Your teeth/tooth do the main jobs: Apart from been the strongest parts in the body, it serves as aesthetics purposes, helps in speech and helps you chew food.
What Are The Different Parts Of A Tooth?
Each tooth has several distinct parts; here is an overview of each part:
- Enamel – this is the physical and hardest part of the tooth that has the most mineralized tissue in the body. Teeth can be damaged by dental caries if you don’t practice good oral hygiene.
- Dentin – this is the layer of the tooth under the enamel. If dental caries goes beyond the enamel, it next affects the dentin — where a lot — if not millions of tiny tubes are located and lead directly to the dental pulp.
- Pulp – this is the soft tissue located in the center of all teeth, where the nerve tissue and blood vessels are seen or present. If cavities and tooth decay gets to the pulp, you usually feel pain and may require a root canal procedure
- Cementum: this is the layer of connective tissue that join the roots of the teeth firmly to the gums and jawbone.
- Periodontal ligament: this tissue helps to hold each tooth tightly against the jaw. A normal adult mouth has 32 teeth, which (except for wisdom teeth) have erupted by about age 13.
What are the names of each tooth?
Most adults have 32 teeth, called permanent or secondary teeth:
- 8 incisors
- 4 canines, also called cuspids
- 8 premolars, also called bicuspids
- 12 molars, including 4 wisdom teeth: These teeth erupt at around age 18, but are often surgically removed to prevent displacement of other teeth.
- 4 incisors
- 2 canines
- 4 molars
Keep reading to learn more about the different types of each tooth, including their shape and function.
What are the Four types of teeth?
- Incisors – Everyone incisors are eight in the front center of your mouth (four on both upper and lower). These are typically the first adult teeth that your child will get, coming in when your child is between six and eight years old. Incisors are the teeth you will see coming in and use to bite into your food.
- Canines – Your child’s canines are the next teeth that develop in their mouth. You have four of them and they are the sharpest one, used for tearing apart food.
- Premolars – Premolars are used for tearing and chewing food. Unlike your incisors and canines, premolars have a flat biting surface. You have eight premolars in total.
- Molars – Your molars are your largest teeth. Their function is similar to that of the premolars, to grind, tear, and chew food. Molars have a large flat biting surface which makes them perfect for all.
- Cavities (caries): Bacteria evade removal by brushing and saliva and damage the enamel and deeper structures of each tooth. Most cavities occur on molars and premolars.
- Tooth decay: A general name for the disease of the teeth, including cavities.
- Periodontitis: Inflammation of the deeper structures of each tooth (periodontal ligament, jawbone, and cementum). Poor oral hygiene is usually the cause.
- Gingivitis: Inflammation of the surface portion of the gums, around and between the crowns of the teeth. Plaque and tartar buildup can lead to gingivitis.
- Plaque: A sticky, colorless film made of bacteria and the substances they secrete. Plaque develops very fast after eating sugary food but can be easily brushed off.
- Tartar: If plaque is not removed, it mixes with minerals to become a harder substance that forms tartar. Tartar requires scaling and polishing a professional cleaning that can be performed by a dental hygienist or dentist for removal.
- Overbite: The upper teeth protrude significantly over the lower teeth.
- Underbite: The lower teeth protrude significantly past the upper teeth.
- Teeth grinding (bruxism): Stress, anxiety, or sleep disorders can cause teeth grinding, usually during sleep. A dull headache or sore jaw can be symptoms.
- Tooth sensitivity: sensitivity occur on one or more teeth as a result of exposed dentin and become sensitive to hot or cold too.
- Teeth X-ray films: The purpose of Dental X-ray films or pictures of the teeth is to detect cavities below the gum line, or that are too small to identify.
- Teeth examination: Also called oral diagnosis is by viewing and gently tapping the teeth, a dentist can detect potential teeth problems.
- Brushing teeth: Daily brushing removes plaque and helps prevent cavities.
- Flossing teeth: Using floss or an approved dental gum cleaner cleans teeth below the gum line, where brushing cannot reach.
- Rinsing teeth: Rinsing daily with an antiseptic mouthwash kills bacteria that cause bad breath and gum disease.
- Teeth cleaning: Professional teeth cleaning every six months may help prevent teeth and gum disease.
- Tooth filling: Drilling out the diseased part of a tooth and packing the space with a mineral filling can prevent a cavity from destroying the tooth.
- Root canal: The deep pulp of a tooth is drilled out, cleaned, and filled. A root canal is done when damage to the teeth has affected the deep pulp.
- Tooth extraction: If a tooth is too damaged to repair with a filling or root canal, it may be removed. Wisdom teeth are often extracted to prevent displacement of the other teeth.
- Braces: An artificial device or system that places teeth under tension for a long period of time. Eventually, braces can help crooked teeth become realigned.
- Mouth guard: A plastic mouthpiece can provide protection from teeth grinding and injury during sports.
- Dental sealants: A plastic sealant applied to each tooth can help block bacteria from hiding in crevices on each surface. Sealants can help prevent cavities.
- Teeth whitening: Over-the-counter and professional chemical treatments can bleach teeth to a brighter white. Tooth sensitivity is the most common side effect.
