i had dental work done on my front teeth think i got crowns. One of the teeth i had to go back to be seen for maybe twice after the work was done due to my mouth still hurting. Now my nose fellt funny but I thought it would wear off its been over 2 years and my nose still has a weird sensation that i only got when this procedure was done. So recently i went back to the dentist and told the dentis about this weird sensation with my nose every since they worked on my teeth. She asked me to open my mouth and she said oh i see you have a small hole somewher in my mouth in the area they did and its probably air seeping in causing the weird sensation. have you ever heard of this?
