Sore gums above new procera crowns
I had four new procera crowns fitted on my upper four front teeth in August. This was following a two month period when, for various complicated reasons, I couldn'thave permanent crowns fitted and had linked temporary units over the stumps. For the first five weeks with the new proceras, I had no problems at all. They looked and felt great. The gum that had been pushed up by the linked unit quickly grew down filling the gaps between the new crowns. Then five weeks in, the gum joining the top of the two front crowns became inflamed, red, and mishapen. It has been like this for the past month or so. My dentist says that this is not unusual with porcelain (rather than metal-topped) crowns, and that I just need to brush vigorously with an electric toothbrush, persisting even if the area bleeds. I'm trying but it's very unpleasant and i'm seeing no improvement.
Has anyone else had a similar experience with proceras? What did you do? How long did the problem last? Do you think my dentist's advice about brushing is good? It seems a little brutal. Thanks.
