Teeth Whitening: What It Costs and What Actually Works

Whiter teeth are the most requested cosmetic change in dentistry — and the most confusing to shop for. Drugstore strips promise miracles for $40; some offices quote $600. What's the real difference? Here's the honest version.

Your three real options

Whitening strips and pastes ($20–$60). Over-the-counter products use low concentrations of peroxide. They do work — slowly, modestly, and mostly on mild surface staining. The common complaints are uneven results (strips don't hug the curves of your teeth) and sensitivity from overuse. Reasonable for a young smile with minor stains; frustrating for much else.

Custom take-home trays ($200–$500). Made from molds of your teeth, filled with professional-strength gel, worn for a few hours a day over one to two weeks. Because the trays fit precisely, the gel goes where it should and results are even. This is the workhorse option: professional results, moderate price, and you control the pace.

In-office whitening ($300–$800). The strongest gels, applied by professionals with your gums protected, often in a single visit. If you have an event coming — a wedding, photos, an interview — this is the "whiter today" option. Many patients pair a single in-office session with take-home trays for touch-ups.

What whitening won't do

This is the part the commercials skip:

• Crowns, veneers, and fillings don't whiten. If you have visible dental work, whitening around it can create mismatched colors. This is exactly why a quick exam before whitening saves money — sometimes the right answer is whitening first, then matching new dental work to the result.
• Gray or tetracycline staining responds slowly and sometimes incompletely. Deep internal discoloration may call for veneers or bonding instead.
• Whitening doesn't last forever. Coffee, tea, red wine, and tobacco bring stains back. Expect touch-ups every 6–18 months depending on habits.

Is it safe?

Supervised whitening is very safe. The most common side effect is temporary sensitivity, which is manageable with the right gel concentration and schedule — one more reason professional guidance beats guessing at the drugstore. We don't recommend whitening for pregnant patients, for teeth with untreated cavities or gum disease (fix those first — that's what a deep cleaning is for), or for kids.

The honest recommendation

Start with an exam, not a product. In fifteen minutes, Dr. Jaquez can tell you whether your staining will respond to whitening, whether existing dental work complicates things, and which option fits your budget — in English or Spanish.
