Same here! Seems to pop up every 6mo to a year, but yet nothing ever changes in the industry. I just found out I have a cavity and the dentist wants to fill it. I am trying to avoid it at all costs though, so this is pretty timely for me. The problem is that its in between my teeth, and even when I try really hard with brushing and flossing in the area, there still seems to be food particles that get in.
