I was always a snacker / grazer until about 4 years ago.
I realized too late what eating (though small amounts) throughout the day and never flossing did to my teeth!
Major dental work!
But almost magically my emotional attachment to food fell away ... totally.
Now i need to remember to eat and sometimes force myself to eat.
After a life time of being addicted to food (especially to sweets and salt snack like chips) that addiction literally disappeared and almost overnight.
I'm no long a snacker and i never eat anything without brushing and flossing afterward.
So i second what you say ... take care of your teeth young people. Start now. Brush and floss after every meal and get your teeth cleaned on a regular basis.
I'm glad you had no pain btw.
When i read the title of your post i just cringed. Yikes!
