If done correctly and minimally, lasering gingival tissue should not cause recession.  In fact, the gum tissue generally wants to come back down to it's originally level, and you actually need to brush the tissue to keep it from coming back.  Periodontist can be caused from many other reasons.  Periodontist is classified by attachment loss.  Generally this is caused by accumulation of bacteria and biofilm. You may need to have a deep cleaning, and have the temporaries placed correctly to allow the tissues to heal.  The temporaries may be impinging on biological width, which can cause recession.  It might not be a bad idea to get a second opinion.
