Probably: After a year you should be fine. But that's not a guarantee... I've seen teeth become non-vital ten years after being traumatized. Keep them clean and visit your dentist regularly.

Highly unlikely: If after the injury the follow up pulp tests were used properly, injury to the pulp is highly unlikely. If concerned, see your dentist for consultation.

Maybe: Anytime there is trauma to teeth, that increases the chance of needing a root canal in the future. There is nothing you can do to prevent it.

Probably: It's rare, but sometimes teeth that have been traumatized can become non- vital with the passage of time. Ask your Dentist to keep them under observation.
