to start i dont have wisdom teeth. i had a crown on one of my back molars and it fell off a year ago. iv had no problems so far. but 2 weeks ago i noticed skin or gum tissue in the hole of whats left of the tooth. at first i thought nothing of it but it has rapidly grow in these 2 weeks. the tissue now fills the entire hole in my tooth and seems to still be growing. it bleeds everytime i brush my teeth and occasionally through the day, but its not painful anywhere. it is a little sensative but isnt causing pain. do u know what it could be and what i should do? i am unable to go to a dentist becausse i cant afford it.
