Our First Dental Visit

Two weeks ago John was walking around the living room and lost his footing. He fell face first into the hardwood floors and was unable to catch himself or even get his hands down. Basically...he ate the wood.
There were tears and snuggling, but no blood. I noticed the his tooth (top tooth one off from the front) looked like it had been pushed back up into his gums. I had hoped that he would be OK and had been keeping an eye on it. The tooth appeared to be yellow and a bit sensitive when brushed. I decided to take him to see a pediatric dentist last week.
It turns out that not only did his tooth go back up into his gums, it also broke. The tooth basically cracked all the way across and the front tooth has a fracture. I was concerned that the tooth died, but the dentist feel confident that it is still alive. We go back in three months and if there is no change then we will do an x-ray. If the tooth dies then we will have to have it pulled.
I didn't even realize that it was cracked and feel so bad about waiting to take him to see the dentist.
