.First off, how do teeth get stained in the first place? “All teeth are made out of tubes—like pores,” , FAGD, founder of Brooklyn Mint, a dental practice in New York, previously told Glamour.

When you eat or drink something richly pigmented—red wine, turmeric, tomato sauce, coffee—those pigments can penetrate the porous structure of enamel, creating that stained or dingy appearance.The best whitening toothpastes work by using one of two primary whitening methods: chemical bleaching and physical abrasion.The first method involves peroxide. “Peroxide acts as a bleaching agent to change the color of your teeth.

If a toothpaste claims to whiten, it should contain hydrogen peroxide or carbamide peroxide,” says , a dentist certified in biomimetic dentistry in New York.

Both chemicals “react with the molecules causing stains on the teeth,” , a board-certified cosmetic dentist based in Beverly Hills, previously told Glamour. “This reaction helps break down the stains into smaller, less visible particles, leading to a brighter and whiter appearance of the teeth.”The second way toothpastes can whiten is through physical abrasion, or exfoliation, of the enamel.
