This is a most common misconception that the removal of any tooth (most commonly upper ones) will damage the eyesight, but No, there is no connection in between eye and teeth. The nerves that enter teeth and eyes are different and has no inter connection. When people suffer from a toothache, the feeling of pain on the nerves of the tooth may be transmitted to other facial nerves, so it can cause swelling and discomfort of the cheek or eyes. However the removal of any tooth does not cause any damage to these organs.
