A frequently asked question at our office is, ?How often should I have x-rays taken??This is a great question! As a general rule of thumb, you should get a set of bitewings taken once a year, and a full mouth series (FMX) once every 3 years. Of course, if you are experiencing pain (other problems/concerns/suspicion) in between x-rays, additional ones may need to be taken to diagnose what is going on.? In this post we?ll explore the risk of radiation from dental x-rays and the factors that determine how often you need x-rays taken.
HOW MUCH RADIATION IS IN A DENTAL X-RAY?
Modern, digital x -rays are extremely low in radiation, unlike older x-ray machines. ?In fact, the dental assistant in our office stays in the same room with the patient while the x ?rays are taken.
FACTORS THAT DETERMINE HOW OFTEN YOU SHOULD HAVE DENTAL X-RAYS TAKEN:
EXISTING RESTORATIONS AND PREVIOUS DECAY
The number one factor for determining how often you need dental x-rays taken is the amount of fillings or restorations you already have in your mouth. If you have multiple fillings or other dental restorations, you need to have x-rays taken more often. It is important not only to monitor the state of the fillings and restorations you have, but also to keep an eye on the surrounding teeth because you are more prone to decay.
AGE:
Certain ages are more prone to specific complications, and therefore need to have x-rays taken more frequently to check for decay or other possible complications. An example of this would be around age 17 when the wisdom teeth usually come in.? The 3rd molars need to be looked at through radiographs to see if they are causing problems and need to be removed. ?Also, children?s teeth are more susceptible to cavities and need to be radiographed more often.
OVERALL ORAL HEALTH
Plain and simple: Some people are more prone to cavities and/or gum disease. People that have shown that they are at a higher risk of getting cavities or gum disease need to have dental x-rays taken more often, to catch signs of these at the earliest stages possible. On the contrary, patients that have shown that they are not cavity-prone can go longer in between x-rays.
PREVIOUS OPERATIONS AND PROCEDURES
Patients that have had serious oral surgeries or restorations need to keep a closer eye on what is going on with their oral health than others. X-rays not only detect decay but also can detect other complications like bone degeneration, or an infection at the root of a tooth.? Patients with dental implants need to have x-rays taken regularly to monitor any irregularities or changes.
MEDICATIONS
Some medications can cause dry mouth, and make you more susceptible to decay. Other medications can cause other complications to oral health, such as weaker bone. People taking medications that affect the oral cavity need to have x-rays taken more often.
LOCATION
Unfortunately (or maybe, fortunately), where you grew up may influence how often you need to have x-rays taken. Some cities have higher amounts of fluoride in the water source, which has shown to promote oral health in those areas. If you grew up somewhere that fluoride wasn?t a part of the drinking source, you should get x-rays more often to keep an eye on decay.
CANCER TREATMENT
Having undergone cancer treatments is an important factor in determining how often you should have dental x-rays taken. Some cancer treatments such as chemo and radiation therapy can have negative effects on teeth and surrounding bone and should be monitored. Always let your dentist know what type of cancer treatments you have undergone so that they can plan your x-ray treatment accordingly and safely.
WHY DO I NEED DENTAL X-RAYS?
Dental x-rays are one of the most important parts of maintaining good oral health because they give the dentist a picture of what is going on beneath the surface of the teeth. Having x-rays taken regularly can diagnose and prevent serious complications that would otherwise go unnoticed.
