1) How many teeth does an average adult have?
An average adult has 28 teeth, assuming wisdom teeth have been removed.
2) Why do we lose our first set of teeth?
The roots of our first set of teeth provide an opening for the permanent teeth to break through. The smaller, first set of teeth are needed to chew food and for proper speech development. They start to develop during pregnancy when the embryo is about six weeks old.
3) What are teeth made of?
The four major tissues that make up a tooth are enamel, dentin, cementum, and dental pulp.
4) How can we tell if we have a cavity?
Initially, you cannot tell if you have a cavity and that is the reason you need to see your dentist every six months. Cavities left untreated lead to pain and sensitivity to hot and cold
5) Why do our teeth get cavities?
Bacteria in your mouth produce acid that breaks down the enamel and dentin and produces holes in your teeth. This damages your tooth structure.
6) What makes teeth sensitive to hot and cold?
Teeth become sensitive to hot and cold when the nerves inside the dentin are exposed to the oral environment. There are several factors that contribute to this such as worn or decayed teeth or exposed roots from gum recession.
7) What is enamel?
Enamel is 96% mineral, and the remaining 4% is water and organic material.
8) What are wisdom teeth? Why do we have wisdom teeth? And why do some people need their wisdom teeth removed?
Wisdom teeth are your third set of molars. They are called wisdom teeth because they usually appear between 17-21 years of age when it is assumed that you are old enough to have some wisdom. Wisdom teeth, like all other molars, are used for grinding food. Some people need their wisdom teeth removed because they come in sideways affecting other teeth. It is common for wisdom teeth to fail to erupt completely through the gum tissue, and this is called an impacted tooth.
9) What causes teeth to discolor?
As a person ages, the mineral structure of the teeth change and teeth become darker as enamel becomes less porous. Additionally, teeth are stained from food, tobacco products, bacterial pigments and certain antibiotics (such as tetracycline).
10) Are crooked teeth genetic?
Crooked teeth can be genetic but they also can result from other factors such as thumb sucking and tongue thrusting.
