Lump in mouth, near gum, increase in pain, had a root canal. Why does it feel squishy?
Patient: I have a small lump under the bottom of my gum on the inside of my mouth which when I wake up in the morning is about the size of a pin head , throughout the day it increases to about the size of half a pea , its not visable and can only feel it with my tongue.The lump is not really there when i wake up in the morning but grows throughout the day then shrinks again, not painless.Had root canal done yesterday and the pain my tooth has gone but the lump is still there - will this disappear over time or will it require any treatment - I have no idea how long it could have been there but the fact that it shrinks and grows throughout the day is a worry - any ideas what else I can do now I have had the root canal treatment - it feels squishy almost like a gland then sometimes it feels hard and is right below the gumline - should I be worried about this ? Doctor: Hi user thanks for posting your query.  As per your histroy the swelling or lump may be because of perapical lesion if the lump is buccally(that is inner side of cheek) and if it below the tongue .it would be some small salivary  gland or duct infection.anyway to rule out this you may need to take x ray for rct tooth and if it gland problem =saliogram.but with your qurey it most likely sounds like perapical lesion so may have to undergo re root canal and if requrid endoperio surgery or extraction depends on lesion on x ray and tooth present condition.
