Nursing hurting again - teething?

Bri

My 4 month old (EBF baby) has started to hurt again when he nurses. We did have a hard time in the beginning (lip tie, latching incorrectly) but that stopped around 10 weeks. Now whenever he latched and nurses it hurts! They’re so sore

I didn’t experience anything like this with my first. He was honestly a picture perfect baby for nursing. Anyway, could this be teething related? I have notice him gnawing on everything and extra drool too
