Causes and Symptoms of Tooth Infections

What Are Tooth Infections?

Tooth infections occur when bacteria invade the inner parts of the tooth or the surrounding tissues. These infections can cause significant discomfort and, if left untreated, may lead to serious complications.

Causes of Tooth Infections

Several factors can contribute to tooth infections. Severe cavities, where bacteria break down sugars and create acid that attacks the tooth's enamel, are a common cause. Broken, chipped, or cracked teeth provide an entry point for bacteria to reach the pulp. Gum disease, which is an infection and inflammation of the tissues around the teeth, allows bacteria to access deeper areas. Even trauma to a tooth can make the inner pulp susceptible to infection. Additionally, poor oral hygiene, such as not brushing and flossing regularly, and frequently consuming sugary foods and drinks increase the risk. Certain medications or aging-related issues that cause a dry mouth also raise the chances of tooth decay and subsequent infection.

Symptoms of Tooth Infections

The symptoms of a tooth infection can vary. A severe, constant, throbbing toothache that spreads to the jawbone, neck, or ear is a common sign. Other symptoms include tooth sensitivity to hot or cold, a bitter taste in the mouth, bad breath, gum redness and swelling, a loosening tooth, a swollen area in the jaw, an open, draining sore on the gums, fever, and swollen lymph nodes. General discomfort and uneasiness may also be present.

When to See a Doctor

If you experience any of these symptoms, it's essential to seek medical attention promptly. A dentist can perform a thorough examination, which may include dental X-rays or a CT scan to assess the extent of the infection. They may also tap on the tooth or conduct pulp vitality tests to determine the health of the tooth pulp.

Treatment Options

Treatment aims to eliminate the infection and prevent complications. Options include incision and drainage of the abscess to remove the pus, root canal therapy to remove the infected pulp and fill the space, tooth extraction if the tooth is too damaged, and antibiotics to assist in the healing process. However, antibiotics alone won't solve the underlying problem, which is the infected tooth.

Prevention and Management

Preventing tooth infections involves maintaining good oral hygiene by brushing twice a day, flossing daily, and visiting the dentist for regular check-ups and cleanings. If you have a loose or chipped tooth, seeing a dentist promptly is crucial. While waiting for an appointment, warm saltwater rinses and over-the-counter pain relievers can offer temporary relief, but they do not cure the infection.

Outlook and Prognosis

With timely treatment, a tooth abscess should clear up. However, if left untreated, the infection can spread to surrounding tissues and cause more serious health problems. It's important to schedule an appointment with a dentist as soon as symptoms arise or visit the emergency room if there are severe complications like a high fever, difficulty swallowing, facial swelling, confusion, or an elevated heart rate.
