i do that, sometimes i do postbrush, apply some toothpaste if i somehow rinsed after brushing. the sensitivity toothpaste works best for a tooth that maybe sensitive. you have to eat so much toothpaste to even get poisoned by the flouride. it was only ever concerns for children that are still going. some adults actually believe you still can get flourosis from toothpaste.

while i was looking at toothpastes to buy, online people are obsessed with the ones that whiten thier teeth(mildly or otherwise), they think flouride free they feel “more cleaner” they dont realize some of these off-brand toothpaste that has whitening, especially nHA(is apparently abrasive too) is just cleaning the plaque, food better than normal colgate, or crest. because its more abrasive, obviously some complained it dint change thier teeth health, thier cavaties returned, or it did nothing because its non-abrasive.

alot of these toothpaste has so much mintoil it can cause a burning sensation and some can cause allergies on the lips.
