What are upper teeth? Learn about the mandibular canine and mandibular first molar. Find out what function they serve. There are three types of upper teeth: incisors, canines, and molars. The function of these teeth varies. Here are some tips for identifying the type of upper tooth you have. And, as always, visit your dentist if you are unsure of what your upper teeth do.

The nerves that innervate the maxillary teeth are from the infraorbital and maxillary ganglia. The posterior superior alveolar nerve and the anterior superior alveolar nerve contribute to the drainage of the maxillary plexus. The posterior superior alveolar nerve, in turn, drains into the submandibular lymph nodes. The nerves of the upper teeth are innervated by the trigeminal nerve.
The teeth in the upper jaw, called the maxillary, are formed along the maxillary bone. They include incisors (the top incisors), premolars, and canines. Understanding the functions of these teeth is important for fighting bacteria and preventing infection of the gum tissue. These teeth have specific roles in our eating habits. As such, they act like silverware, cutting food.
The crown of the tooth, the visible part, lies above the gingiva. The color of the crown of the teeth varies according to the age of the person and the nutrition he/she receives. The teeth's roots are located in dental alveoli. The crown of the tooth connects to the root through a portion of the tooth called the neck. This neck extends about one to two millimeters above the gum.
The final section of the maxillary teeth are called molars. They are rounded and have four or five cusps. Three sets of molars are found on each side of the mouth. The first molar is located closest to the front of the mouth and is the largest of the three. The second and third molars are slightly smaller and serve the purpose of grinding food.
Transmigration of the mandibular canine is uncommon, but it is associated with other inherited dental anomalies. A defect in dental follicle metabolism misdirects the eruption path. A normal vertical eruption pathway is replaced by an apical and mesial one. Despite its rareness, it is often difficult to correct, despite extensive treatment. This article will discuss the various treatment options available for transmigration of the mandibular canine.
Treatment options for this problem vary and may include surgical exposure of the deciduous canine or orthodontic treatment to pull the canine into its correct position. The earlier this condition is diagnosed, the better the outcome. In addition to extraction, orthodontic treatment may be required to correct the space between the maxillary and lateral incisor. However, the removal of an impacted canine is not always possible.
If a mandibular canine has been transmigrated, its position in the mandibular arch is usually the cause. Transmigration occurs when the unerupted canine has traveled through the midline. If this is the case, there is enough space for the tooth to grow. Surgical extraction may be the best treatment for migrated canine, though it is not always the best option.
The mandibular canine is a member of the teeth in the lower jaw. It aids in chewing and tearing food. It erupts permanently around age nine to ten. By the age of thirteen, the mandibular canine is the longest tooth in the mouth. Its root is the longest and is narrower than the maxillary canine. It is numbered 43 in the left jaw and 33 in the right.
Mandibular first molar
The crown of the mandibular first molar is the largest of any tooth in the human mouth. It consists of four cusps, two of which are lingual, with the other two being buccal. These cusps have different heights and areas relative to each other. The occlusal view of the first molar helps us to understand their shapes.
The mandibular first molar is the most frequently affected tooth by caries, and is often the tooth that must have root canal treatment. The mandibular first molar has two roots, with a slightly widened buccolingual surface and a flat mesiodistal surface. It is generally straight, with one root positioned distolingually.
The permanent mandibular first molar is designated by a number, which is “30” on the right and “19” on the left. Surgically identifying the first molar involves using a number, paired with a symbol, to indicate the quadrant the tooth is located in. So, the left and right first molars would have the same number, “6,” and the right molar would have a ‘+' symbol on both sides.
CBCT is a diagnostic tool used to determine root canal morphology in patients with mandibular first molar. The imaging technology allows the dentist to see the root canal anatomy of multiple teeth in different situations. It can also detect root canal morphology in the presence of aberrations. For example, a single root may result in a single molar that is affected by a dental implant.
The groove pattern on the mandibular first molar is more complicated than that on the anterior molars. The mandibular second molar has a single buccal groove that separates the distobuccal from the mesiobuccal cusp. This groove often ends in a pit on the buccal surface, which can be a potential site of decay.
Function of incisors
The incisors are the flattest teeth in the mouth and are found on both sides of the upper jaw. Their main function is to cut food during occlusion, which occurs when the upper and lower jaw meet. In addition to cutting food, incisors also function as the corner teeth of the mouth, breaking down food into manageable pieces for chewing. Their shape and function vary greatly from individual to individual, but the function of all three types of incisors is similar.
The incisors are one of the four primary teeth in the human jaw. The mandibular central incisors have a pronounced cervical line and a deep, marked central groove on the distal surface. The incisal edge of the crown is perpendicular to the labiolingual axis, which is wider than the mesiodistal axis. The incisal third of the tooth crown has a concave labial surface.
The mesial surface of the maxillary central incisor has a triangular outline, with the cervical line curving less than the mesial surface. This triangular shape is more prominent from a distal perspective, as a greater portion of the labial surface is visible. In addition, the incisal surface is triangular, with a center located lingually.
The lateral incisors are vital for digestion. They help to break down food and chew it more efficiently. The canines, or cuspids, are located on both sides of the jaw and sit at the curve of the dental arch. These teeth are called cusps and are found at the top of the jaw on each side. A large portion of the canines is used for chewing food.
Function of canines
The canines are the most posterior of the teeth in the upper jaw and serve two important functions. They tear food and act as anchors when the teeth come together. The permanent upper canine erupts around age nine, while the lower canine erupts around age 11 or 12. In between canines and molars are the premolars. The premolars serve a similar function but have a more flat biting surface. They replace baby molars.
The canines are the sharpest teeth in the mouth. These teeth are first to come in between 16 and 20 months, coming in before the rest of the teeth. Eventually, they are replaced by permanent canines, which emerge between nine and twelve years. While the incisors are used to cut food, the canines have the longest roots of all teeth. They also have a single pointy cusp.
The function of canines in the upper teeth is to chew food. They are also the most prominent teeth in the mouth. They are often the largest. Some animals have more than one set of canines, which is called a canine mammal. Dogs, oxen, and sheep all have four pairs of canines. Several species of dogs also have canines. These teeth are known as cuspids.
The lower canines usually start coming in around nine years of age, and the upper canines usually come in between eleven and twelve. The lower canines, however, will come in before the upper ones. The lateral incisors are located on opposite sides of the jaw. If they are missing, eating hard food is a challenge. So, the function of canines in upper teeth is vital. So, what do these teeth do?
