What is there to know about dental x-rays?

We are all familiar with the concept of x-rays. If you have ever dislocated your shoulder or perhaps your ankle, or if you were unfortunate enough to even break your leg or arm in the past, then you are very well acknowledged with the use of x-rays. The use of x-rays provides the chance for the doctor to determine where, how severe and of what kind is the injury that you have sustained. The dental x-rays serve a pretty similar task – to determine if there are any processes that are going on in the inside and outside of the teeth and gums and if so, how severe is the damage. Dental x-rays are the images that are used to help your dentist to determine and evaluate your oral health. Dental x-rays use a small amount of radiation to take pictures of your teeth and gums. Dental x-rays are just as important as cleansing your teeth if you want to have good oral health which is free of dental caries. Children, adults and older people are all supposed to get yearly dental x-rays, the only exception to this rule are pregnant women who are not supposed to undergo a procedure such as this one being exposed to even the slightest amount of radiation during their pregnancy. Other than pregnant women, the dental x-rays are a safe preventive and diagnostic method for people of all ages – from little children to adults.

Yearly dental x-rays and their role in the prevention of dental caries

While good oral hygiene, healthy diet and regular check-ups at the dentist’s office are the three major prevention [iii]steps for dental caries, recently, dentists all around the world have been talking about the importance of getting yearly dental x-rays in order to prevent dental caries for ever developing. Yearly dental x-rays have been found to pose as an effective [iv]prevention method for caries, enabling the dentist to see any present and hidden tooth decay – which is the process of destruction of the tooth enamel. By getting yearly dental x-rays done, your dentist will be able to detect any trace of tooth decay and any other hidden oral diseases which might come from the inside and show symptoms when there is a severe damage done to your teeth. If you are worried about the cost of getting yearly x-rays down – do not be, because, in most countries, dental x-rays are a part of your health insurance. Some patients worry about the radiation that they are exposed to when it comes to radiographic imaging. In the case of dental x-rays, the amount of radiation is quite small, so you do not have to worry about being exposed to radiation every year when you get your yearly dental x-rays done. As we mentioned before, only pregnant women are not supposed to sustain even the slightest radiation that comes from the use of dental x-rays. Yet, they can, of course, get their yearly dental x-rays done before and after their pregnancy which will account for yearly x-rays and achieve the same results and benefits. The dental x-rays are especially recommended [v]for children, due to their common exposure to dental caries. That is of course, because of their common intake of sweets and artificial sugars. An interval of one year is the perfect period of time between each dental x-rays in order to prevent dental caries among children.
