I’m not happy with the way my teeth look after bonding. Can a top front gap be removed and go back to normal? (Photo)

Hi! There are many different options to help close up your gap. Bonding is definitely one of them but as the other doctors have suggested, it might make your teeth look unnaturally big. Make sure to discuss all of your options with your dentist. You can also get veneers but I would personally suggest Invisalign or another form of orthodontic treatment as they keep your natural teeth and this is the healthiest for us! Make sure to thoroughly discuss your options with your dentist! 

Dental bonding is very non-invasive. It's very easy to remove in most circumstances. As far as your gap, bonding can be done to close that space, but your teeth will look very wide and unnatural. It would be a better idea to consider orthodontic treatment such as braces or Invisalign to move the teeth closer together. 

Th space between your top front teeth could be closed with bonding, but it will make them look larger than they already are.  You would get a nicer, more proportionate look by veneering the front four teeth.  I would first suggest that you have the space closed with bonding and see if you like it. You can always opt for the veneers later.
