i wanted to share some info that has helped me and my gums/teeth.
my dentist recently told me you shouldn’t brush your teeth for a good 20 minutes after you eat. the acids are still in your mouth and can be abrasive to your gums and enamel.
in addition, i read this article about how making smoothies (with berries or acid fruit in them) can cause the same thing, if you brush your teeth too soon. and i have AT LEAST one (green) smoothie a day!
it occurred to me how a lot of people complain about receding gum lines, and i wonder if this is all there is to it.
now that i am waiting to brush, i have no more sensitivity in my gum line.
hope this helps.
