How to Manage a Tooth Infection Before It Gets Worse

A tooth infection isn’t something you can ignore. What starts as mild discomfort can quickly turn into severe pain, swelling, or even a dental emergency if left untreated. In New Zealand, dental care can be costly and difficult to access at short notice, which means many people aren’t sure what to do when symptoms first appear.

The good news is that early action makes a huge difference. If you recognise the signs of a tooth infection and know how to manage it safely, you can prevent complications and get the right treatment before things escalate.

What Is a Tooth Infection?

A tooth infection (also known as a dental abscess) happens when bacteria enter the tooth or surrounding tissues. This usually occurs when decay, cracks, or gum disease create an opening for bacteria to spread.

Once inside, the bacteria can cause:

• Pus buildup

• Swelling

• Pressure

• Pain

• Fever

• Inflammation

Infections may develop inside the tooth, at the root, or in the gums. All forms require prompt attention.

Common Signs of a Tooth Infection

You may be dealing with an infection if you notice:

• Throbbing or sharp tooth pain

• Swollen gums or face

• Sensitivity to hot or cold

• A bad taste in the mouth

• Difficulty chewing

• Fever or chills

• A pimple-like bump on the gums

• Pain that radiates to the ear or jaw

These symptoms often worsen over time. If swelling spreads to the face, eye area, or neck, this can be serious — seek urgent medical care.

Why You Shouldn’t Ignore a Tooth Infection

Dental infections don’t resolve on their own. Without treatment, the bacteria can spread deeper into the jaw, sinuses, or bloodstream. This can lead to:

• Severe swelling

• Tooth loss

• Bone infection

• Sepsis (a medical emergency)

Catching the infection early prevents these complications and reduces the need for more invasive treatment.

Immediate Steps You Can Take

If you suspect a tooth infection, here’s what you can do right away:

1. Manage Pain and Swelling

Over-the-counter pain relief such as paracetamol or ibuprofen can help reduce discomfort. A cold compress against the cheek may also help calm swelling.

2. Keep the Area Clean

Rinse with warm salt water several times a day. This doesn’t cure the infection but can soothe irritation and help control bacteria.

3. Avoid Aggravating the Tooth

Try to chew on the opposite side of your mouth. Avoid very hot, very cold, or sugary foods that may worsen the pain.

4. Don’t Attempt Home Draining

Never try to pop or drain an abscess yourself. This can push bacteria deeper and cause a dangerous spread of infection.

When to See a GP vs a Dentist

A dentist ultimately needs to treat the source of the infection — usually through draining the abscess, performing a root canal, or removing the tooth.

However, a GP can help you manage the infection early, especially if you can’t access a dentist immediately.

A GP can provide:

• An assessment of your symptoms

• Antibiotics if clinically appropriate

• Advice on pain management

• Guidance on when urgent dental care is needed

If your infection is spreading or you have fever, difficulty swallowing, or facial swelling, you can schedule an online tooth infection treatment with Pocket Lab to prevent further complications.

When Antibiotics Are Needed

Antibiotics are often recommended when:

• There is significant swelling

• The infection is spreading

• You have fever or systemic symptoms

• You cannot see a dentist right away

They help control the infection but won’t resolve the underlying tooth issue. You will still need dental follow-up as soon as possible.

Pocket Lab makes it easy to access fast care if you need early medical advice or an antibiotic prescription while arranging dental treatment.

Home Remedies That Don’t Work

It’s common for people to try various remedies found online, but many are ineffective or risky. Avoid:

• Applying aspirin directly to the gum

• Using alcohol or hydrogen peroxide

• Pressing or squeezing the swollen area

• Relying solely on painkillers long-term

These won’t eliminate the infection and may worsen irritation.

How to Prevent Future Tooth Infections

Good dental hygiene significantly reduces the chance of infection. Prevention includes:

• Brushing twice daily

• Daily flossing

• Limiting sugary foods and drinks

• Replacing your toothbrush regularly

• Seeing a dentist for routine checks

• Treating cavities or gum issues early

Even with great care, infections can happen — especially if you grind your teeth, have damaged fillings, or have a weakened immune system. Knowing the signs helps you act early.

When to Seek Urgent Medical Help

Get immediate care if you notice:

• Severe swelling affecting the face or neck

• Difficulty swallowing or breathing

• Fever and chills

• Rapidly spreading redness

• Vision changes (rare but serious)

These symptoms can indicate a more serious infection that needs urgent treatment.

Take the First Step Toward Treatment

A tooth infection can become serious quickly — but early action can prevent major pain, costly procedures, and long-term damage. If you’re experiencing symptoms and need fast support, Pocket Lab’s online GPs can assess your infection, provide guidance, and prescribe antibiotics if appropriate while you arrange dental care.

Getting help early is the best way to stop a tooth infection from getting worse.
