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 🤔
Consult your dentist.
I use different types of cleaners for different parts of my teeth.
I'm a gross dude who doesn't take good care of my health. I didn't even really know what flossing was for most of my life. The first time I ever went to a dentist was when a molar crumbled in the middle of a BLT while I was at work during my late twenties. So maybe don't take my dental advice ...
... But I use bamboo floss picks repeatedly so long as they are intact, haven't fallen anywhere contaminated, and have no visible debris on them. Makes me feel a lot less wasteful.
