Hyperesthesia – increased sensitivity of the dental tissues to the action of mechanical, chemical and thermal stimuli. Most often this phenomenon is observed in the pathology of tooth tissue of non-carious origin, as well as decay and periodontal disease.
Reasons of Hyperesthesia
Healthy teeth do not hurt and are not sensitive to external stimuli. To feel they begin only when damaged. Tooth decay, thinning enamel, cracks, exposure of tooth roots – the reasons why we feel the pain in the teeth. Dentin, enamel becomes thinner, and teeth nerves lose their protection, that is why the tooth becomes sensitive. Disorders are not always visible to the eye, but we it feel.
Manifestations of hypersensitivity the teeth
The main and the only manifestation that we feel – pain. Pain occurs as a reaction to:
- air flow;
- during chewing.
The pain may be barely noticeable, such we prefer to ignore. And there may be a sharp, severe pain. The sensitive areas may be on one tooth, but may be on the whole group of teeth.
63-65% of cases – systemic hypersensitivity. The reason of systemic tooth sensitivity are common: severe disease, nerve disorders. Sensitivity increases for all the teeth or the majority of them. Non-system sensitivity occurs in 35-37% of patients. The reasons for its occurrence – local factors. Suffers a particular tooth. Reasons for sensitive teeth:
- Dentine damage when dressing dental crown;
- General disturbances in the body;
- The destruction of tooth enamel;
- Erasing tooth enamel;
- Bare areas of the tooth root.
Hyperesthesia of teeth: Prevention
What to do in case of hypersensitivity teeth at home? Prevention hypersensitivity simple:
- complete oral hygiene, which includes systematic toothbrushing with prophylactic tooth-pastes that do not contain abrasive particles, and do not destroy the enamel;
- correct technique of cleansing teeth with a toothbrush average and minimum stiffness without risk to injure teeth and gums;
- careful use of whitening toothpaste with abrasive particles and chemical elements, that cause damage of the tooth enamel and the leaching of calcium from it;
- a balanced diet with plenty of foods rich in calcium and phosphorus;
- restriction of consumption of acidic fruits, berries and juices that destroy the enamel;
- systematic visits to the dentist twice a year.
