Why Is Jaw Swelling a Dental Emergency?
Swelling in your jaw, cheek, or face that originates from a dental problem means infection has spread beyond the tooth into the surrounding tissues. The swelling itself is your body's inflammatory response to bacteria.
This is not something to watch and wait on. Dental infections can spread rapidly. In the jaw, infection can move into the fascial spaces of the neck, potentially compressing the airway. This condition, called Ludwig's angina, is a genuine medical emergency.
More commonly, spreading infection causes cellulitis, a painful, expanding area of redness and warmth that requires antibiotics and source control (treating the tooth that started it). Without treating the source, antibiotics alone will not resolve the problem.
If your swelling is accompanied by difficulty breathing, difficulty swallowing, fever above 101 degrees, or swelling spreading toward your throat, go to the emergency room immediately. For all other dental swelling, call us at (240) 387-8233.
What Causes Dental Jaw Swelling?
The most common causes of jaw swelling from dental problems include dental abscesses (infection at the root tip of a tooth), pericoronitis (infection around a partially erupted wisdom tooth), advanced gum disease with deep pockets of infection, trauma to the jaw or teeth, and failed previous dental treatment where infection has returned.
Abscesses are the most frequent cause. A tooth with a dead nerve becomes a reservoir for bacteria, and when the infection builds up enough pressure, it breaks through the bone and enters the soft tissue of the cheek or jaw.
Wisdom tooth infections are the second most common cause, particularly in patients between 17 and 25. A partially erupted wisdom tooth creates a pocket that traps food and bacteria, leading to infection and swelling.
How Do We Treat Dental Jaw Swelling?
Treatment targets both the swelling and the source.
For an abscessed tooth causing the swelling: We drain the abscess, which provides rapid relief from pressure and pain. We then either start a root canal to save the tooth or extract the tooth if it cannot be saved. Antibiotics are prescribed if the infection has spread beyond the immediate area.
For wisdom tooth infections: If the wisdom tooth is partially erupted and causing repeated infections, extraction is usually recommended. We clean the infection, prescribe antibiotics if needed, and remove the tooth once the acute swelling has subsided (or immediately, depending on the situation).
For gum infections: Deep cleaning and local antibiotic placement treat the source. Severe cases may require surgical drainage.
The key principle is source control: we treat the tooth or gum condition that caused the infection, not just the symptoms. Antibiotics without source treatment lead to recurring infections.
What to Do While You Wait for Your Appointment
If you are waiting to see us (or heading to our office now), here is what helps:
Apply a cold compress to the outside of your face over the swollen area. Use it for 20 minutes on, 20 minutes off. This can slow the swelling and numb the pain somewhat.
Take ibuprofen (Advil) for pain and inflammation, following the dosage on the package. If you cannot take ibuprofen, acetaminophen (Tylenol) helps with pain but does not reduce inflammation.
Rinse gently with warm salt water several times. This draws some fluid from the swollen tissue and can ease discomfort.
Keep your head elevated, even when sleeping. Lying flat increases blood flow to the head and worsens swelling.
Do not apply heat to the swollen area. Heat increases blood flow and can make the swelling worse. Do not attempt to lance or squeeze the swelling yourself.
Call (240) 387-8233 and describe your symptoms. We prioritize swelling cases and can typically see you the same day.
