Hi I had

Hi I had unstraight front teeth and asked my dentist about straightening them, he suggested crowns. I went ahead and had them done about 2 years ago. I’m not happy, the colour is yellow, one sticks out slightly, they feel too far forward and that affects my speech (I spray spit) I’m now totally conscious of them, rarely smile or chat as it’s so embarrassing. I also have gum disease which I’m trying to get under control. I’ve since moved dentists and my current one says nothing can be done re crowns while gum disease is evident. I’m losing the will to live and just hate my teeth. What can I do? I’m desperate and happy to pay to get the perfect smile I’m looking for.
