I love this these tabs! They’re compact, effective, and plastic free. I’ve been using them for close to a year now and feel my teeth have become less sensitive to cold or sweet foods. I also used to get sores on my tongue with tube toothpaste, I assumed it was a reaction from the intensity of the mint flavoring and/or combination of chemicals. These tabs are minty, but not overwhelming and I haven’t had this problem since using them. Highly recommend!
