Periodontal Disease Stages

Periodontal disease, also known as gum disease, is a serious oral health condition that affects the gums and bones supporting your teeth. It can cause pain, swelling, and even tooth loss. With early detection and prompt treatment, periodontal disease can often be managed successfully. It’s important to understand the stages of periodontal disease to know what to look out for and when to seek professional help. In this blog post, we will discuss the stages of periodontal disease in detail so that you have all the information you need to protect your smile.

Stages of Periodontal Disease

Periodontal disease develops when bacteria accumulate in the form of plaque along the gum line. Over time, bacteria in plaque produce toxins that irritate the gums, leading to inflammation and infection. Periodontal disease can progress through various stages, each stage is associated with different symptoms and treatment approaches.

Periodontal disease can be classified into four stages:

  • Gingivitis: The gums are red, swollen, and bleed easily, but there is no bone loss.
  • Mild Periodontitis: Plaque and tartar build-up below the gum line. Periodontal pockets may develop, which are spaces between the teeth and gums.
  • Moderate Periodontitis: Deeper pockets form, and bone loss may occur.
  • Advanced Periodontitis: teeth become loose or fall out due to severe bone loss.


Gingivitis is the first stage of periodontal disease characterized by swollen, red, and bleeding gums. This happens when the bacteria in plaque build up and cause inflammation.

Early gum disease stage, gingivitis, can be reversed with professional teeth cleaning and proper oral hygiene habits. However, if gingivitis is not treated, it can progress into periodontitis, which can cause irreversible damage to the teeth-supporting bone and tissues.

Periodontitis: Advanced Stages of Periodontal Disease

Periodontitis is the advanced stage of the periodontal disease characterized by inflammation and infection of the supporting structures of the teeth, such as the gums, bones, and ligaments. It is usually caused by poor oral hygiene habits that allow plaque to build up in the mouth. Periodontitis has three stages; mild, moderate, and severe.

In the mild stage of periodontitis, the infection spreads to the tooth-supporting tissues, causing the formation of spaces between teeth and gums, known as periodontal pockets.

In a healthy mouth, the normal pocket depth is less than 3mm. When mild periodontitis develops, the pockets can deepen to 4-5mm. These pockets can trap food and bacteria because they are difficult to clean, leading to further damage.

In the moderate stage of periodontitis, the infection continues to spread. The pockets deepen further, becoming 6 to 7mm in depth. Along with this deepening, the gums begin to recede from the teeth, making them look longer. Bone loss is also present at this stage and may become significant in X-rays.

The advanced stage of periodontitis is characterized by severe gum and bone loss. The pockets are greater than 7mm in depth. As bone loss continues, teeth may become loose and eventually fall out. Also, an abscess may develop around the teeth and gums due to the ongoing infection. Treatment at this stage is more complex and usually requires surgery.

It is important to get periodontal disease treatment as soon as possible to prevent it from progressing to more serious stages.

A periodontist measures the depth of a periodontal pocket.
The deeper the pockets, the more advanced the stages of periodontal disease.

When to See a Dentist?

If you are experiencing any of the signs and symptoms associated with periodontal disease, it is important to see your dentist. Depending on the severity of the condition, they may refer you to a periodontist for further evaluation and treatment.

A periodontist is a specialist who focuses on the diagnosis and treatment of diseases that affect the gums and other structures that support the teeth.

Signs and symptoms that can indicate periodontal disease include:

  • Red, swollen, or tender gums
  • Gums that bleed easily when you brush or floss
  • Receding gums
  • Pus between the teeth and gums
  • Persistent bad breath
  • A change in the way your teeth fit together when you bite
  • Loose teeth or tooth loss

How are The Different Stages of Periodontal Disease Treated?

The treatment aims to control the infection and stop periodontal disease from progressing to more serious stages. Treatment depends on the severity of the condition, which may include:

  • Gingivitis: This stage is typically treated with improved oral hygiene practices and professional cleaning (regular cleaning).
  • Mild Periodontitis: Treatment includes scaling and root planing (deep periodontal cleaning) to remove the plaque and tartar (hardened plaque) from above and below the gum line.
  • Moderate Periodontitis: This stage is treated with more extensive scaling and root planing, along with antibiotic medications that are placed directly into the periodontal pockets. Osseous surgery may also be required in some cases to reduce pocket depths or to repair damaged tissue.
  • Advanced Periodontitis: At this stage, osseous surgery is usually necessary to reduce pocket depths and repair damaged tissues. Bone or tissue grafts may be required to help regenerate lost tissues. These procedures can be combined with gingivectomy and gingivoplasty for periodontitis. In addition, your periodontist may be prescribed antibiotics to help control the infection. In severe cases, tooth extraction may be necessary.

Periodontal disease can progress very quickly, so it is important to recognize the four stages and take action as soon as possible. If you have any signs or symptoms of periodontal disease, be sure to see a dentist or periodontist right away. With early detection and treatment, you can avoid the worst consequences of this serious condition.

Home Care

Proper home care is essential for controlling and preventing periodontal disease. Brushing and flossing twice a day should always be part of your routine, but more aggressive measures may need to be taken depending on the severity of the disease. For example, your periodontist may recommend an antimicrobial rinse, antibiotic gel, or a medicated toothpaste.

You should also pay special attention to your diet. Eating a balanced diet that is low in sugar and high in vitamins and minerals will help your body fight off infections. Additionally, quitting smoking will help improve your oral health, so it’s important to be aware of the risk factors associated with periodontal disease.

Additionally, you should visit your periodontist regularly for regular check-ups and professional cleaning and monitor the healing process.

Periodontal Disease Stages – Conclusion

Stages of periodontal disease can range from mild gingivitis to severe periodontitis. No matter what stage you are in, it is important to seek treatment as soon as possible to prevent further damage and maintain overall oral health.

If left untreated, periodontal disease can lead the damage of the tooth-supporting tissues and bone and eventually tooth loss.

Early detection and prompt treatment are keys to preventing periodontal disease from progressing to more serious stages. Therefore, visit your dentist regularly for check-ups and professional teeth cleaning. They can detect signs of periodontal disease and provide the necessary treatment.
