Initial pain while feeding my 15mo

[RubberBullets]

I was very lucky and didn't have any pain when dd was a newborn, feeding was always very easy. She is now 15mo and all of a sudden I have a really intense, toe curling pain whenever she clamps on which eases during the feed. She is teething at the moment but it is teeth 15 and 16 coming and we had no problems with the others. She isn't biting me, it is just right at the start when she latches.

Is this likely to be a phase during this particular bout of teething? I want to feed her until at least 24 months but if this pain is going to happen every time from now on then it would make me consider weaning her earlier :(
