Swollen Gums: Causes, Symptoms and Treatment Options
Swollen gums occur when the gum tissue becomes inflamed or irritated, causing the gums to appear red, enlarged, or tender. Gum swelling is often linked to plaque accumulation along the gumline, though other factors may also contribute.
In some cases, swelling may indicate gum disease or infection. Professional dental assessment helps identify the underlying cause and determine appropriate care.
Professional Assessment
A thorough clinical examination can assess gum health, identify areas of inflammation, and help determine the most appropriate course of care.

What Causes Swollen Gums?
Gum swelling typically occurs when bacteria accumulate around the gumline, triggering the body’s immune response. This inflammatory reaction may cause fluid build-up within the gum tissue, making the gums appear enlarged, puffy, or tender. The swelling often indicates underlying gum irritation or infection that may benefit from professional assessment.
Bacterial Plaque Response
When bacterial plaque builds up along the gumline, the immune system responds by sending blood flow and inflammatory cells to the area. This natural defence mechanism causes the gum tissue to become red, swollen, and more sensitive. Without intervention, the inflammation may persist and potentially progress.
Fluid and Tissue Changes
The inflammatory process can cause fluid to accumulate within the gum tissue, leading to a puffy or enlarged appearance. The gums may lose their firm, stippled texture and instead appear smooth and swollen. These tissue changes are typically a sign that the gums are responding to an irritant.
Early Warning Sign
Swollen gums often serve as an early indicator that oral health may need attention. The swelling may be localised to one area or affect multiple sites around the mouth. Identifying and addressing the cause of inflammation early may help support long-term gum health and reduce the risk of progression.

Common Causes of Swollen Gums
Bacterial plaque is often the primary cause of gum inflammation, but several other factors may contribute to gum swelling. Understanding these contributing factors can help inform discussions with your dentist and support preventive care.
1Plaque and Tartar Accumulation
Bacterial plaque that is not effectively removed through daily brushing and flossing can accumulate along the gumline and trigger inflammation. Over time, plaque may harden into tartar (calculus), which cannot be removed at home and provides a rough surface that attracts further bacterial deposits. Professional cleaning is needed to remove tartar and help reduce associated inflammation.
2Gingivitis (Early Gum Disease)
Gingivitis is the earliest stage of gum disease, characterised by inflammation of the gum tissue without damage to the underlying bone. Swollen, red, or bleeding gums are hallmark symptoms of gingivitis. With appropriate professional care and improved oral hygiene, gingivitis is often considered reversible at this stage.
3Food Debris Trapped Between Teeth
Particles of food that become lodged between teeth or beneath the gumline can cause localised irritation and swelling. This type of inflammation is typically limited to a specific area and may be accompanied by discomfort or a feeling of pressure. Effective interdental cleaning can help prevent this type of gum irritation.
4Irritation From Dental Appliances
Dental appliances such as dentures, retainers, or orthodontic brackets may occasionally irritate the gum tissue through friction or pressure. If an appliance does not fit correctly or has a rough edge, the surrounding gum tissue may become swollen or sore. Your dentist can assess the fit and make adjustments where needed.
5Hormonal Changes
Hormonal fluctuations — such as those occurring during pregnancy, puberty, or the menstrual cycle — can increase blood flow to the gums and make the tissue more sensitive to bacterial plaque. This heightened sensitivity may cause the gums to swell more readily in response to even small amounts of plaque. Maintaining good oral hygiene during these periods is particularly important.
Professional appointments play a key role in removing plaque and tartar deposits that may be contributing to gum inflammation.
Symptoms Associated With Swollen Gums
Gum swelling may be accompanied by a range of associated symptoms. Being aware of these signs can support earlier recognition and timely professional assessment.
Enlarged or Puffy Gum Tissue
Healthy gums are typically firm and pale pink with a stippled texture. When inflamed, the gum tissue may appear puffy, swollen, or enlarged. The gums may extend further over the tooth surface than usual, and the normal contour of the gumline may be altered.
Redness Around the Gumline
Inflamed gums often change colour from their normal pale pink to a deeper red or reddish-purple. This colour change is caused by increased blood flow to the area as part of the inflammatory response. The redness may affect a localised area or extend along sections of the gumline.
