I had tooth extracted 12 days ago and noticed white little bumps on gum above extraction. when i talk or eat i can feel them? what are they? normal?

Bone defects: Surgical removal of the tooth can create an alveolar bone defects. Tooth extraction is a traumatic procedure initiating a complex cascade of biochemical and histologic events that inevitably lead to a reduction of alveolar bone, soft tissue and bone defects (exostosis). These defects will be addressed before future teeth emplacement. See your dentist for post-op examination.

White bumps: Can't tell without exam/. Probably not problematic, but see the Dentist or specialist Oral Surgeon for a follow-up exam. The cost is included in yo0ur surgical fee.
