An x-ray of the teeth is often the only way to determine if a tooth infection is present. However, if a tooth infection has spread beyond the tooth, it may not be visible on a regular x-ray. Sometimes an illness is located inside a tooth root, and a dental x-ray can show if an abscess has formed. A dark area may be seen on a dental x-ray, and it can be painful to touch it. If the tooth has lost its vitality, it may not respond to a cold or hot test.
A full-mouth series of periapical X-rays can take 14 to 21 films. A full-mouth series commonly takes 21 films, and bitewing X-rays are used to detect tooth decay. Panoramic x-rays are used occasionally. Your dentist will decide how frequently you need dental X-rays based on your age, risk of disease, and symptoms.
A dental x-ray can also show an abscess, similar to a black void that can be seen on a regular X-ray. The bump may appear small or large, radiolucent, and can even be seen on an x-ray. It may also be present as a blister in the mouth, which indicates long-term infection.
An X-ray can show an abscess when the infection has spread from a tooth to the gums. An x-ray can offer a spot. An abscess will show up as radiolucency on an x-ray. Diseases can interfere with bite occlusion, so your dentist will likely use technical measures to treat the infection. An x-ray can also detect a tooth infection, enabling them to prescribe treatment.
An X-ray may be necessary if a patient is pregnant. An X-ray may not reveal the infection, but it can give a dentist a clearer picture of the condition. For example, a pregnant woman should tell the dentist that she is pregnant. A delayed diagnosis may prove dangerous for the unborn child. In addition to the radiation resulting from a dental x-ray, a pregnant woman can wear a lead collar or a lead apron to protect herself.
Dental x-rays are necessary for the dentist to understand the patient’s health condition. They show whether an infection or cavity has spread throughout the tooth. In addition, it shows how big the problem is. Using the software, dentists can compare images and use subtraction radiography to identify tinier changes. This helps them determine if the problem is too small to be detected on a regular examination.
Another type of x-ray is known as an orthopantomogram. This image shows all of the teeth on the lower face, including the gums and jawbone. In contrast to a regular x-ray, an orthopantomogram can detect other problems in the jawbone and Temporomandibular joint. If a problem is suspected, it can be treated using an orthopantomogram.
