Tooth hypersensitivity, or more precisely dentine sensitivity or hypersensitivity, is described clinically as an exaggerated response to painless stimuli and satisfies all the criteria to be classified as a true pain syndrome. Dentine hypersensitivity is a relatively common problem experienced in clinical dental practice.
What is the stimulus ?
The pain producing stimuli can be thermal, tactile, osmotic, chemical or evaporative but the cold stimulus appears to be the strongest and causes the greatest problem to those troubled by dentine hypersensitivity.
- This condition may disturb the patient during eating, drinking, brushing and sometimes even breathing. It is a common finding among adult population with the prevalence data ranging from 8-57%.
- People who suffer with periodontal diseases have higher chances of dentinal hypersensitivity as periodontal disease bacteria are reported to penetrate dentine to a considerable distance.
- 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 pathology. Canines and premolars are most affected
