Dental X-rays enable your dental professional to obtain a more comprehensive view of your oral health. They can detect invisible bone loss, cavities, and even infections. Dental X-rays also help track healing and plan treatments such as braces or implants.
Many people usually need to know how frequently they should have dental X-rays, and understandably so. Knowing why and when you should undergo dental X-rays will empower you and help you make informed decisions regarding your oral care while maintaining maximum dental health monitoring. The answer to this question depends on a person's dental and medical history and the state of their mouth. This blog answers this question more comprehensively.
The Frequency of Dental X-rays Partly Depends on the Types
Regardless of how good their eyes are, dental professionals cannot view inside or between your teeth. Neither can they see your tooth roots or the jawbone surrounding them, and that is where dental X-rays become helpful. There are three types of dental X-rays. These are bitewing, periapical, and panoramic X-rays.
- Bitewing dental X-rays. These are typically taken during regular dental appointments. They can reveal cavities that have begun to form between teeth and jawbone loss because of gum disease. These X-rays capture images of your lower and upper rear teeth in a single film, making them the best for monitoring jawbone levels and detecting decay between teeth. The images provide invaluable details about spots your dental professional cannot view during a visual exam.
- Periapical dental X-rays. These are taken to diagnose a cyst, dental abscess, or tooth root problems, as well as to show any abnormalities in the surrounding bone. They show the entire tooth from the crown to the tip of the root.
- Panoramic dental X-rays. If you need your wisdom teeth extracted, your dental professional may conduct a panoramic dental X-ray. The X-rays capture the whole mouth, including the jaws, teeth, and adjacent structures in a single image. These detailed images enable the dental professional to identify the precise location of tumors, jaw problems, impacted teeth, temporomandibular joint (TMJ) issues, and other conditions needing specialized treatment.
A full-mouth series of dental X-rays combines multiple bitewing and periapical X-rays to provide comprehensive documentation of a patient's dental health status. They are generally performed on new patients or people with intricate treatment needs.
How Often Should You Have Dental X-Rays?
Regular dental appointments often include X-ray imaging to help dentists accurately evaluate patients’ health. Even though they are an invaluable diagnostic option with lower radiation exposure, there is no need for the dentist to conduct more X-rays than are actually necessary. So this dilemma begs the question: how frequently should dental X-rays be taken for any given patient, and when should they be taken?
It varies from one patient to another and depends on various factors. Some patients may require dental X-ray imaging as frequently as twice a year. People who schedule regular dental visits and maintain good oral health might have X-rays conducted only every three or so years. The United States Food and Drug Administration (FDA) and the American Dental Association provide the following guidelines on how often different individuals may need dental X-rays:
- New patients. If it is your first time seeing a dentist, the dentist will generally recommend a detailed baseline exam, including a complete set of dental X-rays to detect any existing issues. These initial X-rays provide a full view of your dental health and serve as a baseline for the visits that will follow. Patients who maintain good oral health and have a lower risk of developing dental diseases may require X-rays every 18-24 months. Those with active cavities, complicated treatment needs, or periodontitis require frequent monitoring.
- Adults. For adult health maintenance, a healthy patient generally needs bitewing dental X-rays every 12 to 18 months, but they can go longer between X-rays. Dental professionals recommend a complete mouth series every 3 to 5 years. However, your dental professional may adjust this schedule contingent on your current condition and dental health history.
- Children. This group of patients requires special consideration when discussing dental X-rays. Most dental professionals start taking dental X-rays when a child's baby teeth begin to touch, typically around ages 4 and 6. During decay-prone years and rapid development in children, imaging more often helps monitor how teeth emerge and identify possible problems on time. Panoramic imaging is especially essential during orthodontic care planning stages.
To lower the radiation level to which a person is exposed with dental X-rays, the ADA has various recommendations. Experts say that you should undergo dental X-rays only when your dental professional believes they will generate the requisite diagnostic information that will help you achieve your best oral health.
Dental professionals should always conduct a clinical examination and assess a patient's medical and oral history before performing a dental X-ray. If you are prone to periodontal problems or have extensive decay, your dental professional may recommend frequent dental X-rays. Due to their developing jaws and teeth, minors may require X-ray exams more often than adult patients.
The ADA’s suggestion for a rear bitewing examination for a patient currently suffering from tooth decay and who has a heightened risk for dental cavities is 6- to 18-month intervals. On the other hand, a person with no tooth decay or a lower risk can go 2 to 3 years between dental X-ray imaging.
The logic behind lengthier intervals is that dental decay progresses gradually through the enamel. Thus, even with more extended periods between X-rays, any cavity would be identified before it spreads to the dentin.
What Is the Risk?
