a hydrogen peroxide-based formula to your teeth and activates it with an LED lamp. 

Repeated Applications

Depending on how darkly colored your enamel is, it can take one to three sessions for teeth to reach the desired shade of white. After each session (about 15 minutes long), we will remove and reapply the gel.



It is best to maintain your results by using a take-home touch-up kit or specialized toothpaste. Periodic re-treatments may also be necessary, depending on your goals.

Whitening at Home

Our Montreal practice also offers custom whitening kits designed for home use:

"Take-home whitening treatments are an option for patients that wish to whiten their smile at their own convenience."
"Take-home whitening treatments are an option for patients that wish to whiten their smile at their own convenience."


We will take impressions of your teeth and create a set of custom trays for your upper and lower arches. Unlike over-the-counter whitening products, custom trays ensure an exact fit that keeps the whitening agent from coming into contact with the gums and other soft tissues.

​Wearing Trays: 

Simply place the gel in the trays and wear them overnight or for several hours during the day, at your convenience.

Use Consistently:

By consistently wearing the trays every day, your teeth will gradually begin to lighten. The final results with take-home bleaching kits are achieved in two to three weeks.

Maintaining Your Results

The results are long-lasting, especially when compared to their drugstore counterparts. We will provide you with all the necessary tips and tools in order to maintain your results. These include:

Whitening Toothpaste

While these kinds of toothpaste are not usually effective in removing stains on their own, whitening toothpaste is great for maintaining the brightness of professional teeth whitening. 

Avoid Potential Stains

Darkly colored foods, beverages, and tobacco products all have the potential to stain your teeth. It is best to avoid them when possible. If you choose to drink sodas or coffee, do so with the aid of a straw to prevent the liquid from passing over the tooth enamel.
