Painful ulcers or canker sores are sometimes found within the mouth. Usually there is only one ulcer, but occassionally several ulcers may develop at once. These may arise from several different causes, such as poor oral hygiene, nutritional deficiencies, worry, insufficient rest and heavy smoking. Any slight pressure on the gums may cause bleeding. Ulcerations may form on the gums and about the mouth, particularly between the teeth. Swallowing and talking are painful, there may be excessive salivation and bad breath, and the inflammation may extend to the tonsils and throat. A mild fever may be present in this condition. The first sign of the sore may be a tingling, burning sensation inside the mouth. They can occur either singly or in groups. They are usually white or yellow in color, surrounded by red halos. Usually they heal within 7 to 10 days. The recurrent, bothersome form of mouth ulcers is known as recurrent apthous stomatitis or simply apthous ulcer. They take several more days to heal. There may be a family history to develop canker sores, as they often run in families. Mouth ulcers may develop in response to a mouth injury such as dental procedures or aggressive tooth cleaning. Canker sores may also occur at the site of a bite when the tongue or cheek is bitten. They can be triggered by emotional stress, dietary deficiencies (especially iron, folic acid, or vitamin B12), menstrual periods, hormonal changes, food allergies, and similar situations. They occur most commonly with viral infections. The membrane of the mouth may be very dry or exceedingly moist. There is pain on nursing, eating or drinking; the pain varies according to the condition or stage of the disease. The pains may be sharp or sticking if the mouth is dry or smarting and raw if the mouth is full of saliva. These ulcers may be broad and superficial or deep and narrow. Small ulcers may combine together and may form large ulcers on the side of the tongue or in the buccal cavities.

Orange juice is helpful in preventing the canker sores of the mouth. Drink it up in 2 or 3 days it will go away. Lack of vitamin C causes them. You can also take Vitamin C pills if you don't want to drink all that orange juice.

Mix Sodium bicarbonate powder with water. It is a very effective first aid remedy. This mixture can be used as a mouth rinse as well as swallowed to help make the body more alkaline.
Use a toothpaste containing sodium bicarbonate instead of the standard toothpastes high in fluoride and other chemicals.
Antacids can soothe canker sores by reducing the acidity in your mouth that can irritate them.
Combine equal parts of the liquid form of Kaopectate or Milk of Magnesia (both antacids) with Benylin or Benadryl (both mild anesthetics). Apply the mixture to the canker sore with a cotton swab. You'll cut down on painful acidity in your mouth and numb the sore too.
Try stress-relieving acupressure exercises. Avoid constant stress. Take time to exercise, sleep and relax.
Avoid eating fish or meat of any kind for two weeks. The consumption of animal protein increases the body's acidity, which slows healing.
Avoid chewing gum, lozenges, mouthwashes, tobacco, coffee, citrus fruits, and any other foods that you know trigger these sores.
Avoid hard toothbrush bristles or sharp-edged foods such as potato chips or dry bread crusts. Too much acid from fruits and vegetables, and spicy foods can also trigger mouth sores.
Keep the bowels regular to prevent toxic buildup. Walk regularly walking in fresh air to oxygenate the body and stimulate bowel movement.
To avoid getting canker sores, it is important to maintain a proper balance of minerals, acidity, and alkalinity in the body.
