Heart of Hingham offers two professional whitening options depending on your schedule, goals, and sensitivity level.
For the fastest, most dramatic results, we offer Philips Zoom, the most widely recognized in-office whitening system in dentistry. Zoom uses a powerful, clinically proven hydrogen peroxide gel activated by a specialized light to lift deep stains and brighten teeth by several shades in a single appointment. The entire process takes about an hour, and you leave the same day with a noticeably whiter smile. Zoom also includes a post-treatment fluoride application to reduce sensitivity and protect enamel after the whitening process.
If you prefer a more gradual approach or want the flexibility to whiten on your own schedule, we offer professional-strength take-home kits with custom-fitted trays made precisely from impressions of your teeth. Unlike drugstore trays, the custom fit ensures consistent gel coverage across every surface for even, streak-free results. Most patients achieve their target shade within one to two weeks of daily use.
Dr. Sandhu will walk you through both options and recommend the approach best suited to your starting shade, sensitivity history, and lifestyle.
Professional whitening can lighten teeth by several shades, a meaningful, visible difference that patients consistently notice in photos and in the mirror. Exact results depend on your starting shade and the nature of your staining. Extrinsic stains from food and beverages tend to respond very well, while intrinsic discoloration (from antibiotics, fluorosis, or aging of the tooth itself) may require additional treatment or a different cosmetic approach.
To extend your results, it helps to limit staining beverages, use a straw when possible, avoid tobacco, and incorporate a whitening toothpaste into your daily routine. Touch-up treatments are easy and available whenever you feel you need a refresh.
Professional whitening costs vary depending on whether you choose in-office treatment or a take-home kit. In-office treatments generally range from $300 to $800 across dental practices, while take-home kits are typically less. Book a whitening consultation for current pricing and to find out which option fits your goals and budget.
With proper maintenance, professional whitening results typically last one to three years. Habits like drinking coffee daily or using tobacco will shorten that window, while diligent maintenance can extend it. Touch-up treatments are quick and available to keep your smile looking its best.
Yes, professional whitening is safe when performed under dental supervision. Before beginning treatment, Dr. Sandhu screens for any sensitivity concerns, gum health issues, or restorations that might affect the outcome. Temporary tooth sensitivity after whitening is common and normal; it typically resolves within a day or two of completing treatment.
Most healthy adults are excellent candidates for professional whitening. One important thing to know: whitening agents do not change the color of dental crowns, veneers, porcelain work, or composite fillings, so if you have significant restorations in visible areas, Dr. Sandhu will discuss how to approach your smile goals realistically. A brief consultation is all it takes to determine the right plan for you.
