Good Mouthwash Will Brushing Everyday And Using Good Mouthwash Prevent A Tooth Abscess?

Will brushing everyday and using good mouthwash prevent a tooth abscess? - good mouthwash

I have a hole in the tooth, and it has been for some time (not remember exactly, but about a year, maybe), but never any pain or discomfort, so I ignored. So I suddenly have a psychosis in ruins, and I think now I'm crazy to think, "What if I have an abscessed tooth?" My question, the brushes and mouthwash (Crest ProHealth, to be exact) in order to prevent abscessed tooth?
