<s>[INST] Everytime a patient has pain in tooth etc, we would find him applying pressure in that particular area with his fingers & This pressure application helps in relieving the pain a bit.So whats the science behind this pressure application and pain relief. [/INST] Hello, thank you for consulting with Chat Doctor. There are two conditions in which patient feel relief after applying pressure, First is periodontal abscess, means abscess in gums, in it when pressure is applied on the abscess, the content of abscess leach out from area between gums and tooth, so pain decreases. Second conditions are vertical fractured tooth, so when pressure is applied tooth divides in two parts and pain get relives because of space is created for infection to release. Hope it will help you. </s>
