Tooth sensitivity is tooth discomfort in one or more tooth that is triggered by hot, cold or sour foods and drinks for even breathing cold air. The pain can be sharp, sudden and shoot deep into nerve endings of teeth.
Tooth sensitivity can be caused by following factors listed below:
- Tooth sensitivity occurs where underlying layers of teeth the dentine becomes exposed. The roots which are not covered by hard enamal contain thousands of tinny tubules or channels leading to centre of tooth e.i. pulp. The channels allow stimuli; hot, cold, sweet food to irritate the nerve, thus, resulting in the pain.
- The bacteria from the plaque may be trapped in the broken tooth and even enter the pulp, causing infection and inflammation.
- Clenching the teeth may wear down the enamel and expose the underlying dentine.
- Ageing process.
- Receding gums caused by gum disease of faulty techniques of brushing.
- Tooth decay.
- Plaque: The presence of plaque can cause tooth sensitivity.
- Acidic foods: Regular consumption of high acidic content such as citrus fruits, tomatoes and pickles can result in erosion of enamel.
- Abrasions: The wearing away of surface of tooth due to faulty techniques of mastication.
