Do you know tooth pulp?
Tooth pulp is soft and consists of living blood vessels, connective tissue, and large nerves. Also commonly referred to as the nerve, the pulp branches out and continues down each root through the canals of the tooth and stops just shy of the apex, or tip, of the tooth.
What are the functions of tooth pulp?
Functions of Tooth Pulp. The pulp has several important functions, including: Sensory function: Pain from trauma to the dentin and/or pulp, differences in temperature, and pressure are caused by stimulation of the pulp. Formation of dentin: The pulp is responsible for the formation of dentin.
What is the role of pulp in tooth?
The Role of Dentin. The most important job of tooth pulp is to produce dentin, which is a calcified tissue that serves as the second layer of the tooth, supporting the enamel above it. 2 Dentin is located directly above the pulp chamber, so if your tooth enamel or your gums erode, the dentin becomes exposed.
Why does my tooth swell?
If there is swelling, then it is caused by a periapical problem in the tooth associated with irreversible pulpitis or necrosis of the pulp. Irreversible pulpitis: If your tooth pulp is severely damaged, the only options are for your dentist to perform either a root canal in which the pulp is removed from your tooth, ...
What is the pulp chamber?
The shape of a pulp chamber varies based on the size of the tooth itself. Tooth pulp is soft and consists of living blood vessels, connective tissue, and large nerves. Also commonly referred to as the nerve, the pulp branches out and continues down each root through the canals of the tooth and stops just shy of the apex, or tip, of the tooth.
What is the pulp responsible for?
Formation of dentin: The pulp is responsible for the formation of dentin. In response to trauma, the pulp forms secondary dentin, also known as reparative dentin. Nourishment: The pulp contains blood vessels that keep blood flowing to help to prevent the tooth from becoming brittle by keeping it moisturized and nourished.
How many pulp organs are there in the human body?
You can have up to 52 total different pulp organs: 32 of the pulp organs can be found in your permanent teeth and 20 can be found in your primary teeth, also known as baby teeth. 1 The pulp found in primary teeth is lost along with the teeth when they fall out or are removed from your mouth. Illustration by Brianna Gilmartin, Verywell.
Can pulpitis be reversible?
Tooth decay is the number one cause of pulpitis, followed by injury. 3 If the inflammation is mild, it may be reversible, but if it's severe, the pulp can die. Pulpitis can also cause an infection at the root of your tooth, known as an abscess.
What do teeth do?
Our teeth have many functions. They bite food and start the digestive process. They tell us if something is too hot or too cold. They allow us to form sounds specific to our speech. They protect us and enhance our appearance. Our teeth are alive; the “heart” of our tooth is the dental pulp.
What is the outer lining of the root of your tooth that covers the dentin?
The cementum is the outer lining of the root of your tooth that covers the dentin.
What happens if you have a crack in your tooth?
If decay, a crack or a dental instrument invades the pulp chamber the tissue will die. Root canal therapy will save the tooth and prevent any discomfort from occurring.
Why is my pulp inflamed?
While the pulp is inflamed it will be hyper-sensitive to outside stimuli like heat, cold, and pressure .
Where is the pulp chamber?
It contains a gelatinous material known as the pulp. The chamber lies in the crown of the teeth. As the chamber extends down into the roots, it is referred to as the root canals. Depending on the anatomy of the tooth (how many roots) will affect the shape and the number of canals.
Which organelle is responsible for the formation of new dentin?
Formation of new dentin via the odontoblasts. This is the most important function of the pulp
The role of dentin
The most vital task of tooth pulp is to generate dentin, a calcified tissue that makes up the second layer of the tooth to support the enamel (first layer). The dentin is positioned right before the pulp chamber, which means if the tooth enamel deteriorates, the dentin will be exposed.
Pulpitis
This condition is the painful irritation of the pulp. Major causes of pulpitis are tooth decay and injury. If the irritation is minor, it can still be reversed, but in severe cases, the pulp may suffer necrosis. Pulpitis can also lead to infection of the tooth root, otherwise called an abscess.
