Gum Disease: Causes, Symptoms and Treatment Options
Gum disease is a common condition affecting the tissues that support the teeth. It begins with inflammation of the gums caused by plaque build-up, and early stages may cause redness, swelling, and bleeding when brushing.
Without appropriate care, gum disease may progress to deeper periodontal problems. Professional dental assessment helps identify the stage of gum disease and determine the most appropriate course of care.
Professional Gum Assessment
A thorough clinical evaluation can assess gum health, identify signs of disease, and help determine whether treatment may be beneficial.

What Is Gum Disease?
Gum disease is an inflammatory condition affecting the gum tissue and the supporting structures of the teeth. It develops when bacteria accumulate in dental plaque along the gumline, triggering an immune response that causes the gums to become inflamed. Early gum inflammation is known as gingivitis, while more advanced disease affecting deeper tissues and bone is called periodontitis.
Bacterial Plaque
Gum disease begins with the accumulation of bacterial plaque — a soft, sticky film that forms continuously on tooth surfaces. When plaque is not effectively removed through daily brushing and interdental cleaning, the bacteria within it produce toxins that irritate and inflame the surrounding gum tissue.
Inflammatory Response
The body responds to plaque bacteria by increasing blood flow to the affected gum tissue, causing redness, swelling, and tenderness. This inflammatory response is the hallmark of gingivitis and explains why inflamed gums bleed more easily during brushing or flossing.
Early Stages May Be Reversible
In its early stage — gingivitis — gum disease has not yet caused permanent damage to the bone or supporting structures. With appropriate professional care and improved oral hygiene, early gum disease is often considered reversible, which is why early detection and assessment are particularly valuable.
A can evaluate gum health, identify signs of disease, and help determine the most appropriate care pathway for your individual situation.
Stages of Gum Disease
Gum disease exists on a spectrum, from mild gum inflammation to more advanced periodontal conditions. Understanding the stages can help you recognise the importance of early assessment and timely care.
Gingivitis
Gingivitis is the earliest stage of gum disease, involving inflammation of the gum tissue without permanent damage to the bone or tooth-supporting structures.
Inflammation and redness of the gums
Bleeding during brushing or flossing
Gum tenderness or mild swelling
No permanent bone loss or structural damage
Often considered reversible with appropriate care
Periodontitis
Periodontitis is a more advanced form of gum disease where the infection has spread beyond the gums to affect the deeper supporting tissues and bone.
Infection affecting deeper gum tissues and bone
Formation of periodontal pockets between gums and teeth
Gum recession — teeth may appear longer
Possible tooth mobility in advanced cases
Not reversible, but can be managed and stabilised
The progression from gingivitis to periodontitis is not inevitable. Early professional assessment and appropriate care may help prevent the condition from advancing to more serious stages.
Common Causes of Gum Disease
The primary cause of gum disease is the accumulation of bacterial plaque along the gumline. However, several contributing factors may increase susceptibility to gum inflammation or make it more difficult to manage effectively.
1Plaque and Tartar Accumulation
Bacterial plaque is the primary trigger for gum disease. When plaque is not effectively removed through daily brushing and interdental cleaning, it hardens into tartar (calculus), which cannot be removed by brushing alone and requires professional cleaning. Tartar provides a rough surface that encourages further plaque accumulation and gum irritation.
2Inadequate Oral Hygiene
Inconsistent or ineffective brushing and flossing allows plaque to accumulate along the gumline and between the teeth. Without regular removal, plaque bacteria trigger the inflammatory response that leads to gum disease. Developing effective daily hygiene habits is one of the most important factors in preventing gum disease.
3Smoking and Tobacco Use
Smoking is one of the most significant risk factors for gum disease. It reduces blood flow to the gum tissue, impairs the immune response, can mask early symptoms such as bleeding, and may make treatment less effective. Tobacco use in any form increases the likelihood of developing periodontal problems.
4Hormonal Changes
Hormonal fluctuations during puberty, pregnancy, menstruation, and menopause can increase the sensitivity of gum tissue to plaque bacteria. This heightened sensitivity may make the gums more susceptible to inflammation, even with otherwise adequate oral hygiene practices.
5Medical Conditions and Medications
Certain systemic conditions — including diabetes, immune disorders, and cardiovascular disease — may increase susceptibility to gum disease. Some medications can also affect gum health by reducing saliva production or causing gum tissue changes, both of which may contribute to an increased risk of gum inflammation.
Symptoms of Gum Disease
Gum disease may develop gradually and, particularly in its early stages, may not cause significant pain. Being aware of the common signs can help you recognise when professional assessment may be appropriate.
Bleeding Gums During Brushing or Flossing
This is often the first noticeable sign of gum disease. Healthy gums do not typically bleed during normal oral hygiene. Regular bleeding may indicate that the gum tissue is inflamed and responding to bacterial irritation.
Red or Swollen Gums
Healthy gums are generally a pale pink colour and firm in texture. Gums affected by disease may appear darker, redder, or more swollen — particularly along the gumline where plaque tends to accumulate.
Persistent Bad Breath
Bacteria associated with gum disease produce volatile compounds that can cause persistent bad breath (halitosis). If bad breath continues despite good oral hygiene, it may indicate underlying gum inflammation or periodontal pockets harbouring bacteria.
