Category “Q. Dental crowns”

Hi, I’m wondering if you could give me some help and advice. I have had problems with my teeth since I was young, the upper front two came through crossed. I had braces to fix this, however my teeth had been left crossed so long that some of the tooth had worn away due to decay that could not be reached, leaving me with bits missing from my front teeth. Some time after having my braces removed I got an absess over my upper front right tooth and was forced to have the nerve removed. Unfortunatly, the absess had already spread to the upper front left tooth, and that nerce had to be removed too. As you can imagine I have always felt very self concious about my teeth and planned to have cosmetic dentistry when I was older. Recently this has become finacially possible and I booked a consultation at my own dentist. However, I was told that I am not a suitable candidate for crowns, which is what I am told I would need, as I have had the nerves of both teeth removed, and any crowns fitted would be likley so fall out taking my teeth with them. I was also told I am too young to be thinking about crowns, I am 20. Is this really the case? Will my teeth fall out if I have crowns? and are there any options left open to me? I’m deperate to get them fixed. Thanks
