Hi there,
Is there any way that retainers cause cavities? I always brush my teeth regularly, probably even more now I have my retainer. I clean the retainer with toothpaste and a brush, and I rinse with antiseptic mouth wash. But for some reason I still have cavities on my back, lower teeth. Can you explain this? I don’t really get it because I have always brushed my teeth and never had a cavity until I got my braces off and started wearing retainers at night. Is there anything I can do to prevent this or am I doing something wrong? I thought maybe it could be the build up of bacteria over night but this has never been an issue before? Thanks
