  • Decay under fillings: Dental X-Rays are a boon here, as such types of decay can be detected only with the X-Ray. The x-ray of the decayed tooth will help you start the treatment in time and prevent further damage

Dental x-rays are no different than a normal x-ray and they are completely safe as you do one with your other organs in general. Infact, digital x-rays in dentistry expose a dental patient to a lower amount of radiation which is just a small fraction of the radiation compared to the normal imaging procedures carried out for other organs.

Therefore, if you ever think are dental x-rays safe then you are guaranteed now of its credibility and still if you have any doubts as why there is a need for x-ray, what exactly is the procedure and how its performed and in what situation they are to be performed or on children and all then let’s see that too so that you feel comfortable more about the dental x-rays as a safe procedure


There is very little concern or worry if the x-rays are performed with proper precautions and protection gear. Make sure the laboratory or the dentist is well equipped to perform one and a good hygiene maintained, and proper guidelines are followed while performing one.

Dental X-Rays and Children

Parents are extra cautious when it comes to children for anything and especially health related issues. On a good note, parents need not worry as X-Rays are safe for children and generally the cause of worry is due to the sensitivity exhibited by the children as they are more sensitive to the radiation passed through the teeth.


One of the main reasons X-rays are recommended for kids is they have a developing jaw and teeth with age. Hence, a vigil by parents is extremely helpful and important.

Some of the reasons why Dental X-Rays are performed on the children

  • The incoming teeth require a proper space in the mouth to erupt and develop too, so x-ray is performed to check on the space within the mouth.
  • To help see the development of wisdom teeth
  • Children are characterized by milk teeth or primary teeth at the initial stage and after which the permanent teeth develop so x-ray is needed to determine whether the primary teeth will fall off at the right time to give way to the permanent teeth.
  • Cavities and gum disease are a root cause of many dental problems and children are a favorite victim of it, so preventing these x-rays is good to be performed in regular intervals to nip the bud in time.

Dental X-Rays during Pregnancy

Women have to have additional care in everything when they are pregnant right from food to lifestyle and even medical treatments. X-Rays generally expose a human being to very minimum required radiation but over all dental x-rays during pregnancy are advised to be avoided or for the fact, any x-rays are advised not to be performed.


In the greater interest and care of developing fetuses it is better to avoid any type of x-ray. So, if you’re pregnant please make sure you inform your dentist about the condition.


Nevertheless, in some conditions dental x-rays during pregnancy are inevitable and they must be conducted like if a dental emergency lands with a pregnant woman or the treatment in the middle may require an x-ray to be performed.


If such a situation arises, inform and discuss with your dentist about the pregnancy and the dentist will provide you a best solution and a way forward about it. It’s important to be a responsible parent and take the charge of parenthood right from the time the fetus is in the womb and make the correct decision in the welfare of the child.


Women suffering with periodontal disease or gum disease must be careful as they are at a greater risk of unwanted consequences.


Make sure to have an open and transparent communication with your dentist with any fear if you’re pregnant as the dentist then will take extra precaution during the x-rays. The dentist will use a leaded apron and a thyroid collar in case of a pregnant woman for extra preventive care.

Safety measures during Dental X-Rays

Safety measures will help to reduce the amount of the radiation subjected to unnecessary areas of the mouth. The number of the x-rays taken also are important as with increase in number you’re exposed to more radiation, so a single proper image is best for the diagnosis, and in this case you have to be a responsible patient and do your homework in terms of expertise of the dentist.


In terms of children, request the dentist to set the radiation at the minimum which will satisfy the purpose of the x-ray also with it. One of the ways to guard your body from radiation are leaded coverings.
