If you’re considering wisdom teeth extraction, you may wonder if dental X-rays are necessary. The answer is yes! X-rays are an important part of the process when it comes to removing wisdom teeth. Wisdom teeth, also called third molars, are the last adult teeth to emerge in the back of the mouth.
They often don’t have enough space to grow properly and can cause pain, infections, and even damage to neighbouring teeth. A dental X-ray is necessary to assess the teeth’ position and plan for extraction. This article will explain why a dental X-ray is important for wisdom teeth extraction and what you can expect during the procedure.

Understanding Wisdom Teeth Extraction
Wisdom teeth develop between the ages of 17 and 25 and can cause problems due to their position or size. Signs that may indicate the need for wisdom teeth extraction include severe pain, infections, and damage to adjacent teeth. If left untreated, wisdom teeth can cause complications such as bone loss and nerve damage.
Practising good dental hygiene, including regular brushing and flossing, is important before the extraction procedure. Dental X-rays, including panoramic X-rays and OPG X-rays, are commonly used to plan for tooth extraction and determine the position of the teeth and surrounding structures. After a consultation with a dentist, crooked wisdom teeth can be removed using surgical procedures under local anesthesia or general anesthesia.
Pain relief medication may be necessary to manage pain following the procedure. It’s crucial to follow the dentist’s instructions for post-operative care closely and to monitor for signs of infection, including swelling and fever, in the days following the surgery.
What is a Dental X-Ray?
Dental X-rays are an essential diagnostic tool for the wisdom teeth extraction process. X-rays provide detailed imaging of the teeth and surrounding soft tissues, allowing the dentist to assess the position of the wisdom teeth and plan for the extraction procedure. Digital X-rays produce images in digital files, which can be accessed for diagnosis at any time and from anywhere without any constraints of time and place.
Without a dental X-ray, it’s difficult for the dentist to fully understand the position of the teeth, which can lead to complications during the extraction procedure. Among other applications, dentists can utilise it to plan dental implants, assess jaw bone issues, plan a root canal, or monitor the condition of a wisdom tooth.
Dental X-rays come in two main types: Intraoral and extraoral. Intraoral X-rays use a film or sensor inside the mouth, while extraoral X-rays use a film or sensor outside the mouth. Types of Intraoral X-rays include:
- Bitewing X-rays:
Shows the upper and lower teeth in a specific mouth area and detect decay between teeth and changes below the gum line. It doesn’t usually show the roots of the teeth.
- Periapical X-rays:
Show the entire tooth from the crown to the root tip and helps to detect tooth decay, gum disease or periodontal disease, bone loss, and other abnormalities in the tooth or surrounding bone.
- Occlusal X-rays: Detects issues in the roof or floor of the mouth, helps to diagnose fractured or impacted teeth and evaluates the roots of the front teeth. It also identifies cysts, abscesses, and jaw fractures.
Extraoral X-rays come in several types:
- Panoramic Dental X-rays:
Shows all oral structures in a single image, including upper and lower teeth, jaw joints, nerves, sinuses, and supporting bone. It gives an overview of existing oral health issues.
- Cephalometric X-rays:
Show the entire head from the side and the location of teeth to the jaw. Orthodontists use it to plan treatments.
- Cone beam CT scan:
Captures 3D dental X-rays of teeth, jaws, joints, nerves, and sinuses, detecting tumours or facial fractures. Surgeons use it to check the jawbone’s height, width, and location before implant placement.
After being directed towards the area of interest, the X-ray machine promptly administers an X-ray beam with minimal radiation to the region, generating an image on a specialised detector or X-ray film. Dental X-ray images show a two-dimensional view of the teeth and surrounding tissues.
These images assess the wisdom teeth’ position and any underlying dental problems that may affect the surgery. Each type of X-ray has advantages and limitations, and the dentist will choose the type best suited to the patient’s needs.
When interpreting dental X-ray images, the dentist will look for the following:
- The position of the wisdom teeth includes whether they are impacted or have grown at an angle.
- The proximity of the wisdom teeth to other structures in the mouth includes nearby nerves, sinuses, and adjacent teeth.
- Any underlying dental problems, including cavities, gum disease, cysts, or tumours, must be addressed before the surgery.
By carefully analysing the dental X-ray images, the dentist can determine the best course of action for extracting wisdom teeth safely and with minimal risk of complications. If wisdom teeth are not extracted when causing problems, they can lead to several complications. These complications can include the following:
Wisdom teeth can cause severe pain, particularly if impacted or infected.
Wisdom teeth that are partially erupted can be difficult to clean properly, leading to infections.
- Damage to adjacent teeth:
Wisdom teeth growing in at an angle can push against neighbouring teeth, causing damage or misalignment.