Gum Recession
As gum disease progresses, the gum tissue may recede or pull away from the teeth, making the teeth appear longer. Recession may also expose the root surfaces of the teeth, which can lead to increased sensitivity.
Advanced Symptoms
In more advanced stages of gum disease, additional symptoms may develop. These signs typically indicate that the condition has progressed beyond gingivitis and may warrant prompt professional evaluation.
Loose teeth or teeth that feel less stable
Changes in how the teeth fit together when biting
Pus or discharge between the gums and teeth
Increasing gaps appearing between the teeth
Pain or tenderness when chewing
Dental restorations that no longer fit properly
Symptoms vary between individuals. If you notice persistent changes in your gum health, professional assessment can help determine the cause and guide appropriate care.
When Dental Assessment May Be Recommended
While gum disease may develop without causing significant discomfort in its early stages, certain signs and patterns may indicate that professional evaluation would be beneficial. Early assessment is particularly valuable because gingivitis is often considered manageable with appropriate care.
Assessment and management of gum disease are available at our London clinic, where professional evaluation can determine the most appropriate course of care.
Consider Assessment If:
Regular bleeding during brushing or flossing — rather than occasional minor bleeding — may suggest ongoing gum inflammation that could benefit from professional evaluation and cleaning.
If your gums remain swollen, red, or tender despite maintaining regular oral hygiene, there may be plaque or tartar accumulation that requires professional removal.
Chronic halitosis that does not respond to brushing and mouthwash may indicate bacterial accumulation in periodontal pockets or other gum disease-related changes.
If you notice that your gums appear to be receding or pulling away from the teeth, this may suggest that gum disease has progressed beyond the early inflammatory stage.
Treatment Options for Gum Disease
Treatment for gum disease depends on the clinical findings during examination and aims to control inflammation, remove bacterial deposits, and support the long-term health of the gums and supporting structures. The approach is tailored to the stage and severity of each patient's condition.
Professional Cleaning and Hygiene
Professional dental cleaning (scale and polish) to remove plaque and tartar deposits that cannot be addressed by brushing alone.
Subgingival scaling to remove tartar below the gumline, allowing the gum tissue to heal and reattach more closely to the tooth surface.
Personalised oral hygiene instruction, including guidance on brushing technique, interdental cleaning, and product selection.
Dietary and lifestyle advice where relevant factors — such as smoking — may be contributing to gum disease.
Periodontal Treatment and Monitoring
For more advanced gum disease, periodontal treatment may be recommended to manage infection in deeper tissues. This may help control gum inflammation and aims to stabilise the condition to prevent further progression.
Ongoing monitoring and maintenance appointments are often an important part of managing gum disease. Regular professional assessment allows your dental team to track progress, identify any changes, and adjust care as needed.
Treatment depends on clinical findings and individual circumstances. Your dentist or hygienist can advise on the most appropriate care plan following thorough assessment.
Preventing Gum Disease
Effective prevention of gum disease centres on consistent daily oral hygiene and regular professional dental care. The following measures may help reduce the risk of gum disease developing or progressing.
1Brush Twice Daily
Brushing teeth at least twice daily with a fluoride toothpaste helps remove plaque before it can accumulate and cause gum irritation. Using a soft-bristled toothbrush and gentle circular motions along the gumline may help reduce the risk of both plaque build-up and gum tissue damage.
2Clean Between Teeth Daily
Interdental cleaning — using floss, interdental brushes, or other appropriate devices — removes plaque from areas between the teeth that a toothbrush cannot effectively reach. These areas are particularly susceptible to plaque accumulation and gum inflammation.
3Attend Regular Dental Appointments
Routine dental examinations and professional hygiene appointments allow your dental team to monitor gum health, detect early signs of disease, and remove any plaque or tartar that has accumulated. Your dentist can advise on the most appropriate appointment frequency for your needs.
4Avoid Tobacco Products
Smoking and tobacco use significantly increase the risk of gum disease and may impair the body's ability to manage gum inflammation. Avoiding tobacco products is one of the most effective steps for supporting long-term gum health.
Temporary Precautions Before Dental Assessment
If you are concerned about gum disease symptoms, the following general precautions may help maintain gum health while professional assessment is arranged. These do not replace professional dental care.
Recommended
Maintain consistent brushing twice daily with a fluoride toothpaste.
Continue flossing or using interdental brushes, even if gums bleed slightly.
Use a soft-bristled toothbrush and gentle technique to avoid further irritation.
Monitor the pattern of gum bleeding, swelling, or other changes.
Arrange professional dental assessment if symptoms persist or worsen.
Avoid
Do not stop brushing or flossing because of gum bleeding — gentle cleaning helps reduce plaque.
Avoid smoking or tobacco use, which impairs gum healing and increases disease risk.
Do not brush aggressively — this may damage gum tissue rather than resolve inflammation.
Avoid relying solely on mouthwash to address gum disease without professional assessment.
Do not delay seeking assessment if symptoms such as persistent bleeding, recession, or loose teeth develop.
These measures are general guidance only and do not replace professional dental care. If you are concerned about your gum health, please contact us to arrange an assessment.