Every time you undergo a dental X-ray, you are exposed to a given degree of radiation. Radiation has constantly been associated with some types of cancer, particularly in children. So, you do not need to be more exposed than necessary. However, with modern technology, X-rays emit very low levels of radiation. Actually, the radiation amount from a series of dental-related X-rays equals the radiation amount you absorb from your computer, smartphone, or television.
Dental X-rays have lower radiation exposure. However, radiation builds up in a person's body from numerous sources as time passes and never disperses. The American Dental Association recommends that dental professionals should expose individuals to as low a radiation amount as reasonably possible every time they do so.
Surprisingly, the American Dental Association’s current recommendations are that dental professionals should no longer utilize lead aprons to cover patients’ bodies during dental X-rays. The suggestion applies to every patient, irrespective of their age, oral health status, or pregnancy status. According to available evidence, today's digital dental X-ray tools and other measures safeguard patients against excessive radiation exposure more effectively than ever before.
Key Factors Determining Dental X-ray Frequency
The frequency with which to undergo X-rays is unique to the specific patient. Your dental professional weighs several important factors to determine when X-rays will deliver the greatest advantage while keeping your exposure to radiation lower. Knowing these factors will help you make informed decisions regarding your dental care.
General History of Oral Health
Your dental health history is an essential determinant of your needs. Your prior experiences with fillings, gum disease, or cavities are direct signs of whether you are or will be at risk in the future. If you develop cavities more frequently, new ones are highly likely to form after treatment. That justifies having more X-rays more frequently to detect them early, before they cause a bigger issue. Discuss your oral health record with your dental professional to determine whether you are a high-risk patient.
That is why if you start seeing a new dental professional, they will virtually always suggest a complete set of dental imaging in your initial appointment. It is not only about seeing what is there now, but also about establishing a comprehensive reference point to track even the slightest changes over a certain period and customize a personal dental care schedule. This decision-making process gives you an excellent sense of how dental professionals think through it.
Your individual risk level, whether high, low, or dependent on your stage in life, primarily influences the recommended frequency of dental X-rays.
Age and Stage In Life
Age contributes significantly to how often a person should undergo dental X-rays. The mouth of a child is constantly changing—deciduous teeth fall off, permanent teeth grow in, and the jawbone develops. This ever-changing environment requires closer monitoring. That often means dental X-rays every 6 months to 1 year to detect developmental problems early enough.
For an adult with good oral health and no significant dental issues, there is a low likelihood of unexpected changes in the mouth. In this case, a dental X-ray every 2 to 3 years may be adequate to track slow-developing issues.
Risk Factors and Current Symptoms
What is currently happening in your oral cavity can overrule any regular schedule. Should you visit your dentist with tooth sensitivity, swelling, or a toothache, they will recommend taking a dental X-ray immediately, irrespective of how much time has passed since you last took one. These symptoms could be signs of hidden problems such as an abscess, cracked root, or deep decay.
Apart from unexpected symptoms, specific ongoing conditions may also lead your dentist to classify you as a higher-risk patient, warranting more frequent dental X-rays. Ensure you inform your dental professional should you experience the following conditions:
- Xerostomia (dry mouth). Saliva helps keep the teeth and mouth healthy by regulating the pH (acid levels) in the oral cavity. If you have xerostomia, the pH of your saliva decreases. This leads to the minerals in teeth disintegrating, which dramatically increases the risk of more aggressive tooth cavities. This phenomenon makes routine monitoring critical. Many medications can cause xerostomia. This condition can also arise due to a long-term disease or cancer treatment.
- Gum disease. X-rays are crucial for measuring jawbone loss around teeth, an essential step in managing the disease. If you have lost so much bone, you might require periodontal surgery.
- Extensive dental work. An oral cavity with many large fillings, bridges, implants, and crowns needs dental X-rays more often to ensure these restorations stay healthy and to detect decay or other issues starting beneath existing restorations before they become symptomatic.
- Smoking and tobacco use. Smoking heightens the risk of jawbone loss around teeth and gum disease. On the other hand, chewing tobacco is often sweetened with sugars and can result in more dental cavities. You may need to undergo dental X-rays more often to monitor the condition of your mouth.
When your dentist carefully considers all of the above factors, they can confidently tell you how frequently you should have X-rays. It is a thoughtful, evidence-based process meant to retain the health of your distinctive smile for a lifetime.
Keeping Dental X-Rays to a Minimum
The following are some of the ways to save yourself from radiation exposure and the cost of unnecessary X-rays:
- When changing dental professionals, take the most recent X-ray you did with you
- Maintaining good dental health by sticking to a diligent habit of flossing, brushing, and seeing a dental professional regularly for check-ups.
- Discuss concerns regarding dental X-ray frequency with your dental professional. They may have recommendations to help you last longer between X-rays without jeopardizing your dental health.
That said, dental X-ray procedures are necessary. That is because without them, minor undetected issues can worsen and become more challenging to address. However, you do not want to undergo X-rays without a valid clinical reason.
