Understanding Dental X-rays

Why do dentists and other dental professionals use dental X-rays? Dental X-rays can supply a lot of information to the dentists though they may cause discomfort while being taken. They indicate where tooth decay and cavities are, they warn oral surgeons to the presence of nerves or misshapen teeth and roots, they reveal the location of wisdom teeth, bone loss, and presence of cysts, tumors and supernumerary (extra) and impacted teeth.Dental X-rays also point out fractures or cracks and can be a means of recognizing a person at sometime in the future.

X-rays are used regularly by most dental professionals, and so such machinery can be found in about every dental establishment. The method of producing an X-ray generally requires the patient to wear a leaden vest first; the technical person or the dentist then places a little cardboard or plastic container inside the patient’s mouth, adjusts it into proper position, and requests them to hold it in its position by biting hard on it. This is frequently a very uncomfortable moment, but lasts for only a few seconds. The X-ray plates are next developed and mounted for the dentist to have a look.

Why does the patient need a lead vest? Since patients are exposed to radiation during the procedure, there should be some sort of a protection to shield them from it. Most dental offices offer the latest lead vests that have collars to cover the throat and shield the thyroid gland from radiation.Realistically, the amount of radiation from a dental X-ray is inconsiderable and nothing to be concerned about. Most states have laid down strict laws over X-ray equipment, making it mandatory to use the least amount of X-rays possible to get good images.

Is there a suggested schedule for people to have dental X-rays taken? There are federal guidelines regarding the permitted frequency of dental X-rays for those at high or low risk of dental decay. For those at little risk for decay the Federal Drug Administration suggests X-rays every two to three years (for adults), and for those at risk they suggest every year or every eighteen months.Most dentists will take X-rays of their patients as part of a regular check-up.

Modern digital radiography has rendered the old method of using plastic or cardboard film plates totally obsolete.

Interestingly, the developing trends in body piercing, including those of the lip, tongue, cheek and nose may interfere with the results of an X-ray. Additionally, people with braces or retainers, dentures and bridges may also not be able to have certain X-rays taken.

There are quite a few types of dental X-rays that are used for different medical investigations. Each of them focuses on a separate area of the mouth as well as the palate, sinuses and the nasal passages.This is done to comprehensively assess different areas of the mouth that are vulnerable to dental ailments.
