We Asked Dentists: What's the Best Whitening Toothpaste of 2025?

cnet.com See Full Bio 2025-12-01 02:32:00

Why we like it: Colgate Optic White Pro Series toothpaste is one whitening toothpaste that Dr. Fatima Khan, a dentist in Houston, Texas, recommends. Some of her reasons for recommending it include its trusted brand name and its 5% hydrogen peroxide whitening agent. Unlike other whitening agents that work by removing stains on the surface of the tooth, hydrogen peroxide can get inside the tooth so it whitens intrinsically as well as extrinsically. Sachar also recommends this toothpaste, saying,

The Wild, Citywide Scavenger Hunt That Ate San Francisco

On a Wednesday night in August, hundreds of people gathered in the lobby of Apple Cinemas in central San Francisco. To gain admission to the event, attendees had to say a secret code word to the crew working the door: three giggling children wearing oversize “SECURITY” caps. The throng inside hunted for QR codes on the walls and admired a makeshift art gallery that showcased a collection of paintings, each referencing a famous historical work—Vermeer’s Girl With a Pearl Earring, Munch’s The Scr

Rupert's Property

You can cut a hole in a cube that’s big enough to slide an identical cube through that hole! Think about that for a minute—it’s kind of weird. Amazingly, nobody could prove any convex polyhedron doesn’t have this property! It’s called ‘Rupert’s property’. Until this week. This week Steininger and Yurkevich proved there is a convex polyhedron that you can’t cut a hole in big enough to slide the entire polyhedron through the hole. It has 90 vertices, and apparently 240 edges and 152 faces. To

Google's New Pixel Studio Is Weirdly Obsessed With the iPhone

Pixel Studio launched on the Pixel 9 series last year, but the Pixel 10 Pro allowed me to spend time testing Pixel Studio using a more advanced generative AI model. The result is better quality images, a much deeper understanding of keywords and a wider range of image styles that can be created.

We tend to lump all mammoths together as big, hairy elephant-like beasts with enormous tusks. But there were a number of mammoth species, including less furry ones that inhabited temperate regions. And the furry ones include at least three species: the Eurasian steppe mammoth, the Arctic-specializing woolly mammoth, and the late-evolving North America-only Columbian mammoth. Because these species inhabited the Arctic, it has been remarkably easy to obtain DNA from them, providing a genetic pict

For example, how common is it really? Are the chatbots really driving people crazy, or just catching the attention of people who were crazy already?
