what are the different types of teeth with their function?why it is so hard?
Answers
Answer:
Premolars Premolars, or bicuspids, are used for chewing and grinding food. Adults have four premolars on each side of their mouths — two on the upper and two on the lower jaw. There are no primary premolars; the first premolars appear around age 10, with the second premolars arriving about a year later. These take the places of the first and second primary molars (described below).
Molars Molars are also used for chewing and grinding food. Primary molars, also known as deciduous molars, appear between 12 and 28 months, and are replaced by the first and second premolars (four upper and four lower) described above.
The permanent molars (also four upper and four lower) do not replace any primary teeth, but come in behind all of them, further back in the jaw. The first permanent molars erupt at around age 6 (before the primary molars fall out), while the second molars come in between ages 11 and 13.
Third molars The third molars are commonly known as wisdom teeth. These are the last teeth to develop and don't typically erupt until age 18 to 20. Some people never develop third molars at all. For those who do, these molars may cause crowding and need to be removed. If they don't fully erupt they are said to be impacted, and are commonly removed.
Your mouth is important, so don’t take your teeth or oral health for granted. "For good dental health, brush and floss your teeth regularly, don't smoke, eat a healthy diet, and see your dentist regularly for dental cleanings and checkups," advises Lal. A healthy mouth makes for a healthy body — and a pretty smile.
Answer:
These are the four basic types of teeth. They're:
( 1 ) Incisors
( 2 ) Canines
( 3 ) Premolar
( 4 ) Molars
(1) function of incisors -- incisors are eight teeth in the front center of your mouth (four on both bottom and top). These are typically the first adult teeth that a child will get, coming in when the child is between six and eight years old. Incisors are the teeth that you use to bite into your food.
(2) function of canines -- canines are the next teeth that develop in your mouth. You have four of them and they are your sharpest teeth, used for tearing apart food.
(3) function of Premolar -- Premolars are used for tearing and crushing food. Unlike your incisors and canines, premolars have a flat biting surface. You have eight premolars in total.
(4) function of molars -- Your molars are your largest teeth. Their function is similar to that of the premolars, to grind, tear, and crush food. Molars have a large flat biting surface which makes them perfect for this job.
