Yes, an infected tooth can absolutely cause a fever. This is because an infection in your tooth, known as an abscess, doesn't stay localized. Bacteria from the infection can spread throughout your body via your bloodstream, triggering your immune system's response and leading to a fever. The severity of the fever can vary depending on the extent of the infection and your overall health. Let's delve deeper into this important topic.
What is a Tooth Abscess?
A tooth abscess is a pocket of pus that forms at the root of a tooth or between the tooth and the gum. This pus is a collection of white blood cells, dead tissue, and bacteria fighting the infection. The bacteria responsible are often those already present in your mouth, but a cavity, gum disease (periodontal disease), or a cracked tooth can provide an entry point for them to reach the tooth's pulp (the inner, soft part of the tooth).
How Does a Tooth Infection Cause a Fever?
When bacteria invade the tooth's pulp, the body's immune system recognizes this as a threat. The immune system responds by sending white blood cells to fight the infection. This process releases chemicals called pyrogens, which travel to the hypothalamus in your brain. The hypothalamus is responsible for regulating your body temperature. Pyrogens cause the hypothalamus to raise your body temperature, resulting in a fever.
What are the Symptoms of a Tooth Abscess Besides Fever?
A fever isn't the only symptom of a tooth abscess. You might also experience:
- Severe, throbbing toothache: This is often the most noticeable symptom.
- Sensitivity to hot and cold: Your tooth may be exquisitely sensitive to temperature changes.
- Swelling in your gums or face: The area around the infected tooth may become swollen and tender.
- Bad breath: A persistent foul odor in your breath can indicate an infection.
- Pain when biting or chewing: This can make eating difficult or even painful.
- Tender lymph nodes: You may feel swollen lymph nodes in your neck or jaw.
- Pus: You may notice pus draining from the infected area.
How High Can a Fever Get from a Tooth Infection?
The fever associated with a tooth infection can range from mild (low-grade) to high. A low-grade fever might be around 100-101°F (37.8-38.3°C), while a higher fever could reach 103°F (39.4°C) or more. A high fever warrants immediate medical attention.
What Should You Do if You Have a Fever and Tooth Pain?
If you're experiencing both a fever and tooth pain, it's crucial to seek professional dental care immediately. Delaying treatment can lead to more serious complications, such as:
- Spread of infection: The infection can spread to other parts of your face, head, or even your bloodstream (leading to sepsis, a life-threatening condition).
- Bone loss: Prolonged infection can damage the bone supporting your teeth.
- Cellulitis: A severe bacterial infection that affects the skin and soft tissues.
Can Antibiotics Cure a Tooth Infection and Fever?
Antibiotics are often prescribed to treat tooth infections and bring down the fever. However, antibiotics alone won't cure the underlying infection; they only fight the bacteria. You'll likely need a root canal or extraction to fully resolve the infection. Your dentist will determine the best course of action based on your individual situation.
When Should I See a Dentist Immediately?
Don't hesitate to contact your dentist immediately if you experience:
- Severe tooth pain
- High fever
- Facial swelling
- Difficulty swallowing or breathing
Addressing a tooth infection promptly is essential to prevent serious complications. Early intervention is key to resolving the problem and preventing further health issues.
