Viewer Question: Is there a connection between stress and canker sores? What can I do to get rid of them and prevent future outbreaks?
Doctor's Response: Canker sores (also called aphthous ulcers) are shallow, red or white sores that develop anywhere inside the mouth. It is not known exactly why these sores develop, but stress does seem to precipitate canker sores in many people.
Canker sores go away on their own without any treatment; however, doctors often recommend pain relievers such as ibuprofen or acetaminophen if the sores cause significant pain. There are other medications which can be applied directly to the sore to help prevent the sores from becoming further irritated and to help control pain. Many of these are the same type of medications used for teething pain in young children and babies. Examples include Anbesol, Oragel,...
Canker sores are small ulcer craters in the lining of the
mouth.
The sores are usually found on the movable parts of the
mouth.
The ulcers can be caused by a number of conditions.
The treatment of canker sores depends on the cause.
What are canker sores?
Canker sores are small ulcer craters in the lining of the mouth that are frequently painful and sensitive. Canker sores are very common. About 20% of the population (one out of five people) have canker sores at any one time. Canker sores are also medically known as aphthous ulcers or aphthous stomatitis.
Women are slightly more likely than men to have recurrent canker sores. It can occur at any age, but it is more commonly seen in teenagers. Genetic studies show that susceptibility to recurrent outbreaks of the sores is inherited in some patients. This partially explains why family members often share the condition.
Canker sores are generally classified into three groups based on size.
Minor sores have a diameter of 1millimeter (mm) to 10mm. They are the most common (80% of all canker sores) and usually last about 7-10 days.
Major sores (10% of all canker sores) have a diameter of greater than 10mm and they may take anywhere between 10-30 days to heal. They may leave a scar after they heal.
Herpetiform ulcers (10% of all canker sores) are formed by a cluster of multiple small individual sores (less than 3mm). They also usually heal within 7-10 days.
What are symptoms of canker sores?
Canker sores are usually found on the movable parts of the mouth, such as the tongue or the inside lining of the lips and cheeks, and at the base of the gums. The ulcers begin as small oval or round reddish swellings that usually burst within a day. The ruptured sores are covered by a thin white or yellow membrane and edged by a red halo. Generally, the sores heal within
two weeks without scarring. Fever is rare, and the sores are rarely associated with other diseases. Usually, a person has only one or a few canker sores at a time.
Most people experience their first bout with canker sores between the ages of 10 and 20. Children as young as 2
years old, however, can develop the condition. The frequency of canker sore recurrences varies considerably. Some people have only one or two episodes a year, while others may have a continuous series of canker sores.
Crohn's disease is a chronic inflammatory disease,
primarily involving the small and large intestine, but which can
affect other parts of the digestive system as well. Abdominal pain, diarrhea, vomiting, fever, and weight loss are
common symptoms.
Herpes simplex infections are common and when they appear around the mouth and lips, people often refer to them as "cold sores" and "fever blisters." Canker sores are different than cold sores. Air droplets can spread the virus, as can direct contact with the fluid from the blisters. Cold sore treatment include over-the-counter medication as well as prescription medications.
There are a variety of diseases and conditions that can cause tongue problems, discoloration, and soreness. Though most tongue problems are not serious. Conditions such as leukoplakia, oral thrush, and oral lichen planus may cause a white tongue while Kawasaki syndrome, scarlet fever, and geographic tongue may cause the tongue to appear red. A black hairy tongue may be caused by overgrown papillae on the tongue. Canker sores, smoking, and trauma may cause soreness of the tongue.
Stress occurs when forces from the outside world impinge on the individual. Stress is a normal part of life. However, over-stress, can be harmful. There is now speculation, as well as some evidence, that points to the abnormal stress responses as being involved in causing various diseases or conditions.
Celiac disease is a result of an immune reaction to gluten, a protein found in wheat or related grains and present in many foods that we eat. Celiac disease causes impaired absorption and digestion of nutrients through the small intestine. Signs and symptoms of celiac disease include malabsorbption (diarrhea, foul smelling gas, bloating, and increased amounts of fat in the stool) and malnutrition (weight loss, edema, anemia, bruising easily, neuropathy, and infertility). Treatment for celiac disease is a gluten free diet, and at times if necessary, medications
An allergy refers to a misguided reaction by our immune system in response to bodily contact with certain foreign substances. When these allergens come in contact with the body, it causes the immune system to develop an allergic reaction in people who are allergic to it. It is estimated that 50 million North Americans are affected by allergic conditions. The parts of the body that are prone to react to allergies include the eyes, nose, lungs, skin, and stomach. Common allergic disorders include hay fever, asthma, allergic eyes, allergic eczema, hives, and allergic shock.
Smoking is an addiction. More than 430,000 deaths occur each year in the U.S. from smoking related illnesses. Secondhand smoke or "passive smoke" also harm family members, coworkers, and others around smokers. There are a number of techniques available to assist people who want to quit smoking.
Behcet's syndrome is a disease characterized by three symptoms: genital ulcers, recurring mouth ulcers, and inflammation around the pupil of the eye. Symptoms of Behcet's syndrome may also include inflammation of other areas of the body, such as the brain, joints, skin, retina, and bowels. Oral steroids, antiinflammatory drugs, and steroid gels, pastes, and creams may be used to treat Behcet's syndrome.
Gum problems may be caused by improper brushing and flossing, gum disease, canker sores, treatments and hormonal changes. Symptoms of gum problems include red, swollen, sore and bleeding gums. These symptoms can be prevented by brushing twice a day, flossing daily, eating a well-balanced diet, drinking enough water, not smoking, and relaxing.
Herpes simplex virus (HSV) can cause infections that affect the mouth, the face, the genitals, the skin, the buttocks, and the anal area. This article will concentrate on non-genital herpes. Many people acquire the virus and have no symptoms. For others, painful blisters appear near the area where the virus entered the body. Typically, the blisters heal completely but reappear at some point in the future when least expected (or desired). In between attacks, the virus resides deep in the roots of the nerves that supply the involved area. When herpes simplex lesions appear in their most common location, around the mouth and lips, people often refer to them as "cold sores" and "fever blisters."
What causes cold sores?
There are two types of HSV, type I and type II. In general, type I, also known as herpes labialis, causes infections above the waist, most commonly as oral "cold sores." Type II infectio...
