Top Causes of Sensitive Teeth and How to Prevent Them

Tooth sensitivity is a common concern that affects many individuals, particularly when consuming hot, cold, sweet, or acidic foods and beverages. In North Surrey, increasing awareness about the causes of sensitive teeth can help residents take appropriate steps to prevent discomfort and preserve long-term oral health. At Opal Dental, we aim to provide clear, factual information to support proactive dental care.

What Causes Tooth Sensitivity?

Tooth sensitivity typically occurs when the protective enamel on teeth becomes worn or when gum recession exposes the dentin underneath. Dentin contains tiny tubules that lead to the nerve centre of the tooth. When exposed, these tubules allow external stimuli to reach the nerves, resulting in sharp or uncomfortable sensations.

There are several common causes of enamel wear and dentin exposure:

● Brushing too hard: Using excessive force or a hard-bristled toothbrush can wear down enamel and contribute to gum recession.

● Gum disease: Inflammation and infection of the gums can lead to tissue loss, exposing the roots of teeth.

● Tooth grinding (bruxism): Habitual grinding or clenching of teeth can damage enamel and cause sensitivity.

● Acidic foods and drinks: Citrus fruits, soda, and vinegar-based products can erode enamel over time.

● Tooth decay or worn fillings: Cavities or deteriorated restorations can expose inner tooth layers.

How to Prevent Tooth Sensitivity

Preventing tooth sensitivity involves protecting enamel, maintaining healthy gums, and addressing underlying conditions. Practical steps include:

● Use a soft-bristled toothbrush and gentle brushing technique: Brushing in circular motions with light pressure helps avoid enamel abrasion and gum recession.

● Choose toothpaste formulated for sensitive teeth: These products help block transmission of stimuli to tooth nerves and often contain ingredients like potassium nitrate or stannous fluoride.

● Limit intake of acidic foods and drinks: Reducing frequency and rinsing with water after consumption can help protect enamel.

● Wear a nightguard if grinding is a concern: Custom or over-the-counter nightguards can reduce enamel wear caused by bruxism.

● Regular dental checkups: Early detection of gum issues or enamel erosion allows for timely intervention.

● Practice good oral hygiene: Brushing twice a day and flossing once a day helps prevent plaque buildup and reduces the risk of gum disease.

Incorporating these practices into a structured dental care plan ensures a more effective approach to prevention.

Long-term Considerations for Oral Comfort

While common, tooth sensitivity can often be managed or prevented with consistent oral care. Addressing contributing factors early reduces the likelihood of persistent discomfort and helps maintain a stable oral environment. Preventative strategies not only protect enamel but also support overall dental function.
