While it may seem more efficient and cost effective to have a tooth pulled instead of going through a root canal, this is actually not the case.
Missing teeth need to be replaced because leaving a gap in your teeth can have serious consequences for your long term dental health. The other teeth in your mouth will shift out of place over time, causing misalignment and pain.
Replacing missing teeth can be inconvenient and expensive. Dentures can be difficult to fit properly, and dental implants involve major surgery and costs. Dental bridges require the removal of enamel from the surrounding teeth, which can lead to other dental problems down the road.
All of this can be avoided by undergoing a root canal rather than extracting the tooth.
