If your dentist has recommended an IOPA dental X-ray, you probably have questions: What exactly is it? Does it hurt? Is the radiation dangerous? And what will it cost in Bangladesh? This guide answers those concerns in plain language. An IOPA (intraoral periapical radiograph) is a small, focused X-ray that shows the whole tooth — crown, root, and the bone around the root tip. It is one of the most common diagnostic tools in dentistry, used to spot problems that are invisible to the naked eye. The good news: the procedure is quick, painless, and exposes you to only a tiny amount of radiation — roughly the same you’d get from a day of normal background radiation. Below, we break down what to expect, how safe it is, and what it typically costs in Bangladesh.
What Is an IOPA Dental X-Ray?
An IOPA (intraoral periapical radiograph) is a type of dental X-ray that captures a detailed image of one or two specific teeth, including the entire root structure and the surrounding bone. The word periapical means “around the root tip” — exactly what this image shows. Unlike a panoramic X-ray (OPG), which gives a broad view of all your teeth and jaws at once, an IOPA zooms in on a small area, providing high-resolution detail that helps your dentist diagnose problems precisely.
The image is taken with a small sensor or film placed inside your mouth. Modern dental clinics in Bangladesh increasingly use digital sensors, which produce instant images on a computer screen and use even less radiation than traditional film.
Why Might Your Dentist Recommend an IOPA?
Your dentist will order an IOPA only when there is a specific clinical need — not as a routine for every visit. Common reasons include:
- Persistent tooth pain — to check for decay or infection deep inside the tooth.
- Suspected decay between teeth — cavities that are not visible during a visual exam.
- Root infection or abscess — to see the extent of infection at the root tip.
- Bone loss from gum disease — to assess the level of supporting bone around the tooth.
- Impacted wisdom teeth — to check their position and angle before extraction.
- Pre- and post-root canal treatment — to confirm the shape of the root canal and verify the filling after treatment.
- Trauma — to detect cracks, fractures, or damage to the root after an injury.
In every case, the decision is based on your symptoms and examination findings. Your dentist will explain why the X-ray is needed before taking it.
How Is an IOPA Taken? Step-by-Step
The entire process usually takes 5–10 minutes. Here is what you can expect:
- You sit in the dental chair. The dental assistant will place a lead apron over your chest and a thyroid collar around your neck to shield other parts of your body.
- A small sensor or film is placed inside your mouth. It may feel slightly odd, but it is not painful. You will be asked to bite down gently to hold it in place.
- The X-ray machine is positioned. The cone of the machine is aimed at the tooth from outside your cheek. The assistant will step behind a protective shield while the image is taken.
- The image is captured. You will hear a faint buzzing sound for a second or two. You need to stay still and hold your breath briefly to avoid blurring.
- The sensor is removed. If multiple teeth need imaging, the process may be repeated for each area.
- Results appear instantly. With digital systems, the image shows on a screen within seconds. Your dentist will review it and explain the findings immediately.
There is no recovery time — you can go back to your normal activities right away.
Is an IOPA Safe? Radiation and Pregnancy
This is the most common concern, and it is a fair one. The radiation dose from a single IOPA is extremely low — about 0.005 millisieverts (mSv). To put that in perspective, you are exposed to roughly 0.01 mSv per day from natural background radiation (sun, soil, air). So one IOPA is equivalent to about half a day of natural exposure. Digital X-rays use even less radiation than traditional film.
Dentists follow the ALARA principle — “As Low As Reasonably Achievable.” This means they only take X-rays when clinically necessary and use lead aprons and thyroid collars to minimize exposure to other parts of the body. For most patients, the diagnostic benefit of an IOPA far outweighs the tiny radiation risk.
Pregnancy: If you are pregnant or suspect you might be, always tell your dentist before any X-ray. In most cases, non-urgent X-rays can be postponed until after delivery. However, if you have a dental emergency (such as a severe infection), an IOPA with proper shielding is generally considered safe — the radiation dose to the abdomen is negligible. Your dentist will weigh the risks and benefits and make the best decision for you and your baby.
It is important to note that no medical procedure is absolutely zero-risk, but the risk here is very small and clinically justified. Do not refuse a needed X-ray out of fear — untreated dental infections can cause far more serious health problems.
