Hi. I had my last molar tooth removed approximately 7 weeks ago. The healing seemed to be going fine until 2 days ago. I was eating some food and it felt like I had eaten something and couldn't get it out, so I just left it. For the first time I used electric tooth brush and gave the extraction area a good clean. Since then it has formed a flesh coloured squidgy lump that has covered the entire extraction area between wisdom tooth and 2nd last molar. It is flesh in colour with a slight yellowish twinge about it and quite squidgy. Around the same time that it developed I have now got a large ulcer in my cheek beside upper teeth and a few white spots that are painless. The lump is totally painless by the way. Would this be a reaction to the heavy toothbrushing, or food lodged in hole? Just seems strange as I don't know how it could just appear in a couple of days when it was still a hole? Does it sound like cancer?
