What is this lump? Could it be because of my severe grinding & clenching? Would prolonged grinding cause healing issues? (Photo)

For unique cases where a variety of modalities could be used to treat the condition, I would suggest an in-person or virtual consultation to develop a custom and effective treatment plan. It is difficult to precisely define the best option without collecting the same information. I suggest reaching out to an expert for a consultation with surgical and non-surgical methods to get a comprehensive option. Best, Dr. Emer.

Week three is still very early, especially when it comes to healing after surgery, so it could still be swelling. I would recommend to just be patient and revisit that after a few more weeks.
