Understanding Tooth Sensitivity: Causes and Solutions
August 22ND, 2025

Dentinal hypersensitivity—commonly known as tooth sensitivity—is a prevalent oral health condition affecting millions of individuals worldwide. At Marinaside Dental in Yaletown, many patients ask, “Why do my teeth feel sensitive?” Whether triggered by cold beverages, sweet foods, or even exposure to cool air, sensitivity can cause sharp, transient pain that disrupts daily comfort.
In this article, our dental professionals explain the etiology, management, and prevention of dentinal hypersensitivity to help you protect your oral health.
What Causes Tooth Sensitivity?
Tooth sensitivity typically occurs when dentin, the layer beneath the enamel, becomes exposed—allowing stimuli to reach the dental pulp through microscopic tubules. Common etiologic factors include:
- Enamel erosion due to aggressive tooth brushing or use of highly abrasive dentifrices.
- Gingival recession, which exposes the cervical areas and root surfaces of teeth.
- Dental caries or fractured teeth, leaving dentin or pulp tissue unprotected.
- Bruxism (tooth grinding), leading to attrition and loss of enamel integrity.
- Post-operative sensitivity following dental procedures such as whitening, restorative fillings, or periodontal therapy.
Clinical Tip from our Yaletown Dentist: Use a soft-bristled toothbrush and employ gentle, circular brushing motions to preserve enamel and prevent further dentin exposure.
Treatment and Management of Tooth Sensitivity
At Marinaside Dental, we develop individualized treatment plans to address both the symptoms and underlying causes of dentinal hypersensitivity. Based on clinical findings, your dentist may recommend:
- Desensitizing toothpaste containing compounds such as potassium nitrate or stannous fluoride to occlude dentinal tubules and reduce neural transmission.
- Topical fluoride therapy to remineralize enamel and strengthen tooth structure.
- Dental sealants or bonding agents to cover exposed dentin and reduce sensitivity.
- Restorative treatment for carious lesions or structural defects.
- Periodontal therapy if gum recession or gingival inflammation is contributing to exposure.
Our approach goes beyond symptom relief—we focus on restoring long-term comfort and maintaining optimal oral health.
The Role of Professional Dental Cleanings
Routine professional prophylaxis (dental cleaning) is essential in preventing and managing sensitivity. Removal of plaque biofilm and calculus minimizes the risk of gingival recession, caries, and other contributing factors. Regular visits allow early detection and intervention, preserving both enamel integrity and periodontal health.
