Tooth sensitivity, or hyperesthesia, is a common dental problem encountered by patients of all ages. Sharp pain when consuming hot, cold, acidic, or sweet foods significantly reduces quality of life. The primary cause of this condition is damage or abrasion of the tooth's protective layer, which exposes the dentinal tubules.
Main causes of enamel thinning and hyperesthesia
Tooth enamel is the hardest tissue in the human body; however, it is susceptible to destruction under the influence of various factors. The main causes of the loss of enamel's protective properties and the development of increased sensitivity include:
- Mechanical damage due to aggressive tooth brushing or bruxism.
- Gingival recession (exposure of tooth roots), which compromises the integrity of periodontal tissues [6].
- Frequent consumption of acidic foods and beverages that cause enamel erosion.
- General systemic diseases and inflammatory processes in the oral cavity, including diabetes mellitus and immune disorders [3].
The relationship between pain, sensitivity, and general health
Pain perception in the maxillofacial region can depend on a multitude of accompanying factors. For example, clinical studies show that patients with neurological conditions, such as migraines, have altered pain sensitivity and react differently to odontogenic pain and thermal stimuli [1]. Furthermore, chronic inflammation and comorbidities, such as diabetes mellitus or thyroid disease, can exacerbate the condition of the mucous membrane and hard dental tissues, increasing discomfort [3, 8].
Modern treatment methods for tooth sensitivity
Effective therapy for hyperesthesia always begins with addressing the root cause. Modern dentistry offers a comprehensive approach to tooth protection:
- Use of remineralizing gels and varnishes that saturate the enamel with calcium, fluoride, and phosphate ions.
- Procedures for sealing and covering exposed dentinal tubules using specialized adhesive systems.
- Surgical treatment of gingival recession to cover exposed tooth roots using advanced techniques [6].
- Correction of oral hygiene and the selection of soft toothbrushes with toothpaste for sensitive teeth.
Prevention and care for sensitive teeth
To prevent enamel destruction and the onset of unpleasant sensations, it is important to follow simple preventive rules. Regular check-ups with a dentist allow for the timely detection of initial enamel wear or gum inflammation. For patients with hypertension or high anxiety in the dental chair, sedation methods may be used to reduce stress during treatment [5]. Caring for overall health and the timely treatment of chronic diseases also directly affect the state of the oral cavity.
