A tooth infection may start small, but if ignored, it can spread far beyond your mouth. When bacteria travel from an abscessed tooth into your bloodstream, jaw, or other organs, it can trigger severe health problems—even becoming life-threatening. Recognizing the symptoms of tooth infection spreading to the body early can make the difference between a quick recovery and dangerous complications.
In this guide, we’ll explain early warning signs, key symptoms, and what happens if a tooth infection goes untreated. You’ll also find prevention tips, home remedies for temporary relief, and when to see a dentist urgently.

What Happens When a Tooth Infection Spreads?
Normally, a dental infection is limited to the tooth or surrounding gum tissue. But when bacteria escape into your bloodstream or lymph nodes, it can reach vital organs like the heart, lungs, or brain. This condition is known as sepsis when it becomes systemic.
If left untreated, spreading infections may cause:
- Bone loss around the jaw
- Sinus infections
- Heart infections (endocarditis)
- Lung infections (pneumonia)
- Brain abscesses
- Life-threatening sepsis
“Ignoring an infected tooth is never safe. Once infection spreads beyond the tooth, the risks increase dramatically.”
Early Symptoms of Tooth Infection Spreading
Before the infection becomes severe, your body often gives subtle warning signs. These may include:
- Severe toothache that radiates to jaw, ear, or neck
- Persistent bad taste or foul breath
- Swelling of gums and jawline
- Tender lymph nodes under the jaw or in the neck
- Redness and heat around the infected tooth
These early signs indicate the infection is not staying localized.
Key Symptoms of Tooth Infection Spreading to Body
When the infection moves beyond your mouth, symptoms may become systemic and more alarming. Here are the main ones:
1. Fever and Chills
Your immune system raises body temperature to fight infection. A fever above 101°F (38.3°C) with chills may mean bacteria are spreading.
2. Swelling in Face or Neck
Swelling that extends to cheeks, under the eye, or down the neck is a red flag. This can even block airways in severe cases.
3. Fatigue and Weakness
When bacteria spread, your body works overtime to fight them, leaving you drained and exhausted.
4. Difficulty Breathing or Swallowing
This is one of the most dangerous symptoms. It can signal that swelling is pressing against your throat, blocking airflow.
5. Rapid Heartbeat
Your heart works harder during infection. A fast pulse, especially with dizziness, could point to sepsis.
6. Headache and Dizziness
If infection spreads toward the brain, symptoms like headache, confusion, or dizziness may appear.
7. Stomach Issues
Nausea, vomiting, or diarrhea may occur if infection toxins reach your digestive system.
8. Persistent Throbbing Pain
The pain may spread beyond the tooth to jaw, temple, or ear, showing deeper infection.
9. Night Sweats
Your body may alternate between fever and chills, leading to sweaty, restless nights.
10. General Feeling of Being Unwell
If you feel “off” with multiple symptoms combined, it could be a spreading infection.
Table: Localized Tooth Infection vs Spreading Infection
| Category | Localized Tooth Infection | Spreading Tooth Infection |
|---|---|---|
| Pain | Toothache only | Spreads to jaw, ear, neck |
| Swelling | Limited to gums | Extends to face/neck |
| Fever | Rare | Common (over 101°F) |
| Breathing/Swallowing | Normal | Difficult, restricted |
| Lymph Nodes | Not noticeable | Swollen and tender |
| Fatigue | Mild | Severe, body-wide exhaustion |
| Risk Level | Manageable with treatment | High, life-threatening |
When to See a Dentist Immediately
Seek urgent dental or medical care if you notice:
- Fever with swelling in face/neck
- Trouble breathing or swallowing
- Rapid heartbeat with dizziness
- Severe headache or confusion
- Pus draining from gums
“Any spreading tooth infection is a medical emergency. Delaying treatment could lead to sepsis and organ damage.”
Possible Complications of Untreated Infection
If symptoms are ignored, risks may include:
- Osteomyelitis (jaw bone infection)
- Ludwig’s angina (life-threatening throat swelling)
- Endocarditis (infection of heart lining)
- Brain abscess
- Sepsis (body-wide blood infection)
Each of these can be fatal without medical care.
Emergency Treatment Options
Doctors and dentists may use:
- Antibiotics (penicillin, clindamycin, amoxicillin)
- Root canal treatment to remove infection source
- Tooth extraction if damage is too severe
- Incision and drainage of abscess
- Hospital admission & IV antibiotics in serious cases
Temporary Home Remedies (Not a Cure)
While you wait for an appointment:
- Saltwater rinses
- Cold compress for swelling
- Over-the-counter painkillers (ibuprofen, acetaminophen)
- Clove oil for mild relief
“Home remedies may ease pain but will never cure the infection. Only a dentist can remove the root cause.”
Prevention: How to Avoid Tooth Infections
- Brush twice daily with fluoride toothpaste
- Floss once daily to remove trapped food
- Visit dentist every 6 months
- Avoid excess sugar and acidic foods
- Treat cavities early before they worsen
FAQs
Can a tooth infection spread to your body?
Yes, a tooth infection can spread to the body if left untreated. Bacteria from the infected tooth may travel through the bloodstream, leading to serious conditions like sepsis, heart infections, or even brain abscesses.
How do I know if my tooth infection is spreading?
Signs that a tooth infection is spreading include fever, swelling in the face or neck, fatigue, difficulty breathing or swallowing, and swollen lymph nodes. If you notice these symptoms, seek emergency dental care immediately.
How long does it take for a tooth infection to spread?
A tooth infection can spread within days to weeks if untreated. The exact time varies depending on your immune system and severity of infection. That’s why urgent dental treatment is strongly recommended.
Can a tooth infection make you sick to your stomach?
Yes. When bacteria or toxins from a dental infection enter the bloodstream, they can cause nausea, vomiting, and stomach upset. This is often a sign that the infection is spreading beyond the tooth.
What happens if a tooth infection goes untreated?
If untreated, a tooth infection can spread to the jaw, face, throat, and bloodstream. This may lead to life-threatening complications such as Ludwig’s angina, sepsis, or organ failure. Prompt dental care prevents these risks.
Key Takeaway
A tooth infection spreading to the body is not something to take lightly. If you have fever, swelling, or trouble breathing with a dental abscess, seek urgent care. Acting quickly may save your life.
