I get dirty with every meal, but I'm always disposed of with zeal. What am I?

This is best for taking care of your teeth or hair, maybe not both simultaneously. This may imply a close encounter with death or danger or a nearby plant along a hiking trail

I’m chewed, not swallowed, sweet at first, stretch me right and see me burst. A playful treat of sticky fun, best enjoyed by nearly everyone.

Tweety Bird lives within me, Your lungs couldn't live without me. Shark divers often use me, Prisoners can't refuse me.

Red as a summer's blush, sweet as a pie, In cakes and jams, oh my, oh my! Nature's little heart-shaped treat, A burst of joy, a garden's feat.
