GLO vs. OTC Whitening: A Side-by-Side Comparison

When it comes to whitening your teeth, you have options. There are the pharmacy aisle staples: strips, gels, and trays promising a brighter smile. And then there’s GLO Professional Whitening, the system trusted by dental professionals and designed to deliver fast, comfortable, and lasting results.

Here’s how GLO stacks up against the OTC alternatives:

Feature	OTC Strips & Trays	GLO Professional Whitening
Comfort	Often ill-fitting, can irritate gums	Snug, custom-fit mouthpieces designed for comfort
Sensitivity	High risk of temporary pain and sensitivity	Minimized sensitivity thanks to enamel-safe formulas
Speed of Results	Weeks of daily treatment for subtle change	Noticeable results in as little as 16 minutes (in-office) or with at-home kit over days
Effectiveness	Limited whitening power	Teeth can whiten up to 12 shades with professional-grade gel
Long-Term Care	May not maintain results	At-home kits allow patients to maintain in-office whitening for lasting brightness

The takeaway? While OTC products may be convenient, they often fall short on comfort, safety, and real results. GLO Professional Whitening offers a superior experience, combining professional-grade effectiveness with a pain-free, enjoyable whitening routine.

Whether you choose in-office sessions, at-home kits, or a combination of both, GLO ensures that your smile isn’t just brighter—it’s healthier, more comfortable, and longer-lasting.
