Right to Repair

Whether it be electronics, automobiles or medical equipment, the manufacturers should not be able to horde “oem” parts, render your stuff useless if you repair it with aftermarket parts, or hide schematics of their products.

Wooden toothbrushes are the real green option ! Get the right one and they’re entirely biodegradable.
Electric toothbrushes are simply superior in terms of dental hygiene, no matter how well you think you brush.
But do they lead to better outcomes ? My teeth being extra clean is irrelevant to me if I don’t get cavities either way.
Which, afaik, can be prevented by “simply” not eating anything with added sugar. (Not so simple these days unless you cook everything yourself)
Yes they do. Plaque buildup leads to gingivitis and cavities. It is in one's best interest to reduce plaque not because it makes your teeth look good, but because it will help you not have receding gums when you are older which leads to exposed roots, root canals, tooth replacements, etc...

Here is a long term study

Both probing depth and clinical detachment loss of the teeth were improved with an electric toothbrush.
What are the bristles made of?
Depends. You'll need to check the package.
Only a few of them are 100% biodegradable, with bristles made from animal hair, vegetable oil or straw.
Most of the bamboo toothbrushes have bristles made from recycled nylon, so those aren't 100 biodegradable, but they are still produced a lot more environmentally friendly than plastic toothbrushes.
