There you are, enjoying your morning coffee, when a sudden jolt of pain comes from one of your teeth. As unpleasant, painful and disruptive to your morning routine as it is, a tooth sensitive to hot food or drink can be more than a minor inconvenience. A change in the way your teeth react to hot and cold often means there's a much more advanced problem happening in your mouth. And identifying the cause of this sudden pain can go a long way to treating the issue so you can go back to your morning meal.
Causes of Sensitivity
The pain or sensitivity you feel can be attributed to number of oral health issues. Consider these potential causes, all of which can help you (and your dentist) address the problem efficiently:
- Enamel erosion. Teeth are protected by enamel, which is their first defence against hot, cold, sticky and abrasive items. When this enamel wears down, it can cause tooth decay, which exposes sensitive nerves within the pulp of the teeth. Enamel can become weaker with age, an acidic or sugary diet and a history of acid reflux disease.
- Cavities. Fissures in your teeth can expose the same tender nerves, so cavities – both big and small – can be the culprit as well. In fact, sensitivity to hot and cold foods is often a warning sign that a cavity is forming and it's time to make an appointment to see your dentist. Similarly, fillings that repair cavities can become loose or fall out, causing hypersensitivity where the original cavity was cleared out.
