What is Whitening Method Match?
A teeth-whitening recommendation matches your sensitivity, staining type, budget, timeline, and prior history against the practical whitening options: in-office sessions, custom take-home trays, OTC strips, a combo plan, or a cleaning-first visit. It accounts for the fact that whitening only works on natural enamel and looks uneven over old restorations.
The Formula
Best Match = (Sensitivity Tolerance) + (Stain Type) + (Budget Band) + (Timeline)
Each input narrows the option set; the strongest single signal is usually sensitivity, which rules out high-concentration options for some patients regardless of budget.
Worked Example
A 34-year-old with mild coffee staining, no significant sensitivity, $300 budget, willing to spend 2 weeks on it.
- Sensitivity: not a constraint
- Stain type: surface stain from coffee, responds well to peroxide
- Budget: $300 fits custom take-home trays
- Timeline: 2 weeks aligns with take-home wear schedule
📌 Custom take-home trays are the strongest single match, with OTC strips as a runner-up for someone testing whitening first. In-office would also work but exceeds the stated budget.
Why This Matters
Sensitivity changes everything
High-concentration whitening on sensitive teeth without prep gel produces a few uncomfortable days for a modest shade gain. Matching to sensitivity tolerance is the most common avoidable mismatch.
Existing restorations do not bleach
Crowns, veneers, and old composite fillings retain their original color while natural teeth lighten. A consult before whitening identifies whether restorations will need to be replaced afterwards.
Intrinsic stains need a different approach
Tetracycline staining, fluorosis, and trauma-related discoloration sit inside the tooth structure rather than on the surface. Standard peroxide whitening has limited effect on these; veneers or bonding are often the realistic path to the desired shade.
Common Mistakes
❌ Stacking OTC strips back to back beyond 14 days
Strips are dosed to a 2-week course. Doubling up sessions or running consecutive courses raises sensitivity sharply without much extra shade gain.
❌ Whitening over untreated decay or gum inflammation
Peroxide intensifies sensitivity in cavities and irritated gums. Addressing those first lets the whitening itself be uneventful.
❌ Expecting permanent results without maintenance
Whitening results fade over 6 to 24 months depending on diet and habits. Coffee, tea, red wine, and tobacco accelerate re-staining. A brief touch-up course every 6 to 12 months maintains results at a fraction of the initial cost.
Industry Benchmarks
| Category | Good | Average | Poor |
|---|---|---|---|
| Shade improvement (in-office single session) | 4-8 shades | 3-6 shades | 1-3 shades |
| Shade improvement (take-home trays, 2 weeks) | 4-8 shades | 3-5 shades | 1-2 shades |
| Shade improvement (OTC strips, 2 weeks) | 2-4 shades | 1-3 shades | No visible change |
