The thing about mouth pain from a dental emergency is that you can't go to a doctor to get it fixed. Sure a doctor in the emergency room can prescribe painkillers but they can't do anything to fix the problem.
What you need is an emergency dentist who can make the pain go away permanently so you can get some sleep and get back to work. An emergency dentist can take care of everything from tooth ache, swollen face, excessive bleeding due to having a tooth removed.
One of the harshest realities of extreme dental pain is that it usually occurs, or climaxes in the middle of the night, exactly when your dentist does not have hours.
The sad fact is that if you live in small town, the chances of find an all night emergency dentist is slim. Of course, if your city is small enough you might even know your dentist personally and you might be able to squeeze a favor out of him or her.
If you live in a large city, your chances of finding an all-night emergency dentist is far better, but that still means that you have to track one down.
Don't be under any illusions that having an emergency dental procedure is going to be cheap. Most dentists didn't get into the profession to work all night for a pittance. You'll pay a premium for the right to have your problems solved. Often this extra expense comes in the form of an after hours fee that is tacked on top of your usual fee.
Worst of all, this is rarely covered by your health insurance, but if you really are having a dental emergency then you are probably in so much pain that you couldn't care less how much the procedure actually costs.
The other main reason that people need emergency dental surgery can be observed at any decent hockey game. Sports injuries are the major instance when emergency dental surgery is required. Due to the severe nature of many sports related dental emergencies the patient often needs work done right away.
Many sports injuries lead to heavy bleeding and damage to the over-all mouth area that may require work by both a dentist and a doctor. This is unfortunate but there is a slim chance that a fatality can occur if there is severe damage to the mouth. Often this occurs if the patient swallows too much of their own blood.
If you do have a dental emergency from an athletic injury, consult a doctor first to make sure that you contact a doctor first to make sure there is no chance that you could die from the injury.
