Is it harmful to eat something hot and drink something cold afterwards?!
Answers:
Drinking cold liquid immediately right after a hot food or beverage damages the teeth definitely. The tooth enamel, being 97% inorganic in composition, is ceramic in nature and not as elastic or pliable as the other parts of the body. A sudden change of temperature from hot to cold will dissociate the atoms of the hydroxyl-apatite crystals of the enamel, hence the appearance of cracks. These self-inflicted damages are permanent and does not repair.

I've honestly never heard this before. I've always eaten hot food and had cold drinks. If this was true, then lunches like soup and salad wouldn't be as popular as they are. Likewise you wouldn't be served cold drinks with hot meals in restaurants.
What if you took a bite of something that was too hot and burned your mouth? You need to drink something cold immediately to cool the food and soothe your mouth, otherwise you'll just burn it worse.
No, i always have a cold drink with a hot meal and im sure most people do, think when you go out for a meal most people have a cold drink with hot food, if anything it will stop burning hot soup burning the inside of your stomach if you have a cold drink with it
