Oral composition is the study of the framework of the teeth and their bordering frameworks. The teeth are an fundamental part of the body and play a crucial role in chewing, attacking food, and grinding. They also contribute in speech and the overall look of the face.

There are several kinds of teeth in the human mouth, each with its own specific function. The incisors are the sharp, chisel-shaped teeth located at the front of the mouth. They are used for reducing and attacking off small items of food. 

The canines, also known as the cuspids, are the pointed teeth located alongside the incisors. They are used for tearing and grasping food The premolars, also known as bicuspids, are the teeth located behind the canines.They are used for squashing food and grinding.

The molars, located at the rear of the mouth, are the biggest teeth and are used for grinding and squashing food right into smaller sized items.The teeth are comprised of several various components. The crown is the noticeable part of the tooth that's over the periodontal line. The origin is the component of the tooth that's embedded in the jawbone. 

The enamel is the hard, white external layer of the tooth that secures the within the tooth from degeneration. The dentin is the layer underneath the enamel that's softer and more yellow in color. The pulp is the soft cells inside the tooth which contains capillary and nerves.

The teeth are held in position by the gum tissues, which are the soft cells that border the teeth and hold them in position. The gum tissues are comprised of several various layers, consisting of the gingiva, the connective cells, and the periodontal tendon. The gingiva is the noticeable part of the gum tissues, and the connective cells and periodontal tendon help to hold the teeth in position.

Along with the teeth and gum tissues, there are several various other frameworks in the mouth that are necessary for oral composition. The tongue is a muscle body organ that helps to move food about in the mouth and aids in talking and ingesting. The salivary glands produce saliva, which helps to moisten and soften food in the mouth. The lips and cheeks help to maintain food in the mouth and aid when chewing.

Overall, oral composition is an important area of study that helps us understand the framework and function of the teeth and the various other frameworks in the mouth. Understanding oral composition is crucial for preserving excellent dental wellness and preventing oral problems such as periodontal condition and tooth dental caries.

There are several various other important frameworks in the mouth relates to oral composition. The palatal rugae, also known as the ridges on the roofing of the mouth, help to maintain food in position while chewing. The frenulum, a small fold of skin located under the tongue, helps to support the tongue to the flooring of the mouth. The uvula, a small, fleshy protrusion at the rear of the mouth, helps to maintain food and fluids from getting in the respiratory tract.

The temporomandibular joint (TMJ) is the joint that connects the lower jaw (mandible) to the head. It allows the jaw to move backwards and forwards and side to side, which is important for talking, chewing, and ingesting. Disorder of the TMJ can cause discomfort and problem with these tasks.

Proper oral treatment is important for preserving excellent dental wellness and preventing oral problems. This consists of cleaning and flossing regularly to remove plaque, visiting the dental professional for normal check-ups and cleanings, and following a healthy and balanced diet reduced in sugar to prevent tooth degeneration.

Oral composition is a complex area that involves the study of the framework, function, and development of the teeth and the bordering frameworks in the mouth.    Understanding oral composition is important for preserving excellent dental wellness and preventing oral problems, as well when it comes to improving overall wellness and wellness.The teeth are the hardest materials in the body. Besides being essential for chewing, the teeth play an important role in speech.

Components of the teeth consist of:

  • Enamel: The hardest, white external component of the tooth. Enamel is mainly made of calcium phosphate, a rock-hard mineral.
  • Dentin: A layer hidden the enamel. It's a difficult cells which contains tiny tubes. When the enamel is damaged, heat or cool can enter the tooth through these courses and cause level of sensitivity or discomfort.
  • Pulp: The softer, living internal framework of teeth. Capillary and nerves go through the pulp of the teeth.
  • Cementum: A layer of connective cells that binds the origins of the teeth securely to the jawbone and gum tissues.
  • Periodontal tendon: Cells that helps hold the teeth securely versus the jaw.

  • Incisors (8 total): The middlemost 4 teeth on the lower jaws and top.
  • Canines (4 total): The pointed teeth simply outside the incisors.
  • Premolars (8 total): Teeth in between the molars and canines.
  • Molars (8 total): Level teeth in the back of the mouth, best at grinding food.
  • Knowledge teeth or 3rd molars (4 total):These teeth erupt at about age 18, but are often surgically removed to prevent variation of various other teeth.

The crown of each tooth jobs right into the mouth. The origin of each tooth descends listed below the periodontal line, right into the jaw.

Teeth Problems

  • Cavities (caries):  Microorganisms evade elimination by cleaning and saliva and damage the enamel and deeper frameworks of teeth. Most tooth dental caries occur on premolars and molars.
  • Tooth Degeneration :A basic name for condition of the teeth, consisting of tooth dental caries.
  • Periodontitis: Swelling of the deeper frameworks of the teeth (periodontal tendon, jawbone, and cementum). Inadequate dental health is usually at fault.
  • Gingivitis: Swelling of the surface part of the gum tissues, about and in between the crowns of the teeth. Plaque and tartar accumulation can lead to gingivitis.
  • Plaque: A sticky, anemic movie made of microorganisms and the materials they secrete. Plaque establishes quickly on teeth after consuming sweet food, but can be easily combed off.
  • Tartar: Ifplaque isn't removed, it blends with minerals to become tartar, a more challenging material. Tartar requires professional cleaning for elimination.
  • Overbite: The top teeth protrude significantly over the lower teeth.
  • Underbite: The lower teeth protrude significantly previous the top teeth.
  • Teeth grinding (bruxism): Stress, stress and anxiousness, or rest problems can cause teeth grinding, usually throughout rest. A boring migraine or aching jaw can be signs and symptoms.
  • Tooth level of sensitivity: When several teeth become conscious warm or cool, it may suggest the dentin is revealed.

Teeth Tests

  • Teeth X-ray movies:X-ray images of the teeth may find tooth dental caries listed below the periodontal line, or that are too small to determine or else.
  • Teeth assessment: By viewing and delicately manipulating the teeth, a dental practitioner can find potential teeth problems.
Teeth Therapies
  • Cleaning teeth: Everyday cleaning of the teeth eliminates plaque and helps prevent tooth dental caries.
  • Flossing teeth: Using floss or an authorized oral periodontal cleanser cleanses teeth listed below the periodontal line, where cleaning cannot get to.
  • Washing teeth: Washing everyday with an antibacterial mouthwash eliminates microorganisms that cause bad periodontal condition and breath.
  • Teeth cleaning: Professional teeth cleaning every 6 months may help prevent periodontal condition and teeth.
  • Tooth filling: Drilling out the unhealthy component of a tooth and packing the space with a mineral filling can prevent a cavity from damaging the tooth.
  • Origin canal: The deep pulp of a tooth is pierced out, filled, and cleaned. An origin canal is done when damage to the teeth has affected the deep pulp.
  • Tooth removal: If a tooth is too damaged to repair with a filling or origin canal, it may be removed. Knowledge teeth are often removed to prevent variation of the various other teeth.
  • Dental braces: A synthetic device or system that places teeth under stress for an extended period of time. Eventually, dental braces can help jagged teeth become realigned.
  • Mouth protect: A plastic mouthpiece can provide protection from teeth grinding and injury throughout sporting activities.
  • Oral sealers: A plastic sealer used to the teeth can help obstruct microorganisms from concealing in holes on teeth surface areas. Sealers can help prevent tooth dental caries.
  • Teeth bleaching: Non-prescription and professional chemical therapies can bleach teeth to a better white. Tooth level of sensitivity is one of the most common negative effects.
