How An Abscessed Tooth Can Damage Your Overall Health

Encephalitis – brain inflammation – Symptoms, causes, prognosis, Treatment. explained simply

Is an abscessed tooth dangerous? Can an abscessed tooth cause sepsis? Canker sores? We hear a lot of these questions from folks who suspect they have an abscessed tooth, and want to know how important it is to get treatment sooner rather than later.

So is an abscessed tooth an emergency? Its not an immediate emergency in the way that a tooth fraction would be. But it is serious. If left untreated, an abscessed tooth can have a severely negative impact on your overall health.

A Diagnostic Test Based On Cytokine Profile Could Help Distinguish Between Infection And Other Diseases

PHILADELPHIA When patients present with neurologic symptoms such as severe headaches or seizures, the symptoms could suggest anything from infection, cancer, or an autoimmune disease of the brain or spinal cord, leaving physicians scrambling to find the cause in a short amount of time. The differences in diagnosis can mean having mere hours to act or being able to take days or weeks to devise a treatment plan. Now, researchers at Jefferson have developed a test that could rapidly parse out infections of the brain from other diseases. The diagnostic could prove particularly useful in infants and young children.

We have many tests for making diagnoses, but the ones that conclusively indicate infection can often take more time than wed like, especially in cases of childhood meningitis or encephalitis, said , MD, PhD, Associate Professor of Pathology, Anatomy and Cell Biology, who also works as a hospital pathologist. Once confirmed with additional research, our test could provide a first, rapid and less invasive way to look at whats happening in the brain and guide treatment or further testing.

The results were published in the journal PLOS ONEon October 31.

Additionally, within the patients identified with central nervous system infections, the CSF cytokine fingerprint was different in cases of viral infection compared to those with non-viral pathogens, such as bacteria or fungi.

Can A Fungal Ear Infection Spread

ear infectionscanspreadcanear infectionscanear infection

An infection can spread from a nearby area, and this accounts for 1458 percent of brain abscesses. If an infection starts inside the skull, for example in the nose or the ear, it can spread to the brain. Infections that can trigger a brain abscess include: otitis media, or a middle ear infection.

Subsequently, question is, how do you get rid of fungus in your ear? You may need to use antifungal ear drops to treat otomycosis. They may include clotrimazole and fluconazole. Acetic acid is another common treatment for otomycosis. Usually, a 2 percent solution of these ear drops is used several times a day for about a week.

Also question is, how long does it take for a fungal ear infection to go away?

Treatment of otomycosis includes microscopic suction clearance of fungal mass, discontinuation of topical antibiotics and treatment with antifungal ear drops for three weeks. Ear should be kept dry for three weeks. Small perforations heal spontaneously and larger perforation requires myringoplasty.

What causes a fungal ear infection?

Share on Pinterest Otomycosis can cause hearing loss and a feeling of fullness in the ear. Otomycosis is an infection caused by a fungus. There are several different types of fungus that can cause this infection, but most otomycosis infections are related to Aspergillus species or, less commonly, Candida.

How Do Infections Get In Your Brain

Infections usually start somewhere else. They can get to your brain and meninges in several ways:

  • From an infection nearby, such as in your teeth, sinuses, or ears

  • Through your blood from another part of your body

  • Directly from the outside, for example, through a skull fracture or during brain surgery

Infections that spread through your blood sometimes come from bug bites, particularly from mosquitoes and ticks.

Fungal Infection In The Brain: What We Learned From Intravital Imaging

Approximately 1.2 billion people suffer from fungal diseases worldwide. Arguably, the most serious manifestation occurs when pathogenic fungi infect the brain, often causing fatal meningoencephalitis. For most fungi, infection occurs via the vascular route. The organism must first be arrested in the brain microvasculature and transmigrate into the brain parenchyma across the bloodbrain barrier. As a result, host immune cells are recruited into the brain to contain the fungi. However, it remains poorly understood how fungi traffic to, and migrate into the brain and how immune cells interact with invading fungi in the brain. A new era of intravital fluorescence microscopy has begun to provide insights. We are able to employ this powerful approach to study dynamic interactions of disseminating fungi with brain endothelial cells as well as resident and recruited immune cells during the brain infection. In this review, with a focus on Cryptococcus neoformans, we will provide an overview of the application of intravital imaging in fungal infections in the brain, discuss recent findings and speculate on possible future research directions.

Can Meningitis And Encephalitis Be Prevented

People should avoid sharing food, utensils, glasses, and other objects with someone who may be exposed to or have the infection. People should wash their hands often with soap and rinse under running water.

