What's the best temporary solution for filling in a gap between my upper canine tooth and the first premolar? (photo)

My dentist and I have discussed getting invisalign 6 months down the road to treat lower teeth crowding. I need know whats a temporary solution for fixing this gap that I have...I am very self-conscious about it and I am getting married in July. I have heard of composite bonding...am I a good candidate for it? If yes, does this affect my decision to get invisalign down the road.
