Hello, As the situation is time bound you can think of getting the gaps closed cosmetically. Minor spaces can be closed using a restorative material.

Veneers are best options instead of crown or bridge , either you go for veneers or for ortho treatment even it takes time . Yes marriage is a important part of life but health is more important than any other things. Your hurry will compromised health of teeth.

Veneer Laminates Pfm or metal free crowns Componeer

Given your time frame - digitally designed  cosmetic treatments - smile designing -  are the best option.

U can go for laminate or veneers

Can be done. Laminates could be good option. But need to check clinically if its possible or not.

One inch???? Sounds too much and I hope it is a typing error. A proper case evaluation is required and there are multiple options which can give you the desired results but the applicability of any treatment protocol can be just after evaluating the case only. Please visit a dentist for this without delay because the treatment is going to be multistep and will take time of its own. Regards.
