Of course, it is possible to speak after tooth extraction, especially for the extraction of general teeth in clinical practice, the trauma of tooth extraction is not particularly large, and there is no direct relationship between the extraction wound and speaking, so you can speak immediately after tooth extraction. However, in the case of clinically more traumatic extractions, such as the extraction of buried wisdom teeth, the extraction process involves incision, flap, debridement, root division, suturing and other operations that are more traumatic, and there will be significant facial swelling after the extraction. This is not directly related to the tooth extraction, but it is just a side effect of swelling and reduction of speech due to the relatively large trauma.
