My dentist recommended the zero alcohol to me yesterday when I said I hated mouthwash because of the intense burning sensation. There was still a burning sensation, albeit not as much, but the texture of my mouth became rough immediately after, and this morning my gums and inner cheek were peeling off in white, fleshy ribbons. They now feel raw and are still coming off when I try to eat. My mother had mentioned she had issues with Listerine in the past, and considering that it seems many people have the same issue and are even mentioning teeth browning, I don't think I'll bother letting my dad try to finish the bottle.
No, I would not recommend this product
