Good dental health is linked to heart and brain health.
But... Are you cleaning all sides of your teeth properly? E.g. a regular toothbrush can't get in between teeth ๐ค
Consult your dentist.
I use different types of cleaners for different parts of my teeth.
You can get biodegradable bamboo floss; it's what I use. Still single-use, but it's at least not gonna hang around for a thousand years and deteriorate into micro and nano-plastics.
