Teeth Whitening


Would you like to have a bright smile but your teeth are stained? Clinique St Charles Inc.  offers you its teeth whitening and dental cleaning in Longueuil and on the South Shore. Our state-of-the-art technology and safe enamel treatment products provide excellent results quickly.

Why Are My Teeth This Colour?

A brighter, whiter smile is the result of excellent dental hygiene and regular dental cleaning in Longueuil. It is well known that white teeth are the result of good tooth maintenance. It is important to know the reasons for tooth discoloration.

The causes of tooth discoloration are well known. They are frequently linked to our way of life. Poor dental hygiene, the consumption of sugary foods and certain drinks such as coffee or wine weaken the enamel and promote the appearance of stains. The nicotine found in tobacco, or some medicines containing iron, among others, also cause brownish and yellowish stains on your teeth. Factors such as age and genetics cannot be overlooked, they have an effect on the appearance and structure of teeth. It is important to know that discoloration does not only affect natural teeth, but also restorations made of resin.

What can I do? Opt for teeth whitening at our Longueuil clinic: it's the first step towards a smile you'll be proud of! Both before and after your treatment, we strongly advise you to adopt and maintain good oral hygiene habits, including regular visits to your dentist for a thorough cleaning.

How is the treatment going?

During your appointment with the dentist for teeth whitening in Longueuil, here are the different stages of the treatment:

  • The initial examination of the mouth and gum can detect any problems and determine the current state of your teeth.
  • Scaling: to get rid of bacteria and to eliminate plaques and tartars around the gum tissue and between your teeth.
  • Polishing: to remove any remaining stains on the surface of the teeth.
  • Application of a whitening gel and assessment of the color of the teeth after treatment.
  • Taking your oral impression for the manufacture of a custom-made splint.

You will also receive all the instructions and equipment necessary to extend the application at home for just a few days. This will give you the best out of your treatment and lasting results.

Does teeth whitening hurt?

Before performing dental treatment such as teeth whitening on a patient, our professional dentists perform a check-up to make sure that you do not have a hypersensitivity problem. In fact, we whiten when we are sure that your teeth are ready for treatment: we therefore make sure that you have no decay, periodontal disease or other condition opposing it and which could constitute a factor of risk.


During dental treatment, we pay special attention to your teeth in order to take the necessary measures in case of pain. There are no age limits for the elderly, however, you must be of legal age to be able to benefit from this treatment.

Consultation and Treatment: The Steps

We bleach when we are certain that your teeth are ready for the treatment, so we make sure you don't have cavities or any other conditions that might prevent them. Descaling and polishing always precede the application of the whitening gel. Once the treatment in the clinic is completed, you will be given mouth trays adapted to your teeth. You will also receive all the instructions and materials you need to extend the application at home for just a few days. You will get the best out of your treatment and long-lasting results.

Why is it safe and recommended?

Some patients may experience sensitivity when undergoing tooth whitening treatment. In Longueuil and on the South Shore, the staff at the Clinique Saint-Charles will reassure you: this feeling is only temporary. In fact, we use modern bleaching gels with added fluoride and potassium nitrate: your teeth are strengthened and will become even more resistant to sensitivity. There's no reason to hesitate: make an appointment today!
