Looking to brighten your smile and boost your confidence? At Trio Dentistry in Mississauga, we offer professional teeth whitening treatments designed to safely and effectively remove stains, lighten enamel, and enhance the natural beauty of your smile.

Our whitening options include in-office treatments using systems like Zoom or Opalescence, as well as custom take-home trays for flexible, gradual results. Whether you’re preparing for a big event or just want a brighter smile, we’ll tailor your whitening plan to fit your goals.

What Causes Teeth Stains?

Tooth discoloration is common and can be caused by:

  • Coffee, tea, red wine, and dark berries
  • Smoking or tobacco use
  • Natural aging of the enamel
  • Certain medications or medical conditions


Fortunately, professional whitening is highly effective at removing surface and deep-set stains.

Types of Whitening Treatments We Offer

1. In-Office Whitening

Our in-office whitening treatments use professional-grade agents with hydrogen or carbamide peroxide and light-activated technology for dramatic results in just one visit.

We use trusted systems like Zoom and Opalescence, which provide:

  • Immediate whitening in under 60 minutes
  • Safe, controlled application by trained professionals
  • Whitening of up to 6–8 shades in one appointment


This is ideal for patients who want fast, visible results.

2. Take-Home Whitening Trays

Our custom take-home trays allow you to whiten your teeth gradually over 1–2 weeks using carbamide or hydrogen peroxide-based gels.

Features include:

  • Custom-fit trays made from impressions of your teeth
  • Adjustable wear time (typically 30–60 minutes daily)
  • Great for touch-ups or ongoing maintenance

3. Combination Whitening Plans

We also offer combined in-office and at-home whitening for longer-lasting brightness and consistent results. This approach is great for weddings, professional photoshoots, or special occasions.

Whitening Treatment Process

  3. Wear trays daily for 1–2 weeks as directed
  4. Follow-up checks for shade progress

We offer regular cleanings and periodic whitening gel refills to help you maintain your glow.
