Calgary Teeth Whitening Dentist
Choose professional in-office or take-home whitening for a brighter smile
Dr. Janet Kan will examine your teeth, discuss your goals and help you choose an option based on your timeline, sensitivity and the type of discolouration you have.
Professional teeth whitening with realistic expectations
Teeth whitening can brighten stains caused by coffee, tea, red wine, tobacco and normal changes over time. However, it does not work equally well for every tooth or every type of discolouration.
Before recommending treatment, Dr. Kan will look at:
- What is causing the discolouration
- Whether your teeth and gums are healthy enough for whitening
- Whether you have fillings, crowns, or veneers that will not change colour
- How sensitive your teeth are
- How quickly do you want to see results
- What level of brightness may be realistic for your smile
What teeth whitening options are available?
Rideau Dental on 4th Street offers LumiBrite whitening in two formats.
LumiBrite in-office whitening
In-office whitening is designed for patients who want a brighter smile in a shorter amount of time.
The whitening treatment is completed in our Calgary dental office under professional supervision. Dr. Kan and the team protect your gums, apply the whitening product and monitor your comfort throughout the appointment.
- Want noticeable results more quickly
- Prefer to complete treatment in one dental visit
- Have an event or deadline approaching
- Want the process supervised by a dental professional
- Do not want to manage daily whitening applications at home
LumiBrite take-home whitening
Take-home whitening allows you to brighten your teeth gradually on your own schedule.
Our team will explain how to use the whitening system, how long to wear it and what to do if you experience sensitivity. Because treatment happens over time, you have more control over the pace and final shade.
- Prefer gradual results
- Want to whiten around your own schedule
- Would like more control over the pace of treatment
- Have concerns about sensitivity
- Want an option you can use at home with professional guidance
Start with a whitening consultation
A consultation helps determine whether professional whitening is likely to give you the result you want.
During your visit, Dr. Kan will:
- Examine your teeth and gums
- Identify the likely cause of the discolouration
- Review your dental restorations
- Ask about previous sensitivity
- Discuss your preferred timeline
- Compare in-office and take-home whitening
- Explain the results you may realistically expect
- Review the cost before treatment begins
What kinds of stains can
teeth whitening improve?
Professional whitening works best on natural tooth enamel affected by common surface and age-related stains.
Food and drink stains
Coffee, tea, red wine, cola and darkly coloured foods can gradually stain the enamel.
Tobacco staining
Smoking and other tobacco products may cause yellow or brown discolouration. Whitening may help, although the result depends on the severity and depth of the staining.
Natural changes over time
Teeth commonly appear darker or more yellow with age as the enamel becomes thinner and the underlying tooth colour becomes more visible.
General yellowing
Teeth with a yellow tone often respond more predictably to whitening than teeth with grey, brown or internally caused discolouration.
What teeth whitening cannot change
Whitening treatment only changes the colour of natural tooth structure.
- Dental crowns
- Veneers
- Bonding
- Tooth-coloured fillings
- Bridges
- Dental implants
- Dentures
If you have restorations in visible areas, they may look darker than your natural teeth after whitening. Dr. Kan will help you understand whether this is likely to affect your final result.
- Discolouration caused by tooth trauma
- Certain medication-related stains
- Developmental enamel changes
- Severe internal staining
- A single tooth that has darkened after injury or root canal treatment
In these cases, another cosmetic or restorative option may be more suitable.
Is professional teeth whitening right for you?
You may be a candidate for whitening if:
- Your teeth and gums are generally healthy
- You have yellowing or surface stains
- You want to brighten your natural teeth
- You understand that restorations will not change colour
- You have realistic expectations about the result
- Any active dental problems have been addressed first

Will teeth whitening
cause sensitivity?
Some patients experience temporary tooth sensitivity during or after whitening. Others notice little or no discomfort.
Sensitivity may be more likely if you:
- Already have sensitive teeth
- Have exposed tooth roots
- Use whitening products too frequently
- Wear take-home whitening for longer than directed
- Have untreated cavities or enamel damage
Contact our office if sensitivity is severe, persistent or accompanied by pain in a specific tooth.
How white will your teeth get?
Whitening results vary from person to person. No dentist can guarantee an exact final shade before treatment.
Your result will depend on:
- Your natural tooth colour
- The cause and depth of the stains
- Your age
- Your enamel
- Previous dental treatment
- The whitening option selected
- How your teeth respond to the product
- Your habits after treatment
