Tooth sensitivity arises from fluid movement in dentinal tubules activating nerves. Treatments focus on blocking tubules or reducing nerve excitability based on the cause.

Area of Science:

  • Dentistry
  • Dental Physiology

Background:

  • Tooth sensitivity is a prevalent clinical issue.
  • Exposed dentin, despite lacking nerve endings, can be sensitive.
  • Fluid movement within dentinal tubules is a key factor in sensitivity.

Purpose of the Study:

  • To explain the mechanism of tooth sensitivity.
  • To outline therapeutic strategies for managing tooth sensitivity.

Main Methods:

  • Review of experimental evidence on dentin sensitivity.
  • Analysis of factors influencing intradental nerve activation.

Main Results:

  • Stimuli like air blasts or probing cause fluid movement in dentinal tubules.
  • This fluid movement activates intradental nerves, leading to sensitivity.

  • Dentin surface condition and pulp environment significantly impact sensitivity.

    • Conclusions:

    • Tooth sensitivity is mediated by fluid dynamics in dentinal tubules and nerve excitability.
    • Treatment approaches involve occluding dentinal tubules or modulating nerve excitability.
    • Personalized treatment is essential, considering the specific cause and extent of dentinal damage.
