Dental xrays

Dental xrays

Why are x-rays necessary?

Dental x-rays are taken as a preventative measure or to diagnose dental problems. If you have toothache, x-rays help identify the problem.They show what is happening between teeth, under fillings, below the gumline. It is also possible to see the jaw bones and sinus areas. Infections, abscesses, decay, bone loss and unerupted teeth can be viewed on x-rays. Before taking x-rays, the dentist should explain why they are necessary and obtain your consent

What type of x-rays are taken by dentists?

There are several types of dental x-rays. Some show individual teeth while others display all the teeth and parts of your jaw. The most common types are bitewing, periapical and panoramic (OPG) x-rays. If your dentist suspects there may be decay in between teeth or under an existing filling, she will take bitewing or OPG x-rays. Periapical x-rays are often taken in conjunction with root canal treatments to check the root’s length and position.

How does the dentist take x-rays?

You may be covered with a lead apron. Then the dentist will position you correctly and ask you to bite on a small plastic mouthpiece. Finally, your dentist will take an x-ray image of the correct area. This should only take a few moments and will be pain free. You will be able to view digital x-rays immediately. The dentist will point out dental concerns and how to treat them.

Who can take x-rays?

All dentists are trained to take x-rays and have to hold a current radiation use licence. Some dentists may refer patients to a radiology office.

Are x-rays dangerous?

Dental x-rays are one of lowest radiation doses and digital x-rays use very small doses of ionizing radiation. X-ray equipment is tested and maintained regularly to ensure it is operating safely.

Exposure to radiation during pregnancy should be minimised so as to avoid risk to the developing foetus.
