I have developed a hard (like bone) painless lump on inside of upper gum between the last 2 molars. It is about 1cm below the teeth and the size of a large pea. The 2nd from last molar had RCT and a crown fitted 20 years ago.

I have had several bouts of pain in the face on this side and area over the last year which my gp has put down to sinusitus, now Im not so sure.

I have been to see my dentist who looked at an xray taken on a previous visit and commented that the crown there was done a long time ago and there was some unusual white lines on the xray. He says he may have to take off the crown and redo the RCT. He gave me some antibiotics.

I am very worried that this may be mouth cancer, please advise.

Also I have seen my GP several times about a whitish spot on the back wall of my throat. I have managed to get some whitish stuff out of it, but it always comes back. My GP says it is probably a retention cyst.

My dad has just been diagnosed with Non Hodgkins cancer and Im freaking - Am i worrying unneccesarily about these two symptoms?

Hello Helen

Your dentist has had a look at the lump and obviously didn't think it was a cancer. Sometimes a chronic infection from a non-vital tooth can give rise to a boney hard swelling; the increased density could appear on an x-ray as a white opacity. Your dentist is probably thinking the same when he said that he might have to redo the RCT.

Most people would not have looked at the back wall of their throat. A whitish spot could be food debris, mucous, etc . It could be a retention cyst if you can express something and it recurs.. Since it has been thee some time and not grown, it is unlikely to be a cancer.

So the bottom line is that it is unlikely that you have a mouth cancer. Be vigilant but not paranoid. Hope that helps.

Best wishes

The lump didnt seem so pronounced after the antibiotics and this week, after another flair up of pain I have had the RCT done again and a large filling fitted.

The thing is I have noticed the lump again since - is this okay, could it be from the injection or from the chronic infection.

Is this something I shouldnt worry about seeing as it is now 18 months since i first queried it and the lump seemed to die down, but now up again after work carried out (but no bigger).

I do suffer from Health anxiety but have kept it in check for the last 6 months !
