What causes dentin hypersensitivity?

What causes dentin hypersensitivity?

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.

What condition precedes the development of dentinal hypersensitivity?

Recession is the initiating event that leads to exposure of the dentin layer and the development of hypersensitivity. Recession is often initiated by damaging oral hygiene practices.

Which of the following teeth are most affected by hypersensitivity?

All teeth are susceptible but canines and premolars are the most affected.

What is dentine hypersensitivity?

The condition has been defined by an international workshop on DH as follows:[8] “Dentine hypersensitivity is characterized by short, sharp pain arising from exposed dentine in response to stimuli, typically thermal, evaporative, tactile, osmotic or chemical and which cannot be ascribed to any other dental defect or …

What causes tooth sensitivity to cold?

Tooth sensitivity triggered by heat or cold tends to occur when a tooth’s outer protective layer, the enamel, has worn down. Enamel covers the parts of a tooth above the gums. A loss of enamel can expose the sensitive dentin of the tooth, the layer below the enamel that allows heat and cold to stimulate nerves.

What causes gums to recede?

Receding gums can be caused by a number of factors, including ageing, brushing too hard or even poor oral health. Poor oral health can lead to gingivitis, when the gums become inflamed due to the presence of plaque bacteria and, if left untreated, eventually begin to recede.

What is hypersensitivity teeth?

Tooth sensitivity, or “dentin hypersensitivity,” is exactly what it sounds like: pain or discomfort in the teeth as a response to certain stimuli, such as hot or cold temperatures.

What is desensitization of hypersensitive teeth?

Your dentist can apply a thin layer of a fluoride gel or another type of desensitizing agent to strengthen your enamel which will help reduce teeth sensitivity and stop the transmissions to your nerves causing pain. These appointments only take a few minutes and have long-lasting effects.

Which is the most accepted theory of dentin hypersensitivity?

Hydrodynamic Theory for sensitive dentine was first proposed by Brannstorm [21]. This theory is the most widely accepted theory for DH. The theory has been proposed based on the movement of the fluid inside the dentinal tubules.

Which is the desensitizing agent?

The “at home” desensitizing agents include toothpastes, mouthwashes or chewing gums and they act by either occluding the dentinal tubules or blocking the neural transmission. This article also discusses the recent treatment options like bioglass, Portland cement, lasers and casein phosphopeptide.

What is desensitizing agent?

Objective: Dentin desensitizing agents are used in the treatment of dentin hypersensitivity, which is defined as a painful response in the exposed dentin to stimuli that are thermal, evaporative, tactile, osmotic, or chemical.

What causes dentine?

Cause of Exposure: When plaque accumulates along your gingival margin, the edge of the gum that meets your teeth, the result can be gum recession (and disease). When your gums recede below your enamel layer into the root, your cementum layer will be exposed. This can lead to dentin exposure.

What helps tooth sensitivity to hot and cold?

Use toothpaste for sensitive teeth – there are many toothpastes available that are created specifically to target dental sensitivity, and ingredients in these toothpastes can significantly reduce pain when consuming hot and cold beverages and improve overall oral health.

What causes gum recession and can it be prevented?

Some of the causes of gingival recession are preventable. The most obvious, preventable cause is brushing the teeth too harshly or using a hard-bristled toothbrush. Instead, people should use a soft-bristled toothbrush and avoid over brushing, applying gentle strokes.

Can vitamin deficiency cause receding gums?

Vitamin B deficiency can cause receding gums, a sensitivity of mucous membranes, and toothaches. Vitamin B improves general oral health, prevents canker sores, and reduces tongue inflammation.

What causes tooth sensitivity to hot and cold?
