[|Human|] I am using gap bands to close the gap between my two front teeth. It is almost closed but now its almost like a bubble behind my two front teeth and its very tender in the middle of my two front teeth. Am I stopping blood flow from a vein and its builing up in a bubble behind them? The skin attached to my upper lip and him are also very tender
[|AI|]  Hello. I read through your query, and accordingly I must say that nothing much to be worried here. The bubble is due to inflammation of the gums in between the teeth(interdental gingival)which usually occurs during any movement of the tooth. It will be reduced once the tooth are properly aligned and spaces are closed between the teeth. In the meantime you must follow proper oral hygiene habits and be more careful by cleaning the areas in between the tooth by using interdental brushes. Hope you are benefitted something from this reply. Have a healthy day!!!
