Teeth sensitivity

Teeth Sensitivity

Teeth sensitivity, also known as dentin hypersensitivity, is a common dental problem that affects approximately 1 in 8 people. It is characterized by a sharp, sudden pain that is triggered by stimuli such as hot or cold temperatures, sweet or acidic foods and drinks, or even a rush of air.

Causes

Teeth sensitivity is typically caused by the exposure of dentin, the layer beneath the tooth's enamel. This can occur due to several reasons:

• Tooth decay: Cavities or tooth decay can erode the enamel and expose the dentin.
• Gum disease: Inflammation of the gums can cause them to recede, exposing the root surfaces of the teeth, which are not protected by enamel.
• Tooth grinding: Excessive grinding or clenching of the teeth can wear down the enamel.
• Acidic foods: Regular consumption of acidic foods and drinks can gradually erode the enamel.
• Tooth whitening products: Some tooth whitening products contain harsh chemicals that can wear down the enamel.

Symptoms

The primary symptom of teeth sensitivity is a sharp, sudden pain in response to certain stimuli. This can include:

• Hot or cold temperatures
• Sweet or acidic foods and drinks
• Brushing or flossing
• Exposure to air

Treatment

Treatment for teeth sensitivity typically involves addressing the underlying cause. This can include:

• Using a sensitive toothpaste: These toothpastes contain compounds that help to block the transmission of pain signals from the tooth surface to the nerve.
• Fluoride treatment: A dentist can apply a fluoride gel or varnish to the teeth to strengthen the enamel and reduce pain.
• Dental procedures: In severe cases, a dentist may recommend procedures such as a filling, a crown, an inlay or bonding to protect the exposed dentin.
• Root canal treatment: If the sensitivity is severe and persistent, a root canal treatment may be recommended to remove the tooth's pulp and replace it with a biocompatible material.

Prevention

Preventing teeth sensitivity involves maintaining good oral hygiene and avoiding behaviors that can wear down the enamel. This can include:

• Brushing and flossing regularly
• Using a soft-bristled toothbrush
• Avoiding acidic foods and drinks
• Not grinding or clenching the teeth
