Can you tell me where to aim when infiltrating?

Can you tell me where to aim when infiltrating? For example, when infiltrating the mandibular premolars, do you aim for the apex of the root and then inject, or do I want the needle to enter the mental foramen before injecting? For the mandibular molars, do I hit bone and inject into the bone, or after hitting the bone, do I pull back a drop and then inject?

I put the needle 3mm-6mm deep into the tissue depending on what tooth I’m anesthetizing. If I contact bone, I will typically pull out <1mm and deposit. I don't insert the needle into the mental foramen when I administer a mental injection, I'm typically just superior to it and deposit, I then follow with extra oral pressure to force the anesthetic into the foramen.

I didn’t realize, I didn’t mention where to aim, I aim towards the height of the vestibule superior to the tooth I am infiltrating.
