@Auste Liegute: I’m not sure what you mean by “if the tooth is not moving”… I assume you’re saying it’s not a simple extraction. Root anatomy and ease of exodontia is a part of the treatment planning teeth for IR vs. apico or simple extraction. So, you need to have this figured out in advance by making sure you have confluent roots as opposed to divergent roots. Also, if necessary, you can use mild to moderate use of elevators to help loosen the tooth without too much damage to the root surface.
Lastly, if you get pus drainage, you can use a suction inside the socket and pull out all the pus, curette the socket mildly before preimplantation. If you can have direct suction inside the socket it won’t take you long to remove all pus. Good luck! 🙂
