Radiographs as a Diagnostic Tool in Dentistry

January 8, 2018

Although some people dislike the idea of ‘x-rays’ at the dentist, radiographs are one of the key diagnostic tools for determining someone’s overall oral health. This month’s blog will investigate the different types of radiographs that are taken, why they take them, and the importance of them for diagnosing oral disease.


Generally, when patients first come to an office, a comprehensive set of radiographs is taken. Depending on the patient’s age and oral condition, that could consist of a Full Mouth Series (FMX) or Panoramic radiographs. A FMX series consists of about 18 radiographs that examines each tooth at different angles to search for the present of decay or periodontal disease. Panoramic radiographs give a more widespread view of the mouth, but sometimes do not give as detailed of a picture of individual tooth problems. When patients are younger, generally a Panoramic radiograph can provide good imaging of erupting teeth and whether any are missing or impacted.


Once these full sets are taken, they do not need to be retaken for about 5-7 years unless a patient has a new problem. Usually, they just have Bitewing radiographs updated every 12-24 months depending on the rate of tooth decay they get. Bitewings are a set of four radiographs that go straight through the teeth and are usually most useful when trying to diagnose cavities. Dentists can see the exterior enamel layer, inner dentin, and the pulp (nerve/blood vessel) of the teeth. Also usually the supporting bone level and existing fillings/crowns/implants can be viewed.


Many patients have a sense of trepidation about taking dental radiographs. They are usually worried about the amount of radiation they may absorb. While this is a valid concern, sometimes people do not understand the exact amount of radiation they are experienced to every day. The below chart takes different dental radiographs and compares them to the amount of background radiation people receive from everyday life. ‘Background radiation’ comes from many sources – from food/water, occupational exposure, and even substances that are commonly found in homes. From the comparison – the amount of radiation from even a FMX or panoramic radiograph is equivalent of only several days of regular background radiation.


If there is ever any concern about the radiographs being taken at the office, please feel free to speak to your dentist or hygienist about the reasoning behind them. Obviously excess exposure is never a good thing, but they can also be keys to diagnosing oral problems early on before they can worsen. Hopefully this served as an informative source for the types of dental radiographs and why they are necessary.

Pregnancy is a time of excitement, anticipation, and transformation. As your body adapts to nurture new life, your needs evolve—including your dental care. At Stephens Dentistry, we’re passionate about supporting expectant mothers through every stage of this journey. Understanding the connection between oral health and pregnancy is not just important for your smile, but for the wellbeing of both you and your baby.  How Pregnancy Impacts Oral Health Pregnancy brings about a surge in hormones, especially estrogen and progesterone, which can have a profound effect on your gums and teeth. Many women notice changes in their oral health during pregnancy, including increased sensitivity, swelling, or bleeding gums. These shifts aren't just uncomfortable—they can also signal conditions that need attention to safeguard your overall health. Pregnancy Gingivitis: What You Need to Know One of the most common dental issues during pregnancy is pregnancy gingivitis. According to the Centers for Disease Control and Prevention , up to 60–75% of pregnant women develop gingivitis, which is characterized by red, swollen, and bleeding gums. This occurs because hormonal changes heighten the body’s response to the bacteria in dental plaque. If left untreated, gingivitis can progress to periodontitis—a more serious gum infection that can cause tooth loss and has been linked to health risks beyond the mouth. Oral Health and Birth Outcomes The importance of oral health during pregnancy goes beyond comfort and aesthetics. Research has shown a significant link between maternal gum disease and adverse pregnancy outcomes, such as preterm birth and low birth weight. A systematic review published in the Journal of Dental Research found that women with periodontal disease may be more likely to deliver prematurely or have babies with low birth weights. Although more research is ongoing, the potential connection means that taking care of your gums and teeth is an essential part of prenatal health. Why Dental Care Shouldn’t Wait Some expectant mothers worry about dental treatments during pregnancy. The good news is that routine dental care—including cleanings and necessary treatments—are not only safe but recommended during pregnancy. The American College of Obstetricians and Gynecologists confirms that preventive dental work is important and can be performed safely, especially in the second trimester. Delaying care can allow small problems to become bigger ones, and untreated infections can pose a risk to both you and your baby. If you are planning to become pregnant, scheduling a dental checkup beforehand is an excellent way to get ahead of any issues. Practical Tips for Expectant Mothers Maintaining oral health during pregnancy doesn’t have to be complicated. Here are some tips to keep your smile healthy throughout your pregnancy: Brush and Floss Regularly: Aim to brush twice a day with fluoride toothpaste and floss daily. This helps remove plaque and reduce your risk of gingivitis. Eat a Balanced Diet: Focus on nutritious foods rich in calcium, vitamin D, and protein, which support both your oral and overall health. Manage Morning Sickness: If you experience vomiting, rinse your mouth with water or a fluoride mouthwash rather than brushing immediately afterward, as stomach acid can soften tooth enamel. Stay Hydrated: Drinking plenty of water helps wash away food particles and bacteria, and can also help combat dry mouth, which is common in pregnancy. Schedule Regular Dental Visits: Let your dental team know you are pregnant so they can tailor your care. At Stephens Dentistry, we take extra precautions to ensure your comfort and safety during each visit. Learn more about our preventive dental services . Recognizing When to Call Your Dentist While mild gum sensitivity is common, it’s important to reach out to your dentist if you notice persistent bleeding, swelling, or pain. These symptoms could indicate an infection that needs prompt attention. If you develop a dental emergency during pregnancy, don’t hesitate to contact your dentist—timely care is always the best choice for both you and your baby.
