Drugstore strips fade fast and can leave uneven results — professional Teeth Whitening is calibrated to your enamel, not a generic formula. Smile Center Dentistry checks your enamel and gums before recommending a strength.

Not every patient should use the same concentration of whitening gel, so we don't treat every case the same way. We'd rather delay a whitening session than treat over a cavity we haven't addressed.

We calibrate gel concentration to your enamel condition, not a one-strength-fits-all approach. We adjust based on what your specific exam shows, not a default setting.
We check for cavities and gum recession before whitening, since treating over untreated decay can cause real pain. This exam is included in your visit, not billed as a separate add-on.
Both options use professional-grade gel, just at different concentrations and timelines. We help you decide based on your timeline and sensitivity, not just what's more profitable for us.
Desensitizing gel and post-treatment guidance are part of every whitening visit, not an upsell. We check in after your session if sensitivity was a concern going in.
Results and timelines vary by starting shade and enamel condition, and we're upfront about that.
A higher-concentration gel activated in the chair delivers visible results in about an hour. We monitor sensitivity throughout the session rather than applying gel and walking away.
Trays molded to your exact bite let you whiten gradually at home with a lower-concentration gel. We check your progress at a follow-up to confirm even results.
Realistic outcome expectations are set at this visit — whitening lightens natural enamel, not crowns or veneers. This appointment also flags any restorations that won't whiten along with natural teeth.
We adjust gel exposure time for sensitive patients rather than pushing through discomfort. Post-visit care instructions are given verbally and in writing.
Take-home touch-up trays let you maintain your shade without a full in-office visit each time. We recommend a schedule based on your diet and habits, not a generic interval.
Deeper staining from certain medications or fluorosis responds differently than surface staining and may need a longer protocol. Realistic expectations are set at your shade consult, not after treatment disappoints you.
We ask about sensitivity history when you book, so we're prepared for your specific case.
This quick exam determines whether in-office or take-home whitening fits you better.
In-office sessions take about an hour; take-home trays are fitted and explained the same visit.
You'll see your new shade compared to your starting point, plus a plan to maintain it.
"Did the in-office session before my wedding. Noticeably brighter after one hour and no sensitivity afterward."
"Take-home trays fit perfectly since they were molded to my actual bite, not a generic tray."
"Shade comparison before and after was a nice touch — I could actually see the difference, not just take their word for it."
"Honest about what whitening could and couldn't fix on my teeth — no overselling."
"Combined an in-office session with take-home trays for maintenance. Best of both approaches."
We compare your before-and-after against a shade guide so the improvement isn't just a guess. We'll give you a realistic expectation at your consult based on your current shade.
Professional whitening, properly calibrated, doesn't damage healthy enamel — that's why we check your teeth first. We monitor your enamel condition throughout treatment, not just at the start.
Typically six months to two years depending on diet, smoking, and oral hygiene habits. We'll recommend a realistic maintenance plan rather than a generic one-size interval.
No — restorations don't whiten the same way natural enamel does, which we check for during your consult. If a mismatch would result, we discuss options honestly before you commit to treatment.
Yes, with an adjusted gel concentration and desensitizing treatment built into your visit. We check in during treatment and adjust if sensitivity becomes uncomfortable.
Both use professional-grade gel; the choice usually comes down to your timeline and sensitivity level. We'll walk through the trade-offs honestly at your shade consult.
