Tooth 15 is missing, and tooth 14 was extracted a few months ago. I can't afford an implant. Do I have any other options?

You have many options and converting dentures to All-On-Four type restorations should be an okay solution. I use such a restoration as a temporary fix while a more durable hybrid denture is manufactured. I would suspect that the solution which you are describing will not last a long time, but...

You should see the dentist that restored the implant as soon as possible before the gum in the area covers the screw again to avoid another exposure surgery ....

Hi Rroff175,There are certain types of implants that use a color coded system to assist the doctor during surgery. The healing cap on top of the implant is sometimes color coded so maybe that's what you're seeing. If you're concerned, I recommend seeing your dentist.Good luck!
