1, in general, a few days after the sealing of the root canal treatment, the tooth may be a bit uncomfortable, as children will feel the feeling of swelling there. This is a normal post-X reaction, so it is normal to avoid eating hard food and to brush the teeth. 2. Most children will get through these days easily with parental support and by distracting them from the discomfort. So there is no need to worry too much. 3, but if the reaction is very big, the child is very uncomfortable, jumping up and down, affecting your family’s life; or if there is a significant swelling of the gums, you can go directly to the hospital to register for emergency treatment. 4.Bring your previous medical records with you when you visit the hospital. Our general treatment may include: removing the medication to suspend discomfort and making a follow-up appointment for further treatment. Appropriate medication may also be recommended as an adjunct to treatment.
