can dental x rays cause brain tumors?

April 10, 2012 -- Getting frequent dental X-rays appears to increase the risk for a commonly diagnosed brain tumor, a new study finds. Exposure to ionizing radiation -- the kind found in X-rays -- is the biggest known environmental risk factor for largely non-malignant meningioma brain tumors.

Ask both dentists to help you with forwarding your X-rays. Dental X-ray exams are safe; however, they do require very low levels of radiation exposure, which makes the risk of potentially harmful effects very small.

CT scans expose you to radiation. A CT scan uses X-rays to create images of the brain and skull. X-rays are a form of radiation which increases the risk of cancer over your lifetime. Risks from radiation exposure add up, so it is best to avoid unnecessary radiation when possible.

People who have undergone radiation therapy as a treatment for leukemia, fungal infections of the scalp or previous cancers of the brain have an elevated risk of developing glioblastoma. Other risk factors include being male, being 50 years of age or older and having chromosomal abnormalities on chromosome 10 or 17.

X-rays can also be used to detect dead nerves in teeth. Although x-rays cannot provide an image of soft tissue, once the dead nerve has caused damage to the bone surrounding the apex, or tip, of the root, it can be spotted on an x-ray film.

Some people worry that X-rays aren't safe because radiation exposure can cause cell mutations that may lead to cancer. The amount of radiation you're exposed to during an X-ray depends on the tissue or organ being examined.

The tooth could become infected and the infection could spread to the head and neck, causing serious health problems such as an abscess. Dental insurance can ensure your child's chipped or cracked tooth is addressed by your dental professional quickly before it has a chance to turn into a more serious problem.

Ionising radiation may cause damage to the cells in your body. This is usually very minor and does not cause any serious damage, however, large doses may cause the cells to become cancerous. A very low dose x-ray, such as a chest x-ray, has a tiny risk.

X-rays can often detect damage to the bones caused by cancer, or new bone that's growing because of cancer. They can also determine whether your symptoms are caused by something else, such as a broken bone (fracture).

Headaches may also be side effects of spinal cord tumors, pituitary gland tumors, upper throat/nasopharyngeal cancer , as well as non-Hodgkin lymphoma, advanced-stage lung cancer and primary brain lymphomas.

X-rays are most often used to examine bones and teeth. Magnetic resonance imaging uses radio waves and a magnetic field to create more detailed pictures of the inside of the body. This type of imaging is used to find tumors and other abnormalities in tissues that won't show up in X-rays.

X-rays of the skull may be done to diagnose fractures of the bones of the skull, birth defects, infection, foreign bodies, pituitary tumors, and certain metabolic and endocrine disorders that cause bone defects of the skull.

Their most common locations are the base of the skull and the lower portion of the spine. Although these tumors are benign, they may invade the adjacent bone and put pressure on nearby neural tissue.

These tests use x-rays, strong magnets, or radioactive substances to create pictures of the brain and spinal cord. Magnetic resonance imaging (MRI) and computed tomography (CT) scans are used most often to look for brain diseases. These scans will almost always show a brain tumor, if one is present.

An X-ray of the aching tooth can help identify an abscess. Your dentist may also use X-rays to determine whether the infection has spread, causing abscesses in other areas.

Are dental x-rays really necessary? yes. many diseases and conditions that cannot be detected by looking in the mouth (tooth decay , gum disease, cysts, tumors). They may also not provide signs or symptoms and may go unnoticed for a long time.

Since x-rays use ionizing radiation, they can cause damage to our cells and DNA. X-ray tests can lead to cancer, but several common tests (such as mammograms and bone x-rays) use very low doses that have not been shown to cause a significant increased risk of cancer when administered properly.