Types of pulpitis
Reversible pulpitis: If the condition is reversible, the endodontist will clean up the decay or cavity and fill your teeth to alleviate the pain and inflammation.
What is the pulp of a tooth made of?
The pulp is the part in the center of a tooth made up of living connective tissue and cells called odontoblasts. The pulp is a part of the dentin–pulp complex (endodontium).
Why is pulp similar to dentin?
The pulp has a background similar to that of dentin because both are derived from the dental papilla of the tooth germ. During odontogenesis, when the dentin forms around the dental papilla, the innermost tissue is considered pulp.
How is pulpitis differentiated from other conditions?
Irreversible and reversible pulpitis are differentiated from each other based on the various pain responses that they have to thermal stimulation. If the condition is reversible then the pulp's pain response will last momentarily upon exposure to cold or hot substances; a few seconds. However, if the pain lingers from minutes to hours, then the condition is irreversible. This is a common presenting complaint that facilitates diagnoses before further investigations e.g. sensibility tests and peri-apical radiographs are proceeded.
Which plexus is separated from the odontoblasts?
They branch to form the subodontoblastic nerve plexus of Raschkow which is separated from the odontoblasts by a cell-free zone of Weil, therefore this plexus lies between the cell free and cell rich zones of the pulp. Legend: 1 - Odontoblast layer; 2 - Cell-free zone of Weil; 3 - Cell-rich zone; 4 - Pulp core.
Why do teeth have pulp necrosis?
It is often subsequent to chronic pulpitis. Teeth with pulp necrosis will need to undergo root canal treatment or extraction to prevent further spread of infection which may lead to an abscess.
Which nerve is responsible for tooth pain?
As the dental pulp is a highly vascularised and innervated region of the tooth, it is the site of origin for most pain-related sensations. The dental pulp nerve is innervated by one of the Trigeminal nerves, otherwise known as the fifth cranial nerve. The neurons enter the pulp cavity through the apical foramen and branch off to form the nerve plexus of Raschkow (as mentioned earlier). Nerves from the plexus of Raschkow give branches to form a marginal plexus around the odontoblasts, with some nerves penetrating the dentinal tubules.
Where are the radicular pulp canals?
Radicular pulp canals extend down from the cervical region of the crown to the root apex. They are not always straight but vary in shape, size, and number. They are continuous with the periapical tissues through the apical foramen or foramina.
Composition of The Tooth
- Enamel
The enamel is a thin, hard (hardest substance in our body) outer layer. It breaks down food and provides protection. It is the esthetic component of our smile. - Dentin
Dentin is the largest part of the tooth composing 60% of tooth structure. It absorbs pressure and supports the enamel. It is softer than the enamel.
Composition of The Pulp of The Tooth
- The pulp itself is composed of connective tissue, nerves, and blood vessels. The pulp interfaces with the dentin. Most of the outer part of the pulp that reaches the dentin is composed of columnar cells, called Odontoblasts. These cells produce tubules that run from the outer part of the enamel all the way into the pulp tissue. The next layer is called the cell-free zone, also know…
Functions of The Pulp
- Formation of new dentin via the odontoblasts. This is the most important function of the pulp
- Nutrition of the dentin
- Innervation of the tooth, feeling.
- Acts as a defensive mechanism as to what is entering our mouths
Diseases of The Pulp
- Dental Pulp Calcification
Pulp stones appear in the organic tissue prohibiting proper nutrients from reaching the cells of the pulp. This problem is solved with Root Canal Therapy. - Pulp Exposure
If decay, a crack or a dental instrument invades the pulp chamber the tissue will die. Root canal therapy will save the tooth and prevent any discomfort from occurring.
Prevention of Pulp Disease
- Home care-brushing twice a day with a soft bristle brush for two minutes
- Flossing at least once a day before bedtime
- Using a soft non-abrasive fluoride toothpaste
- Diet very low in sugar
