Periodontitis: Causes, Symptoms and Treatment Options

Periodontitis is an advanced stage of gum disease that affects the tissues and bone supporting the teeth. It usually develops from untreated gingivitis, when bacterial plaque beneath the gumline leads to inflammation and damage to supporting structures.

Over time, the condition may affect gum attachment and bone levels around teeth. Professional dental assessment helps determine the severity of periodontal disease and appropriate management.

Professional Assessment

A thorough periodontal examination can help assess gum health, measure pocket depths, and evaluate bone levels to determine the most appropriate course of care.

Understanding the Condition

What Is Periodontitis?

Periodontitis is a chronic inflammatory condition affecting the gums and the bone that supports the teeth. It develops when bacterial plaque accumulates beneath the gumline, triggering an immune response that may damage gum tissue and surrounding bone over time. This may gradually lead to reduced support for affected teeth.

Bacterial Inflammation

Periodontitis is driven by the accumulation of bacterial plaque beneath the gumline. The body’s immune response to these bacteria causes chronic inflammation that, over time, can break down the connective tissue and bone supporting the teeth. Unlike gingivitis, the damage caused by periodontitis is not reversible.

Progression From Gingivitis

Periodontitis typically develops after a period of untreated gingivitis. While gingivitis involves surface-level gum inflammation that is often reversible, periodontitis represents the spread of infection to the deeper supporting structures. Early intervention at the gingivitis stage may help reduce the risk of progression.

Bone and Tissue Loss

As periodontitis progresses, the gum tissue may pull away from the teeth, forming periodontal pockets that harbour bacteria. The supporting bone may gradually reduce in height and density, potentially leading to tooth mobility. Professional treatment aims to stabilise the condition and support the retention of affected teeth.

Periodontitis typically develops gradually, and symptoms may not always be immediately obvious. A can assess gum health and help identify whether periodontal disease is present.

Contributing Factors

Common Causes of Periodontitis

While bacterial plaque is the primary trigger for periodontitis, several factors may increase the risk of developing the condition or influence its progression. Understanding these contributing factors can support preventive care and early intervention.

1Long-Term Plaque and Tartar Accumulation

Bacterial plaque that is not removed through daily brushing and flossing can harden into tartar (calculus), which cannot be removed at home. Tartar provides a rough surface that attracts further plaque accumulation and makes effective cleaning more difficult. Over time, the bacterial deposits beneath the gumline may trigger the inflammatory process that leads to periodontitis.

2Untreated Gingivitis

Periodontitis most commonly develops from gingivitis that has not been adequately managed. When early gum inflammation persists without appropriate care, the infection may spread to deeper tissues and bone. Regular professional cleaning and good oral hygiene practices may help address gingivitis before it has the opportunity to progress.

3Smoking and Tobacco Use

Smoking is one of the most significant risk factors for periodontal disease. It reduces blood flow to the gum tissue, impairs the immune response, and can make treatment less effective. Tobacco use in any form may accelerate the progression of periodontitis and reduce the body's ability to heal following treatment.

4Genetic Susceptibility

Some individuals may be genetically more susceptible to periodontal disease, even with good oral hygiene practices. A family history of gum disease or tooth loss may indicate an increased predisposition. For these patients, more frequent professional monitoring and preventive care may be particularly important.

5Certain Medical Conditions

Medical conditions that affect the immune system or inflammatory response — such as diabetes, cardiovascular disease, or autoimmune conditions — may influence gum health and increase the risk of periodontal disease. Some medications may also affect the gums. Your dentist can take your medical history into account when assessing your periodontal health.

Professional appointments play a key role in removing bacterial deposits and supporting the prevention of periodontal disease.

Recognising the Signs

Symptoms of Periodontitis

Periodontitis may develop gradually, and symptoms can sometimes go unnoticed in the early stages. Being aware of the following signs may help with earlier recognition and timely professional assessment.

1

Persistent Gum Inflammation

Gums that remain red, swollen, or tender over an extended period may indicate ongoing periodontal inflammation. Unlike occasional irritation from brushing, persistent inflammation suggests a chronic condition that may benefit from professional assessment and management.

2

Gum Recession

As periodontitis progresses, the gum tissue may recede — pulling away from the teeth and causing them to appear longer than before. Gum recession exposes the root surfaces of the teeth, which may increase sensitivity and alter the appearance of the smile.

3

Bleeding Gums During Brushing

While occasional bleeding may occur from vigorous brushing, regular or persistent bleeding during brushing or flossing is a common symptom of gum disease. This bleeding indicates that the gum tissue is inflamed and may warrant professional evaluation.

4

Persistent Bad Breath and Loose Teeth

Bacteria accumulating in periodontal pockets can produce volatile compounds that cause persistent bad breath (halitosis) that does not resolve with regular brushing. In more advanced cases, teeth may begin to feel loose or shift position as the supporting bone diminishes.

