Key features & specs

How it compares

Compared to the Philips Sonicare Protective Clean 5100, the Burst Sonic Electric Toothbrush uses a bio-based bamboo handle and extra-soft bristles that are specifically designed for gum comfort. While the Oral-B iO Series 5 offers real-time pressure feedback, Burst focuses on natural materials and sustainability. For price-sensitive shoppers, the Burst toothbrush is more affordable and is available on a subscription model with recyclable heads.

What to know before buying

1. The brush head is made from plant-based materials, so it is softer than standard nylon—swap it every month if you have heavy plaque buildup.
2. It uses a single AAA battery (included) that lasts up to 30 days; no charging cord required.
3. Select the ‘Sensitive’ mode for the gentlest sonic speed, ideal for tender gums.
4. The bamboo handle is compostable at end of life, but remove the battery before composting.
5. Subscribe to Burst’s head replacement program to receive a new head every 3 months at a discounted price.
6. Store the toothbrush in a cool, dry place to prevent the bamboo from absorbing moisture.

"I love that my toothbrush handle is made of bamboo and the bristles are infused with charcoal. My gums feel so much better since I switched—they’re not as red or puffy." — Verified buyer

Sustainability & ethics

As a Certified B Corp, Burst meets rigorous standards of social and environmental performance. The bamboo handle is FSC-certified, and the bristles are nylon (though not biodegradable), but the company offsets this by offering a take-back program for used heads. The packaging is 100% plastic-free and made from recycled cardboard printed with soy ink. Burst donates a portion of profits to oral health charities.

Frequently asked questions
