Hi- My 5 year old daughter had a baby root canal yesterday. Not removing the nerve just cleaning and packing. She has been on antibiotics (allergic to amoxicillin so the gave her something else) due to a small abscess for the past week prior to appointment. The dentist said he is trying to save the tooth as she will need it for another 5 years or so. There was a lot of drainage per the dentist. My daughter did not even flinch during procedure and when I got home I gave her motrin and was told to finish the remainder of the 2nd bottle of antibiotics by the dentist. However, she woke up 2 times during the night and this morning moody as could be. I felt her cheeks were a little warm and took temp. 100 at that time. Is this something that I should be concerned about and get her to an ER or??? Thank you...
HELLO AND WELCOME, AS per the description, the abscess has developed due to spread of decay into periapical area. Your dentist is removing the decay and the infected pulp thereby enhancing Chat Doctor.  During such procedures pain, swelling and fever are associated symptoms. Moodyness may be due to heavy antibiotics taken by your child so nothing to be panic. Avoid intake of hot/spicy foods. Take plenty of water and fluid to keep your baby nourished. If symptoms persists, please do visit a physician too. Hope this helps
