Gums symbolize the dreamer’s verbal power.
If you dreamed of having sore or inflamed gums, this may symbolize an argument with friends or family in your real life.
If you were undergoing treatment on your gums in your dream, this could indicate a bitter confrontation with someone you care about.
To dream that your gums are bleeding suggests that you will say - or have already said - deeply hurtful words to someone. It can also suggest your past actions coming back to haunt you.
