Tooth sensitivity occurs when the nerves of the tooth are irritated, resulting in pain or discomfort when exposed to hot or cold temperatures, while brushing, flossing, or chewing. This sensitivity arises when the protective layers of enamel and cementum are damaged, exposing the dentin layer of the tooth.
Causes of tooth sensitivity include:
- Tooth decay, trauma, or erosion damaging the enamel or cementum
- Poor oral hygiene leading to tooth decay
- Brushing too vigorously, causing wear and tear on the tooth
- Gum recession or inflammation
- Presence of bacteria, plaque buildup, or bad breath
- Teeth grinding or use of tooth whitening products
Symptoms of tooth sensitivity may include bad breath, pus or discharge from the tooth, receding gums, and redness and swelling of the gums.
To reduce tooth sensitivity, it’s essential to maintain good oral hygiene practices:
- Brush and floss regularly using proper techniques
- Use a soft-bristled toothbrush to avoid damaging the gum tissue
- Choose toothpaste designed for sensitive teeth
- Avoid teeth grinding and seek treatment if necessary
- Schedule regular dental check-ups to address any concerns and receive professional care.
