While there is a lot of pressure during the extraction of a tooth there should be no pain during the procedure. The painfulness of after extraction of any tooth depends on a few factors such as; age, tooth, location of tooth, angle of the tooth, how far broken down the tooth is, etc.
Age plays the same role as when we worry about elderly people falling and breaking a bone. As we get older our bones become more stiff. When a tooth is extracted the jaw bone has to be flexible around the roots in order for it to come out. This gets happens less when we are older. If the bone is stiffer then the tooth is going to require more force and thought to remove. This means the post-operative discomfort may be more.
The type tooth it is does make things more complicated and the amount of discomfort felt afterward could be influenced on how the tooth is extracted. A molar usually has between 2 or 3 roots (sometimes more). The jaw bone around these roots is going to have to be more flexible unless the tooth is sectioned into the individual roots and then removed. Less flexing of the jaw bone usually means less discomfort after the extraction.
If the tooth hard to get to then it could mean that there is more force applied in certain areas instead of spreading it around. This may have more discomfort afterward. Hope this helps.
My best to you!
