Canker Sores Explained by our Teddington Dentists

Canker sores, also known as mouth ulcers or aphthous ulcers, are small, painful sores that can make eating, drinking or even talking uncomfortable. While they're usually harmless and clear up on their own, recurring or severe cases can be frustrating.

At Church Road Dental Care Centre in Teddington, our team often helps patients manage and prevent canker sores with expert advice and gentle care. If you're concerned about the regular appearance of ulcers in your mouth, make an appointment and we'll give you some preventative guidance to help avoid them in future.

What are canker sores and how to prevent them

What causes canker sores?

Canker sores can develop for several reasons, and sometimes it's a combination of factors. Common causes include:

• Minor mouth injuries - such as accidentally biting your cheek, irritation from braces or harsh toothbrushing.
• Stress or fatigue - emotional stress and lack of rest can weaken your immune system, making sores more likely.
• Nutritional deficiencies - low levels of vitamin B12, zinc, iron or folic acid can contribute.
• Food sensitivities - acidic or spicy foods, like citrus fruits or tomatoes, can trigger irritation in some people.
• Hormonal changes - many people experience mouth ulcers at certain times during their menstrual cycle.
• Underlying health conditions - persistent sores can sometimes be linked to gastrointestinal or autoimmune issues, so it's always worth checking with your dentist or GP if they occur frequently.

How to prevent canker sores

While not all canker sores can be avoided, there are simple steps you can take to reduce your risk and ease discomfort:

• Maintain good oral hygiene - brush gently with a soft-bristled toothbrush and fluoride toothpaste.
• Avoid known triggers - limit spicy, salty or acidic foods that may irritate your mouth.
• Manage stress - relaxation techniques such as deep breathing or yoga can make a difference.
• Eat a balanced diet - include foods rich in vitamins and minerals to support oral and immune health.
• Stay hydrated - drinking water helps keep your mouth clean and reduces irritation.
• Use alcohol-free mouthwash - this can soothe your mouth without causing stinging.

If you develop a canker sore that lasts more than two weeks, becomes unusually large, or is accompanied by symptoms such as fever or swollen glands, it's important to seek professional advice. 0208 977 3746">Contact us so we can examine it, and we may also recommend you see your GP to rule out any underlying health issues.
