Understanding tooth hypersensitivity
Tooth hypersensitivity manifests as a sharp, brief pain when a tooth is exposed to stimuli such as cold, heat, or physical contact. This uncomfortable sensation originates directly from the dentin, an inner layer located beneath the enamel, rich in nerve endings. When enamel or gums recede and expose the dentin, microscopic channels become vulnerable, causing the characteristic pains associated with this condition.
Main causes of tooth hypersensitivity
Several factors contribute to the onset of hypersensitivity. Abrasion caused by overly vigorous brushing or the use of a toothbrush with hard bristles is one of the most common causes. Acid erosion from a diet high in acidic foods (such as citrus fruits, sodas, and vinegar) or regular gastric reflux also weakens enamel, gradually exposing dentin. Gingival recession, often observed in individuals with periodontal diseases or inadequate oral hygiene, is another major factor in hypersensitivity. Finally, bruxism, the involuntary grinding of teeth at night, gradually wears down dental surfaces, increasing vulnerability to stimuli.
How to recognize tooth hypersensitivity: differential diagnosis
To accurately diagnose dental hypersensitivity, a dentist must rule out other dental conditions. Unlike pain caused by cavities or pulpitis (inflammation of the tooth nerve), hypersensitivity is brief and quickly subsides after the stimulus is removed. Persistent or nocturnal pain, however, more likely indicates pulpitis. A visual and radiological dental examination, sometimes accompanied by thermal tests performed in-office, confirms the diagnosis and helps rule out other pathologies.
Practical tips to reduce sensitivity in daily life
A few daily adjustments can significantly alleviate the discomfort associated with dental hypersensitivity. Gentle brushing with a soft toothbrush and toothpaste specifically designed to protect exposed dentin considerably limits symptoms. Regular application of dental varnishes in a clinical setting can also protect exposed areas and provide lasting relief.
Professional treatments at Clinique dentaire Métro Papineau
At Clinique dentaire Métro Papineau, several professional approaches are available for effectively treating hypersensitivity. Gentle scaling helps remove subgingival dental plaque while preserving dentin. Applying protective agents specifically designed for exposed dental collars reduces pain. The use of concentrated fluoride gels strengthens tooth mineralization, making teeth more resistant to external aggressions. Personalized nutritional counseling complements these treatments by directly addressing dietary factors responsible for enamel and gum deterioration.
Scheduling an appointment at the first signs of symptoms helps prevent deterioration of your oral health and ensures effective management of your hypersensitivity.
