When you chew celery, it is giving your teeth a general cleaning, which will reduce your chances of tooth decay.
Because, "these fiber-thick foods are like brooms, which can sweep away some food residues from teeth," explained Chen Lisheng, the attending dentist of MacKay Hospital.
On the other hand, the harder you chew, the more you can stimulate saliva secretion, balance the pH in the mouth, and achieve natural antibacterial effect.
How to eat?
When you are greedy, don't think about desserts and snacks. You can cut celery, cucumber and carrot into strips, grab them and chew them as soon as you are greedy, massage your gums and supplement the amount of vegetables in one day.
