I had 2 upper dental implants done successfully, but now I can't afford to have them crowned. (Photo)

You are not doing any damage to the implants by having them uncrowned.  The issue is the stress that you are placing on the other teeth as they are taking more forces than they should.  I would look into a financing company such as Care Credit, which would allow you to pay the implant crowns off over a period of time.  Good luck.  

Hi, thanks for the question... If you don't crowned will lose bone stability and space, but if you don't want the implants will be submerged. Try to put your implants is my recommendation. 

After having an implant placed, you should wait at least 6 months prior to placing a permanent crown.  This is to make sure that the implant has osseointegrated.  You should not wait too much longer to have the crown placed because the neighboring teeth can migrate into the empty space.  Additionally, you are missing posterior support without having a crown in that area, which causes the forces of occlusion to be weighed more heavily on the neighboring teeth.  If the implant has been there for at least 6 months, I encourage you to have the crown placed as soon as possible.

u can go for crown on implant anytime . but long time without restoration results in migration of neighbouring teeth into empty space . so it is advisable to restore as soon as possible.  dental tourism is best option for u to save money.u will save upto 70% .

I encourage my patients to get dental implants restored as soon as possible.  However, if it is not in your budget to complete the treatment you have started, the best thing to do is have a retainer made to hold your teeth in position until the implant supported crowns are completed.  The retainer will help you avoid the unwanted tooth movement that occurs when you are missing teeth.  Consistent use of the retainer can buy you the time you need to save for the crowns.  Also, Care Credit is a great option to finance treatment by breaking it down into monthly payments.
