They hurt, they interrupt your eating, and they seem to come back. Here is what actually causes canker sores and what genuinely speeds up healing.

Canker sores are not cold sores. They appear inside your mouth. They are white or grey with a red border. They are not contagious.

Accidental bites damage your mouth lining. So do sharp foods like chips and crusty bread. Even vigorous tooth brushing can cause micro-tears.

Stress weakens your immune system. This is one of the biggest triggers for recurring canker sores.

Food sensitivities play a role. Citrus fruits, tomatoes, chocolate, and coffee are common culprits. Pay attention to what you ate before a sore appeared.

Low iron, zinc, or vitamin B12 can trigger canker sores. Your body needs these to repair mouth tissue.

Visit your GP for a blood test if you get sores often. Correcting a deficiency often stops the cycle.

Some people get canker sores when their diet lacks folate. Leafy greens and legumes help fill the gap.

Most canker sores heal on their own in seven to fourteen days. But you can manage the pain while waiting.

Use an antiseptic mouthwash. This reduces irritation and prevents infection. Your dentist can recommend the right one.

Apply a protective paste or gel. This creates a barrier over the sore. It lets you eat and talk without constant pain.

Avoid toothpaste with sodium lauryl sulphate. This ingredient irritates some people's mouths and worsens sores.

Do not pick at or bite the sore. This delays healing and risks infection.

Very hot, spicy, or acidic foods make it worse. Stick to bland, cool, soft foods while healing.

See your dentist if a sore lasts longer than three weeks. Persistent sores need investigation.

Sores larger than one centimetre need professional attention. So do sores that spread or come with a fever.

Recurring sores every month may signal an underlying issue. Your dentist helps identify the cause.
