Why Is There a Bump on Your Gum After a Root Canal?
If you have had a tooth abscess, then you're likely to start feeling a lot better soon after having a root canal done on the tooth. This procedure removes the infection and cleans out the tooth.
However, you may be a bit worried if you look in your mouth the next day and see a lump on your gum under or above the treated tooth. The lump feels a bit sore and tender when you touch it.
