Potential Interactions Between Whole Milk, Mouthwash and Bonding?

Yesterday I drank some neat mouthwash (Listerine 'Zero', i.e. no alcohol), from a 250ml glass. There was about 6 tablespoons worth left over. Later on I accidentally used the same glass for some whole milk (about ¾ full), drinking through a straw. Before swallowing a second time I went to the bathroom and spat it out, then rinsed with tap water. My mouth feels sensitive. I’m worried I may have stained or damaged my teeth, dental bonding and dental implants. Many thanks for your valued time.
