3 yr old took a fall and upper 3 front teeth knocked up into his gum 7 months later an abscess formed on gum dentist did root canal but another abscess has formed would you suggest removal of teeth?

Given the recurring abscess and the fact that the teeth have already undergone a root canal, it may be advisable to consider removal of the affected teeth. Persistent infections can lead to complications and may affect the surrounding teeth and gums. Consulting with a pediatric dentist or an oral surgeon would provide the best course of action tailored to the child's specific situation.
