Does teeth whitening actually work?
Yes, professional teeth whitening genuinely works because it uses higher, dentist-supervised concentrations of peroxide that break down stains the toothpaste on your shelf simply can't reach. Most patients lighten several shades in a single visit or over a couple of weeks with custom take-home trays. We offer professional teeth whitening in Hamilton as part of our cosmetic dentistry services, tailored to your starting shade and sensitivity.
Professional whitening vs at-home kits: what's the difference?
The main difference is concentration, supervision, and protection. In-office and dentist-provided take-home systems use stronger, professional-grade gel and custom-fitted trays that keep the gel on your teeth and off your gums. Drugstore strips and trays are weaker and one-size-fits-all, so they work slowly and often unevenly. The American Dental Association recommends talking to your dentist before whitening to protect your gums and enamel.
How long does teeth whitening last?
Professional whitening results typically last one to three years, and longer if you maintain them. Lifestyle is the biggest factor, coffee, tea, red wine, and tobacco all re-stain teeth over time. Many patients keep a set of custom trays and do a short top-up once or twice a year to stay bright, which is far cheaper than starting over.
Is teeth whitening safe? Will it hurt my teeth?
When done or supervised by a dentist, whitening is safe and does not damage enamel. The most common side effect is temporary tooth sensitivity that fades within a day or two, which is why a professional approach matters, we adjust the concentration and timing to your teeth and treat any existing sensitivity first. We always check for cavities and gum issues before whitening, since whitening an unhealthy mouth can cause real discomfort.
Why are my teeth stained in the first place?
Stains come in two types. Surface (extrinsic) stains from food, drinks, and smoking respond very well to whitening. Deeper (intrinsic) discolouration from aging, certain medications, or old injuries is more stubborn and may not fully respond to bleaching. A quick exam tells us which type you have and how much improvement to realistically expect, no surprises.
What whitening won't fix
Whitening only lightens natural tooth enamel, it will not change the colour of crowns, veneers, bonding, or fillings. If you have visible restorations or deep intrinsic stains, options like composite bonding or veneers may give you a more even result, sometimes combined with whitening first. Our guide to cosmetic dentistry in Hamilton covers how these treatments work together.
