Office parties, family dinners and Christmas Eve photos come up quickly. It’s often in November that we think: “I’d love a brighter smile for the holidays.” If you’re looking for teeth whitening in Repentigny, here’s how to choose between in-chair whitening and the take-home whitening offered at Centre dentaire Repentigny, and, most importantly, how to plan so you can get to December without the stress.
Teeth whitening, also called “dental bleaching,” aims to restore the whiteness your teeth once had. It’s a simple cosmetic treatment, but it is still dental care: it deserves a professional assessment and follow-up.
December is busy, for you and for appointment books. Here’s why it pays to start early:
In short: book your appointment a few weeks before your events rather than the day before.
At Centre dentaire Repentigny, in-chair whitening is done during an appointment of about an hour and a half. A dental hygienist applies the whitening treatment directly in the clinic. She also makes a custom tray that you take home to continue the treatment for a few days.
This option works well for people who:
For take-home whitening, our team makes custom trays and gives you the whitening product. For several days, you wear the trays during the day or at night, according to the instructions you receive.
This option may be a good fit if you:
This treatment requires more discipline from the patient: each step must be followed to achieve the desired result.
| Criterion | In-chair | At home |
|---|---|---|
| Where it starts | In the clinic, with a hygienist (about 1.5 hours) | At home, with custom trays |
| Follow-up | A tray is provided to continue for a few days | Trays worn for several days |
| Patient involvement | Moderate | Greater discipline |
There is no “best” option in absolute terms. Your starting shade, the sensitivity of your teeth, your restorations and your schedule guide the recommendation. Results vary from person to person; no one can promise a specific shade.
Strips and kits sold in pharmacies, big-box stores or online are tempting. Here’s how they differ from professional teeth whitening:
As our clinic page notes, in-clinic treatment is safe for the mouth and gums, unlike many products offered outside a professional setting.
An important point to know before whitening: the whitening product acts only on natural teeth. Crowns, white fillings (composites), bridges and veneers do not change colour during treatment.
So if you have a visible dental restoration at the front, it could show a shade difference with your natural teeth after whitening. That’s why it’s important to discuss it with your dentist before you start. In some cases, it may be better to plan the whitening before replacing a restoration, so a new shade can be chosen that will harmonize with your smile.

Whitening is not for everyone, or not right away. We generally recommend postponing it or talking with the dentist first if:
Only an exam can determine whether you are a good candidate.
According to our instructions, for 3 to 4 days after in-chair or at-home whitening — or 4 to 7 days during touch-ups — you should avoid eating or drinking coloured foods. Think coffee, tea, red wine, berries, soy sauce or tomato sauces. Choose foods without dark colourings. That’s the main reason not to have your whitening the day before a holiday dinner!
Sensitivity, especially to cold, is possible after treatment. Our instructions: brush with a toothpaste for sensitive teeth (such as Sensodyne Rapid Relief or Repair & Protect), then do not rinse, eat or drink for 30 minutes so the product stays in contact with the teeth. If the sensitivity persists, call us.
After either treatment, you can buy whitening gel tubes at the clinic during your cleaning appointment, to do your touch-ups with your trays.
Ideally a few weeks ahead, so you can have the exam and cleaning, complete the days of wearing the trays, and get through the period without coloured foods before your events.
The treatment is generally not painful, but sensitivity, especially to cold, can occur afterwards. A toothpaste for sensitive teeth often helps.
No. Restorations do not change colour. Talk to the dentist so you can plan the sequence of treatments.
We don’t publish fees online. The cost will be explained to you at the clinic, depending on the option you choose.
No. The response to whitening varies from person to person, depending on the starting shade and the type of stains.