- Bone loss:
Wisdom teeth that are partially erupted can create a pocket of bacteria around the tooth, leading to bone loss in the jaw.
- Nerve damage:
In rare cases, extracting wisdom teeth can lead to nerve damage, which can cause numbness or tingling in the mouth and face.
Importance of Dental X-rays for Wisdom Teeth Extraction
Here are a few reasons why a dental X-ray is necessary before wisdom teeth extraction:
- To determine the position of the teeth:
A dental radiography can reveal the position of the wisdom teeth, including whether they are impacted or have grown at an angle. This information is critical for planning the extraction procedure.
- To assess the risk of complications:
A dental X-ray can also reveal the proximity of the wisdom teeth to other structures in the mouth, such as nerves or sinuses. This information is essential for determining the risk of complications during the extraction procedure.
- To identify any underlying dental problems:
A dental X-ray can reveal any underlying dental problems, such as cavities or gum disease, that may need to be addressed before the extraction procedure.
While a physical examination can provide some information about the position of the teeth, it has its limitations. Here are a few limitations of a physical examination without a dental X-ray:
- Only surface-level information is available:
Without an X-ray, a dentist can only see the parts of the teeth visible in the mouth. This means that they may miss important information about the position of the teeth beneath the gum line.
- Difficult to identify impaction:
Impacted wisdom teeth are trapped beneath the gum line. Without an X-ray, it’s difficult to determine whether a wisdom tooth is impacted.
The risks of not having a dental X-ray before wisdom teeth extraction include the following:
- Damage to neighbouring teeth:
Without an X-ray, it’s difficult to identify the position of the wisdom teeth with neighbouring teeth. This can increase the risk of damage to nearby teeth during the extraction procedure.
- Incomplete extraction:
Without an X-ray, it’s possible that the dentist may not be able to remove the wisdom tooth entirely or may leave behind small fragments. This can lead to pain, infection, and other complications.
The Dental X-Ray Procedure: What to Expect
If your dentist has recommended a dental radiograph for your wisdom teeth extraction procedure, you may wonder what to expect. Here is an overview of the steps involved in the dental X-ray procedure:
Preparation for the procedure:
- The first step in preparing for a dental X-ray is to inform your dentist about any medical conditions or allergies you may have.
- Before the procedure, you may be asked to remove any jewellery or metal objects from your mouth or places near your mouth, such as your nose or ear rings.
- Your dentist may also ask you to wear a lead apron to protect the rest of your body from radiation.
Steps of the procedure:
- During the procedure, you will be asked to sit or stand in front of an X-ray machine.
- Your dentist or dental assistant will place a small sensor or film inside your mouth to capture the X-ray images.
- You will be asked to hold still while the X-ray machine is turned on.
- Your dentist may take several X-rays from different angles to get a complete picture of your teeth and jaw.
Duration of the procedure:
- The dental X-ray procedure usually takes only a few minutes to complete.
- You may need to wait a few minutes while the images are developed or processed.
Safety precautions during the procedure:
- Dental X-rays are generally safe, but there are some precautions that your dentist will take to minimise your radiation exposure.
- You will be asked to wear a lead apron to protect your body from radiation.
- Your dentist will also use the lowest possible radiation dose to capture the images needed for your procedure.
Interpreting the Dental X-Ray
Once the dental X-ray images have been captured, they must be interpreted to plan for a wisdom tooth removal. Here are a few things to know about interpreting dental X-rays:
- Who interprets the dental X-ray? A dentist will interpret the dental X-ray images. They will look for abnormalities or problems affecting the wisdom teeth extraction procedure.
- Understanding the images. Dental X-ray images may be captured using film or digital X-rays. They show a two-dimensional view of the teeth and surrounding tissues. Your dentist will use the images to assess the wisdom teeth’ position and any underlying dental problems.
- Abnormalities that can be seen on the dental X-ray. Dental X-rays may reveal abnormalities such as impacted wisdom teeth, cavities, gum disease, and cysts or tumours. Your dentist will use this information to determine your best course of action and sometimes advise root canal therapy if needed.
- The potential impact of the dental X-ray results on wisdom teeth extraction. The results of the dental X-ray will have a significant impact on how your wisdom teeth are extracted.
Suppose the X-ray reveals that the wisdom teeth are impacted or in a difficult position. Your dentist may need special tools or techniques to remove them safely. If the X-ray reveals underlying dental problems, your dentist may need to address these issues before proceeding with the extraction.
In conclusion, standard dental X-rays are essential for wisdom teeth extraction. They provide critical information about the position of the teeth, the risk of complications, and any underlying dental problems that may need to be addressed before the extraction procedure. The dental X-ray procedure is safe, non-invasive, and typically only takes a few minutes to complete. Interpreting the images requires the expertise of a dentist who will use the information to plan the best course of action for your wisdom teeth extraction.
