A dental infection is one of the most serious oral health situations you can face — and it should never be left untreated. If you’re experiencing intense tooth pain, swelling in your jaw or face, or a fever alongside a toothache, seeking emergency dental care as soon as possible could protect both your oral health and your overall wellbeing.
What Is a Dental Infection?
A dental infection, often called a dental abscess, occurs when bacteria invade the inner tissue of a tooth, the surrounding gum, or the bone. This typically happens when tooth decay goes untreated, when a tooth is cracked or broken, or when gum disease has progressed to a serious stage. The infection creates a pocket of pus that can cause significant pain and, if left alone, can spread to other parts of the body — including the jaw, neck, or even the brain in severe cases.
The two most common types of dental abscesses are:
- Periapical abscess: An infection at the tip of the tooth root, usually stemming from untreated decay or a damaged pulp.
- Periodontal abscess: An infection in the gum tissue beside the root, often linked to periodontal (gum) disease.
Warning Signs You Need Emergency Dental Care
Some dental discomfort can wait a day or two for a scheduled appointment — but not a dental infection. You should contact an emergency dentist in NW Calgary right away if you experience any of the following:
- Severe, throbbing toothache that doesn’t subside with over-the-counter pain relief
- Swelling in the face, cheek, or jaw that is worsening
- Fever, chills, or general illness alongside tooth or jaw pain
- Difficulty swallowing or breathing — this requires an immediate visit to the emergency room
- A pimple-like bump on the gum that may be oozing or tender
- Sensitivity to hot or cold that lingers long after the temperature change
If you notice swelling in your neck or throat, or if you have any difficulty breathing, go directly to the nearest emergency room, as this may indicate the infection is spreading rapidly.
How Dental Infections Are Treated
The treatment for a dental infection depends on its severity and location. Your dentist will assess the situation — often using digital X-rays to see exactly how far the infection has spread — and recommend the most appropriate approach. Common treatments include:
- Root canal treatment: If the infection is inside the tooth, a root canal in Calgary NW can remove the infected pulp, clean the canals, and save the tooth. Many patients are surprised by how comfortable this procedure is with modern techniques.
- Tooth extraction: In cases where the tooth cannot be saved, removing it stops the infection from spreading. Your dentist can discuss replacement options such as dental implants or bridges afterward.
- Drainage of the abscess: Your dentist may need to make a small incision to drain the pus and relieve pressure.
- Antibiotics: These are often prescribed to help clear the infection, especially if it has begun to spread. However, antibiotics alone cannot cure a dental abscess — the source of the infection must also be treated.
What to Do While You Wait for Your Appointment
If you can’t get to a dentist immediately, there are a few steps you can take at home to manage your discomfort:
- Rinse gently with warm salt water several times a day to help reduce bacteria and soothe irritated tissue.
- Take over-the-counter pain relievers such as ibuprofen or acetaminophen as directed on the packaging.
- Avoid very hot or very cold foods and beverages, which can intensify sensitivity.
- Sleep with your head slightly elevated to help reduce swelling.
These measures are temporary relief only. They do not treat the infection — only a licensed dental professional can do that.
Preventing Dental Infections in the First Place
While emergencies can happen to anyone, many dental infections are preventable with consistent oral care. Brushing twice daily, flossing regularly, and attending routine check-ups and cleanings are your best defence. For Calgary families, establishing a relationship with a trusted dental practice through ongoing family dental care in Calgary NW means any signs of decay or gum disease can be caught and treated early — well before they develop into emergencies.
If it’s been a while since your last cleaning, don’t wait. Early intervention is always easier, less costly, and far less stressful than emergency treatment.

Frequently Asked Questions
How do I know if my toothache is a dental infection?
A toothache caused by infection is usually more intense and persistent than typical tooth sensitivity. Signs that point to an abscess include throbbing or pulsating pain, swelling in the face or jaw, a bad taste in your mouth, fever, and a bump on the gum near the sore tooth. If you’re experiencing any of these, contact an emergency dentist right away.
Can a dental infection go away on its own?
No — a dental abscess will not resolve on its own. While the pain may temporarily subside if the abscess ruptures, the underlying infection remains and will continue to spread. Without professional treatment, a dental infection can become life-threatening. Always see a licensed dentist as soon as possible.
Will I need a root canal if I have a dental infection?
Not always — it depends on the type and severity of the infection. If the infection has reached the inner pulp of the tooth, a root canal is often the best option to save the tooth and eliminate the infection. In other cases, drainage, antibiotics, or an extraction may be more appropriate. Your dentist will recommend the right course of treatment after a thorough examination.
Are antibiotics enough to treat a dental infection?
Antibiotics can help control and reduce a dental infection, especially if it has spread, but they cannot cure an abscess on their own. The source of the infection — whether it’s an infected tooth pulp or a gum pocket — must be physically treated by a dentist. Relying solely on antibiotics without dental treatment allows the infection to return.
What should I do if my face is swollen from a tooth infection?
Facial swelling from a dental infection is a serious symptom that requires urgent care. Contact an emergency dentist immediately. If the swelling is affecting your ability to breathe or swallow, or if you have a high fever, go to the nearest emergency room or call 911 right away, as these are signs the infection may be spreading to critical areas.
How can I prevent dental abscesses?
The best prevention is consistent oral hygiene — brushing twice a day, flossing daily, and attending regular dental check-ups and professional cleanings. Treating cavities and cracks early, before they reach the tooth pulp, significantly reduces your risk of developing an abscess. A good relationship with your family dental clinic makes it easier to catch problems early.
