Tooth Infection Symptoms: Warning Signs You Shouldn’t Ignore
San Juan Capistrano, CA
A tooth infection—often caused by untreated decay, cracks, or gum disease—can quickly become serious if left untreated. Many people search for tooth infection symptoms because they’re experiencing pain, swelling, or pressure and aren’t sure whether it’s an emergency.
Here’s how to recognize the warning signs of a tooth infection and when it’s important to see a dentist right away.
What Is a Tooth Infection?
A tooth infection occurs when bacteria reach the inner pulp of the tooth or surrounding tissues. This often leads to inflammation, pus buildup (abscess), and pressure that causes pain.
Common causes include:
Untreated cavities
Cracked or broken teeth
Failed fillings or crowns
Advanced gum disease

Most Common Tooth Infection Symptoms
Tooth infections don’t always start with severe pain. In fact, early symptoms are often subtle.
Common warning signs include:
Persistent toothache or throbbing pain
Sensitivity to hot or cold
Swelling in the gums, face, or jaw
Bad taste or foul breath
Pressure or pain when chewing
Advanced Tooth Infection Symptoms (Medical Emergency)
If an infection spreads, symptoms may worsen and require immediate care.
Seek urgent dental or medical attention if you notice:
Facial swelling that spreads
Fever
Difficulty swallowing or breathing
Swollen lymph nodes in the neck
Pus draining from the gums
These symptoms may indicate an abscess or spreading infection.
Tooth Infection Symptoms at a Glance
Can a Tooth Infection Go Away on Its Own?
No. A tooth infection will not heal without treatment. Pain may temporarily subside, but the infection remains and can spread to surrounding tissues or bloodstream.
Antibiotics alone do not fix the source of the infection—they only control symptoms temporarily.
How Are Tooth Infections Treated?
Treatment depends on severity and may include:
Root canal therapy to remove infected tissue
Drainage of an abscess
Tooth extraction if the tooth cannot be saved
Antibiotics when necessary
Prompt treatment often prevents tooth loss and serious complications.
