What Causes a Tooth Infection and How Can It Be Treated?

Did you know that over 90% of adults have experienced tooth decay, a leading cause of tooth infection, at some point in their lives? While cavities may seem minor, untreated dental issues can quickly escalate into painful infections that affect not just your mouth but your overall health. A tooth infection is more than just a sore tooth; it’s a signal from your body that bacteria have taken hold inside your tooth or gums and need to be treated promptly.

Caused by decay, fractures, or gum disease, a tooth infection can lead to symptoms such as sharp pain, swelling, or even systemic illness if untreated. Dentists use physical exams and X-rays to confirm the issue, then tailor treatment using root canals, antibiotics, or extractions. Prevention lies in brushing, flossing, routine check-ups, and addressing problems early, helping you avoid discomfort and protect your smile long-term.

So, what causes a tooth infection and how can it be treated? Let’s explore the causes, symptoms, and effective treatment options so you can act quickly if you ever experience this dental dilemma.

What Exactly Is a Tooth Infection?

A tooth infection, also known as a dental abscess, occurs when bacteria enter the tooth or its surrounding structures. This usually happens when a cavity, crack, or gum issue allows bacteria to reach the pulp; the soft tissue inside your tooth containing nerves and blood vessels. Once inside, the bacteria multiply and create pus, leading to swelling, pain, and in some cases, serious complications if left untreated.

Common Causes of a Tooth Infection

1. Untreated Cavities

Tooth decay is the most common cause. When plaque builds up and erodes the enamel, cavities form. If left unchecked, bacteria can burrow deeper into the tooth and reach the inner pulp, causing an infection.

2. Cracked or Damaged Teeth

Whether from trauma, grinding, or biting down on something hard, a cracked tooth can allow bacteria to slip into the pulp chamber unnoticed.

3. Gum Disease (Periodontitis)

Advanced gum disease affects the tissues and bones supporting the teeth. As gums recede and pockets form, bacteria find easy access to tooth roots and nerves.

4. Poor Dental Hygiene

Inconsistent brushing, flossing, and skipping dental check-ups provide the perfect environment for bacteria to thrive.

5. Previous Dental Procedures

In some cases, a failed root canal or poorly done filling can become a breeding ground for bacteria, especially if the seal wasn’t tight.

Recognising the Signs of a Tooth Infection

While some infections develop slowly, others escalate quickly. Be alert to these common symptoms:

• Persistent, throbbing toothache

• Sensitivity to hot or cold

• Swelling in the face or cheek

• Bad taste or foul odour in the mouth

• Red or swollen gums

• Fever

• Swollen lymph nodes

If you’re experiencing any of the above, it’s essential to consult a professional at your trusted Rouse Hill Smiles Dental Clinic before the infection spreads further.

How a Tooth Infection Is Diagnosed

Dentists typically perform a physical examination and ask about your symptoms. In many cases, an X-ray will be used to detect the location and severity of the infection. This helps the dentist determine whether the infection is localised or if it has spread to other areas of the jaw or face.

Effective Treatment Options

1. Drainage and Cleaning

For minor abscesses, the first step is often to drain the pus and clean the infected area. This provides immediate relief from pressure and pain.

2. Root Canal Therapy

A common and highly effective treatment. During a root canal, the infected pulp is removed, and the inside of the tooth is cleaned, disinfected, and sealed to prevent further infection.

3. Tooth Extraction

If the tooth is severely damaged and cannot be saved, it may need to be removed. Your dentist will discuss replacement options like implants or bridges.

4. Antibiotics

In cases where the infection has spread or is severe, antibiotics may be prescribed. These won’t fix the underlying cause but help reduce the infection and support recovery.

5. Follow-Up and Restoration

After treatment, your dentist may recommend a crown or filling to restore the function and appearance of the affected tooth.

Preventing Future Tooth Infections

An ounce of prevention is always better than a root canal. Here’s how to keep your mouth infection-free:

• Brush twice a day with fluoride toothpaste

• Floss daily to remove food and plaque between teeth

• Avoid sugary snacks and drinks

• Attend regular dental check-ups at a trusted Rouse Hill Smiles Dental Clinic

• Wear a mouthguard if you grind your teeth or play contact sports

When to Seek Urgent Help

A tooth infection is not something to ignore. If you notice facial swelling, difficulty breathing or swallowing, or an intense fever, seek immediate medical or dental attention. These are signs that the infection may have spread to other parts of the body, which can be life-threatening.

Tooth infections usually begin with bacteria entering the pulp through decay, cracks, or gum issues, and symptoms like throbbing pain, swelling, or fever can indicate it’s time to act. Diagnosis often involves an X-ray and visual examination, while treatment may range from draining the abscess to performing a root canal or, in severe cases, removing the tooth entirely. Thankfully, these issues are preventable through consistent dental care and hygiene, making early action and professional guidance crucial.
