Tooth sensitivity, also known as hypersensitivity, is a condition characterized by discomfort and pain resulting from the erosion of enamel, which exposes the underlying dentin layer.

In a discussion with HT Lifestyle, Dr. Keshav Naithani, the senior director and head of the oral oncology department at Max Multi Speciality Centre in Noida, explained, “Tooth sensitivity, or dentin hypersensitivity, is a prevalent dental issue that occurs when the protective enamel diminishes, revealing the dentin beneath. This layer contains tiny tubules that connect to nerve endings, making teeth more vulnerable to pain triggered by hot, cold, sweet, or acidic substances. Sensitivity may also arise from gum recession, cavities, or enamel wear due to practices such as aggressive brushing or teeth grinding.”

Nevertheless, with appropriate choices and care, it is possible to prevent tooth sensitivity and associated discomfort.

Use desensitising toothpaste

Toothpaste specifically designed with ingredients like potassium nitrate or stannous fluoride can help obstruct pain signals from reaching the tooth's nerve, gradually alleviating sensitivity.

Opt for fluoride treatments

Professional fluoride applications can enhance enamel strength, encourage re-mineralization, and provide a protective barrier against external factors that may cause discomfort.

Consider dental sealants

These protective layers serve as a shield, covering exposed dentin and minimizing sensitivity by preventing external stimuli from affecting the nerves.

Use a mouthguard for bruxism

If you experience teeth grinding, a custom-made mouthguard can safeguard against enamel wear, which is a primary factor in tooth sensitivity.

Make lifestyle and dietary adjustments

Reducing the intake of acidic foods and drinks, such as citrus fruits and sodas, can help prevent additional enamel damage. Furthermore, using a soft-bristled toothbrush and employing gentle brushing methods can help protect your teeth.

Prioritise regular dental check-ups

Consistent dental visits enable professionals to assess your oral health, conduct thorough cleanings, and identify early indicators of issues that may lead to sensitivity.

Explore advanced dental treatments

In more serious situations, procedures like dental bonding, gum grafting, or root canal therapy might be suggested to resolve underlying problems and offer long-term relief.
