Could I have an air pocket under a dental implant?

Hi:Sorry to hear about your pain.  It's best to take a cat scan of the implant for further evaluation.Best,Dr. Maddahi

Sorry to hear you are having pain with your implant. I am assuming that you have a bridge that is screwed to your implant. If you have had pain before they were taken out and no evidence of infection has been noted it may mean that your bite may be off. I would have the dentist check your bite. It is not normal to have pain with your implant and perhaps you should see your restorative dentist or get a second opinion.
All the best to you.
