This was a significant development in the history of Britain, and England specifically. King Alfred of the Kingdom of Wessex (later known as Alfred the Great) led the resistance to the Viking invasion. In doing so he was able to unite under his kingship the other Anglo-Saxon kingdoms that were not subject to Danish law. He thus established a united English kingdom (although it was probably called the kingdom of the Anglo-Saxons or something similar).
Soothe sore gums with chamomile tea. Put one tea bag of chamomile in a cup of boiling water. Allow to to steep for five minutes and cool slightly before drinking. Swish the tea around your mouth to sooth your gums before swallowing.
Warm and cold compresses can provide quick relief for sore, swollen gums as they help reduce pain and swelling. You need to hold the compresses against your face, not directly on the swollen gums. Soak a clean cloth in warm water and wring out the excess liquid. Hold the cloth against your face for 5 minutes.
