Preserve Your Natural Tooth
Root canal therapy removes the infected pulp from inside the tooth, cleans and seals the canal, and preserves the natural tooth. This is the preferred treatment when the tooth can be saved.

Tooth Abscess — A Serious Infection Requiring Urgent Care
A pocket of pus caused by bacterial infection that demands immediate treatment
A tooth abscess is a dental emergency. It is a pocket of pus caused by bacterial infection inside or around a tooth. Without treatment, the infection can spread to the jaw, neck, or other areas of the body.
Call for Emergency Care
A severe, persistent toothache that may radiate to the jawbone, ear, or neck is the primary symptom. You may also experience sensitivity to hot and cold temperatures.
Look for swelling in the face or cheek, fever, a foul taste in the mouth from a draining abscess, and swollen or tender lymph nodes under the jaw. If you have any of these symptoms, seek immediate care.

How Abscesses Develop
Cavities That Reach the Nerve
When cavity decay penetrates deeply into the tooth, bacteria reach the pulp (nerve chamber), causing infection and inflammation. The infected nerve dies, and bacteria begin spreading into the root canal and beyond, into the surrounding bone. This causes severe pain (often described as throbbing or aching) and can lead to facial swelling or a visible bump on the gum. Prompt root canal therapy or extraction is necessary to stop the infection and prevent it from spreading systemically.
Broken Teeth Allow Infection
A cracked or broken tooth creates a pathway for bacteria to enter the pulp chamber directly, bypassing the outer enamel barrier. Trauma from accidents, grinding, or old restorations can crack teeth invisibly, allowing slow bacterial infiltration over weeks or months. Once the nerve is infected, an abscess forms at the root tip, causing pain, swelling, and bone destruction. Early detection and restoration of broken teeth prevents infection; once infection develops, root canal or extraction becomes necessary.
Advanced Periodontal Infection
Untreated gum disease allows bacteria to burrow deeply into bone and root surfaces, eventually reaching the pulp from the side or root tip. This pathway to infection can occur even in teeth that appear intact, making periodontal disease a hidden cause of abscess formation. Advanced periodontal abscesses require coordinated periodontal treatment and endodontic therapy to resolve. Regular periodontal evaluations and treatment prevent the progression to abscess formation and tooth loss.
Treatment Options at Vitality Health
Treatment depends on the location and severity of the infection. Our goal is to eliminate the infection and save your tooth when possible.
Key Details
Most teeth can be saved
Remove the Source of Infection
If the tooth cannot be saved, extraction removes the source of infection and allows the abscess to drain and heal. We discuss replacement options after extraction.

Essential information about this serious condition
If left untreated, yes. The infection can spread beyond the tooth to the jaw, sinuses, brain, or bloodstream. Immediate treatment prevents these serious complications.
No. A tooth abscess requires professional treatment. Home remedies may provide temporary pain relief but cannot eliminate the infection.
Antibiotics manage the infection but cannot cure an abscess. The infected tooth or abscess must be treated — either through root canal therapy or extraction.
Immediately. Contact us at (905) 479-7777. We accommodate emergency cases and can often see you the same day.
The infection will spread, causing increasing pain and potentially serious health complications. Untreated abscesses are dangerous.
