It is all too common to see fracture lines in teeth that formerly had amalgam fillings (the metal expands, pushing outward on the enamel holding it in place like a wedge). Your dentist was likely trying to preserve the tooth by placing a composite (white filling) inside to kind of hold things together. An x-ray doesn't really show a crack and often you can't even see it just by looking at the tooth. I usually rely on symptoms and some tests that I perform when the patient comes in. Are you currently experiencing pain? Does the pain happen most when chewing something crunchy or chewy? These are questions that may have lead your original dentist to believe that you had cracked tooth syndrome.
If the crack does not extend too deeply into the tooth, I would prepare the tooth for a crown (or preferably something called an Onlay, which is more conservative). During this preparation, the dentist has the ability to see into the tooth and sometimes the crack is openly visible. If not, they may opt to place a temporary crown over the tooth and see if you notice any improvement in symptoms. If symptoms do not resolve in a week or two, it is likely that the tooth will need a root canal and then the final crown.
One thing that contributes to the formation of fractures and the symptoms associated with them is nighttime clenching and grinding. You may not even be aware of it, but certain times or all through the night you can be exerting extreme pressure on your teeth and this force can be highly destructive and also exacerbate any existing problems. A nightguard made by your dentist can be used to cushion your tooth while you sleep and also will help to determine if the problem is caused by clenching at night.
Either way, don't wait to see your doctor and resolve this problem because a fractured tooth does not resolve on it's own.
