Luckily, root canals are not as invasive and painful as many people believe they are. Simply put, root canals remove any bacteria that has been able to grow inside of your tooth and then add a dental crown so that you are still able to chew like normal. Once this procedure is done, you should be able to eat, brush, and floss normally.
Overall, root canals can be managed with simple pain relievers while they are healing. You will want to make sure that you are not chewing with your teeth until the allotted time your dentist has suggested ends. Otherwise, your new crown should not feel all that different from before the pain started.
You will want to make sure you treat the crown with care, but it should require the same amount of maintenance that every other tooth in your mouth requires. If you find that your new crown is causing issues that your other teeth do not create, then you should schedule a follow-up appointment to have it looked at.
