Natural and herbal ways to support your teeth

I have wanted to share this picture for a long time. I have been exploring ways to support my oral hygiene in a natural way for a long time. With the help of herbs. Partly I want to avoid hormone disrupting substances (due to thyroid problems), partly I want to strengthen my teeth that suddenly had a tendency to caries. It has helped me a lot to use more tools and herbs in my daily routine.

What do you think? Do you use alternative ways to care for your teeth and mouth?
