Just had 2 dental implants done. was told that the size of the healing cap may need to be replaced at the next 2 week post-op visit. more surgery?

Maybe not...: If your current healing cap is exposed, than your dentist or surgeon may be placing a bigger healing cap to allow the tissue around the head of the implant to heal in such a way to create a better esthetic result. The other reason is that the length of the healing cap needs to be longer to avoid the need for a second surgery. To get the specific answer, just ask your dentist.

Probably not: Just a placement of either a taller and/or wider healing cap. Glad you decided for the surgery. I'm sure your pre-surgical concerns were for naught.

Typically not: Only reason for changing size of healing abutment is to increase it to prevent tissue overgrowing the top or reduce it to allow more comfort for you if height not needed. If a width change, then it is for "emergence profile" , or guiding the tissue contours for a better final result. Good that your surgeon is thinking this way for you. We normally provisionalize to achieve this. Good Luck.

No: Not necessarily, changing healing cups does not necessarily mean surgery, most of the time can be done ecen without anesthesia
