ELI5 Why does my mouth produce slime after I consume drinks with a high sugar content?
gpt
Little tiny bugs called bacteria need just a few things to live - food, water and warmth.  Guess what?  Your mouth has LOTS of all three of those!  The bacteria in your mouth start as little groups, when they suddenly get a lot of sugar to munch on, they begin to multiply really quickly.  All the bacteria start having kids and grandkids and great-grandkids faster than you can blink.  The bacteria family works better as a group, so the bacteria produce a sticky slime (called extracellular polymeric substance) so that they can stick together and stick to their food source (you!).  This is called a biofilm.  Sugary drinks may make this the most noticeable to you, but they aren't the only thing that bacteria families eat - they'll eat anything.  You probably have a biofilm on your teeth right now.  Gross!  This is why it is so important to brush and floss your teeth at least twice a day.
