Swollen Gums
Red, puffy or tender gum tissue linked to plaque, infection or irritation.
What it means
Understanding swollen gums
Swollen gums look puffy, red and enlarged rather than firm and pale pink, and they can feel tender or bleed easily. Swelling is a sign of inflammation, most commonly caused by plaque building up along the gum line, but it can also be linked to infection, irritation or other factors. It may affect the whole mouth or be focused around one tooth.
In most cases, swollen gums are a sign of gum inflammation that responds well to professional cleaning and improved home care. Occasionally, localised swelling around a single tooth can indicate an infection or a trapped food particle that needs attention.
A GDC-registered dentist or hygienist can identify why your gums are swollen and recommend the most effective way to settle the inflammation.
Common causes of swollen gums
Several factors can contribute to swollen gums. Being aware of them can help — though only an examination can confirm what applies to you. Common contributing factors include:
- Plaque and tartar build-up along the gum line
- Gingivitis or more advanced gum disease
- A localised infection or gum abscess
- Food trapped between the teeth or under the gum
- Hormonal changes, such as during pregnancy
- Irritation from a rough restoration or appliance
Signs and symptoms to look out for
Symptoms vary from person to person, and some can be subtle. You may notice one or more of the following:
- Puffy, enlarged or shiny gums
- Redness rather than a healthy pink
- Tenderness or discomfort, especially when eating
- Bleeding when brushing or cleaning between teeth
- Bad breath or a bad taste
- Localised swelling around one tooth in some cases
How we assess it at our Wimpole Street practice
Because the same symptoms can have different causes, an accurate diagnosis always comes first. At Wimpole Dental, a GDC-registered dentist will listen to your concerns, examine the area and — where clinically appropriate — take X-rays or other records to understand what is happening beneath the surface. Our practice is regulated by the Care Quality Commission (CQC), and every clinician is registered with the General Dental Council (GDC).
You will then have your options explained in plain English, with a written, itemised estimate before any treatment begins — and never any pressure to proceed. Flexible payment options may be available — ask at your consultation.
What to expect when you visit us
From your very first contact, our aim is to make dental care feel calm, clear and unhurried. A member of our reception team will help you find a time that suits you, including evening and weekend appointments, and if you are in pain we will do our best to see you the same day. You are welcome as a new patient, and there is no obligation to proceed with any treatment.
At your appointment, a GDC-registered dentist will take time to understand your concerns about swollen gums, carry out a careful examination and, where clinically appropriate, take X-rays or other records. They will then explain what they have found and set out the suitable options — from doing nothing and monitoring, through to the treatments described above — so you can make an informed decision that is right for you.
If you feel anxious about visiting the dentist, you are far from alone, and we are experienced in caring for nervous patients. Please tell us how you feel when you book: we will move at your pace, explain each step before it happens, and focus on keeping you comfortable throughout. Our priority is honest, gentle care that puts your long-term health first.
Solutions & treatment options
Where swelling is due to plaque-related inflammation, a professional hygiene appointment to remove plaque and tartar, combined with an improved daily routine, usually settles the gums within a couple of weeks. Your hygienist will show you effective techniques and address contributing factors.
If the swelling is caused by a localised infection, a gum abscess or trapped debris, that specific problem is treated directly. Any rough restoration or appliance that is irritating the gum can also be adjusted.
Persistent or painful swelling, or swelling with a raised temperature, should be assessed promptly, as this can indicate an infection that needs timely care.
The treatment we most often use
Gum Disease Treatment
Structured periodontal therapy — deep cleaning, pocket charting and maintenance — designed to help halt gum disease and protect your teeth.
Prevention & everyday care
While professional care is important, good daily habits make a real difference. The following steps can help:
- Clean thoroughly along the gum line twice a day
- Clean between your teeth daily to remove trapped debris
- Attend regular hygiene appointments
- Avoid smoking
- Rinse with warm salt water to soothe mild swelling while awaiting assessment
- Report swelling that does not settle or is painful
When to see a dentist
If this sounds familiar, it's worth having it assessed early — problems are almost always simpler to treat when caught sooner. A £30 consultation lets a GDC-registered dentist find the cause and explain your options in plain English, with no pressure to proceed.
Questions & Answers
Frequently asked questions
Localised swelling around a single tooth can be caused by trapped food, a gum infection or an abscess, or irritation from a rough edge. Because these need different treatment, it is best to have the area assessed rather than waiting.
Gentle, thorough cleaning and warm salt-water rinses can help soothe mild swelling, and keeping the area clean is important. These measures support but do not replace professional care, so persistent swelling should be assessed.
Seek prompt care if swelling is painful, spreading, associated with a raised temperature, or focused around one tooth with a pimple-like spot, as these can indicate infection. Otherwise, gum swelling from inflammation is usually settled with hygiene treatment.
No. This page is general education to help you understand a common concern. It is not a diagnosis, and the same symptoms can have different causes. Only an in-person examination by a GDC-registered dentist can confirm what is happening and what, if anything, needs treating.
You will always receive a written, itemised quote before any treatment begins. New patients start with a £30 consultation; flexible payment options may be available — ask at your consultation.
