Is Therapy Appropriate Now?

I am seeing an 8 year old boy for correction of a frontal lisp.

The young man has good placement and what I consider to be good production of the /s/ in words and sentences, and conversation.

His mother is concerned that his /s/ is not "clear" all of the time.

Here is the catch.

They boy has had both of his upper canine teeth extracted, therefore air is escaping laterally.

Should I continue working with him, trying to occlude the gaps with the sides of his tongue or would you recommend waiting until his teeth come in?
