How does tooth removal (tooth extraction) work?

There are two types of extractions- a simple extraction and a surgical extraction. The type of extraction that is necessary depends on each individual's case. A simple extraction is when the teeth is easy to reach and can be easily removed. A surgical extraction is needed when more of the tooth is below the gum or bone line and tougher to remove. The tooth must be cut out. Sometimes this can result in more discomfort. Your dentist will begin by numbing the area, unless you request not to do so.

Discuss with your dentist the type of tooth extraction that is needed and all post-extraction care.
Tooth removal (or, extraction) works either 'simply' or 'surgically.' Simple extractions are typically those teeth that are quite loose (held in soft tissue or minimal amount of bone) remember the top part of the tooth could be very loose from fracture or decay, but that doesn't necessarily mean the whole tooth is loose. The root remains to be taken out also! The term surgical extraction is usually for those teeth that may require some retraction (but not necessarily removal) of gum and/or minimal bone tissue for visibility and access for removal. Sometimes due to angulation of the tooth (for ex: wisdom tooth), the dentist may intentionally break or 'section' the tooth for easier removal. As with most dental procedures, it isn't always necessary to see a specialist (in this case oral surgeon.) Ask your provider their level of confidence and expertise in the type of extractions you may need. Your provider may even offer sedation dentistry for a more comfortable experience for you.

Tooth removal isn't primarily about the strength needed to 'pull' teeth, but the skill in applying simple physics in retrieving the tooth from the socket.
There are two different types of tooth extractions that can be used to remove teeth. The first is a simple extraction. This type of extraction is used when the tooth is relatively easy to get to. Your dentist will simply numb the area surrounding your tooth, and then use a pair of forceps to wiggle it loose from your jaw. If the tooth that needs to be removed is harder to get to, for example underneath your gums, then you will need a surgical extraction, which is generally performed by a specially trained oral surgeon. Once again, the area surrounding your tooth will be numbed, or you will be sedated before the procedure begins. The surgeon will then cut your gums in order to gain better access to the tooth. You may experience some pain and swelling following a surgical extraction, and so it isn’t uncommon for your surgeon to prescribe a painkiller.
