When Is an OPG Scan Needed and How to Prevent Those Conditions?

Maintaining oral health goes far beyond brushing and flossing. Sometimes, dental issues lurk beneath the surface inside the jaw, under the gums, or around the roots of teeth, making them difficult to detect through a routine check-up alone. This is where the OPG scan plays a crucial role. "OPG” stands for Orthopantomogram. It is an imaging diagnostic procedure performed in dentistry but one might wonder under which condition an OPG scan in Delhi is needed and, most importantly, how to prevent these conditions. In this blog we will explore what an OPG scan is, common conditions that require an OPG scan and preventive steps to avoid these oral health issues. 

Understanding an OPG Scan?

An OPG (Orthopantomogram) is a panoramic dental X-ray that captures the entire mouth in a single image, including the upper and lower jaws, teeth, temporomandibular joints (TMJ), and sinus areas. It provides a broad overview of dental structures, which helps dentists diagnose and plan treatment efficiently.

It is:

• Quick and painless
• Non-invasive
• Involves minimal radiation exposure

Conditions That May Require an OPG Scan

Here are the conditions that may require an OPG scan that are mentioned below: 

• Impacted Wisdom Teeth:

Wisdom teeth often grow at awkward angles or fail to erupt completely, causing pain or damaging nearby teeth. An OPG scan helps determine their exact position and the extent of impaction.

Prevention Tip:

While impaction may not always be preventable due to jaw size or genetics, regular dental check-ups during teenage years can catch issues early and allow for timely intervention.

• Dental Infections and Abscesses

Infections beneath the gums or at the root of a tooth are not always visible. An OPG reveals the presence of deep abscesses, cysts, or infection in surrounding bone structures.

Prevention Tips:

1. Practice good oral hygiene (brush twice a day, floss daily).
2. Avoid sugary snacks and drinks.
3. Treat cavities and gum disease early to prevent them from progressing to infections.

• Temporomandibular Joint (TMJ) Disorders

TMJ disorders cause pain or dysfunction in the jaw joint. An OPG scan helps assess joint structure and alignment.

Prevention Tips:

1. Avoid excessive jaw movements (e.g., chewing gum, teeth grinding)
2. Manage stress (bruxism is often stress-related)
3. Seek early treatment for jaw pain or clicking

• Jaw Fractures or Bone Abnormalities

After facial trauma or injury, an OPG can quickly assess for jaw fractures or bone loss due to diseases like osteoporosis or tumors.

Prevention Tips:

1. Wear protective gear during contact sports
2. Maintain bone health with adequate calcium and vitamin D
3. Avoid habits that weaken bones, like smoking or excessive alcohol

• Periodontal (Gum) Disease

Advanced gum disease leads to bone loss around the teeth. An OPG shows the extent of this damage, guiding surgical or non-surgical treatment.

Prevention Tips:

1. Maintain strict oral hygiene
2. Get professional dental cleanings twice a year
3. Don’t ignore early signs like bleeding gums or bad breath

• Orthodontic Assessment (Braces or Aligners)

Before placing braces or aligners, an OPG helps orthodontists evaluate tooth alignment, root structure, and jaw symmetry.

Prevention Tips:

1. While some orthodontic issues are hereditary, early dental visits (by age 7) can help guide proper jaw and tooth development, reducing the need for extensive correction later.

• Cysts, Tumors, or Congenital Anomalies

Anomalies in jawbone structure, benign tumours, or cysts may develop silently. OPG can detect these changes early.

Prevention Tips:

1. Routine dental visits help detect abnormal growths. Avoid tobacco and limit alcohol consumption to reduce oral cancer risk.

General Preventive Measures for Oral Health

Below are the mentioned general preventive measures for oral health: 

• Brush Twice Daily with Fluoride Toothpaste: Use a soft-bristled brush and replace it every 3 months.
• Floss Daily: Flossing removes plaque and debris between teeth, preventing gum disease and decay.
• Limit Sugar and Acidic Foods: Frequent snacking on sugary foods promotes plaque buildup and cavities.
• Avoid Tobacco Products: Smoking increases the risk of gum disease, tooth loss, and oral cancers.
• Visit the Dentist Every 6 Months: Routine check-ups catch early problems before they become serious.
• Use Mouthguards When Needed: Protect your teeth during sports or if you grind your teeth at night.
