To remove these tonsil stones I used a tip of my mom's make up brush because it's bigger and smoother than q-tips. I cleaned it and disinfected it before and after. I think it is easier to get them out this way both, the big stones and the little ones. I have lots of stones on both sides.
I found out that fresh garlic helps to slow down the formation. Listerine and mouth wash don't work well on tonsil stones because of the type of bacteria.
