Baby biting nipple

So my daughter is 6 months old with 2 teeth. She bites my nipple sometimes and of course it just kills. Do I just try and power through? Did any momas out there stop breastfeeding due to this? Or your baby being super busy/active/distracted?? I really would love to breastfeed her as long as possible but it seems it keeps getting harder and harder. At the moment there can’t be any noise/sounds/people/tv/music etc while she’s feeding. Even someone walking by the room I’m nursing her in she will quickly look to see what’s going on. Nursing her at home isnt so bad , it’s while I’m on the go that’s so difficult.....
