I found information on two rechargeable toothbrushes, the Oral-B Pro 1000 and the Sonic Electric Toothbrushes for Adults. I also found information on the materials used in toothbrush bristles and the sustainability of toothbrushes in general.

Materials used in toothbrush bristles
- Toothbrush bristles are usually made from a man-made fiber material called "nylon," which is a kind of polyamide.
Sustainability of toothbrushes
- Plastic toothbrushes create a lot of trash that doesnt break down easily.
- With electric toothbrushes, youre typically tossing a little less plastic because its only the brush head thats replaced regularly.
- Some manufacturers now offer manual toothbrushes with replaceable heads.
- Some companies make manual toothbrushes from sustainable bamboo, compostable bio-plastic, or cellulose.
- Innovations in sustainable materials, like moving away from plastic to bio-based and biodegradable heads, make the most sense for consumable parts like toothbrush heads.
- The main body of an eco-friendly electric toothbrush needs to be as durable and long-lasting as possible.
