I cannot recommend a dental pod enough for your retainers! I used to always use my toothbrush to clean my retainers and this has changed my life. My retainers are sooo clean. I use it together with the cleaning tablets from ‘’retainer fresh''.

100% would recommend even if you don't use the dental pods with it. My retainers are loving it. I get the 120 tablets on amazon and it's great value!
