16 Common Causes of Toothache (Toothache) – Forbes Health

To understand what a toothache is, you have to start with a tooth’s anatomy, says Bill Dorfman, DDS, a dentist in Los Angeles. “Teeth are mostly composed of non-vital hard organic material, and this part of the tooth has no nerves or sensations,” he says. The center of the tooth has a blood supply and nerve, which mainly function to keep the tooth from drying out and drying out. Once a tooth dries out, it becomes brittle and more prone to fractures. A typical toothache is when this nerve in the tooth becomes inflamed or dies. Once the nerve dies, it produces toxins around the tooth that become an infection.

There are two classifications of dental inflammation (which is the source of the pain): reversible and irreversible.

“It is often difficult to determine whether a tooth needs root canal treatment [the treatment for irreversible tooth inflammation] or not,’ says Dorfman. “We can do many tests, but one of the simple ones is to see how teeth react to hot or cold. If a tooth doesn’t respond to temperature, it’s usually dead, but not always.”

When a toothache is reversible, it means that when heat, cold, or pressure is applied to the tooth, the pain will lessen and disappear as the tooth heals. Also, if the tooth only reacts while the stimulus is on the tooth, it is probably inflamed, but can still heal.

However, in the case of an irreversible toothache, the pain does not stop after the stimulus is applied. If this is the case, you probably need a root canal, says Dorfman. “When a tooth needs a root canal, it’s because the tooth’s nerve has died or is dying,” he says.

Once the nerve dies it becomes necrotic and if left in it the tooth can cause a massive infection. “When you do a root canal, you remove the nerve and fill the tooth with an inert material, so hopefully you can keep the tooth for many years,” he says.

Common toothache symptoms include the following, says Sharon Huang, DDS, founder of Les Belles NYC Dentistry in New York:
