Your smile is one of the first things people notice — and a bright, white smile can instantly lift your confidence. But over time, lifestyle habits like sipping coffee or tea, enjoying red wine, or simply the natural aging process can leave your teeth looking dull.
If you’ve been avoiding photos or feeling less confident when you smile, professional teeth whitening may be exactly what you need to bring back that sparkle.
At Dr. William Rodriguez & Associates in Mississauga, our cosmetic dentistry team offers safe, comfortable, and highly effective whitening treatments designed to reveal a brighter, more beautiful smile.

Why Teeth Lose Their Natural Whiteness
Even with daily brushing and routine dental care, teeth can still become stained. Common reasons include:
- Coffee, tea & red wine: Strong pigments cling to enamel.
- Smoking or tobacco use: Causes deep, persistent staining.
- Color-rich foods: Sauces, berries, and spices can darken teeth.
- Aging: Enamel thins, exposing the yellowish dentin beneath.
- Medications: Certain prescriptions can affect tooth color.
Over-the-counter products may help surface stains — but they often can’t reach deeper discoloration.
