There are a range of causes of sensitive teeth. We can find:
- Exposed sensitive tooth – Short and sharp pain to cold may be due to receded gums and exposed sensitive tooth structure. We may need to place a filling over the exposed tooth to seal it from stimuli.
- Cracked tooth – Short and sharp pain to cold and also on biting, particularly grainy food may be due to a crack-line in a tooth. We may need to prevent pain and protect the tooth from crack growth with a crown.
- Decay and infection – Prolonged, severe pain may be due to tooth decay causing damage to a nerve space. We may need to do root canal therapy in these cases.
