What Is Professional Teeth Whitening?

Professional teeth whitening is a safe, clinically proven cosmetic dental treatment that removes deep stains and discolouration from the enamel and dentine of your teeth. Unlike store-bought strips or whitening toothpastes, our dentist-applied treatments use professional-strength whitening agents and custom-fitted trays to achieve consistent, lasting results.

At Dentistry on Guelph, our teeth whitening treatments:

• Lighten teeth by several shades in a single visit
• Use professional-grade, dentist-supervised whitening
• Are tailored to your sensitivity level and smile goals
• Provide longer-lasting results than OTC products
• Are performed or supervised by a licensed Guelph dentist

Types of Professional Teeth Whitening in Guelph

In-Office Teeth Whitening

Our most popular option. A concentrated whitening gel is applied chairside and activated with a professional light. Results are visible immediately — teeth can brighten by up to 8 shades in a single 60–90 minute appointment.

Benefits:

• Fastest, most dramatic results
• Comfortable, dentist-supervised session
• Ideal for special occasions or a quick refresh

Take-Home Whitening Kits

Custom-made whitening trays fitted to your teeth paired with a professional-strength whitening gel — the same active ingredients used in-office, in a convenient at-home format. Results develop gradually over about 1 to 3 weeks of consistent use.

Benefits:

• Flexible — whiten on your own schedule
• Custom trays for even coverage and less sensitivity
• Easy to use for ongoing maintenance

Combination Whitening

Get the best of both worlds. Begin with an in-office session for immediate brightening, then continue at home with your custom trays to deepen and maintain your results over time.

Benefits:

• Maximum whitening potential
• Longer-lasting results
• Great value for comprehensive whitening

Is Professional Whitening Right for You?

Whitening works best on natural teeth with yellow or brown staining from coffee, tea, red wine, tobacco or aging. Grey staining caused by certain medications or an old injury often responds less well, and in those cases porcelain veneers or cosmetic bonding may give a better result.

Before whitening, we check for cavities, worn enamel and gum inflammation, because these should be treated first. Whitening is generally postponed during pregnancy and breastfeeding.

If your teeth are sensitive, we may suggest a desensitizing toothpaste in the weeks before treatment, or start you with take-home trays, which use a gentler gel over a longer period.

What to Expect During In-Office Whitening

1. Consultation and exam: we check your teeth and gums and record your starting shade.
2. Preparation: your lips and gums are protected so the gel only touches your teeth.
3. Whitening: the professional gel is applied and activated in short cycles, with comfort checks between cycles.
4. Results: we compare your new shade with your starting shade.
5. Aftercare: you go home with instructions to protect your results, plus the option of custom trays for touch-ups.

Professional Whitening vs. Over-the-Counter Products

Whitening strips, toothpastes and LED kits are widely available, but they work differently from treatment supervised by a dentist:

What Causes Tooth Discolouration?

Tooth staining is extremely common and can be caused by lifestyle factors, dietary habits, and the natural aging process. Understanding the cause of your discolouration helps us recommend the most effective teeth whitening treatment in Guelph.

Common causes of stained or yellowed teeth include:

• Coffee, tea, red wine, and dark-coloured beverages
• Tobacco use (smoking or chewing)
• Certain medications (e.g., tetracycline antibiotics)
• Natural aging and enamel thinning
• Fluorosis from excessive fluoride exposure in childhood
• Trauma or injury to a tooth
• Poor oral hygiene leading to surface staining

How Long Does Teeth Whitening Last?

With proper care, professional teeth whitening results in Guelph typically last 6 months to 2 years. The exact duration depends on your diet, lifestyle habits, and how consistently you maintain your oral hygiene routine.

Tips to extend your whitening results:

• Limit staining foods and drinks (coffee, tea, red wine, berries)
• Rinse with water immediately after consuming staining beverages
• Avoid tobacco products
• Brush twice daily with a whitening-friendly toothpaste
• Schedule regular dental cleanings at our Guelph clinic
• Use your custom take-home trays for periodic touch-ups
