Sensitive teeth is a common problem in Australia. Hypersensitivity or increased sensitivity is caused when the dentine is exposed. The dentine is the inner layer of a tooth that is normally covered by enamel. Consequently, hypersensitivity can be caused by a number of reasons:
– Abrasion lesions due to excessive tooth brushing: This causes the exposure of the roots. Since the roots are not covered by enamel, the dentine will be exposed, thus causing
sensitivity to hot and cold.
– Fractured tooth: Sometimes a tooth can be fractured due to excessive occlusal force, tooth wear or because of expansion of filling materials. This fracture line causes exposure of dentine and will result in hypersensitivity.
– Decayed tooth: When the enamel layer of the tooth is decayed, the dentine will be exposed, thus causing sensitive teeth.
It is best to consult your dentist when you start feeling hypersensitivity reactions. Treatments might range from using anti-sensitive toothpaste and oral hygiene instruction to covering the exposed dentine with dental restorative materials.
