One of the types is Molars divided into the upper and lower jaw. Maxillary molars are located in the upper jaw while Mandibular molars are placed in the lower jaw.
This article will discuss the two in detail including the difference between them along with the different types of teeth.
It will allow you to understand the overall context better. Our jaw has four different types of teeth namely —. Maxillary molars are the 6 molars on the maxillary upper arch or jaw. The molars have four well formed cusps, two buccal and two lingual cusps and one supplemental cusp of little practical use known as cusp of carabelli. The geometric form of the maxillary molars is a trapezoid in lingual view. They are rhomboids with 2 acute and 2 obtuse angles in occlusal view.
Your premolars are wide, uneven, and have an occlusal surface. Colloquially, it is diamond shaped with pits and trenches. Your premolars are around 0. These are transitional teeth between canines and the molar teeth. The premolars usually have two cusps and a single root. Lastly, the molars are located at the rear part of your mouth. There are eight molars in your mouth, which help in chewing, grinding, and clenching food.
The most posterior teeth in the mouth are the molars. They usually have four to five cusps, rectangular shaped with pits, and fissures on it. The occlusal surface of the molar teeth is wide and even. Various countries have their own specific numbering system. Cancellation Policy. Copyright Legel Privacy Accessibility Sitemap. Incisors Incisors are the eight teeth in the front 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 for your baby teeth, and between ages 6 and 8 for your adult set. Canines Your four canines fangs 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, with the upper canines coming in just ahead of the lower canines. In permanent teeth, the order is reversed, with lower canines erupting around age 9 and the uppers arriving between ages 11 and 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 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 Some people never develop third molars at all.
For those who do, these molars may cause crowding and need to be removed.
