Gingivitis: Causes, Symptoms and Treatment Options
Gingivitis is the earliest stage of gum disease. It occurs when plaque bacteria accumulate along the gumline, irritating and inflaming the surrounding gum tissue. One of the most common signs is bleeding gums during brushing or flossing.
Gingivitis is common and may develop gradually without causing pain. Professional dental assessment helps determine the extent of gum inflammation and the most appropriate course of care.
Professional Gum Assessment
A thorough clinical evaluation can assess gum health, identify signs of inflammation, and help determine whether treatment may be beneficial.

What Is Gingivitis?
Gingivitis is inflammation of the gums caused by the accumulation of bacterial plaque along the gumline. When plaque is not effectively removed through daily brushing and interdental cleaning, the bacteria within it trigger an inflammatory response in the surrounding gum tissue. The gums may become swollen, red, and prone to bleeding — particularly during brushing or flossing.
Gum Inflammation
Plaque bacteria provoke an immune response in the gum tissue, causing inflammation. This inflammatory process leads to the characteristic redness, swelling, and tenderness that patients may notice around the gumline. The gums may feel sensitive or uncomfortable when touched.
Bleeding Gums
One of the most recognisable signs of gingivitis is bleeding during brushing or flossing. Healthy gum tissue typically does not bleed during normal oral hygiene, so regular bleeding is often an early indicator that gum inflammation may be present and warrants professional evaluation.
Generally Reversible
Unlike more advanced periodontal disease, gingivitis does not involve permanent damage to the bone or tooth-supporting structures. With appropriate professional care and improved oral hygiene, gingivitis is often considered reversible — making early assessment and intervention particularly valuable.
A can evaluate gum health, identify signs of inflammation, and help determine whether gingivitis or another gum condition may be present.
Common Causes of Gingivitis
The primary cause of gingivitis is the accumulation of plaque bacteria along the gumline. However, several contributing factors may increase the likelihood of developing gum inflammation or make it more difficult to manage effectively.
1Plaque Build-Up Due to Inadequate Oral Hygiene
Plaque is a soft, sticky film of bacteria that forms continuously on the tooth surfaces. When it is not removed through effective daily brushing and interdental cleaning, it accumulates along the gumline and triggers an inflammatory response in the surrounding tissue. This is the most common pathway to gingivitis development.
2Tartar (Calculus) Accumulation
When plaque remains on the teeth for an extended period, it may harden into tartar — also known as calculus. Tartar cannot be removed by brushing alone and requires professional dental cleaning. Its rough surface provides an ideal environment for further plaque accumulation, perpetuating the cycle of gum inflammation.
3Smoking and Tobacco Use
Smoking is a significant risk factor for gum disease. It reduces blood flow to the gum tissue, impairs the immune response, and can mask symptoms such as bleeding — potentially delaying recognition of the condition. Tobacco use in any form may make gingivitis more difficult to manage and increase the risk of progression to periodontitis.
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. Pregnancy gingivitis is a well-recognised example of this association.
5Certain Medical Conditions and Medications
Some systemic conditions — including diabetes and certain immune disorders — may increase susceptibility to gum disease. Additionally, some medications can affect gum health by reducing saliva production or causing gum tissue overgrowth, both of which may contribute to an increased risk of gingivitis.
Understanding the factors contributing to gum inflammation can help guide effective management. A professional assessment can identify the specific causes relevant to your situation.
Symptoms of Gingivitis
Gingivitis may develop gradually and, in its early stages, may not cause significant discomfort. Being aware of the common signs can help you recognise when professional evaluation may be appropriate.
Bleeding Gums When Brushing or Flossing
This is often the first noticeable sign of gingivitis. If your gums regularly bleed during brushing or when you use interdental brushes or floss, it may indicate that the gum tissue is inflamed and responding to bacterial irritation along the gumline.
Red or Swollen Gums
Healthy gums are typically a pale pink colour and firm in texture. Gums affected by gingivitis may appear darker, redder, or more swollen than usual — particularly along the margin where the gum meets the tooth.
