8 Home Remedies for Canker Sores

Canker sores are common, but they can be painful and annoying. Over-the-counter treatments are readily available, but there are a number of natural ways to hasten the healing process.

It is not unusual for people to develop a canker sore up to four times each year. These ulcerations develop on the inside of a lip or cheek. Canker sores are typically yellow or white in color and are surrounded by reddened inflammation. The problem can last from one to three weeks. However, in some cases, the sores may last up to six weeks. In more severe instances, the lesions may be accompanied by a fever, swollen lymph glands and general malaise.

Canker sores are not contagious. However, the precise reason for their development remains unknown. Contributing factors include stress, injury or illness. Children and adults with impaired immune systems are more prone to developing canker sores. People living with celiac or Crohn's disease are also at a higher risk. The lesions might occur secondary to complex B vitamin, iron or zinc deficiencies.

Canker Sore Dos and Don'ts

Eating acidic fruits and vegetables may cause a canker sore to appear. The foods can also irritate and make the lesion worse. Grapefruit, lemons, oranges, pineapples, tomatoes along with fermented foods all have high citric acid levels, which may erode soft tissues over time. They also aggravate canker sores and may lead to additional eruptions. The acid content of coffee is another problem along with carbonated beverages. Salty foods add to the discomfort. Nuts, chips and other sharp snack foods can damage healthy tissues and further disrupt the healing process of existing sores. Sharp areas on a tooth, braces or improperly fitting dentures can all cause soft tissue injuries, which may lead to canker sores.

Foods that are recommended in order to hasten the healing of cold sores should be rich in complex B vitamins, iron and zinc. Healthier meals may include lean meats, poultry and fish along with dark green and leafy vegetables. Beans, cheeses, milk and shellfish are also nutritious options.

Canker Sores vs. Cold Sores

Canker sores and cold sores are not the same. When sick with a cold, cold sores or fever blisters may erupt secondary to the herpes simplex 1 virus. When the virus emerges, painful blisters appear on the outside of the mouth on, above or below a lip, around the nose or under the chin area. While canker sores are not contagious, cold sores are indeed contagious.

Natural Homemade Remedies for Canker Sores

Over-the-counter treatments are available for canker sores, but natural remedies may be preferable in many cases. These types of preparations can potentially ease or eliminate a person's symptoms without the need for harsh chemicals or treatments. Most are easy to prepare and contain ingredients that are commonly found around the house.

Aloe Vera Swish for Canker Sores

In recent years, scientists have uncovered some of the secrets of the plant's health benefits. The gel contains vitamins A, complex B, C and E, and nine different minerals and phytonutrients that promote healing by providing much-needed tissue nourishment. Aloe vera additionally contains eight types of enzymes known to reduce swelling and inflammation while encouraging new cell growth. The gel also protects cells from the free radicals that cause damage and aging.

It's a miracle that I'm alive today. I encountered HERPES SIMPLEX VIRUS (HSV1/2) for good four (4) years, before I met the great Dr.okosun.
