Your mouth may be sore for a few days after root canal surgery. During this time, continue to restrict your diet to soft foods, abstain from smoking, and drinking. Once your root canal surgery is complete, you can care for your teeth by following a rigorous oral hygiene regimen that involves twice-daily cleaning, daily flossing, and the use of mouthwash.
Occasionally, a root canal-treated tooth can darken a few colors. This is becoming less common, so if there is any discoloration, you can see your dentist, who will be able to provide a remedy that will restore the tooth to a more natural color that matches the rest of your teeth.