Tender Gum Tissue
Inflamed gums may feel tender or sensitive when touched, during brushing, or when eating certain foods. This tenderness reflects the inflammatory response occurring within the gum tissue.
Persistent Bad Breath
Bacteria associated with plaque and gingivitis can produce volatile sulphur compounds that contribute to persistent bad breath (halitosis). If bad breath persists despite good oral hygiene, it may indicate underlying gum inflammation.
Additional Signs to Monitor
While the symptoms listed are the most common indicators of gingivitis, you may also notice the following. These do not necessarily indicate a serious problem, but professional evaluation can provide clarity.
Gum irritation around particular teeth or dental restorations
Gums that appear to be receding from the tooth surface
A change in the colour of gum tissue from pink to red or purple
Sensitivity when consuming hot, cold, or sweet foods
Plaque or tartar visible along the gumline
An unpleasant taste in the mouth
Gingivitis symptoms may be subtle initially. If you notice any persistent changes in your gum health, professional assessment can help determine the cause and guide appropriate care.
When Dental Assessment May Be Recommended
While occasional, minor gum bleeding may not always indicate a significant problem, certain patterns and persistent symptoms may benefit from professional dental evaluation. Early assessment is particularly valuable because gingivitis is often considered reversible with appropriate care.
Assessment and management of gingivitis and bleeding gums 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 improve with brushing and mouthwash may indicate bacterial accumulation associated with gum inflammation.
If your gums become tender or uncomfortable — particularly around specific teeth or areas — professional assessment can help identify the cause and determine appropriate care.
Treatment Options for Gingivitis
Treatment for gingivitis depends on the clinical findings during examination and aims to reduce gum inflammation, remove bacterial deposits, and support long-term gum health. The approach is tailored to each patient's individual needs.
Professional Cleaning and Care
Professional dental cleaning (scale and polish) to remove plaque and tartar deposits that cannot be addressed by brushing alone.
Subgingival scaling may be recommended if tartar has accumulated below the gumline, allowing the gum tissue to heal more effectively.
Personalised oral hygiene instruction, including guidance on brushing technique, interdental cleaning, and the use of appropriate dental products.
Application of antimicrobial agents may be considered in certain cases to help reduce bacterial load.
Ongoing Monitoring and Maintenance
Following initial treatment, monitoring gum health at regular intervals may help reduce the risk of gingivitis recurring. Your dental team may recommend more frequent hygiene appointments initially, with the interval adjusted as gum health improves.
Periodontal maintenance may be recommended if gum inflammation persists or if there are factors that increase the risk of progression. This involves regular professional cleaning and assessment of gum health over time.
Treatment depends on clinical findings and individual circumstances. Your dentist or hygienist can advise on the most appropriate care plan following a thorough assessment.
Preventing Gingivitis
Effective prevention of gingivitis centres on consistent daily oral hygiene and regular professional dental care. The following measures may help reduce the risk of gum inflammation developing or recurring.
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 from aggressive brushing.
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, identify early signs of inflammation, and remove any plaque or tartar that has accumulated despite home care. Your dentist can advise on the most appropriate appointment frequency.
4Avoid Tobacco Products
Smoking and tobacco use significantly increase the risk of gum disease and may impair the body's ability to respond to 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 bleeding gums or other symptoms of gingivitis, the following general measures 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 and frequency of gum bleeding.
Arrange professional dental assessment if symptoms persist or worsen.
Avoid
Do not brush aggressively — this may damage gum tissue further rather than resolving inflammation.
Avoid stopping flossing because of bleeding — gentle interdental cleaning helps reduce plaque accumulation.
Do not rely solely on mouthwash to address gum inflammation without professional assessment.
Avoid ignoring persistent bleeding — it is not a normal part of oral hygiene.
Do not delay dental assessment if bleeding is accompanied by swelling, pain, or recession.
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.
