When I was buying toothpaste and mouthwash, I bought Spry products for some yrs.

Search - spry mouthwash - iHerb.com

Now for a couple yrs I make my own TP of coconut oil base. And use no more mouthwash, but rinse with hydrogen peroxide before bed.

Grape seed extract keeps my gums healthy and tight. Been taking grape seed ex 22 yrs. It's never too late to start, I was 57 when I first found it, now 79.
