If I were to plant a tree for each time I have been asked this question, “Does tooth extraction affect eyesight?”, maybe there would be a medium-sized forest around my clinic.
This is purely a myth, probably arising from the close relationship between the teeth and the eyes. However, both structures have different nerves and blood supply. The proximity has no direct relation, neither in their functions nor in their dysfunction.
Sometimes, referred pain and common issues like sinusitis or numbness above the teeth during local anesthesia for extraction may be misinterpreted as related effects due to a tooth problem. If managed systematically, both problems can be managed easily.
So, the final verdict is NO, tooth extraction does not affect eyesight in any case.
But all dentists should keep in mind that there is always a possibilty of spread of local anaestheic solution to orbital structures in case of PSA , IANB , greater palatine blocks if and when improper injection techniques are used. These complications can be mostly transient and rarely permanent . So, we need to be thorough with identifying the anatomical landmarks while administering LA.
This myth is so common and many patients deny extraction of upper teeth due to this fear but all in all myths remain myths and it is indeed very important to burst these
