Sometimes deep cavities in your teeth can cause severe pain. This indicates that the nerve of your tooth is infected which requires RCT.
2) Gingival Swelling
A tiny pimple or a large swelling on your gums can be due to an infected tooth, which is treated by RCT.
3) Chronic tooth wear
Chronic grinding can lead to the wearing of layers of the tooth. Subsequently exposing its nerve, leads to severe sensitivity which requires an RCT.
Long-standing history of trauma to the tooth can cause discolouration, which can be rectified with an RCT.
A fractured tooth in which the nerve of the tooth is involved requires RCT.
