What Should I Do If My Face Is Swollen From a Tooth?

If your face is swollen from a tooth, call a dentist promptly for guidance, especially if the swelling is new, worsening, painful, or connected to a toothache. Facial swelling can happen when a tooth infection, dental abscess, gum infection, or damaged tooth causes inflammation or infection to spread beyond the tooth area.

Go to the emergency room right away if the swelling is severe, spreading quickly, affecting your breathing or swallowing, spreading toward the eye or neck, or happening with fever or feeling very ill. These symptoms may suggest the infection is becoming more serious and needs urgent medical evaluation first.

Why Can a Tooth Cause Facial Swelling?

Facial swelling from a tooth often means infection or inflammation is no longer limited to the inside of the tooth. Bacteria may spread from a deep cavity, cracked tooth, failed dental work, gum infection, or abscess near the root of the tooth.

A tooth infection can sometimes cause pain, pressure, gum swelling, a bad taste, drainage, or swelling in the cheek, jaw, or face. If you want a broader explanation of symptoms and treatment options, visit our Tooth Infection page.

When Facial Swelling Needs the Emergency Room

Some facial swelling should not wait for a dental appointment. Go to the emergency room right away if swelling from a tooth is associated with:

• Trouble breathing
• Trouble swallowing
• Swelling spreading into the neck, under the jaw, or toward the eye
• Severe facial swelling
• Fever with facial swelling
• Difficulty opening your mouth
• Confusion, weakness, dehydration, or feeling very ill
• Rapidly worsening symptoms

These warning signs may suggest that an infection is spreading beyond the tooth. If swelling affects breathing or swallowing, or if facial swelling occurs with fever and you cannot reach a dentist, emergency medical care may be needed.

When to Call an Emergency Dentist First

If the swelling is centered near a tooth or gum area and you do not have major medical danger signs, calling an emergency dentist is often the right first step.

Call a dentist promptly if you have:

• Swelling near one painful tooth
• A gum bump or pimple near the tooth
• Bad taste or drainage
• Pain when biting
• Severe tooth pain
• A cracked, broken, or heavily decayed tooth
• Swollen gums near the tooth

If you are unsure whether the swelling should be handled by a dentist or the emergency room, our Emergency Dentist vs. Emergency Room page explains how to decide.

Can I Wait to See If the Swelling Goes Down?

It is not a good idea to ignore facial swelling from a tooth. Even if pain improves, the infection source may still be present. Sometimes swelling or drainage can temporarily reduce pressure, but that does not mean the tooth infection is gone.

Waiting can allow the infection to worsen, spread, or make treatment more complicated. If your face is swollen and you think it may be coming from a tooth, call for guidance as soon as possible.

Will Antibiotics Fix Facial Swelling From a Tooth?

Antibiotics may be recommended in some situations, especially if swelling is spreading or there are medical concerns. However, antibiotics alone usually do not remove the dental source of the infection.

If the infection is coming from inside the tooth, treatment may involve root canal treatment if the tooth can be saved. If the tooth is too damaged, cracked, or unsupported, tooth extraction may be needed instead.

How a Dentist Checks Facial Swelling From a Tooth

A dentist may check the swollen area, the tooth, gums, bite tenderness, drainage, dental X-rays, and nearby bone support. The goal is to determine whether the swelling is coming from the tooth, gums, trauma, a crack, existing dental work, or another source.

Personal insight: In our office, facial swelling changes the urgency of the conversation. We want to know where the swelling is, how quickly it is changing, whether the patient has fever, and whether there is any trouble breathing or swallowing before deciding the safest next step.

So, What Should You Do If Your Face Is Swollen From a Tooth?

If facial swelling is mild and centered around a tooth or gums, call a dentist promptly. If swelling is severe, spreading quickly, affecting the neck or eye area, or happening with fever, trouble swallowing, trouble breathing, or feeling very ill, go to the emergency room right away.

After the urgent symptoms are addressed, dental treatment may still be needed to treat the source of the infection. If you are not sure what to do, call for guidance so the situation can be triaged appropriately.
