Having sensitive teeth can mean anything from a slight twinge to a serious pain lasting many hours. You are more likely to feel the sensitivity when drinking or eating something cold, from cold air catching your teeth, and sometimes with hot foods or drinks. Some people have sensitivity when they have sweet or acidic food and drinks.
Tooth is made up of an outer layer called enamel and an inner layer called dentine. The hard outer enamel protects the dentine which is softer and more sensitive to external stimuli such as hot and cold, and is more prone to wear.
The following dental issues can cause sensitive teeth:
The cause of sensitive teeth needs to be determined first. Treatment could be as simple as using a desensitising toothpaste (such as Sensodyne), or it may involve protection of an exposed dentine or nerve ending using fillings or crowns. However if your pain is caused by gum loss exposing the root surfaces, we may recommend a gum grafting to protect the root surface and help your tooth.
If the underlying problem isn’t clearly identified and addressed, it is highly likely sensitivity will progressively get worse. Additionally, depending on the source of your sensitivity, irreversible tooth damage may be caused resulting in eventual tooth loss.