How Much Does an IOPA Cost in Bangladesh?
The cost of an IOPA in Bangladesh varies depending on the city, the clinic’s reputation, and whether digital or film technology is used. Digital X-rays are slightly more expensive but offer faster results and lower radiation. Public hospitals and dental colleges often charge less than private clinics. The table below gives approximate ranges — always confirm the current price with the clinic before the procedure.
| Item | Approx. BDT Range | Notes |
|---|---|---|
| IOPA (digital) at a private clinic | ৳400 – ৳800 | Higher in Dhaka and Chattogram; includes instant on-screen results. |
| IOPA (film) at a private clinic | ৳300 – ৳500 | Lower cost but takes longer to develop; less common now. |
| IOPA at a dental college or public hospital | ৳150 – ৳300 | Subsidised rates; may require longer waiting times. |
Prices change over time and vary by location. Always call ahead to confirm the exact charge, and ask whether the fee includes the radiologist’s report and a copy of the image.
When to See a Dentist
Do not wait for a dental problem to become severe. See a dentist if you experience any of the following:
- Tooth pain that lasts more than a day or two
- Swelling, redness, or a pimple-like bump on your gums
- Pain when chewing or biting
- Sensitivity to hot or cold that lingers
- A broken, cracked, or loose tooth
- Bleeding gums or persistent bad breath
Early diagnosis with an IOPA can save your tooth and prevent more expensive and painful treatments later.

Frequently Asked Questions
How often can I safely have an IOPA X-ray?
There is no fixed universal limit — it depends entirely on your dental condition. For healthy adults having routine check-ups, most dentists only recommend X-rays when clinically needed, often every 1–2 years. If you are undergoing active treatment, such as a root canal or monitoring a persistent infection, more frequent IOPAs may be necessary. The radiation dose per image is very small, so occasional X-rays are considered safe, but always tell your dentist about your full medical and dental history so they can justify each exposure.
What is the difference between an IOPA and an OPG (panoramic X-ray)?
An IOPA focuses on one or two specific teeth, capturing the entire root and the surrounding bone in fine detail. An OPG, on the other hand, produces a single wide image of your whole mouth — all teeth, both jaws, and nearby structures like sinuses. IOPA is preferred when your dentist needs a close-up diagnosis of a particular tooth, such as a root infection, a crack, or decay between teeth. OPG is better for overall assessment, like checking wisdom tooth position or evaluating jaw problems. Your dentist will choose the right one based on what they need to see.
Do I need to prepare anything before an IOPA?
No special preparation is needed. You can eat, drink, and take your regular medications normally. Just remove any removable dental appliances, such as dentures or retainers, before the image is taken. It is also important to inform your dentist beforehand if you are pregnant, breastfeeding, or have any metal implants in your head or neck area. You will be given a lead apron to wear during the procedure, which adds an extra layer of protection.
Is an IOPA safe for children?
Yes, IOPA X-rays are considered safe for children when there is a clear clinical reason. The radiation dose is very low, and pediatric dentists follow strict safety protocols, including the use of lead aprons and thyroid collars specifically sized for children. An IOPA can help detect decay between teeth, track tooth development, or assess injuries early — which often prevents bigger dental problems later. If your child needs one, ask the dentist to explain why it is necessary and what they are looking for.
How long does it take to get the results, and who explains them?
In most clinics using digital radiography, the image appears on screen within minutes. Your dentist will usually examine it immediately and explain the findings in simple terms — whether they see decay, infection, bone loss, or a completely normal result. In some cases, the image may be sent to a radiologist or specialist for a second opinion, which can take a few hours to a day. Always ask your dentist to walk you through what the X-ray shows and what it means for your treatment plan.
Key takeaways
An IOPA dental X-ray is a safe, quick, and highly informative diagnostic tool. It helps your dentist see what is happening beneath the surface, leading to accurate diagnoses and better treatment outcomes. The radiation exposure is minimal — comparable to a day of natural background radiation — and modern digital systems make it even safer. In Bangladesh, the cost is affordable, typically between ৳300 and ৳800 at private clinics. If you have dental pain or other concerning symptoms, do not hesitate to see a dentist. An early IOPA can save you from more serious problems down the road.
