The Mouthful Neighbourhood
📋 What it is
Your mouth hosts hundreds of microbe species; brushing keeps the balance healthy, not sterile.
🗣️ Coach says
Your mouth is a bustling microbe neighbourhood — hundreds of species live on teeth, gums and tongue. Most are fine, but if sugary films (plaque) build up, certain bacteria make acid that harms teeth. Brushing and flossing don’t sterilise your mouth — they keep the community in a healthy balance.
🧠 Memory hook
Mouth = hundreds of microbe species. Brushing keeps a healthy BALANCE (not sterile); plaque bacteria + sugar = acid.
😂 Giggle
Why is a vaccine like a practice drill?
Because it trains your immune system to recognize a germ before the real one ever shows up!
😲 Whoa!
The sticky film on unbrushed teeth (plaque) is a living "biofilm" — a microbe city complete with layers and structure, built in less than a day.
✅ Quick check: Why does eating lots of sugar raise the risk of tooth decay?
Say your answer out loud first — then reveal.
Certain mouth bacteria feed on sugar and produce acid that wears away tooth enamel.
Sugar fuels acid-making bacteria that damage teeth.
🧪 Try it! (2 minutes)
Run your tongue over your teeth before and after brushing — that smoothness is plaque biofilm removed.
