Lol I ate too much pineapple?!

Wait for the flesh to grow back I guess :) If it's really sore, bonjela or iglu mouth ulcer gels will probably help.

Viv is wrong; you're not allergic (as I suspect you already know). For those who aren't aware, raw pineapple contains (mild) enzymes that eat the flesh in your mouth. Put a slice between your teeth and your lips for a few minutes and see for yourself.

Stop eating pineapple. You are slightly allergic to fresh pineapple, You may be able to eat cooked or tinned or canned pineapple but not for a while.

Just drink water. Nothing acidic, no juices, no alcohol, no tea or coffee or pop. Talk to the doctor about a mild mouth wash. Maybe just a weak herbal tea like pure chamomile tea. Don't eat for a while either, maybe a day or two - you won't starve. Let your mouth rest. Stop talking, no cigarettes, no lip locking.

Get ready for a poop fest for sure,

Use vitamin D around all sore areas!

i know how that feels... maybe drink some milk or eat bread to soften it up a bit.
