A new study found that people who received frequent dental x-rays before radiation doses were lowered may be at greater risk of developing nonthreatening meningioma brain tumors. Meningioma tumors affect the brain lining and spinal cord, and are benign in over 90% of cases but can grow large enough to impact brain function. The study found those with tumors were over twice as likely to report frequent bitewing x-rays, especially at a young age, and bitewing x-rays which allow views of back teeth use radiation which has been linked to tumor growth.

2.  A new study suggests that people who went
through frequent dental X-rays before radiation
doses were lowered, may be at greater risk of a
usually nonthreatening form of tumor in the lining of
the brain, called meningiomas.
 Dental X-rays use radiation. Radiation is linked to
many types of tumors, including meningiomas. It
isn`t proven that these tumors are linked to dental
X-rays, it`s just a theory.

3.  Meningioma tumors affect the lining of the brain and the
spinal cord. More than 90 percent are classified as
nonthreatening.
 However, in some cases meningiomas can grow to be as big
as a baseball and disrupt the brain's functioning.
 This could cause vision problems, headaches, hearing and
memory loss, and seizures.

4.  Scientists did a survey, those with tumors were more
than twice as likely as the others to report having
more frequent bitewing X-rays (at any time,
especially at a young age).
 Bitewing X-rays allow views of the back teeth;
patients bite onto a tab during the X-rays. This uses
radiation, and can sometimes cause tumors.
