Can I use toothpaste to clean my engagement ring?

No. You should not use toothpaste to clean your engagement ring. Toothpaste is for teeth, not for a ring that’s going to live on your hand for forty years. I’ve had to re-polish and re-rhodium enough pieces after this exact experiment to tell you the same thing every time: keep the Crest away from the platinum and the pavé.

Toothpaste is a mild abrasive. That’s the whole point of it on enamel. But the stuff that removes coffee stains from your molars also puts micro-scratches into 14k and 18k gold, dulls rhodium plating on white gold, and hazes the surface of softer stones. If your ring has a diamond center and a gold band, the diamond itself won’t scratch, but the metal will. And if the ring has any small stones in a pavé or channel setting, the toothpaste grit works its way under the prongs and behind the stones, where it’s nearly impossible to rinse out.

Whitening toothpaste is worse. Those have extra abrasives plus hydrogen peroxide, which can react with some treated gemstones and strip oils from emeralds. If your engagement ring is an emerald, an opal, a pearl, or turquoise, toothpaste can ruin the stone’s surface in one scrubbing. Don’t test it.

Last March a client named Nicole brought in a white gold engagement ring that had been cleaned with toothpaste for about a year. The shank looked frosted, not polished. The rhodium was gone in patches. She needed a re-polish and a re-plate, which ran her $95, and she was honestly more upset that no one had told her not to do it than about the money.

What to use instead

Warm water, a few drops of plain dish soap like Dawn, and a soft baby toothbrush. Soak the ring for ten or fifteen minutes, scrub gently around the setting and under the crown, rinse in warm water, and pat dry with a lint-free cloth. That’s it. Do that every other week and the ring will look better than most “professionally cleaned” rings on a jewelry counter.

If the ring has an emerald, opal, pearl, or any heavily included stone, skip the soak and just use a damp cloth. And if the ring has a lot of small pavé stones, bring it to a jeweler once a year for a steam clean and prong check. Toothpaste does not replace that. It just creates more work for me.
