Tooth Sensitivity and Its Causes

12 September 2024

Tooth hypersensitivity, or increased sensitivity, is a common issue today, affecting around 40% of patients. This condition occurs when the enamel (the protective coating on teeth) weakens. The tooth's crown and roots contain tiny tubes leading to the tooth's nerve center. When the enamel wears down, these nerves are exposed, making the tooth sensitive to irritants like hot or cold foods, sugary items, or drinks. Irritants travel through the tubes to the nerve center, causing pain.

Common Causes of Tooth Sensitivity:

• Aggressive brushing: Brushing too hard or using a rough toothbrush can wear down enamel over time, increasing sensitivity.
• Gum disease (Periodontitis): Gum inflammation and recession expose tooth roots, leading to heightened sensitivity.
• Cracked teeth: Bacteria can enter cracks and reach the nerve center, increasing sensitivity.
• Tooth whitening products: Many whitening toothpastes and wipes contain abrasive substances like baking soda or peroxide, which can cause sensitivity.
• Age: Tooth sensitivity often peaks between the ages of 25 and 30.
• Dental plaque: Plaque buildup on the teeth can damage enamel, leading to sensitivity.

How to Prevent Tooth Sensitivity:

• Practice brushing and flossing techniques, and use an irrigator for hard-to-reach areas.
• Opt for a soft-bristled toothbrush to avoid enamel damage and gum irritation.
• Maintain a balanced diet, limiting acidic foods and drinks.
