Overview
Dentin hypersensitivity (DH), also known as tooth sensitivity, is a prevalent clinical condition characterized by sharp, transient pain arising from exposed dentin in response to stimuli such as thermal changes, osmotic pressure, or chemical exposure. This condition significantly impacts patient quality of life, often leading to discomfort and avoidance of certain foods and activities. It predominantly affects adults, particularly those aged 20 to 50, with prevalence rates reaching up to 98% in some populations 13. Understanding and managing DH is crucial in day-to-day dental practice to alleviate patient discomfort and improve oral health outcomes.Pathophysiology
Dentin hypersensitivity arises primarily due to the exposure of dentinal tubules, which are normally covered by enamel and cementum. Etiological factors such as abrasion, erosion, and attrition progressively degrade these protective layers, exposing the dentin to external stimuli 12. According to Brännström’s hydrodynamic theory, when these tubules are exposed, stimuli like temperature changes or osmotic pressure induce fluid movement within the tubules 45. This fluid movement creates pressure changes that activate mechanoreceptors at the pulp-dentin border, leading to pain signals 412. The patency and diameter of dentinal tubules play a critical role; sensitive teeth often exhibit more patent tubules with larger diameters compared to non-sensitive teeth 35. Effective management strategies aim to either reduce nerve excitability or occlude these tubules, thereby interrupting the pain pathway 134.Epidemiology
The prevalence of dentin hypersensitivity varies widely across studies but generally ranges from 3% to 98% globally 138. It is particularly common in adults aged 20 to 50, with higher incidences noted in individuals with periodontal diseases, gingival recession, and those who have undergone extensive dental procedures 38. Geographic and demographic factors can influence prevalence, though specific trends over time are less consistently reported. Risk factors include mechanical wear (abrasion), chemical dissolution (erosion), and tooth-to-tooth contact (attrition), which collectively contribute to the progressive exposure of dentin tubules 12.Clinical Presentation
Patients typically present with sharp, localized pain that is transient and triggered by stimuli such as cold air, sweet foods, acidic beverages, or tactile pressure 24. The pain is often described as sudden and intense, lasting only a few seconds. While thermal stimuli (e.g., cold) are common triggers, chemical stimuli like acidic foods can also provoke symptoms 26. Atypical presentations may include chronic discomfort or pain that lingers longer than expected, which could indicate underlying pathology requiring further investigation 24. Red-flag features include persistent pain not relieved by desensitizing treatments, swelling, or signs of infection, necessitating referral for further diagnostic workup 24.Diagnosis
Diagnosis of dentin hypersensitivity involves a thorough clinical history and examination to exclude other dental conditions such as caries, cracked teeth, or pulpitis. Key diagnostic criteria include:Specific Tests and Criteria:

Prognosis & Follow-Up
The prognosis for dentin hypersensitivity is generally good with appropriate management, often leading to significant symptom relief. Prognostic indicators include:Follow-Up Recommendations:
Special Populations
Pediatrics
Children with dentin hypersensitivity may require gentler desensitizing agents and parental guidance on oral hygiene practices 10.Recommendations:
Elderly
Elderly patients may have more complex dental conditions; careful assessment and conservative treatments are advised 10.Recommendations:
Periodontal Disease Patients
Patients with periodontal disease often have increased sensitivity due to gingival recession and enamel wear 8.Recommendations:
