Dental implant gone wrong! The dentist installed implant but the tooth is higher and larger than the other front tooth (Photo)

See a periodontist and prosthodontist for another opinion about how to fix this problem. This is a common problem that I have seen over the years when treatment is not planned out properly. Gum reaction is forecast PRIOR to implant placement and crown cementation. Now, depending on the severity of the gum recession and possible bone loss, it is possible that the whole treatment might have to be redone in order to achieve a satisfactory result. If you are lucky, a simple gum graft might help. But it is not clear what can be done based on your photo. If you could submit a better photo we might be able to see better. 

first thing i want to tell u is , its a artificial structure and not natural one  so never expect excellent result like natural from artificial things. in usa and canada people go for implants frequently ,but never consider as a last treatment option. now come to point. in yr case its because of bone loss in implant region [ prior to implant placement] , thats why implant placed bit up. u can achieve ideal result by implant placement followed by gum surgery for proper bone creation. that is not possible with bone graft . in yr kind of cases it is possible to create ideal bone by taking bone piece from other body part and placing at implant side. in this procedure also results are not always as per expectation , so u have to consider this thing.now u have two options 1. just replace crown , and tell yr dentist to add pink gum shade in gingival area[camouflage] or.2. remove implant , follow treatment as i described above.

Sorry to hear that you are not happy with your dental implant restoration.  It does appear that there were some complication.  Implants in the cosmetic zone can be quite complicated.  I would suggest you find a specialist in your area and have a consultation with them to see what can be done to correct the cosmetic concerns.  Good luck

Sorry to hear about your implant and crown.This is a complication that happens sometimes with implants in the front because of the thin bone and gum in this area.  Its not very clear from your picture but it seems like the gums receded after the crown was placed.  There are various reasons for this from extra cement trapped under the gum, to gum recession caused by bone recession.  Most of the time and most people don't show the gum that high when they smile so the problem is hidden but in some with a high smile this is a very serious issue.  The best is to go back to your dentist and see when he suggests, if he can't do anything consult with a dental surgeon that has experience with treatment front teeth with dental implants.  Good luck and let me know if I can help any further.
