What is the other name for premolars?
Premolars are also known as "bicuspids". They are located between the molars and canines and are used for chewing and grinding food. They have two cusps one on each side making them easier to identify. Premolars typically come in two varieties the first premolar (also known as the "six-year molar") and the second premolar (also known as the "twelve-year molar"). The main distinguishing features of premolars are: Two cusps Located between the molars and canines Used for chewing and grinding foodThe main types of premolars are: First premolar (also known as the "six-year molar") Second premolar (also known as the "twelve-year molar")Premolars are an important part of the dental anatomy and are essential for proper chewing and grinding of food.
Do all your molars fall out?
The premolars are teeth located between the molars and canine teeth. There are eight premolars, two in each quadrant. The first set of premolar teeth fall out and are replaced by permanent teeth.
is a bicuspid a tooth?
Bicuspid teeth are first and second premolars. They are located between canine and first molars. They have at least two cusps. Bicuspid from Latin mean: bi- two;cuspis - sharp point.
What type of tooth is absent in a set of milk teeth?
Deciduous teeth consist of 20 teeth, : central incisor, lateral incisor and canine (A,B,C) and 1st and 2nd molar (D,E). But there are no premolars (formerly known as bicuspids) or 3rd molars (the late teeth commonly known as wisdom teeth).
Will premolar teeth fall out?
No, they do not fall out like the original baby teeth. As the jaw grows, these molars and another set (Wisdom teeth) grow in. They are usually the first teeth to get cavities since they have deep ridges.
What teeth are there in you're mouth?
There are a total of 32 adult teeth or Permanent teeth and 20 baby teeth or Primary teeth. Of the 32 permanent teeth there are: 4 third molars or wisdom teeth, 4 second molars or 12-year molars, 4 first molars or six-year molars, 4 second premolars or second bicuspids, 4 first premolars or first bicuspids, 4 canines or cuspids, 4 lateral incisors, and 4 central incisors. One of each type of tooth is present on both the left and right side of the lower jaw called the mandible, and one of each types of tooth is also present on both the left and right side of the upper jaw called the maxilla. From the back of the mouth to the midline (meaning between the two front teeth) the order of teeth are 3rd molar, 2nd molar, 1st molar, 2nd premolar, 1st premolar, canine, lateral incisor, and central incisor. Most people develop 32 teeth, however a large number of people never develop some or all of the wisdom teeth. This is not including when wisdom teeth don't erupt and remain underneath the gum and/or jaw bone. The 20 primary teeth consist of both types of incisors (8), cuspids (4), and only first and second molars (8). There are no primary premolars or primary third molars. The primary teeth are replaced by the permanent incisors, cuspids, and premolars which erupt from underneath the primary teeth. During the usual course of development, the permanent molars erupt behind the primary teeth and therefore will not erupt from beneath any primary teeth.
Do deer have a set of baby teeth?
Yes, cervids have a set of deciduous ('milk') teeth before their permanent teeth erupt. The upper teeth are first composed of a second, a third and a fourth premolar. They are then substituted by a permanent second, third and fourth premolars and molars 1, 2 and 3. They also develop two canines on the upper part. In the lower part, a deciduous second, third and fourth premolars are subistuted by permanent second, third and fourth premolars, a first, second and third molars. They also shed deciduous incisors one, two and three as well as a canine, and are then subsistuted by permanent ones. A good book on the matter is 'Teeth' by Simon Hillson (first and second editions) published by Cambridge University Press.
What are the four different kind of teeth in your mouth?
Teeth help you chew your food, making it easier to digest. Each type of tooth has a slightly different shape and performs a different job. Types of teeth include:Incisors. Incisors are the eight teeth in the front and center of your mouth (four on top and four on bottom). These are the teeth that you use to take bites of your food. Incisors are usually the first teeth to erupt, at around 6 months of age for your first set of teeth, and between 6 and 8 years of age for your adult set.Canines. Your four canines are the next type of teeth to develop. These are your sharpest teeth and are used for ripping and tearing food apart. Primary canines generally appear between 16 and 20 months of age with the upper canines coming in just ahead of the lower canines. In permanent teeth, the order is reversed. Lower canines erupt around age 9 with the uppers arriving between 11 and 12 years of age.Premolars. Premolars, or bicuspids, are used for chewing and grinding food. You have four premolars on each side of your mouth, two on the upper and two on the lower jaw. The first premolars appear around age 10 and the second premolars arrive about a year later.Molars. Primary molars are also used for chewing and grinding food. These appear between 12 and 15 months of age. These molars are replaced by the first and second permanent molars (four upper and four lower). The first molars erupt around 6 years of age while the second molars come in between 11 and 13 years of age.Third molars. Third molars are commonly known as wisdom teeth. These are the last teeth to develop and do not typically erupt until age 18 to 20, and some people never develop third molars at all. For those who do, these molars may cause crowding and need to be removed.Your mouth is important. 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. A healthy mouth makes for a healthy body ... and a pretty smile.Source: http://www.everydayhealth.com/dental-health/101/your-mouth-101.aspx
What are the names of all the teeth in your mouth?
Incisors * Maxillary central incisor * Maxillary lateral incisor * Mandibular central incisor * Mandibular lateral incisor Canines * Maxillary canine * Mandibular canine Premolars * Maxillary first premolar * Maxillary second premolar * Mandibular first premolar * Mandibular second premolar Molars * Maxillary first molar * Maxillary second molar * Maxillary third molar * Mandibular first molar * Mandibular second molar * Mandibular third molar
What is the part of the tooth that anchors it in the jaw?
If you look at a picture of a tooth, you will see the crown of the tooth. That is the top part that is above your gum. The root(s) are the anchors. Some teeth have one root and some have a few. Easy chart I found online: Laterals have one root (these are your front teeth) Canines and most premolars, except for maxillary (upper) first premolars, usually have one root. Maxillary (upper) first premolars and mandibular (lower) molars usually have two roots. Maxillary (upper) molars usually have three roots.
What nerve supplies the maxillary first and second premolars?

What is the name of the sharp molars that felines have?
The sharp fangs in an animal's mouth are all called canine teeth. The names of the teeth are incisors for cutting and snipping, canines for ripping and puncturing, premolars and molars for grinding and crushing. Felines and humans both have canine teeth. It would be too confusing to call them feline teeth in a cat and homo teeth in a human, so we call them all the name we first thought of by studying dogs - canine.
