The Whitening Lab is a cosmetic teeth-whitening brand based in Gray, Maine, serving Greater Portland and surrounding areas. Founded in 2022 by dental professionals, it focuses on professionally delivered whitening services and take-home maintenance products. Treatments are performed by licensed or certified professionals, with an initial assessment used to tailor the experience and maintenance plan.

In-lab services include a comprehensive first visit with a 60-minute whitening session, as well as shorter 60- and 40-minute touch-ups for returning clients. Each session finishes with Recovery Serum. The Lab also offers custom upper and lower bleaching trays for home use, supplied with professional whitening gel and usage guidance; refill syringes are available.

For ongoing care, the brand sells ORLA, its take-home line of whitening strips, brush-tip pens, and Recovery Serum, including a complete routine bundle. Products are made in the Gray studio and shipped to customers. The Whitening Lab reports that many clients achieve five to twelve shades of brightness in one session, though results vary.
