If more hyaluronic acid filler is added to one side, it can be dissolved to make the sides even and to reduce the swelling. This is done by injecting hyaluronidase where the filler was previously injected. It is a simple procedure. 

Normally the lab would remove the surface layer of the porcelain and replace it with a lighter shade porcelain. This is an easy and common lab procedure. 

It is important to evaluate the bridge in relation to your occlusal plane and the plant/level of the upper teeth. All these elements should coordinate perfectly together otherwise you would have biter interference. Your best reference is your dentist as he/she has all the details. Express your concern at a follow up visit and ask for explanation. Good luck. 

Botox cannot be used to close gaps between teeth. We inject fillers into the gum papillae to close such gaps. Results are great but usually last till you body absorbs the filler. However, a detailed exam and measuring of the gaps are determining factors in suitability of such treatment. 

Crowns in the smile area may need a different approach. The margin of the crown can be made in porcelain so that no dark line shows. Another option it to make an all porcelain crown with no metal.
