Hi and
I have to say, I agree with ScaredStiff - she usually offers great advice. I think that your best bet is to back off for now. You can't force somebody to do something they're afraid of doing without risking really alienating them. Facing the prospect of marriage and planning a wedding is a lot to take in, in and of itself. It may be that your fiancé has enough on his plate to deal with at the moment.
To help your fiancé, try to relate to his fear. What is the thing that frightens
you the most? Maybe you're afraid of snakes. Now, think about how you would feel if someone told you that you have to go into a room full of mostly benign snakes but that somewhere in there, there are a few poisonous snakes. Oh, and by the way, you'll have to pay $15,000 for the privilege. Sound appealing? To a non-phobic, that scenario would sound like an over-exaggeration. I can tell you, though, that the dental phobics on this website would probably tell you that they'd just as soon or maybe even rather take their chances with the snakes than to visit a dentist.
Dental phobia is not really a matter of willpower. Certainly, it takes willpower to get in through the door but there is often a host of emotional issues that need to be dealt with (consciously or sub-consciously) before a person can even contemplate going through with dental care. As ScaredStiff said, for most of us, there is some precipitating event that gets us to finally visit a dentist. It really does have to be something that your fiancé eventually decides to do for himself.
Brit has offered some great advice, too. However, I wouldn't look at your wedding as a bargaining chip, as such. Utimatums can really backfire...especially if he thinks that your love of him is contingent on his getting his teeth fixed. Dental phobia isn't usually the sort of thing that a person says, "Oh, well in that case, I'll do it." At the same time, I agree with Brit's suggestion that you could ask him if he would feel better if you postponed the wedding and use the finances to take care of his dental health. But, even this is a slippery slope and is a subject you should raise carefully - making sure to stress that your love and your desire to get married have nothing to do with his teeth.
I applaud your efforts to help your fiancé and your willingness to look for compromises, such as your losing ten pounds. However, unless you are terrified of losing weight for some reason and you think it will cost you $15,000 to lose the weight, it's not really likely to be an exchange that will prove to be particularly motivating for your fiancé.
Weight loss and overcoming dental phobia do have something in common - both are much less about willpower than they are about dealing with emotional issues that keep us in an unhealthy holding pattern. In both cases, the individual has to come to the conclusion that they are no longer willing to stay "stuck". Most people, however, don't reach that type of conclusion on anybody else's time table. You may be ready to lose weight right now but it sounds like your fiancé is not ready to face his fear yet.
The best way you can help your fiancé isn't through bargaining, threats, or badgering. Rather, let your fiancé know that you love him no matter what his teeth look like. You can tell him that you're concerned for his health and well-being and that it saddens you to see him embarrassed by his teeth and the toll that embarrassment takes on his self-confidence. Set a good example with your own oral hygiene. Tell your fiancé that you'll be with him every step of the way when he is ready to face this challenge. Bring up the subject only occasionally. Other than that, be compassionate and patient and remember all of the wonderful qualities that made you fall in love with this man to begin with.
Your fiancé is a very lucky man to have such wonderful support available to him. Given your support and the fact that he has had successful experiences in the past, I think that in time your fiancé will eventually be ready to face this hurdle.
