this is also why i actually think hard candy that's basically just solid sugar, is the best kind.
Because you're sucking on it and the sugar dissolves into your saliva you get a lot of sweetness that lasts a long time, rather than constantly shoveling stuff into your mouth.

Now, i have no clue how terrible it is for your teeth to soak your mouth in sugar water for hours on end, but it's not like that doesn't happen with other candies, and i'd imagine it's pretty good to avoid chewing on sugar?
