My wisdom teeth never came through properly and are what the dentist days are "partially erupted". Every now and then food gets trapped and it's very painful. I suspect that what is causing me pain at the moment is either a raspberry seed or a chia seed. I have got in there with a toothbrush and had a serious go at it, trying to dislodge whatever is in there. There was blood. I will have another go later.
But if it doesn't improve, what else can I do? Bar paying £££ for an emergency dental appointment tomorrow?
