Can Stress Cause Canker Sores?  

Canker sores can be a real pain, literally. These sores, which have a white appearance with a red border can occur out of nowhere and be extremely painful. They are not contagious and as of yet, there is no definite reason for their appearance. One common denominator that has been noticed, however, is stress. There is no treatment or prevention for these sores, simply staying away from acidic foods, watching your stress levels and washing your mouth out with an antimicrobial mouthwash can help to ease the pain.

How Stress is a Factor

Stress is a factor in many illnesses throughout the body. It is the main cause of a diminished immune system, which could be causing canker sores. When your body is not operating at its best, viruses and bacteria can take over, causing different issues throughout your body and mouth. Canker sores are suggested to be one of those issues. When you are stressed, your body is unable to fight off the germs that it would normally fight off, which results in sores throughout your mouth.

Fighting the Stress

The key factors in decreasing the outbreak of canker sores in your mouth is getting adequate sleep, eating a healthy diet and finding an outlet for your stress. These simple remedies may not prevent canker sores altogether, but they will give your body a fighting chance at avoiding them, at least frequent occurrences.

Home Remedies for Canker Sores

If you do end up with an outbreak of canker sores, there are simple ways that you can diminish the pain. Keeping your mouth clean is an essential component, which means brushing and flossing at least twice a day. When you brush your teeth, be very careful around the sore. Use a soft brush with very little pressure to help keep the area clean without harming the sore. Along with watching your diet, you should keep the consumption of spicy foods to a minimum, apply ice to the area if the pain is unbearable or use over-the-counter numbing agents to temporarily handle the pain.
