Question - how long can sperm survive in the mouth? If you wait a day and eat and drink and brush your teeth during that day, can the sperm still live?

Hi there ihaveaquestion, and welcome to Scarleteen!

Sperm cells are actually pretty delicate, and require very specific living conditions, which are only found inside the testes (where they're made), inside the vagina/uterus (where they're supposed to go), and in fabricated lab conditions. So, to answer your question, if they're in the mouth, and not in one of those ideal environments, they usually won't live for more than a half an hour. Certainly not over a period of a day.
