What causes dentine hypersensitivity?
The hydrodynamic theory of dentine hypersensitivity
Brännström’s hydrodynamic theory is currently the most commonly accepted theory of how dentine hypersensitivity arises:1–4
- Dentine hypersensitivity arises when tubules found within dentine become exposed, most commonly caused by gingival recession or enamel wear
- Once exposed, these tubules may come into contact with stimuli, which can induce the movement of fluid within the tubules
- Such movement within the pulp may induce a short, sharp sensation
