Tooth Pain Causes
Unfortunately, there are numerous ways that you can wind up with a toothache. Worn down tooth enamel or a recessed gumline can expose the tooth's dentin, the layer of hard tissue located under the enamel. This makes your teeth sensitive to cold and hot liquids or sugary drinks.
Cavities are another common pain trigger. Once the sensitive nerves in your teeth are exposed, an act as simple as biting something hard could be painful.
If you bite down on something too hard, you could have a cracked tooth. Trauma from an accident can also crack a tooth. A severe enough crack may expose the tender nerves that reside deep in your teeth.
Sometimes dental work that was performed to fix one problem can cause another problem. Fillings and crowns can become loose or cracked, resulting in tooth pain.
Your first inclination to relieve a toothache might be a cold compress or an over-the-counter pain medication. But there are other methods you can try.
