Tooth infections are common, but they can become very serious if left untreated. A dental abscess, which is an infection at the root of a tooth, can sometimes spread beyond the tooth and affect other parts of your body. In rare cases, the infection can even reach the brain. This is why it’s important to recognise the signs early and seek help from an NHS dentist in Aberdeen or doctor. Let’s explore how to know if a tooth infection has spread to the brain.
What is a Tooth Infection?
A tooth infection, also known as a dental abscess, happens when bacteria get inside the tooth or gum. This can occur due to untreated cavities, gum disease, or damage to the tooth. The infection causes pus to build up, which can lead to swelling, pain, and discomfort.
If the infection isn’t treated, the bacteria can spread to the jaw, neck, and even other parts of the body. In rare cases, it can spread all the way to the brain, causing a serious condition called a brain abscess.

Common Signs of a Tooth Infection
Before we talk about the signs of an infection spreading to the brain, let’s go over the usual symptoms of a tooth infection. These signs are often easy to notice and should never be ignored:
- Severe tooth pain: This pain is usually sharp and throbbing, and it might get worse when chewing or touching the affected tooth.
- Swelling: You may notice swelling in your cheek, jaw, or gum around the infected tooth.
- Fever: A fever can happen when the infection spreads in your body.
- Bad taste or odour: This occurs when pus from the infection leaks into the mouth.
- Sensitivity: Your tooth might hurt more when exposed to hot or cold food or drinks.
- Difficulty swallowing: As the infection spreads, it can make swallowing difficult.
If you notice these signs, you should see a dentist as soon as possible. The longer the infection is left untreated, the higher the chance it will spread to other parts of your body, including the brain.

How a Tooth Infection Spreads to the Brain
In some cases, a tooth infection can spread beyond the tooth and reach the brain. This usually happens when the bacteria travel through the bloodstream or the sinus areas near the upper teeth. The infection can also spread from the jaw or neck area, moving through the tissues to the brain.
A brain abscess occurs when the bacteria from the tooth infection create a pocket of pus in the brain. This is a serious condition and needs immediate medical treatment. However, brain abscesses caused by tooth infections are very rare.
Signs That a Tooth Infection Has Spread to the Brain
When a tooth infection spreads to the brain, the symptoms become much more serious. Recognising these signs early can help you get treatment before the situation worsens. Some of the main signs that a tooth infection has spread to the brain include:
- Severe headaches
One of the first signs of a brain abscess is a persistent, severe headache that doesn’t go away with normal painkillers. The headache may get worse over time. - Neck stiffness
If you notice that your neck feels stiff and painful, this could indicate that the infection has spread to the brain. Stiff neck muscles are often a sign of meningitis, which can happen alongside a brain abscess. - Fever and chills
If you have a fever that won’t go away, along with chills and excessive sweating, it may suggest that the infection has spread to the bloodstream and brain. - Nausea and vomiting
Nausea and vomiting can occur when the infection increases pressure inside the skull, affecting brain function. - Sensitivity to light
If you become unusually sensitive to light or your eyes hurt when exposed to bright light, this could be a symptom of a brain abscess. - Confusion and dizziness
Feeling dizzy, confused, or disoriented can be a sign that the infection is affecting brain function. You might also feel unusually tired or fatigued. - Neurological symptoms
In some cases, you might experience other neurological symptoms, such as difficulty speaking, numbness, or weakness in your muscles. These symptoms can indicate that the infection has spread to a specific area of the brain. - Seizures
Although rare, some people with a brain abscess experience seizures, which are sudden, uncontrolled movements caused by abnormal electrical activity in the brain.

What to Do If You Think Your Tooth Infection Has Spread to the Brain
If you suspect that your tooth infection has spread to the brain, it’s essential to get medical help immediately. A brain abscess can be life-threatening if not treated quickly. Here’s what you should do:
- Seek immediate medical attention
Go to the nearest hospital or emergency room as soon as possible. A brain abscess requires urgent care, often involving antibiotics and possibly surgery to drain the abscess. - Consult your dentist
While you may need to see a doctor for the brain abscess, you should also consult your dentist to treat the original tooth infection. They can help you address the underlying problem, preventing further complications. - Get imaging tests
Doctors will use imaging techniques such as CT scans or MRIs to check for a brain abscess. These tests can confirm if the infection has spread to the brain. - Follow the treatment plan
Treatment for a brain abscess typically involves a combination of antibiotics and, in some cases, surgery to remove the pus from the brain. Follow your doctor’s instructions carefully to ensure proper recovery.

Prevention of Tooth Infections
The best way to avoid the dangers of a tooth infection spreading to the brain is to prevent infections in the first place. Here are a few simple tips to keep your teeth healthy and reduce the risk of infection:
- Brush your teeth twice a day with fluoride toothpaste.
- Floss daily to remove plaque between your teeth.
- Limit sugary foods and drinks, as sugar can cause tooth decay.
- Visit your dentist regularly for checkups and cleanings.
- Treat cavities and gum disease early to prevent infection.
By maintaining good oral hygiene and seeking dental care when needed, you can greatly reduce your risk of developing a serious tooth infection.
