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.
You can get floss holders that will reduce the amount of string you use. They’re not perfect but better than the ‘disposable’ ones.
