Now itchy 50% of my time when resting, betw. Gum &crown edge. Eating is good. Root canaled 9 months.X-diff. To tell but seems ok.
Could be caused by an ill fitting crown which might be impinging on the gum. It would be very hard to tell without looking at the x-rays and clinical examination .
The best would be to see a dentist who can evaluate the situation. Hope that helps.
