Is there any way to use a side profile picture and make a morph face out of it?
No, the morph engine is setup for 0 degree face.
You can pretty much use up to a 45 degree face angle with decent results.
And is there anyway to import your own custom made teeth for morph faces?
Yes, you can import your own morph teeth, even a diffuse image for the teeth.
