In-Office Teeth Whitening — What You Get
In-office professional whitening at Red Rose Dentistry uses a high-concentration peroxide gel activated by a specialized light. Results appear in a single 60–90 minute appointment — making it ideal for patients with an upcoming event, wedding, interview, or who simply want immediate results without weeks of nightly trays.
- Preparation: teeth are cleaned, gums are protected with a barrier
- Gel is applied to teeth and activated (typically 2–3 rounds of 15–20 minutes each)
- Results visible same-day: 4–10 shades whiter depending on starting colour and stain type
- Sensitivity: some patients experience temporary tooth sensitivity for 24–48 hours afterward — normal and manageable
Take-Home Whitening — What You Get
Custom take-home whitening trays are made from impressions of your teeth — they fit perfectly and hold the professional-strength gel against every surface evenly. This is what makes them dramatically more effective than pharmacy whitening strips (which slip, miss edges, and use lower-concentration gel).
- Custom trays fabricated to your exact tooth shape (1–2 appointments: impression + tray pickup)
- Professional-strength whitening gel provided (10–22% carbamide peroxide, vs. 3–6% in Crest Whitestrips)
- Typically worn 30–60 minutes per day (day formula) or overnight (night formula) for 2–3 weeks
- Trays are reusable for years — you only need to purchase gel refills for maintenance ($60–$120/year)
How Long Does Professional Whitening Last?
Professional whitening results typically last 1–3 years, with variation based on diet and lifestyle. Here is what affects longevity:
| Factor | Effect on Whitening Duration |
|---|---|
| Coffee, tea, red wine | Accelerates re-staining — can reduce duration to 6–12 months in heavy users |
| Smoking or tobacco | Dramatically accelerates staining — whitening lasts only months without cessation |
| Good oral hygiene | Extends results — clean teeth stay white longer |
| Annual touch-up trays | Extends results indefinitely for most patients — one week of nightly trays per year maintains the result |
| Teeth with intrinsic staining (tetracycline, fluorosis) | Intrinsic staining responds much more slowly — may require extended treatment or veneers for severe cases |
Does Teeth Whitening Work on Crowns, Veneers, or Bonding?
No — whitening gel does not change the colour of dental restorations (crowns, veneers, composite bonding, or fillings). It only works on natural tooth enamel. This is important to understand before whitening if you have visible restorations on front teeth — the natural teeth may whiten while the restorations stay the same shade, creating a mismatch.
We identify this at your consultation and advise accordingly. In some cases, whitening first and then replacing restorations to match is the most effective approach.
Is Teeth Whitening Safe?
Yes — professional teeth whitening is one of the most studied cosmetic dental procedures and is safe for the vast majority of patients when supervised by a dentist. The most common side effect is temporary tooth sensitivity, which resolves within 24–72 hours. We use desensitizing agents in the gel and advise on sensitivity management before your appointment.
Teeth whitening is NOT recommended for:
- Children under 16 (enamel is still developing)
- Pregnant or nursing women
- Patients with severe enamel erosion or active tooth decay (these must be treated first)
- Patients with extreme pre-existing sensitivity
Frequently Asked Questions — Teeth Whitening Cost in Hamilton
Q: Is professional whitening worth the cost over pharmacy strips?
A: For most patients, yes. Professional whitening achieves noticeably more dramatic results in less time, using higher-strength gel that actually penetrates staining rather than just removing surface film. Custom trays are also significantly more comfortable and effective than strips. If you have visible staining (coffee, tea, aging), the difference is immediately apparent.
Q: Does dental insurance cover teeth whitening in Hamilton?
A: No — purely cosmetic whitening is not covered by dental insurance in Ontario. However, if whitening is part of a treatment plan that includes a functional component (e.g. replacing old restorations and whitening to match), some elements may receive partial coverage. CDCP does not cover whitening.
Q: Can I whiten my teeth if I have sensitive teeth?
A: Often yes — we use desensitizing formulas and lower-concentration gels for patients with sensitivity concerns. Sensitivity is managed, not a hard stop. Discuss this at your consultation.
Q: How many shades whiter will I get?
A: Realistically, 4–8 shades is typical for most patients with common coffee/tea staining. Patients with severe intrinsic staining (tetracycline antibiotics, fluorosis) may see less change. We show you your starting shade and set realistic expectations at your consultation — no over-promising.
