I Recently Broke My Upper Jaw In April Of This

I recently broke my upper jaw in April of this year. I had surgery to place the arch bar on my upper jaw and had it on for 6 weeks. I also had 3 root canals done to my upper, front teeth due to the trauma from the injury and am due for braces within the next couple of werks to adjust my bite. I am a very active person and it seems that especially after a tough workout, my upper teeth throb and throb. Randomly throughout the day, my teeth will begin to throb. It's not painful but more an irritant. Is this throbbing normal nearly 5 months out from injury?
