<human>: went to the dentist and had a silver tooth filling replaced by white went back 3 times and still didnt have the tooth right finally got it to where i can bite down but now noticing a month later I have a huge hard knot on the side of my gum doesnt really hurt but its there and then did a cold test on my teeth on gums both sides could not feel it but could feel the cold test on front teeth.
<bot>: Hi. Thanks for the query. The lump can be due to causes like a Periapical cyst. It represents as a painless lump on the gum. If it is bony hard it can be a bony torus. So my suggestion is to consult an Oral Physician and get evaluated. An x-ray can be done for confirmation. If it is a cyst then it has to be removed bye nucleation procedure. If it is a bony torus then surgical removal can be done. Hope this helps. Regards.
