Sore gums: causes, care and when to see a dentist

Sore gums can make brushing and eating uncomfortable. Plaque-related gum inflammation is one possible cause, but an ulcer, an injury or a problem around an erupting tooth can also hurt. Pain alone cannot tell you what is wrong.

Arrange a dental appointment if your gums are painful, swollen or repeatedly bleed. Gum disease can also develop with little discomfort, so the absence of pain does not mean that everything is healthy.

What might be causing the soreness?

Plaque can irritate the gum edges, causing gingivitis. More advanced gum disease affects the tissues supporting the teeth and needs a different level of care. A dentist can assess this by examining your mouth and, where needed, taking measurements and X-rays.

Local soreness may follow vigorous brushing, floss being forced into the gum or rubbing from an appliance. Do not assume that every painful area is caused by inadequate cleaning. A dental examination can distinguish irritation from infection or another condition.

Hormonal changes during pregnancy can make gums more susceptible to inflammation. Diabetes, smoking and some medicines can also affect gum health. Tell the dentist about your health and medication, but do not stop prescribed treatment on your own. Sore gums are not enough to diagnose a vitamin deficiency.

When does it need urgent help?

Seek an urgent dental appointment for severe pain or swelling, pus, fever, or a suspected dental abscess. If you cannot get urgent dental care, contact NHS 111. Do not wait until the pain becomes unbearable or keep trying home remedies while swelling gets worse.

Call 999 or go to A&E if swelling makes it difficult to breathe, speak or swallow, or affects your eye or vision. Extensive mouth swelling or marked difficulty opening your mouth also needs emergency assessment. The NHS dental abscess guidance explains these warning signs.

After an extraction, follow the instructions you were given. Some discomfort may be expected, but worsening pain or swelling, fever or persistent bleeding should be checked rather than dismissed as normal healing.

Caring for sore gums at home

Keep cleaning gently with a soft toothbrush and fluoride toothpaste. Ask the dental team which interdental brushes or floss suit the spaces between your teeth and how to use them without injuring the gum. Do not force a brush into a space or snap floss down onto a sore area.

Choose foods that are comfortable to eat while you arrange care. A pharmacist can advise on suitable pain relief, taking account of your medical history and other medicines. Follow the label and do not put aspirin or other tablets directly against the gum.

Herbal rinses and gum massage do not treat the cause of an abscess or established gum disease. Do not use a gum massager to press on a painful swelling. Antiseptic mouthwash is not a replacement for cleaning or dental treatment; use it only as advised for your situation.

How will the dentist help?

Treatment depends on the cause. It may involve advice on cleaning, professional removal of deposits, treating a problem tooth or adjusting an appliance. More advanced gum disease may need further treatment or referral. Antibiotics are not a routine answer to every sore gum.

Tell the team if anxiety has made it difficult to attend. You can discuss taking breaks and ways to make the examination easier. Seeking help should not mean being blamed for the problem.

Once the cause has been addressed, agree an individual review schedule. Persistent or recurrent symptoms need reassessment rather than waiting for a routine six-month visit. Contact us to arrange an appointment for sore or bleeding gums.
