I got a single tooth implant and not happy with the result. Is there something that can be done to make it look better? (photo)

Hi, thanks for write... Of course you could change this crown, go to your dentist and tell him about your needs or ask him the name of the implant to inform another dentist if you don't want to come to the same. Good luck 

Simple solution would be to redo the crown.  It is too rounded, doesn't quite match the shape of the others which are flatter and have sharper edges.  Bigger problem is that there is not symmetry with gum heights so this tooth will always appear shorter.  Again, start by redoing the crown and see if you can get a result that simply blends with the surrounding teeth.

From the picture it looks like the tooth is too short compared to the real tooth #10 and that its too bulky.  Also the gum looks like there is a depression above the tooth.  I think that the implant position is not ideal and that you had resorption of some bone above the implant.  The site was not ideal before the implant was placed and the placement may have been not deep enough for a titanium implant.  This sometimes happens with these types of implants.   If the crown is made longer it may darker at the gumline.  This is partly the reason we use ceramic implants in the front of the mouth.

The photo does not look very good but it is remarkable that the crown on your right is greater than the next, doctors must take into account (especially in the front teeth) study models for better precision and crown size . To solve nonconformity You could change the crown or see if you have enough coverage to mold.

Hard to tell form your picture but either your crown is too big due to some gum recession in which case you can lengthen the other tooth or the whole procedure needs to be redone. I hope you can salvage what is there.
