Are Dental X-Rays Necessary? 7 Compelling Reasons We Say Yes

Getting dental X-rays during routine dental visits offers numerous benefits. These X-rays give our dentists a detailed view of the health of your teeth, bones, and gums, allowing for the early detection of potential issues. The process is both quick and painless. But are dental X-rays necessary?

While we believe X-rays are an excellent tool for maintaining healthy teeth, we only recommend them when necessary. Let’s explore some additional reasons why dental X-rays are essential for preserving your smile for years to come.

Why do I need a dental X-ray?

Often people don’t understand the need for a dental X-ray. After all, their teeth look fine, so why have an X-ray?

A dental X-ray is a bit like looking into the future with a crystal ball. It helps us identify problem areas and conditions that can’t be seen with a routine examination. It also aids the early detection of oral health problems such as gum disease and cavities, before they have a chance to worsen.

So what can dentists discover when they look at an X-ray?

One of the first things an X-ray reveals is whether or not a patient has any teeth that are hidden beneath the gums. Some teeth, like wisdom teeth, may not be causing any issues now but have the potential to become problematic further down the line.

Dental X-rays also reveal the level and density of the bone structure supporting the teeth. While this enables a dentist to determine whether you require any special gum treatments, it also shows if the bone is sufficiently healthy to support dental implants.

Finally, X-rays reveal any underlying issues with the teeth, enabling us to identify and treat any issues you may have.

What sort of issues are we referring to?

Factors like:

• Tooth decay – Dark spots on X-ray images typically mean the presence of decay. A dental X-ray makes it easier for dentists to spot hidden decay between teeth and tiny cavities that escaped detection.
• Periodontal disease – An infection around the root of a tooth isn’t always visible but a dental X-ray can tell a dentist exactly what is going on.
• Infection – X-rays act like dental detectives, uncovering details that even the most well-trained eye might miss. Infections appear as shadows or dark spots signalling trouble in the form of an abscess or infection in the root canal system.
• Tumours and cysts – While it’s relatively rare, patients can develop tumours and cysts in the jaw bone. A panoramic X-ray helps check the entire jawbone for any abnormalities or growths.

The fact that all of these issues can be detected and treated before they become bigger, more expensive problems, is why we answer the question “Are dental X-rays necessary?” with an emphatic, yes!

Types of dental X-rays

Dental X-rays can be divided into two main categories:

Intraoral X-rays – are the most common type of dental X-rays, providing detailed images of the teeth, bone, and surrounding tissues inside the mouth. These X-rays help in detecting cavities, monitoring tooth development, and assessing the health of the tooth roots and jawbone.

Extraoral X-rays – focus on the larger structures of the head and jaw, capturing images from outside the mouth. They are less detailed compared to intraoral X-rays but are useful for examining the jaw and skull, diagnosing TMJ disorders, and planning orthodontic treatments.

How often should patients have dental X-rays?

There is no straightforward answer to this question because the frequency depends on several factors including age, oral health history and current condition of your oral health. Generally, most people will have a dental X-ray every one to two years to help our dentists detect any changes or problems in their mouth or teeth.

What are the risks?

A dental X-ray is estimated to expose a patient to 0.005 mSv (millisievert) of radiation. So the risk is minimal. To better understand this, it’s helpful to compare it with the radiation exposure you might regularly encounter from other sources. For instance, building materials often contain natural radioactivity, which can expose occupants to low levels of radiation, as can various types of food and other medical procedures.

How much radiation is too much?

According to Public Health England, on average, people in the UK are exposed to around 2.7 millisieverts of radiation a year. Exposure to a higher dosage than this could endanger a person’s health in later years.

So, now you have a better understanding of the role dental X-rays play in dentistry, let’s look more closely at the reasons we believe dental X-rays are necessary.

7 reasons we recommend dental X-rays

1. By identifying issues early that might not be apparent during a standard dental check-up, we can address them before they escalate into more serious concerns.

2. To assist in planning for urgent treatments, upcoming procedures, or achieving a complete smile makeover!

3. To track the changes in your teeth and gums over time, providing valuable insight for early problem detection and ensuring your at-home dental care is effective.

4. To review the outcomes of your treatment and confirm that they meet expectations. Our dentists can make necessary adjustments during the process, guided by your X-ray results.

5. To identify complications with dental implants, including potential infections or harm to neighbouring teeth.

6. To evaluate your risk of tooth decay and offer personalised advice to minimise the chance of cavities based on the assessment.

7. To detect gum disease and assess the overall health of your mouth.
