A Quick Guide to Tooth Infections

TOOTH INFECTIONS ARE more than just painful; they are serious conditions that require prompt attention. Left untreated, they can spread beyond the tooth and gums, leading to severe health complications. As endodontists, we specialize in treating infections inside the tooth and preserving natural teeth whenever possible. Here’s a quick guide to understanding tooth infections, their symptoms, and how they are treated.

What Is a Tooth Infection?

A tooth infection, also called a dental abscess, occurs when bacteria enter the pulp of the tooth. The pulp is the innermost layer that contains nerves, blood vessels, and connective tissue. When bacteria reach this area, usually through untreated cavities, cracks, or trauma, the pulp can become inflamed or infected. As the infection worsens, it may spread to the root tip and surrounding bone, causing significant pain and swelling.

Common Causes of Tooth Infections

Tooth infections often develop from problems that start small and gradually worsen. The most common causes include:

• Untreated tooth decay: Cavities that progress deep into the tooth can allow bacteria to reach the pulp.
• Cracks or chips: Even small fractures in the enamel create openings for bacteria.
• Failed dental work: Old fillings or crowns that break down over time may allow bacteria to leak into the tooth.
• Trauma: Injuries that damage the pulp, even without visible cracks, can lead to infection.

Symptoms to Watch For

The signs of a tooth infection can vary, but common symptoms include:

• Persistent or throbbing toothache
• Pain that radiates to the jaw, ear, or neck
• Sensitivity to hot or cold that lingers after the source is removed
• Swelling in the gums, face, or lymph nodes
• A bad taste in the mouth or foul-smelling breath
• A visible gum boil or pimple that may drain pus

If you notice these symptoms, it is important to seek dental care quickly. Infections do not resolve on their own and can become life-threatening if bacteria spread to the bloodstream.

How Endodontists Treat Tooth Infections

Endodontists specialize in saving teeth through root canal treatment. This procedure removes the infected pulp, thoroughly cleans the root canals, and seals the tooth to prevent further infection. In some cases, endodontic surgery may be recommended to address infections near the root tip.

Treatment is usually highly successful, allowing patients to keep their natural teeth and return to normal function. With modern techniques and anesthesia, root canal treatment is no more uncomfortable than getting a filling.

Preventing Tooth Infections

While endodontists are experts at treating tooth infections, prevention is always best. You can reduce your risk by:

• Brushing and flossing daily
• Visiting your dentist for routine checkups and cleanings
• Treating cavities promptly
• Wearing a mouthguard during sports to prevent dental injuries
• Avoiding habits like chewing ice or hard objects that can crack teeth

Protecting Your Smile

Tooth infections can be frightening, but with early recognition and expert care, they are very treatable. Endodontists are dedicated to saving natural teeth and relieving pain, offering advanced care when infections occur. If you experience symptoms of a tooth infection, do not wait — prompt treatment is the key to protecting your smile and your overall health.
