Despite having no trouble with her front teeth, my dd was in some discomfort for over a week with the molars coming in. I thought I better have her checked by the doctor as it had been going on for so long. He confirmed it was teething and prescibed ibuprofen syrup. I thought I'd pass this on as the ibuprofen seems to work much better than calpol or teething gel which really had no effect and it's worth going to the doctor even with something like teething as there are things they can do
