Do dentist x-rays penetrate the brain and is it harmful?

Dental X-rays do not penetrate the brain and are not harmful to the brain.

Dental X-rays use a very small amount of radiation to take images of the teeth and jaw. The amount of radiation used in a dental X-ray is very low and is considered safe for both adults and children.

The X-rays used in dentistry are carefully controlled to minimize the amount of radiation exposure. Dental X-rays are also shielded to protect the face, neck, and other parts of the body from unnecessary radiation.

While dental x-rays are not harmful to the brain, it's important to take only the necessary x-rays and to follow the recommended guidelines for frequency.
