I do not recommend to close a 5mm gap in 2 months.
The first thing to do have a complete exam with x-rays. What caused the gap? Is there an underlying bone or gum problem that caused this?
Bonding or veneering to close the gap can be done in one visit but it would make the teeth look way too wide and I do not recommend this.
Provided there are no other problems, this gap will take more than 2 months to close. The bone and ligaments need slow movements to avoid bone loss or root resorption. Also, the teeth and...
Closing the gap is going to require more than just bonding or veneers. You may beed a combination of orthodontics and resorative to satisfy your esthetic demands. I would consult with both a orthdontist and someone that does lots of cosmetic dentistry to see what your options are.
That is not a small gap. Bonding or veneers will not look good without ortho.
An old technique to place an ortho elastic around the centrals to tip them together. You can then bond them together and do veneers (comp or ceramic) and close the new gaps by building up the laterals. This will alllow creation of golden proportion or close with the tooth size looking appropriate.
Closing a gap can create bad esthetics if not done well.
This gap between your teeth is quite large and as it seems may be difficult to close in a hurry. It will probably require a combination of orthodontics and some veneering or bonding to close the gap completely.
