Professional Teeth Whitening

Professional teeth whitening uses a clinical-strength peroxide gel to break down stains inside the enamel and dentin — going deeper than any over-the-counter strip can reach. Royale Dental in Hialeah offers two paths depending on how fast you want results, how sensitive your teeth are, and how much you want to do at home versus at the office. Both deliver dramatically better and longer-lasting results than drugstore products, all under dental supervision so it’s safe for your gums and enamel.

What causes teeth to darken

Two kinds of staining respond to whitening:

• Extrinsic stains — coffee, tea, red wine, tobacco, dark berries, and pigmented sauces build up on the enamel surface over time. These come off readily with whitening.
• Intrinsic stains — the dentin layer beneath the enamel naturally yellows with age, and certain conditions (tetracycline use, fluorosis, trauma) cause deeper discoloration. Whitening helps but takes longer; for very deep intrinsic staining, porcelain veneers may be a better option than repeated whitening cycles.

Whitening cannot fix gray teeth from old root canals (those need internal bleaching or a crown), nor change the color of any existing crown, veneer, or filling.

In-office whitening

The fast option. One appointment, dramatic result.

• One visit, 60–90 minutes — same-day brighter teeth before you walk out
• Up to 6–8 shades brighter in a single session, depending on starting color
• Gum isolation — we paint a protective barrier on the gums so the high-concentration gel reaches only the enamel
• Activated gel — applied in 15-minute cycles, sometimes with a light to accelerate the reaction
• Immediate result — you see the new shade in the mirror at the end of the visit
• Best for — events, weddings, big meetings, or patients who simply want it done in one shot

Custom take-home trays

The gentler option, with a longer ramp.

• Custom-fit trays taken from a digital scan of your teeth, plus professional-strength gel
• Wear nightly for 1–2 weeks — 30 minutes to overnight per session, depending on the protocol
• Gentler ramp — better tolerated by patients with sensitive teeth
• Trays are reusable for touch-ups every 6–12 months — long-term, this is the most cost-effective option
• Best for — patients who prefer to whiten at their own pace, or who anticipate doing periodic touch-ups

Many patients combine the two: in-office for a fast initial result, custom trays for maintenance.

Who’s a good candidate

Whitening works best on:

• Healthy teeth without active decay
• Healthy gums without significant recession
• Yellow or brown discoloration (responds best); gray and bluish stains respond less predictably
• Patients without veneers, crowns, or large bonded fillings on the front teeth (those won’t change shade)

We screen first for cavities, gum disease, and visible cracks at a routine exam — those need treatment before whitening so the gel doesn’t reach the nerve. If you’re considering whitening as part of a fuller smile makeover with Invisalign and veneers, we sequence the order so each step doesn’t undo the next.

Sensitivity management

Mild tooth sensitivity in the first 24–48 hours after whitening is normal — it usually resolves on its own. We minimize it by:

• Pre-treating with a desensitizing fluoride before the in-office session
• Recommending potassium nitrate toothpaste (Sensodyne) for two weeks before and during treatment
• Adjusting gel concentration or session length if you’ve had sensitivity in the past
• Avoiding very hot or cold foods for the first 48 hours after treatment

Patients with chronically sensitive teeth often do better with the take-home tray protocol at lower concentrations, spread over more nights.

How long results last

Most patients see noticeable brightness for 1–3 years before considering a touch-up. The real determinants are habits:

• Coffee, tea, red wine, dark sauces, and tobacco re-stain teeth fastest
• A water rinse after staining drinks helps significantly
• Routine cleanings every 6 months remove surface stain before it sets in

Custom take-home trays are the cheapest long-term maintenance — one tube of gel and a weekend of nightly wear refreshes the shade.

Cost

In-office whitening at Royale Dental is $300 per arch — $600 to whiten both upper and lower arches in a single visit. Custom take-home trays with gel run $225 per arch, or $450 for both arches including the custom-fit tray fabrication. We discount the package when patients combine in-office whitening with take-home trays for ongoing touch-ups. Whitening is cosmetic and not covered by dental insurance — but bring your card anyway and we’ll verify benefits in about 60 seconds for any underlying restorative or preventive work that pairs with the visit. Payment plans from around $99/mo through CareCredit and Alphaeon are available for smile-makeover packages that include whitening alongside veneers or Invisalign.
