Facial swelling is never something to ignore, especially when it’s linked to a toothache or gum problem. In many cases, swelling is caused by a tooth infection or dental abscess, which can quickly become serious if left untreated. At Preston Dental Group, we often see patients who aren’t sure whether they should head straight to the hospital or book an appointment with their local dentist Preston. This blog explains what you need to know, the signs to watch for, and when to seek emergency dental care.

What Causes Facial Swelling from a Tooth Infection?

Facial swelling usually happens when bacteria spread from an infected tooth or gum tissue into the surrounding areas of the mouth, jaw, or face. Common causes include:

1. Untreated tooth decay that has reached the nerve (pulp) of the tooth

2. Gum infections (periodontal disease) that worsen over time

3. Trauma to a tooth that exposes it to bacteria

4. Failed dental treatments or previous infections that flare up again

When the infection spreads, the body responds with inflammation, which is why you notice redness, swelling, and pain.

When Should You Worry About Swelling?

Not all swelling means an emergency, but if you notice the following symptoms, you should call a Preston dentist right away:

1. Rapidly increasing swelling in your cheek, jaw, or face

2. Pain that doesn’t ease with over-the-counter medication

3. Difficulty swallowing or breathing

4. Fever or feeling generally unwell

5. Swelling that spreads toward your eye or neck

These symptoms can indicate a severe infection that requires urgent attention.

Should You Go to the Dentist or Hospital?

A common question patients ask is: “If I have swelling, should I see my dentist or go straight to the hospital?”

1. See your dentist first – Most dental infections are best treated by a dentist who can remove the source of infection and relieve your pain.

2. Go to the hospital – If swelling is making it hard to breathe, swallow, or is spreading rapidly, you should go to the emergency department right away, as this can be life-threatening.

At Preston Dental Group, we provide same-day emergency appointments, so in most cases, contacting your Preston dentist is the safest and fastest option.

Treatment Options for a Tooth Infection

Your dentist will assess the infection and recommend the most appropriate treatment, which may include:

1. Antibiotics to reduce the spread of infection (not a permanent solution, but important in urgent cases).

2. Drainage of the abscess to relieve pressure and pain.

3. Root canal therapy to clean out the infected tooth and save it where possible.

4. Tooth extraction if the infection is severe and the tooth cannot be restored.

The goal is to treat both the infection and its source, ensuring you get relief while preventing future issues.

What You Can Do at Home Before Seeing a Dentist

While waiting for your appointment, here are a few steps you can take:

1. Rinse your mouth gently with warm saltwater to ease discomfort.

2. Apply a cold compress to the outside of your cheek to help reduce swelling.

3. Take pain relief (as directed) to manage discomfort.

4. Avoid pressing on the swollen area or attempting to drain it yourself.

These measures may provide temporary relief, but they won’t cure the infection. Only a dentist can provide the treatment you need.

Preventing Tooth Infections in the Future

The best way to avoid dental infections and facial swelling is through preventive care. A few simple steps include:

1. Regular check-ups with your Preston dentist (usually every 6 months).

2. Brushing twice daily with fluoride toothpaste.

3. Daily flossing to remove bacteria between teeth.

4. Reducing sugary foods and drinks that contribute to decay.

5. Wearing a mouthguard if you play contact sports to prevent trauma.
