Refusal to cover dental treatment although funds available.

Its really disappointing, 1stly the authorisation process that you are subjected to as a member of the medshield medical aid. It really feels like it defeats the purpose of having a medical aid, when in the event of an emergency you are told that authorisation can only be recieved 5-7 working days, of which is never a guarantuee. Why have medical aid and then take such a risk? In the past weeks i have been experiencing extreme sensitivity on my tooth. I then went to a specialist dentist who said my margins are defective and that he would suggest i get treatment including getting a crown. The medical aid simply declined, siting, because i have a gold tooth, they refuse to cover the costs, also stating that the Gold caused the tooth sensitivity, which according to my dental specialist, is completely false. In essence, i have a medical aid, i have not touched the funds but have to pay a couple of thousands, from my own pocket to get the issue sorted out. I have never been a member of a medical aid with so many excuses when it comes to fulfilling its purpose for medical funds assistance. I would not recommend medshield to anybody who wishes to get peace of mind and value for money.
