More sustainable options, like bamboo toothbrushes, have definitely gained popularity within the last few years.

How did the brand do it?

I put both to the test to see how well they could clean my teeth.

Thankfully, this manual toothbrush hits those requirements, but it doesn’t have the ADA seal.

The soft-bristle brushes do provide a thorough clean, unlike some of the other sustainable toothbrushes I’ve used.

All in all, I was happy with the results from both brushes.

Meanwhile, the brush heads are made to be disposed of after three months, to be exact.

The brand has created apartnership with Terracycle, which has a service you might use to recycle these heads.

You hold onto the handle and add new heads infinitely, hence the name Keep.

Refill kits with two heads each retail for $5.
