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.
BTW side note as a fellow tight teeth person: I’ve started asking hygenists not to floss my teeth during the cleaning. Inevitably they smash the shit out of my gums trying to force their floss between my teeth.
