Unfortunately you are in a difficult situation.. It sounds as though fixed brace work is unacceptable to you with question marks on how you will be able to maintain you oral health whilst it is in place. Regular visits during treatment would be a great help but obviously with a cost implication.

Without seeing your mouth it is difficult to give you constructive advice. Having said that bonding may be a help to you. This is where the dentist adds tooth coloured filling material to your teeth to improve their appearance. The whole front of the tooth can be covered with this material forming a composite veneer. Some tooth preparation may be necessary to get the best result possible. This is a much cheaper option than placing porcelain ;veneers but is very technique sensitive. You may want to discuss this option with your dentist or alternatively find a cosmetic dentist who has the proper training to carry this procedure out.

Hope this helps,

Regards,
