8 Potential Causes of Tooth Sensitivity

Brushing Too Hard

Over time, brushing too hard or using a hard-bristled toothbrush can wear down enamel and expose the underlying dentin. This can result in tooth sensitivity. Switching to a soft-bristled toothbrush and practicing gentle brushing techniques help ease the pain.

Gum Disease

Inflamed and sore gum tissue associated with gum disease can contribute to tooth sensitivity. The loss of supporting ligaments exposes the root surface, leading to sensitivity. Thin gum tissue due to genetics or periodontal disease can also lead to gum recession. When gums pull away from the teeth, the roots become exposed, causing sensitivity. Treating gum disease is essential to alleviate this issue.

Teeth Grinding

Bruxism, or teeth grinding, can wear down enamel and expose the sensitive dentin layer. Using a mouthguard at night can help protect the teeth and alleviate sensitivity caused by grinding or clenching.

Teeth Whitening Products

Some teeth whitening products can increase tooth sensitivity. If you have sensitive teeth, consult your dentist about the best teeth whitening options specifically designed for sensitive teeth. 

Fluoridated Dental Products

Using a fluoridated dental mouth rinse or fluoridated toothpaste can decrease sensitivity. Fluoride is a naturally occurring mineral that strengthens and protects the enamel in your teeth. However, continued exposure to high fluoride levels may cause skeletal and digestive disorders later in life.

Plaque Buildup

The presence of plaque on the root surfaces can contribute to tooth sensitivity. Maintaining good oral hygiene practices, including regular brushing and flossing, prevents plaque buildup.

Acidic Foods

Regularly consuming acidic foods, such as citrus fruits, tomatoes, pickles, and tea, can gradually erode tooth enamel, exposing the underlying dentin and causing sensitivity. Limiting the consumption of acidic foods and rinsing your mouth with water afterwards can help minimise sensitivity.

Recent Dental Procedures

Temporary tooth sensitivity can occur after dental procedures like fillings, teeth cleanings, or restorations. It usually resolves on its own within a few weeks. If sensitivity persists or worsens, consult your dentist for further evaluation.

Consider the following tips to alleviate tooth sensitivity:

• Use desensitising toothpaste specifically formulated for sensitive teeth. Apply a thin layer to exposed tooth roots before bed.
• Maintain good oral hygiene practices, including regular brushing and flossing with a soft-bristled toothbrush.
• Avoid highly acidic foods and beverages that can further erode tooth enamel.
• Consider using fluoridated dental products, such as mouth rinses, to strengthen enamel and decrease sensitivity.
• Wear a mouthguard if you grind or clench your teeth.
• Schedule routine dental visits for professional exams, cleanings, and fluoride treatments.

Teeth sensitivity can significantly impact daily life, but understanding its potential causes and implementing appropriate care and treatment can alleviate discomfort. Whether it’s adjusting brushing habits, managing gum health, or using specialised dental products, taking proactive steps in oral care can help address teeth sensitivity effectively. 

If sensitivity persists or worsens, consult your dentist for a comprehensive evaluation and personalised treatment plan. Maintaining good oral hygiene and seeking professional dental care is key to achieving a pain-free, healthy smile.
