Your eight incisor teeth are located in the front part of your mouth. You have four of them in your upper jaw and four in your lower jaw. Incisors are shaped like small chisels. They have sharp edges that help you bite into food.
Adult tooth numbering system
The last tooth in the mouth, the 3rd molar, numbered 8 is what is otherwise known as the wisdom teeth.
Wisdom teeth (eights) develop as third molars usually between the age of 17 and 25, while in some people it may take up to the age of 40 or they may not appear at all. Wisdom teeth cause a lot of pain when they start to grow and may also cause malocclusion.
A normal adult mouth has 32 teeth, which (except for wisdom teeth) have erupted by about age 13: • Incisors (8 total): The middlemost four teeth on the upper and lower jaws. • Canines (4 total): The pointed teeth just outside the incisors.
How many teeth do we have, and what are their different types and functions? The permanent dentition consists of 32 teeth. This is made up of four incisors, two canines (or cuspids), four premolars (or bicuspids), four molars and two wisdom teeth (also called third molars) in each jaw.
How Many Teeth Do Kids Lose? Once your child is around the age of 13, they should have lost all twenty of their baby teeth and have them replaced by 28, new permanent teeth.
Number 8: Central incisor (upper right) Number 9: Central incisor (upper left) Number 10: Lateral incisor (upper left) Number 11: Cuspid (canine/eye tooth)
They are flat with a thin edge. They are also called anterior teeth. Both children and adults have eight incisors — four central incisors at the front of the mouth, two on each row, with one lateral incisor positioned on either side of them.
Teeth numbers 14 and 15 are your upper left molars.
Wisdom teeth, on the other hand, connect to the central nervous system, heart, liver, and intestines. They can also signal high blood pressure, eczema, headache, liver disease, pain in the extremities, and cardiovascular disease.
What age do females get wisdom teeth?

On the upper jaw, canines are also named "eye teeth" because the long root almost points to the eye socket. The canines are #6 and #11 (upper jaw) and #22 and #27 (lower jaw). Canine teeth are relatively long and pointed, used primarily for holding food while it is being ripped in the mouth.
This means a 14-year-old child should have 28 teeth, or spaces for them. Between 16 and 22 years, the 4 third permanent molars grow in. This means that an adult usually has a total of 32 permanent teeth: 16 on top and 16 on the bottom.

Over your lifetime, you will have five different types of teeth that will erupt in your mouth; incisors, canines, premolars, molars, and third molars.
Specifically, wisdom teeth. Your mouth goes through many changes in your lifetime. One major dental milestone that usually takes place between the ages of 17 and 21 is the appearance of your third molars. Historically, these teeth have been called wisdom teeth because they come through at a more mature age.
So while permanent tooth loss can occur at any age as an adult, significant averages in partial and total tooth loss tend to occur in people aged 50 years old and above.
Between the ages of about 6 and 7 years, the primary teeth start to shed and the permanent teeth begin to come through. By the age of about 21 years, the average person has 32 permanent teeth – 16 in the upper jaw and 16 in the lower jaw.
What age do people lose teeth?
All four center teeth, known as bottom and top incisors, usually fall out in the 6-8 year range. The sharp teeth beside them (called canines or cuspids) as well as the first molars leave a little later, around 9-12 years old. The second molars are often the last to go … typically in the 10-12 year range.
Incisors. – The four front teeth in both the upper and lower jaws are called incisors. Their primary function is to cut food. The two incisors on either side of the midline are known as central incisors. The two adjacent teeth to the central incisors are known as the lateral incisors.
Even at age 18, a patient may still be maturing, meaning the jaw may continue to grow and change. Rather than risk treatment failure, it's best for patients who are missing teeth and are at least 18 years old meet with their dentist for a full assessment of their situation.
ADA Universal Numbering System
Teeth numbers 1 – 16 are on your upper jaw and teeth numbers 17 – 32 are in your lower jaw. For instance, teeth numbers 1, 16, 17, and 32 are your wisdom teeth and teeth numbers 14 and 15 are your upper left molars.
Numbering starts on the top right side of the mouth with tooth number 1. It continues along the top arch and ends with tooth number 16 as the last tooth on the top left. Counting then continues on the bottom arch with the tooth farthest back on the left side as tooth number 17.
Wisdom teeth are the last adult teeth to come into the mouth (erupt). Most people have four wisdom teeth at the back of the mouth — two on the top, two on the bottom.
The upper left quadrant's incisors are 21 and 22. Your canine teeth are 13 and 23. Your premolars are numbered as 14, 15, 24, 25 and your molars are 16-18 and 26-28.
The upper teeth are numbered from 1-16 from right to left and the lower teeth are numbered 17-32 from left to right. Therefore, 1,16,17 and 32 would refer to your wisdom teeth and 6-11 and 22-26 would be your anterior teeth in the upper and lower jaws respectively. Similarly, 6,11 22, 27 would be the canines and so on.
Code 0 – Healthy gums, no bleeding when probed, no calculus or gingival pockets under 3.5mm. Code 1 – Slight bleeding when probed, no calculus or gingival pockets under 3.5mm. Code 2 – Slight bleeding when probed, Calculus or Plaque present and gingival pockets under 3.5mm.
At the very front of the mouth, the top four and bottom four teeth are the incisors. The middle ones are central incisors, while the ones on the sides are lateral incisors. Incisors are built for slicing.
Why are incisors called incisors?
Incisors (from Latin incidere, "to cut") are the front teeth present in most mammals. They are located in the premaxilla above and on the mandible below. Humans have a total of eight (two on each side, top and bottom).
They are called canines due to their resemblance to a dog's fangs. While our canine teeth aren't as long, pronounced or sharp as a dog's, they are usually longer and more pointed than our other human teeth. Canines are sometimes referred to as eye teeth because of their alignment under the eyes.
