Breastfeeding

Hello ladies and gentlemen but I have a question , my baby just turned 10 months yesterday and for the past month and a half he has not wanted to breastfeed for a long time usaly he feeds for like 5 minutes , he is eating three meals a day , but it seams like he doesn't want it is this normal ? Never has this happen with my oldest who is now 18 but hat to get him. Off cause he bit me , oh yeah the baby has two teeth could that be preventing him from feeding ?
