Help me! I'm going mad! Mika's just started teething and in true Mika stile she's not doing things by halves, not one not two but FOUR teeth are coming

At first i thought i got it wrong so i got my mum to tlook and she said she can see 3 but feel four and when my sister came up she said she can see all four. So it looks like she's getting all four of her top teeth in one go. Needless to say i was up every half hour last night with a screaming Mika.
I've used calpol, teething gel, teething rings and teething biscuits but nothing seems to be helping her. My poor bubba i guess i'm just going to have to let nature take it's course