When Dental Assessment May Be Recommended

Professional evaluation may be appropriate if you notice any of the following. These signs do not necessarily confirm periodontitis, but timely assessment can help identify the cause and support informed decisions about care.

Gum recession becomes noticeable, causing teeth to appear longer

Teeth feel loose, unstable, or seem to shift position

Gum bleeding persists despite careful brushing and flossing

Bad breath becomes persistent and does not resolve with oral hygiene

Changes in bite alignment or how the teeth fit together occur

Spaces develop between teeth that were not previously present

Assessment and management of advanced gum disease are available at our London clinic, where professional evaluation can determine the most appropriate course of care.

Clinical Management

Treatment Options for Periodontitis

Treatment for periodontitis depends on clinical examination and the severity of the condition. The aim of periodontal treatment is to control inflammation, reduce bacterial accumulation, and help prevent further progression of bone and tissue loss.

Your dentist or hygienist will assess the condition through periodontal probing, clinical examination, and possibly radiographic imaging to determine the most appropriate treatment pathway for your individual situation.

Treatment Approaches

Professional Periodontal Cleaning

Thorough removal of plaque and tartar deposits from above and below the gumline. This may help control periodontal inflammation and reduce bacterial accumulation in areas that are difficult to reach through home care alone.

Deep Cleaning (Root Surface Debridement)

For deeper gum pockets, specialised cleaning procedures may be used to remove bacterial deposits from the root surfaces beneath the gums. This aims to support gum and bone health by creating an environment that is less favourable for bacterial growth.

Monitoring Gum and Bone Health

Regular clinical assessments — including periodontal probing and, where appropriate, radiographic imaging — help monitor gum pocket depths and bone levels over time. This ongoing evaluation guides treatment decisions and helps detect any changes early.

Supportive Periodontal Therapy

Following initial treatment, ongoing maintenance appointments are typically recommended to manage disease progression. These visits involve professional cleaning, reassessment of periodontal health, and reinforcement of home care techniques.

Extraction When Necessary

In cases where teeth have lost significant support and cannot be effectively maintained, extraction may be considered as part of the overall management plan. Your dentist will discuss all options and the rationale for any recommendations.

Long-Term Management

Importance of Ongoing Periodontal Care

Periodontitis is typically a long-term condition that requires ongoing monitoring and professional maintenance. While active treatment aims to control inflammation and stabilise the condition, continued care plays an essential role in managing periodontal health over time.

Why Maintenance Matters

Periodontitis is a chronic condition — treatment aims to manage the disease rather than eliminate it entirely.

Regular professional cleaning helps reduce bacterial accumulation in areas that are difficult to reach through home care.

Ongoing monitoring allows early detection of any changes in gum pocket depths or bone levels.

Maintenance visits provide an opportunity to reinforce oral hygiene techniques and address any areas of concern.

Supporting Long-Term Gum Health

Patients with periodontitis typically benefit from more frequent professional care than the standard six-monthly schedule. Depending on the severity of the condition, appointments every three to four months may be recommended.

Good daily oral hygiene — including thorough brushing and interdental cleaning — remains an important part of managing periodontal health between professional visits. Your dentist or hygienist can provide personalised guidance on the most effective techniques for your situation.

Professional appointments play a central role in supportive periodontal therapy, helping to maintain the improvements achieved through initial treatment.

General Guidance

Temporary Precautions Before Dental Assessment

If you suspect you may have signs of periodontal disease, the following general precautions may support your oral health while professional assessment is arranged. These measures do not replace professional dental care.

Recommended

Maintain careful brushing twice daily, using a soft-bristled brush and gentle technique along the gumline.

Continue flossing or using interdental brushes daily to clean between teeth and beneath the gumline.

Avoid smoking or tobacco use, as these significantly affect gum health and the body's ability to manage inflammation.

Monitor any changes in gum health, tooth stability, or the appearance of your gums, and note these for your dental appointment.

Arrange professional dental assessment if symptoms such as bleeding, recession, or loose teeth persist.

Avoid

Do not attempt to remove tartar at home — only professional cleaning can safely remove hardened deposits from below the gumline.

Avoid using sharp instruments to probe around the gums or teeth, as this may cause further tissue damage.

Do not ignore persistent gum bleeding, recession, or tooth mobility — these symptoms may indicate a condition that benefits from professional assessment.

Avoid vigorous or aggressive brushing, which may further irritate inflamed gums rather than improve them.

Do not delay seeking professional care if you notice changes in tooth stability or increasing gum recession.

These precautions are general guidance only and do not replace professional dental care. If you are concerned about gum health, please contact us to arrange a periodontal assessment.
