Owwww. It's worth treating it like the kind of nipple soreness that can happen when you have a newborn. Lansinoh will help. I always preferred olive oil, myself, because it has healing properties and is easier to apply. You might also put some calendula and / or some antibiotic cream on it, and take extra vitamin C right now to help ward off any infection. And keep a close eye on your baby's latch. Sometimes they slip up in that department when they get new teeth.<br><br>
Hope you feel better!
