A short-lasting, sharp pain in response to a stimulus, such as cold, hot, pressure or sweet food, affecting a tooth's surface resulting from exposed dentin.

Stimulus triggers exposed dentin's nerve endings causing a quick, sharp pain that quickly resolves if the stimulus is removed.

Short duration, rapid onset, sharp pain, quick resolution (no side effects like redness or swelling) upon removing the stimulus.

A tooth that is more prone to hypersensitivity due to exposed dentin following factors like tooth wear or gum recession.

Factors that make a tooth susceptible to dentin hypersensitivity, such as tooth wear and gum recession.

Tiny tubes within dentin that connect to the pulp.

Theory that suggests dentinal fluid movement causes pain.

Movement of fluid from high to low concentration through a semi-permeable membrane.

Dentine that is no longer covered by enamel or cementum.

Loss of gum tissue around the teeth.

Chemical, temperature, or mechanical forces that induce dentin pain.

Dentin hypersensitivity resulting from gum recession and cementum loss.

A sharp, short-lasting pain in a tooth triggered by stimuli like cold, hot, pressure, or sweet foods. It occurs when the dentin, the layer beneath the enamel, is exposed.

A clinical examination is used to identify and pinpoint the specific tooth or area of sensitivity. This involves checking tooth morphology and probing for any dentin exposure.

Dental hygienists play a crucial role in managing dentine hypersensitivity. They identify the cause, educate patients about the issue, offer preventative advice, and manage the condition.

Patients can manage dentine hypersensitivity at home by avoiding stimuli that trigger pain and using desensitizing products.

These are the ways desensitizing agents work: Occluding (blocking) the dentin tubules, preventing further exposure, and desensitizing the nerves.

Examples include calcium phosphate silicate, calcium triphosphate, bioactive glass, strontium chloride/acetate, fluoride, and arginine.

Maintaining proper oral hygiene helps prevent dentin hypersensitivity by reducing factors like tooth wear and gum recession.

Depending on the severity and cause, the treatment could include dental hygiene management, referral to a general dentist, or no action required.

Chemical ions used to block tubules dissolve, are mechanically removed, or need to form a precipitate to be effective. These methods offer only temporary solutions.

Use proteins that allow chemical ions to stick to the tooth surface (e.g., arginine), use chemicals that precipitate in an acidic environment (e.g., bioactive glass), use higher concentrations of fluoride, and promote continuous daily use for long-lasting benefits. Spitting instead of rinsing helps keep chemicals close to the tooth surface.

It increases the potassium ion concentration around the intradental nerves. This depolarizes the nerve fiber membrane, initially causing action potentials, but ultimately leads to a sustained depolarized state, inactivating the action potential, reducing pain.

Treatments range from simple, at-home solutions like toothpaste with potassium nitrate or fluoride to more complex, professional procedures.

Fluoride helps block dentinal tubules by forming calcium-phosphorous precipitates, as well as calcium fluoride and fluorapatite, which effectively block the tubules.

Dentine hypersensitivity often arises from exposed dentin due to factors such as tooth wear, gum recession, or tooth decay.

Popular brands like Colgate and Sensodyne offer toothpaste options containing arginine or stannous fluoride to occlude tubules, while fluoride itself is also known to reduce sensitivity.
