You get canker sores regularly and want to understand why. They're not cold sores — they're aphthous ulcers with distinct triggers. Here's what most commonly causes them and how to reduce how often you get them.

Canker sores are small, painful ulcers that form inside your mouth — on your cheeks, tongue, or gums. Unlike cold sores, they're not contagious. But they sure are annoying.

Common Triggers for Canker Sores

Certain foods are frequent culprits. Citrus fruits, tomatoes, chocolate, coffee, and spicy foods can all trigger a sore. Even crunchy foods like chips can nick the inside of your mouth and set one off.

Stress is another big trigger. When you're run down or anxious, your immune system takes a hit — and canker sores often follow. Many people notice they pop up during exam time, work deadlines, or after a sleepless night.

Hormonal changes matter too. Some women get canker sores around their menstrual period. Others notice them during pregnancy or menopause.

Nutritional Deficiencies That Play a Role

Low iron, zinc, vitamin B12, and folate levels can all contribute. If you get canker sores often, it might be worth asking your doctor about a blood test to check these levels.

Even mild deficiencies can make your mouth tissue less resilient. Your body can't repair minor damage as quickly — and that's when ulcers form.

How to Reduce How Often You Get Them

Start by avoiding your personal trigger foods. Keep a small notebook or just pay attention to what you ate before a sore appeared. Patterns usually emerge quickly.

Manage stress with whatever works for you — exercise, better sleep, or just carving out a few minutes of quiet time each day. Your mouth reflects what the rest of your body feels.

Use a soft-bristled toothbrush to avoid irritating your mouth tissue. And consider switching to a toothpaste without sodium lauryl sulfate — this foaming agent can trigger sores in some people.

If you get canker sores that are large, extremely painful, or last more than two weeks, book a dental appointment. We can check for underlying issues and talk about prescription options if needed.

Most people get occasional canker sores that clear up on their own within 7-10 days. But if they're disrupting your life, there are things we can do.