Effective vaccines are available to prevent Haemophilus influenza, pneumococcal and meningococcal meningitis.

People who live, work, or go to school with someone who has been diagnosed with bacterial meningitis may be asked to take antibiotics for a few days as a preventive measure.

To lessen the risk of being bitten by an infected mosquito or other arthropod, people should limit outdoor activities at night, wear long-sleeved clothing when outdoors, use insect repellents that are most effective for that particular region of the country, and rid lawn and outdoor areas of free-standing pools of water, in which mosquitoes breed. Repellants should not be over-applied, particularly on young children and especially infants, as chemicals such as DEET may be absorbed through the skin.

Symptoms That Sinusitis Has Spread To The Brain

Do you Have a Parasite Infection?

A patient experiences severe symptoms when the sinusitis spreads and reaches to the brain. Some of the symptoms including-

  • Changes in vision
  • Difficulty speaking
  • Severe headache inside the skull

However, our Pristyn Care ENT specialist explains that headaches can be a symptom of migraine or pressure build up inside the skull that irritates the brain lining. Another cause of headaches could be brain infection. However, if there is an infection in the brain there can be other symptoms.

Tooth Infection Treatment Options

Depending on the cause of the tooth infection, treatment may include:

Dental Abscess Treatment

During this procedure, your dentist will make a small incision into your gums and drain the abscess. They will drain all of the pus out before stitching it back up to ensure the bacteria is removed. If your tooth is severely damaged or decayed, extraction will likely be necessary. Youll need a dental implant after the tooth is surgically removed, which can cost up to $4,000.

Root Canal Treatment

Root canal treatment is necessary if you have a large cavity that has spread to the tooths pulp. This treatment can also involve abscess draining. During the procedure, your dentist will remove the infected dental pulp and drain the abscess. The root canal is cleaned, shaped, and sealed. Then a dental crown is placed on top of the root canal treated tooth.


Antibiotics are commonly prescribed to treat dental abscesses. After the abscess is drained, your dentist may prescribe antibiotics to clear up the remaining infection. Antibiotics alone do not cure abscesses. Depending on the severity of your abscess or infection, you may need oral antibiotics or IV antibiotics.


Three common treatment options for tooth abscesses include drainage , root canal treatment, and antibiotics.

How The Sinus Infection Spreads To The Brain

Although there are various barriers that protect the brain from various pathogens, sometimes bacteria can pass through. The reason is that the space between the sinuses and the brain is very less making it easy for the pathogens to spread. If the infection spreads and infects the brain, it can lead to swelling, seizures, vomiting and abnormal mental health.

Hence, for people looking for the answer to the question can sinusitis lead to brain infection- YES, it can. But remember, only in rare instances this occurs. The likelihood of a patient dying from this condition is very low.

What Types Of Tests Might I Need

Testing helps healthcare providers:

  • Determine how severe it is.
  • Identify the type of encephalitis .

Tests you may need include:

  • Lumbar puncture , which involves taking a sample of spinal fluid and examining it in a lab.
  • Blood tests, which assess organ functioning and check for specific types of bacteria.
  • Imaging studies, such as a CT scan, MRI and MEG test. These tests show signs of tissue damage. They can also detect issues like tumors and brain bleeds.

What Causes Meningitis And Encephalitis

Everything You Need To Know About Candidiasis Blood

Infectious causes of meningitis and encephalitis include bacteria, viruses, fungi, and parasites. For some individuals, environmental exposure , recent travel, or an immunocompromised state are important risk factors. There are also non-infectious causes such as autoimmune/rheumatological diseases and certain medications.


Bacterial meningitis is a rare but potentially fatal disease. Several types of bacteria can first cause an upper respiratory tract infection and then travel through the bloodstream to the brain. The disease can also occur when certain bacteria invade the meninges directly. Bacterial meningitis can cause stroke, hearing loss, and permanent brain damage.

Other forms of bacterial meningitis include Listeria monocytogenes meningitis Escherichia coli meningitis, which is most common in elderly adults and newborns and may be transmitted to a baby through the birth canal and Mycobacterium tuberculosis meningitis, a rare disease that occurs when the bacterium that causes tuberculosis attacks the meninges.

Fungal infections can affect the brain. The most common form of fungal meningitis is caused by the fungus cryptococcus neoformans . Cryptococcal meningitis mostly occurs in immunocompromised individuals such as those with AIDS but can also occur in healthy people. Some of these cases can be slow to develop and smolder for weeks. Although treatable, fungal meningitis often recurs in nearly half of affected persons.

