Top 5 Common Tooth Infection Symptoms and How to Treat Them
A tooth infection—often called a dental abscess—occurs when bacteria penetrate deep into a tooth’s pulp or surrounding tissues, triggering pain, swelling, and other distressing symptoms. If left untreated, the infection may spread to surrounding bone, soft tissues, or even other parts of the body. Recognizing warning signs early and seeking prompt dental care are crucial steps toward relief and recovery.
Here are the top 5 common symptoms of a tooth infection, along with the recommended treatments:
1. Persistent, Throbbing Tooth Pain
Symptom:
One of the earliest and most consistent red flags is a continuous, severe toothache. The pain may be sharp, throbbing, or radiate outward to the jaw, ear, or neck. It may worsen when you lie down or when pressure is applied, such as when biting or chewing.
Why it occurs:
The infection leads to inflammation within the inner pulp of the tooth, increasing pressure and stressing nerve endings.
Treatment:
Pain relief alone is not enough. A dentist will need to eliminate the infection source. In many cases:
- Root canal therapy is performed to remove infected pulp, clean and seal the canals.
- If the tooth is too damaged to save, extraction may be necessary.
- Meanwhile, over-the-counter analgesics (ibuprofen or acetaminophen) can temporarily ease pain.
2. Sensitivity to Hot, Cold, or Pressure
Symptom:
An infected tooth often becomes overly sensitive to temperature changes—hot drinks, cold ice cream, or air exposure may provoke sharp discomfort. Similarly, pressure from chewing or tapping can intensify pain.
Why it occurs:
The inflamed pulp becomes more reactive to external stimuli, as nerves become hypersensitive.
Treatment:
- The long-term fix is the same: removal of infected tissue (via a root canal or extraction).
- In the short term, avoid extremely hot or cold foods and drinks. Use lukewarm rinses.
- A soft diet and gentle brushing help prevent aggravation until professional care is possible.
3. Swelling, Gum Bumps or Facial Puffiness
Symptom:
You may notice swelling near the affected tooth’s gum line, possibly forming a pimple-like bump (gum boil). In more severe cases, facial or cheek swelling may develop. The gums may also feel firm or tender.
Why it occurs:
The body tries to contain the infection by forming pus, which exerts pressure on surrounding tissues, causing visible swelling.
Treatment:
- Dentists often perform incision and drainage to allow pus to escape, reducing pressure.
- After drainage, the area is cleaned, disinfected, and in many cases a root canal follows.
- If drainage alone is not sufficient and the tooth is non-salvageable, extraction may be required.
- In severe cases or when the infection has spread, systemic antibiotics are prescribed to help control bacterial spread.
4. Fever, Swollen Lymph Nodes & General Malaise
Symptom:
When a dental infection begins to affect broader areas of the body, you may experience systemic symptoms: fever, chills, fatigue, swollen lymph nodes under the jaw or in the neck, and a general feeling of being unwell.
Why it occurs:
This indicates that bacteria or their toxins may be entering the bloodstream or lymphatic system. It’s a warning that the infection is no longer localized.
Treatment:
- Urgent dental attention is essential to prevent further spread.
- Antibiotics become more critical in these cases to support the body’s defense.
- Drainage or surgical intervention may be needed if abscesses have migrated or formed deeper pockets.
5. Bad Taste, Bad Breath, and Gum Drainage
Symptom:
A foul or metallic taste in the mouth, persistent bad breath (halitosis), or an unexpected release of fluid or pus (perhaps salty or foul-smelling) into your mouth are strong indicators of infection.
Why it occurs:
Pus forming in the abscess may leak into the oral cavity or escape through gum tissues, creating an unpleasant taste and odor.
Treatment:
- Professional drainage is essential to remove the pus and relieve symptoms.
- Thorough cleaning of the root canal or extraction will eliminate the infected source.
- Antibiotics may accompany treatment if bacterial spread is suspected.
- In the meantime, gentle saltwater rinses may help mitigate odor and reduce bacterial load (but should not replace dental care).
When to Act — Don’t Delay Treatment
If any of these symptoms appear—particularly when pain worsens, swelling increases, or fever develops—do not delay seeing a dentist. A tooth infection can escalate into serious complications, including bone infection, spread into adjacent tissues such as sinuses or neck, and in extreme cases, systemic infection.

Preventing Tooth Infections: Tips That Help
- Maintain good oral hygiene: brush twice daily with fluoride toothpaste, floss once daily, and use an antibacterial mouth rinse.
- Attend regular dental checkups and cleanings to catch cavities before they worsen.
- Limit sugary foods and drinks, which contribute to decay.
- If you notice early signs like tooth sensitivity or minor pain, visit your dentist rather than waiting.
By knowing these symptoms and acting promptly, you can avoid escalating pain, risk to your general health, and costly treatments later. Let your smile stay healthy, strong, and infection-free.
