Common Causes of Canker Sores

Posted in Laser Dentistry

Ulcers and canker sores are usually very uncomfortable, and can take several days for them to heal themselves. Although some people only get them from time to time, other people get them on a more regular basis. It’s important to understand risk factors and causes that may result in a higher rate of canker sores for some people.

Increased sun exposure, stressful conditions, or recent illness can weaken the immune system and cause people to be more susceptible to developing ulcers, cold sores, and canker sores. Obviously stress isn’t always avoidable, but if it’s a chronic problem then some lifestyle changes may be needed.

Foods that are acidic, such as tomatoes make some people’s oral tissues irritated and develop sores. If you currently deal with heartburn, you may need to be seeing a doctor to alleviate the additional acid that is making its way up to your mouth.

Braces and orthodontic appliances are often known for causing irritation from rubbing the inside of the lips and cheeks. Using orthodontic wax or having minor adjustments made can protect the tissues that repeatedly become irritated in specific areas.

Believe it or not, many dentists are now providing a fast, effective laser dentistry treatment for tissue irritations like ulcers, canker sores, and cold sores with soft tissue laser therapy. These lasers halt the ulcer formation instantly, and in just a few seconds result in alleviated pain. The sore then heals extremely quickly, and the patient’s discomfort is completely reversed. The treatment just takes a few seconds, and can be integrated into any visit that is already scheduled at the office. Or, just feel free to call your dentist to see if you can be worked in for a quick 5-minute visit!
