Slight receding gums after Apicoectomy. Is it fixable or do I have to get new crowns? (Photo)

To give an accurate answer more tests are required, however from what can be seen in the photo, there is gingival inflammation and recession. First, we would have to determine the cause, it may be that in the apicoectomy procedure the surgical approach has been in that area and now is healing, it may also be a sign that there is periodontal disease, so first we would have to determine the cause to decide whether or not new veneers are necessary
