LPT: don't brush your teeth immediately after vomiting!

When I was pregnant, I vomited every day, multiple times a day from my 9th week to my 40th. I brushed my teeth each time because of course you feel gross. Shortly after our baby was born, my dentist told me that brushing right after vomiting actually grinds the acid into your teeth and can make the damage substantially worse. His advice: rinse your mouth with water or mouthwash and brush 30 minutes after. 6 new cavaties and 2 cavities from my childhood that needed replacing makes me want to believe what my dentist says is true.
