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.
Depending on what you're willing to spend Id recommend a water flosser. No plastic pollution, can use tap water as a default or if you're fancy do a mouthwash diluted a bit with water. Insanely efficient, and gives a level of mouth clean I have yet to be able to beat. The first time I used mine I was blown away by how much shit came out of my mouth. Anyway, best of luck!
