A bright, white smile is often associated with confidence, good health, and positive first impressions. Over time, however, teeth naturally lose their brightness due to everyday habits, aging, and diet. This is where teeth whitening dental care plays an important role—offering a safe, effective, and professionally guided way to improve the appearance of your smile.
This comprehensive guide explains how teeth whitening works, why teeth become discolored, available treatment options, safety considerations, and what patients should know when seeking teeth whitening in London, Ontario.
What Is Teeth Whitening Dental Care?
Teeth whitening dental care refers to professional or dentist-supervised treatments designed to reduce stains and discoloration from natural teeth. These treatments use clinically approved whitening agents that penetrate the enamel safely while protecting gum tissue and tooth structure.
Unlike over-the-counter products, professional dental whitening focuses on:
- Enamel safety
- Even and natural-looking results
- Reduced tooth sensitivity
- Long-term oral health
Before whitening begins, dental professionals assess overall oral health, existing restorations, and sensitivity levels to ensure treatment is appropriate.
Why Do Teeth Become Discolored?
Understanding the cause of discoloration helps determine the most effective whitening approach.
Surface (Extrinsic) Stains
These stains form on the outer enamel and are commonly caused by:
- Coffee and tea
- Red wine
- Tobacco use
- Dark-colored foods
Deep (Intrinsic) Discoloration
These stains develop inside the tooth and may be caused by:
- Natural aging
- Certain medications
- Tooth trauma
- Excess fluoride exposure during childhood
Professional teeth whitening dental is designed to address both surface and deeper discoloration safely.
Teeth Whitening Options: Professional vs At-Home
Many people try at-home whitening products before considering professional care. While both options exist, the results and safety levels differ significantly.

Common options include:
- Whitening toothpaste
- Whitening strips or gels

Limitations include:
- Uneven whitening results

Benefits of Professional Teeth Whitening Dental Care
Choosing professional whitening comes with several advantages:
- Noticeable improvement in fewer sessions

- Safe enamel-friendly treatment
- Even natural-looking brightness
- Guidance on post-whitening maintenance
Professional dental care also ensures whitening does not interfere with existing treatments such as fillings or crowns.
Is Teeth Whitening Dental Care Safe?
When performed under professional supervision, teeth whitening dental care is considered safe for most adults. However, whitening may not be suitable for individuals with:
- Untreated cavities
- Active gum disease
- Severe tooth sensitivity
- Visible dental restorations
According to the Canadian Dental Association, professional teeth whitening performed under dental supervision is safe when proper guidelines are followed.
Health Canada also advises using dentist-approved products to reduce the risk of irritation or enamel damage.
A dental consultation helps determine whether whitening is appropriate for your oral health.
How Long Do Teeth Whitening Results Last?
Whitening results typically last between 6 months and 2 years, depending on:
