I had a massive restoration done at EKA in the autumn of 2016. In all, 21 teeth were crowned. The work was done in two stages. About 1-2 months later, one of the premolars fell out but it was re-cemented and has stayed put. Shortly after that one of the upper incisors came out and this was more problematic as I needed a root canal treatment. This was done about 16 months ago and all is fine. To be fair, this tooth already had a very large filling in it, so it was living on borrowed time.
Anyway, one has to be realistic, a 90% success rate is pretty good. I went from being someone with not very aesthetic teeth to someone with what I consider to be fantastic looking teeth.
Good. These people are professionals.
