Have you ever felt a sharp sensation in your teeth while drinking hot or cold water or eating certain food? If yes, you have sensitive teeth. This sharp sensation in the teeth is a condition known as “dental hypersensitivity” in medical term.
Here, Dr Sonam Shah who is a dentist currently working at Sunrise Oral & Dental Home explains about its causes and remedies:
Causes of tooth sensitivity
There is not a single cause for tooth sensitivity; several factors contribute to it:
- Enamel erosion: The outer layer of the tooth, called enamel, protects the inner layers. When enamel wears down, the underlying dentin becomes exposed, leading to sensitivity.
- Receding gums: If the gums recede from their natural position, the exposed tooth roots can cause discomfort.
- Cavities and decay: Tooth decay or previously treated teeth where the filling has worn out can lead to sensitivity.
- Dental procedures: Sometimes, sensitivity occurs after procedures like tooth fillings, bleaching, or cement application, though this usually subsides on its own.
- Use of acidic mouthwash: Mouthwashes with high acidity can weaken enamel and contribute to sensitivity.
How to reduce tooth sensitivity
1. Brush gently
Brushing too hard can weaken gums and aggravate sensitivity. Use a soft-bristled toothbrush and apply light pressure.
2. Use fluoride toothpaste
Fluoride strengthens tooth enamel and helps reduce sensitivity. Choose a toothpaste specifically designed for sensitive teeth.
3. Maintain oral hygiene
Brush twice daily and rinse your mouth with clean water after eating. Regular rinsing helps prevent bacterial growth and minimises sensitivity.
4. Saltwater rinse
Rinsing with warm salt water helps kill bacteria and soothe sensitive teeth. Try rinsing twice a day for relief.
5. Consult a dentist
If sensitivity persists for more than a week, consult a dentist. It could indicate an underlying issue that requires professional treatment.
Proper oral care and preventive measures can significantly reduce tooth sensitivity, ensuring stronger and healthier teeth.
