Dentin hypersensitivity arises when tubules found within dentin become exposed, most commonly caused by gingival recession or enamel wear. Once exposed, these tubules may come into contact with stimuli such as hot, cold and sweet foods and drinks, which can induce the movement of fluid within the tubules.
Which of the following may cause dentin to become exposed?
Periodontal disease, gingival recession, cracked teeth, erosion, abrasion, abfraction and tooth fracture may cause hypersensitivity. All of these conditions result in exposed dentin, which creates an environment in which stimuli cause dentinal tubular fluid movement that activates nerve fibers, causing pain.
What cells make up dentine?
Odontoblasts form the dentine, a collagen-based mineralized tissue, through secretion of its collagenous and noncollagenous organic matrix components and by control the mineralization process. A conspicuous cell process arises from the cell body of odontoblasts and penetrates into the mineralized dentine.
Where is the dentine found?
Dentin or dentine is a layer of material that lies immediately underneath the enamel of the tooth. It is one of the four major components of the tooth which comprises: The outer hard enamel. The dentin underneath the enamel.
Can dentin repair itself?
Tooth enamel is incapable of self-repairing whereas dentin and cememtum can regenerate with limited capacity. Enamel and dentin are commonly under the attack by caries.
What is the treatment for exposed dentin?
If you’re experiencing sensitivity or pain due to exposed dentin, talk to your dentist. They may suggest treatment options that range from changing your toothpaste to using a mouthguard or even in-office procedures such as fluoride treatments and gum therapy. Choose Heritage Dental Centre for your dental care.
What are the types of dentin?
Types. There are three different types of dentin which include primary, secondary and tertiary. Secondary dentin is a layer of dentin which is produced after the tooth’s root is completely formed. Tertiary dentin is created in response to a stimulus, such the presence of tooth decay or wear.
What are the 3 theories of dentin sensitivity?
Three mechanisms, all involving an understanding of the structure of dentin and pulp, have been proposed to explain dentin sensitivity: (1) The dentin contains nerve endings that respond when it is stimulated, (2) the odontoblasts serve as receptors and are coupled to nerves in the pulp, and (3) the tubular nature of …
Is Sensodyne bad for your teeth?
Sensodyne definitely improves oral health, lowers the risk for cavities and gum disease, and reduces tooth sensitivity. It is a wonderful toothpaste for anyone to use, and it has significant benefits for those with a tendency to develop cavities or experience sensitivity. It can stop cavities in their earliest stages.
Why is my enamel wearing away?
Tooth erosion happens when acids wear away the enamel on teeth. Enamel erosion can be caused by the following: Having too many soft drinks, which have lots of phosphoric and citric acids. Bacteria in your mouth thrive on sugar, and they make acids that can eat away at enamel.
Does Sensodyne really work?
Sensodyne claims to protect sensitive teeth by repairing vulnerable spots, but does it really work? YES! Researchers in Italy recently confirmed it. The outermost layer of your teeth can wear down from mechanical factors, such as grinding or from erosive chemicals, like acids found in some foods.
Does your enamel grow back?
Once tooth enamel is damaged, it cannot be brought back. However, weakened enamel can be restored to some degree by improving its mineral content. Although toothpastes and mouthwashes can never “rebuild” teeth, they can contribute to this remineralization process.
What is dentine and its function?
Dentin reinforces the tooth’s enamel and helps to support the structure of the tooth, but it also plays an important role inside the tooth. Dentin forms the layer of the tooth that surrounds the dental pulp, the soft tissue which makes up the inside of the tooth.
Can enamel be restored?
Your body cannot make new enamel. However, you can strengthen and repair existing enamel. This happens through a process called remineralization, which naturally occurs when essential minerals like fluoride, calcium, and phosphate reunite with your enamel.
What is the first dentin formed?
Development. The formation of dentin, known as dentinogenesis, begins prior to the formation of enamel and is initiated by the odontoblasts of the pulp. Dentin is derived from the dental papilla of the tooth germ.
What is the dentin of the tooth?
Dentin. That part of the tooth that is beneath enamel and cementum. It contains microscopic tubules (small hollow tubes or canals). When dentin loses its protective covering (enamel), the tubules allow heat and cold or acidic or sticky foods to stimulate the nerves and cells inside the tooth, causing sensitivity.
What is enamel made up of?
Enamel is the hardest substance in the human body, and it covers the outer surface of your teeth. It is made mostly of an extremely hard mineral called calcium phosphate. Dentin makes up the layer just below your tooth’s enamel. It consists of living cells that secrete a mineral substance.
How do I know if dentin is exposed?
The dentin isn’t as hard as the enamel and contains nerve endings to connect to the pulp. If you begin to experience sensitivity when eating hot and cold foods or generally around the mouth, the dentin is exposed.
Does exposed dentin need to be covered?
So, if your enamel is wearing away and you have exposed dentin, it’s especially important to cover it up and prevent the excruciating pain that can come from exposed pulp.
Can you whiten tooth dentin?
The American Dental Association states that teeth can be whitened in one of two ways: using a product with a bleaching agent to penetrate the enamel and change the color of the yellowy dentin or using an abrasive treatment (which includes mouthwash, gum, or toothpaste) that removes superficial stains on top of the …
Do hairline cracks in teeth heal?
While a crack can be repaired, a cracked tooth will never be 100 percent healed, unlike a broken bone might be. But prompt treatment offers the best chance of saving your tooth and preventing infection and further damage. And while your mouth may be sore after the treatment, the pain should subside in a few days.
How do you fix enamel damage?

Can you repair damaged teeth?
Dental Filling or Bonding
If you have chipped off just a small piece of tooth enamel, your dentist may repair the damage with a filling. If the repair is to a front tooth or can be seen when you smile, your dentist will likely use a procedure called bonding, which uses a tooth-colored composite resin.
