It has to do with what you eat....the more calcium you eat the healthier your teeth are! :) If you eat tough things, then they chip your teeth.

Dry ice is frozen carbon dioxide (CO2).

No, people who are anemic often have a habit of chewing ice. The anemia happens first, it's not caused by the ice.

It breaks the hydrogen bonds between water molecules to aid in the melting process. Since this energy is used to break bonds, it can't heat the ice.

its just like saying, do humans enjoy the taste of icecream? or is it just instinct?

Usually it is caused by stress or sometimes restorations that are too high.  A bite splint is recommended for grinding at night.

Do not offer bribes, this is immoral.\nMany here come to assist as a service.\n\nYour answer is here:\n\nWhen ice melts, kinetic energy of H2O molecules is increased by absorption of heat energy from the surroundings.\n\nHowever as the kinetic energy is increased to make the molecules move freely, Hydrogen Bonding among the water molecules becomes more effective and so a particular intermolecular distance is maintained among the molecules. \n\nThis is effective upto 4C.\n\nAfter 4C the H-bonding becomes so week as against kinetic energy that free movement of molecules is no more restricted and thus abnormal behaviour of water molecules is stopped.

My only answer to this one is the fact that they get nervous. I used to have a habit of biting my nails, but soon stopped because it is gross and you can get infections from it. I don't necessarily think that people "eat" them. Chewing is maybe something they do and it is a disgusting habit. \nI know that it is most likely a nervous habit.

There are a few explanations. The first for mainly the cracking bones would be the positive feeling one mentally and physically perceives from cracking bones (technically not actually the bones). Because they associate the action with a positive feeling they do it more often.\n\nAnother comes from the stress release. In psychology there's a term called "Sublimation" in which someone will place their agression and stress into unrelated activities. This is an example in which someone might be stressed so they bite their nails or crack their fingers because they find this to be a pleasuring release of tension through the cracking sound or the light biting of the nail and removing it. \n\nAs long as people develop posotive associations with actions they'll continue to do it. At first the discovery is probably accidental but eventually a habit forms (the body seeks positive feelings and stress release).\n\nHope that helps

to keep ourselves from taking and consuming too much.

keep putting ice on it.

Before you sleep take aspirin or a pain reliever. I just put ice in my mouth and keep it near where the pain is. It usually numbs the pain, and it dissolves so there is no clean-up!

It is just like the people who order Bottled Water and a glass of ice. The ice was made with the tap water!!! \n\nBut, in all honesty, I do the same thing. I cut out all the sugary drinks from my diet and if you think about it... over the course of the day and it cut over 200 grams of carbs. \nI would rather get my carbs from food than liquid.
