Endodontist advice

[Eros]

I've had a mild dull ache in my filled molar upper right 7 for three months. Originally very occasionally but now two or three times a day - still very mild.

I've had my dentist check it a couple of times including xrays and various tests and he can find nothing wrong with it. My concern is the roots may have Pulpitis though my dentist says there is no sign of that. Tooth does not react to cold or hot or pressure. He thinks it might relate to receding gums but at the moment to 'wait and see'.

My question is would an endodontist with specialist equipment be any more likely to spot the problem at this stage?

Thanks