Longer Term Effects Of Inner Ear Infections

Generally, the symptoms will clear up as soon as the infection is gone. However, the effects can sometimes last longer.

You might still feel dizzy and off-balance even when the other symptoms caused by the infection have gone. This can be a sign that the balance organs were damaged. Your brain can usually learn to work with these changes, so your sense of balance should usually come back by itself. However, if youre struggling to cope or the problem persists, you should see an ENT specialist. The doctor can check for any underlying causes and may refer you for vestibular rehabilitation therapy to help you to recover your balance.

Inner ear infections can also have a longer term effect on your hearing. This is more likely if you had bacterial infection, so your doctor might recommend a hearing test to check on your ears after the infection.

How To Prevent Endocarditis From The Dental Infections

Endocarditis can be prevented from dental infections by regularly brushing teeth along with flossing with regular visits to dental professionals for timely scaling to prevent any gum infection.

Periodontitis is found to be a risk factor for diabetes and coronary artery disease. It is estimated that about 30% deaths around the world is due to cardiovascular disease. Therefore, measures should be taken to prevent cardiovascular disease with a healthy lifestyle, exercising, weight control and cessation of smoking. It is also important to keep oral hygiene and measures should be taken to prevent and treat dental infections. Since they are most of the times asymptomatic, but very common, regular dental visit is necessary for early identification and treatment to avoid progression of infection and need for root canal treatment. If RCT is indicated then it should be done without any second thought as this might lead to probability of a heart disease.

Antibiotic treatment is recommended in patients who already have a history of endocarditis, since it makes them more susceptible for further endocarditis prosthetic valve or the use of prosthesis in the repair of cardiac valve congenital heart disease and/or cardiac transplant.

You Feel More Down Than Usual

When your brain is inflamed you may also experience depression. Again, this type of inflammation is usually lifestyle-related. As Health Coach and a Nutritional Therapist, Christina Tsiripidou tells Bustle, eating meals that are high in toxic protein or proteins that are genetically modified, and low in vegetables and healthy fats, can contribute to this. Not getting enough sleep and poor stress management skills can also have a way of making this worse.

What Research Is Being Done

Toxoplasmosis: How Parasites in Your Cat Can Infect Your Brain

The mission of the National Institute of Neurological Disorders and Stroke is to seek fundamental knowledge about the brain and nervous system and to use that knowledge to reduce the burden of neurological disease. The NINDS is a component of the National Institutes of Health , the leading supporter of biomedical research in the world.

Current research efforts include basic studies of host immune responses, gaining a better understanding of how the central nervous system responds to inflammation, and the role of T cells in suppressing infection in the brain. Scientists hope to better understand the molecular mechanisms involved in the protection and disruption of the blood-brain barrier, which could lead to the development of new treatments for several neuroinflammatory diseases such as meningitis and encephalitis. Other scientists hope to define, at a molecular level, how certain viruses overcome the bodys defense mechanisms and interact with target host cells. A possible therapeutic approach under investigation involves testing neuroprotective compounds that block the damage that may follow infection and inflammation of meningitis and encephalitis and potentially lead to complications, including loss of cognitive function and dementia. Additional research focuses on autoimmune causes of encephalitis and the optimal treatments for them.

Symptoms Due To Specific Types Of Encephalitis

Encephalitis caused by certain infections or autoimmune processes can show up with characteristic symptoms.

  • A sensation of déjà vu is a common finding in early stages of herpes simplex virus encephalitis.
  • A type of autoimmune encephalitis affecting NMDA receptors can start with a flu-like illness. It can then lead to behavioral changes and unusual movement patterns affecting the mouth and face, cognitive decline and impaired function of the autonomic nervous system.
  • Another type of autoimmune encephalitis is associated with seizures or other abnormal movement of the face or arm.

The symptoms of encephalitis may resemble other problems or medical conditions. Always consult your health care provider for a diagnosis.

How Does Infection From Tooth Spread To Heart

Since dental problems are so common and nearly every individual has plaque around their teeth, which is loaded with bacteria. The plaque is not completely removed with proper brushing also and requires professional intervention. If the plaque is not removed then it might cause inflammation of the gums causing gingivitis and on advancing further leads to periodontitis causing bleeding from gums with even slight brushing or flossing. The bacteria from bleeding gums enter the bloodstream and infect the inner lining of the heart, thus causing endocarditis. Generally, immune system in healthy individuals is enough to eliminate this infection from bloodstream, but in cases with already compromised heart condition these bacteria lodge and multiply in the inner lining of the heart and present with symptoms of fever, fatigue, chills and night sweats, muscle/joint pain.
