Professional teeth whitening at Smile On You Dentistry delivers results that over-the-counter strips and supermarket kits simply cannot match — because the concentration of whitening agent used in a clinical setting is significantly higher, and the application is controlled to protect your gums and soft tissue throughout. Our Lake Forest team offers both in-chair whitening for immediate, dramatic results and take-home tray systems for patients who prefer to whiten gradually at their own pace. Most patients achieve a shade improvement of 4–8 levels in a single in-chair session, with results that last 12–24 months depending on diet and oral hygiene habits.

Most patients at Smile On You Dentistry achieve a 4–8 shade improvement with professional in-chair whitening, though the final result depends on the original shade and cause of discolouration — intrinsic staining from tetracycline, for example, responds more slowly than surface staining from coffee or wine. Results typically last 12–24 months, and a simple take-home top-up treatment once or twice a year can maintain your shade indefinitely.
Some patients experience mild, transient sensitivity for 24–48 hours after professional whitening — this is a normal response to the peroxide gel temporarily opening the dentinal tubules. At Smile On You Dentistry, we use desensitising agents as part of our whitening protocol and can recommend a lower-concentration take-home system for patients with a history of sensitivity, achieving excellent results with minimal discomfort.
Whitening agents only affect natural tooth enamel — they do not change the shade of porcelain, ceramic, or composite restorations. If you have visible restorations in your smile zone, your clinician will discuss the sequencing of whitening and any restoration replacement needed to ensure a consistent, matched result across your full smile.
