Top Factors to Consider Before Getting Teeth Whitening in London Ontario

Teeth whitening is among the most popular cosmetic dental treatments in London, Ontario. Yet, the results can differ widely depending on your age, enamel thickness, oral health, and the type of stains you have.

This comprehensive guide explains the key factors that determine how effective your whitening will be, helping you make an informed and confident decision about your treatment.

1. Identify Your Type of Tooth Stains

Before starting, it’s important to understand what kind of discoloration you have.

Extrinsic Stains

These are surface stains caused by coffee, tea, wine, tobacco, or foods rich in pigments. They respond well to professional whitening treatments.

Intrinsic Stains

These occur beneath the enamel due to medication, ageing, or trauma. They are more resistant to whitening and may require multiple sessions or alternative solutions like veneers.

Tip: Ask your dental professional in London, Ontario to analyze your stain type using digital shade-matching tools. This ensures realistic expectations and the right treatment plan.

2. Evaluate Your Oral Health Condition

Whitening agents are effective only when your mouth is healthy. Any untreated cavities, gum inflammation, or plaque buildup can interfere with results and cause discomfort.

Pre-Whitening Checklist

• Schedule a professional cleaning.
• Treat any decay or gum problems.
• Check for existing restorations, since whitening does not affect crowns or fillings.

Why it matters: Whitening agents penetrate enamel. If your teeth or gums are already sensitive or damaged, you could experience irritation or uneven whitening.

3. Know Your Natural Tooth Shade

Each person has a unique enamel shade. Those with yellow undertones usually respond faster to whitening, while grey or brown tones require more gradual treatment.

Ask your dentist for a “before and after” shade comparison. This gives you a realistic sense of achievable results instead of expecting an unnaturally bright white.

4. Age and Enamel Thickness

As we age, enamel naturally thins, revealing the darker dentin underneath. This makes whitening slightly less effective in older adults.

For patients over 40, combining an in-office whitening session with at-home maintenance trays often yields better, longer-lasting results.

5. Choose the Right Whitening Method

Not all whitening methods are created equal. The right choice depends on your goals, budget, and sensitivity levels.

Method Description Ideal In-office whitening Fast results using high-strength peroxide under dental supervision Quick visible improvement: Dentist-supervised home kits Custom trays and controlled use over 1–2 weeks Gradual and even whitening Over-the-counter kits Store-bought strips or gels with mild agentsMinor touch-ups only

Insight: According to the Canadian Dental Association, dentist-supervised whitening remains the safest and most predictable approach due to controlled concentrations and professional oversight.

6. Understand Whitening Agents and Formulas

The active ingredient is what determines both the effectiveness and safety of whitening.

Most professional products use either hydrogen peroxide (3–10%) or carbamide peroxide (10–35%).

Ask your provider:

• What concentration is being used?
• How long will the agent stay on the teeth?
• Is there a desensitizing gel included afterward?

These questions ensure you avoid unnecessary sensitivity and protect your enamel.

7. Lifestyle Habits Affect Whitening Results

Daily habits strongly influence how long your results will last.

Avoid or limit:

• Coffee, tea, cola, and red wine
• Smoking or vaping
• Highly pigmented or acidic foods for 48 hours after treatment

Adopt:

• Drink water after consuming stain-causing beverages
• Brush twice daily with fluoride toothpaste
• Maintain regular professional cleanings every six months

In London Ontario’s colder months, increased tea and coffee intake can lead to quicker re-staining, so moderation is key.

8. Manage Sensitivity and Post-Whitening Care

Some temporary tooth sensitivity is normal after whitening.

To minimize discomfort:

• Use toothpaste for sensitive teeth containing potassium nitrate or fluoride.
• Avoid very hot or cold foods for two days.
• Follow all aftercare recommendations provided by your dentist.

Avoid DIY or online “home whitening” methods involving baking soda or charcoal. These are abrasive and not approved by Canadian dental authorities.

9. Consider Cost and Long-Term Value

Professional whitening costs more upfront but delivers more consistent, longer-lasting results.

In-office whitening typically lasts one to three years with good care. Over-the-counter options may fade within months, often requiring repeat applications.

Investing in professional whitening and maintaining results with periodic at-home touch-ups is the most cost-effective long-term strategy.

10. Ask the Right Questions Before You Begin

An informed consultation ensures the best outcome. Discuss the following with your dentist:

• What is my current and target tooth shade?
• How many sessions are required?
• What level of sensitivity should I expect?
• Will whitening affect my existing restorations?
• What post-whitening maintenance is recommended?

Clear answers will help you set expectations, avoid risks, and achieve a more predictable result.