Tenderness When Brushing or Eating
Swollen gums may feel tender or uncomfortable when touched, particularly during brushing or when eating certain foods. This sensitivity is a result of the inflammatory process making the gum tissue more responsive to pressure and stimulation.
Bleeding Gums and Bad Breath
Bleeding during brushing or flossing is a common sign of gum inflammation. The inflamed tissue is more fragile and may bleed with gentle contact. Persistent bad breath (halitosis) may also develop as bacteria accumulate in areas of inflammation, producing volatile compounds.
When Dental Assessment May Be Recommended
Professional evaluation may be appropriate if you notice any of the following. These signs do not necessarily indicate a serious problem, but timely assessment can help identify the cause and support informed decisions about care.
Gum swelling persists for several days without improvement
Bleeding gums accompany the swelling, particularly during brushing
Pain or discomfort develops in the swollen area
Gum swelling appears to spread to surrounding areas
Persistent bad breath develops alongside gum inflammation
The swelling affects eating, speaking, or daily comfort
Assessment and management of swollen gums are available at our London clinic, where professional evaluation can determine the most appropriate course of care.
Treatment Options for Swollen Gums
Treatment for swollen gums depends on the underlying cause, which is determined through professional clinical examination. The aim of treatment is to address the source of inflammation, support gum health, and help prevent recurrence.
Your dentist will assess the gum tissue, check for signs of gum disease, and recommend the most appropriate approach based on clinical findings specific to your situation.
Treatment Approaches
Thorough removal of plaque and tartar deposits from above and below the gumline may help reduce gum inflammation. Professional cleaning reaches areas that are difficult to access through home care alone and aims to create a cleaner environment for the gum tissue to heal.
Where gum disease is identified as the cause of swelling, periodontal treatment aims to manage the underlying infection. This may include deep cleaning procedures to treat gum pockets and reduce bacterial accumulation beneath the gumline, supporting gum and bone health.
Your dentist or hygienist can provide personalised advice on improved brushing and interdental cleaning techniques. Effective daily oral hygiene aims to support gum health between professional appointments and reduce the risk of inflammation recurring.
Regular dental visits allow your dentist to monitor gum health over time, assess whether inflammation has resolved, and detect any changes early. This ongoing evaluation helps ensure that any recurrence of swelling is addressed promptly.
Preventing Gum Swelling
Maintaining good oral hygiene practices and attending regular professional dental care can help reduce the risk of gum inflammation and support long-term gum health. The following measures work alongside professional dental care.
Daily Oral Hygiene
Brush teeth twice daily with fluoride toothpaste, paying careful attention to the gumline area.
Use a soft-bristled toothbrush and gentle technique to effectively clean without irritating the gums.
Clean between teeth daily using floss or interdental brushes to remove plaque from areas the toothbrush cannot reach.
Consider using an antibacterial mouthwash as part of your oral care routine — your dentist can recommend suitable products.
Professional Care
Regular help monitor gum health and identify early signs of inflammation before they progress.
Professional remove plaque and tartar deposits that cannot be effectively managed through home care alone, reducing the bacterial load along the gumline.
Your dentist or hygienist can assess your individual risk factors and provide personalised advice on the most effective preventive care for your situation.
Maintaining good oral hygiene habits between professional visits supports the long-term health of the gum tissue and helps reduce the risk of recurring inflammation.
Temporary Precautions Before Dental Assessment
If you have noticed swollen gums, the following general precautions may help support gum comfort while professional assessment is arranged. These measures do not replace professional dental care.
Recommended
Maintain consistent brushing twice daily, paying careful attention to the gumline.
Continue flossing or using interdental brushes daily, even if gums are slightly tender.
Use a soft-bristled toothbrush and gentle brushing technique to avoid further irritation.
Stay hydrated to help support saliva production and oral health.
Arrange professional dental assessment if swelling persists beyond a few days.
Avoid
Avoid aggressive brushing, which may further irritate inflamed gums rather than improve them.
Do not use a hard-bristled toothbrush, as this may worsen gum tissue damage.
Avoid ignoring persistent gum swelling or bleeding — professional assessment can help identify the cause.
Do not attempt to remove tartar at home — only professional cleaning can safely remove hardened deposits.
Avoid delaying assessment if swelling is accompanied by pain, spreading, or increasing bleeding.
These precautions are general guidance only and do not replace professional dental care. If you are concerned about swollen gums, please contact us to arrange an assessment.
