Q. Hi there – I am 50 and have a crown on one of my front “eye” teeth. It’s 25 years old. My front teeth overproject. My dentist has told me it would be unethical for him to replace my crown without doing about £10,000 of orthodontal work first. I have the detailed photos he took and could send them to you. I would like to improve the appearance of my teeth but am reluctant to do so much to them and in some ways my overbite is beneficial I think to my face shape. I would like a second opinion but if from the sight of the photos I am a hopeless case then I will just keep what I have!
