Root canal treatment involved removing nerve and tissue from the inside of an infected tooth. It is important to know how to care for the tooth after having treatment, to ensure that the tooth heals as best as it can and returns to normal functioning. 

Straight after your root canal treatment, your mouth will continue to stay numb for a few hours while the anesthetic wears off. During this time it is important to not eat anything too tough, hard, sticky, or hot. Slippery, cold, smooth food and drink is best to consume in the hours after the treatment, so that you ensure that you do not injure yourself. It is also best to try and avoid chewing on the side of the mouth that the root canal procedure was done in. 

A root canal treatment can take up to 2-3 appointments, so it is important to take care of the tooth in between appointments with the dentist. Temporary fillings are used in between appointments, although they are not made like normal fillings and cannot sustain extreme pressure or tension, so it is best to avoid very hard or crunchy foods to ensure that no damage is done to the filling. 

It is normal for your tooth to feel a little tender or sore for a few days after the root canal appointments, your dentist will speak with you about pain management in a consultation before the root canal. Oral hygiene is especially important to keep up with between root canal appointments, and it is best to avoid foods that have a high sugar content to prevent further decay in the tooth.
