In a healthy mouth, a coat of enamel protects the tooth crown. Under the gum line, there exists a layer called cementum to protect the tooth root. Beneath the enamel and the cementum lies what we call dentin. Dentin is a tissue that makes up the bulk of all teeth, essentially containing microscopic canals. And when dentin loses this protective layer of enamel or cementum, these canals allow heat and/or cold to reach the nerve cells inside the tooth and result in hypersensitivity or sensitive teeth.
Some of the reasons for tooth sensitivity are –
- Brushing your teeth too vigorously with a hard bristled brush, leading to loss of protective enamel layers
- Grinding your teeth while asleep or clenching your teeth during daytime
- Receding gums/gum disease
- Decay in the tooth surface exposing the underlying dentine surface
Our dentists at FDOC are specialized in diagnosing the root cause of sensitivity and treating them accordingly.
