Homeopathy Treatment for Canker Sores

Aphthae are painful blisters on the oral mucosa. They stand alone or in groups. They occur mainly in the context of infections, but can also occur without any other illness. Mouth ulcers usually go away on their own within two weeks. However, there is a great risk of relapse. The cause of the development of aphthae is unknown. Stress, infections and some foods are considered triggers for the development of the painful blisters. Homeopathic remedies support the healing of aphthae and serve to relieve pain.
