Don’t Believe the Disappearing Act; Here’s What to Do if Your Toothache Suddenly Vanishes

The outer layer of teeth is made from enamel, which is the strongest material naturally occurring in the human body. While enamel is incredibly tough, it is not invincible and lacks the ability to heal itself, and infections that breach the outer layers of a tooth are usually incredibly painful. Here’s a quick look at how toothaches happen, why they may seem to suddenly disappear, and why it’s important to seek professional dental care if this happens.

How Do Toothaches Happen?

The human mouth is home to many types of bacteria, and some of them will cause destructive oral infections if they are allowed to multiply too much (usually due to poor oral habits). The first stage of a tooth infection is a pre-cavity spot that can usually be reversed with improved hygiene habits. However, an untreated infection will eventually become a cavity that will only get worse without professional help. If left unaddressed, the cavity will penetrate to the pulp at the center of the tooth, causing a severely painful infection that may lead to tooth loss and a host of other unpleasant oral and overall health consequences.

What If My Toothache Suddenly Disappears?

While a nasty, persistent toothache suddenly disappearing may seem like a relief, this usually means the problem has gone from bad to worse. A vanishing toothache may indicate that the bacteria inside the tooth have killed the nerve ending in the pulp, which will prevent pain signals from being sent to the brain. Even if no pain is present, the infection will only get worse until the tooth is destroyed. In some cases, this can also lead to dangerous secondary infections like sepsis.

How Can My Emergency Dentist Help?

Luckily, your local dentist is trained and equipped to effectively address an agonizing toothache by eliminating the infection at its source and rebuilding lost dental structure. In many cases, this means performing a root canal, which involves removing the infected pulp, sanitizing and filling the inner chamber of the tooth, and placing a beautiful dental crown to restore the tooth’s function and appearance. The root canal process is painless, and while the patient may experience some mild and temporary discomfort while recovering, it will certainly be far preferable to the ongoing misery of an untreated toothache.

Don’t let a disappearing toothache lull you into a false sense of security. Seeking emergency dental care when you need it can help you keep your smile gorgeous and healthy for life.
