hello christina and welcome to HCM,
Its good, that you managed an appointment with the dentist
. But be careful to visit him surely on the arranged time as teeth aches use to spread till the face above and to the neck below.
Don't worry, as the treatment comes to start, you will start getting relief. broken tooth is the main cause of it or if the tooth is out of the jaw, then might be some broken pieces are creating the pain.
So, don't delay and get the treatment.
