How does over-the-counter whitening compare to in-office whitening?

The whitening aisle is full of strips, gels and toothpastes, and social media is full of DIY tricks. Here's how they compare with professional whitening.

Published October 2026

Whitening toothpastes

Most whitening toothpastes work by gently polishing away surface stains. They can help keep your smile bright between cleanings, but they don’t change the natural color of your teeth very much.

Strips and trays from the store

Over-the-counter strips and gels use a bleaching agent, at a lower strength than professional products. They can lighten teeth gradually over a couple of weeks. Because they are one size fits all, they may not cover every tooth evenly, and the gel can irritate your gums.

Professional in-office whitening

In-office whitening, such as the Zoom whitening we offer, uses a stronger gel applied by our team while your gums and lips are protected. Results are noticeably brighter in a single visit, and we check your teeth and gums beforehand to make sure whitening is a good choice for you.

DIY trends to skip

Lemon juice, apple cider vinegar, baking soda scrubs and charcoal powders are popular online, but acids can erode enamel and abrasive powders can wear it down. Once enamel is gone, it doesn’t grow back, and thinner enamel can make teeth look more yellow, not less.

Things to know before you whiten

  • Restorations don’t whiten. Crowns, veneers, bonding and tooth-colored fillings keep their color, so they may need to be matched or replaced afterward.
  • Sensitivity is common for a short time after whitening. Tell us if your teeth are already sensitive.
  • Some stains need another approach. Discoloration from medication or an injury may respond better to bonding or veneers.
  • Healthy teeth first. Cavities and gum problems should be treated before whitening.
