Hello, about a month ago something was up with the gap between the last tooth and the one in front of it. it felt like as if i had something hard stuck in between. So i tried picking at it with a toothpick and nothing seemed to happen, so then i tried floss...and still it felt like something was stuck in between. and finally i took the  dentist pick and started to pick at it, i guess i did it too rough because a part of my tooth cracked off. Now i am left with a cavity that hurts when i try cleaning it with a tiny brush or pick. It also gives off a bad cavity smell. I dont know what to do, I know i need to get it examined asap but i am afraid that the cavity is so deep that it hit a nerve and i may resulting in a root canal.
Hello, thank you for consulting with Chat Doctor. This cavity means that there is some infection inside the tooth. It is not necessary that the infection has spread to the nerves of the tooth, to get it confirmed you have to go for an x-ray. After an x-ray only it will be decided. Hope it will help you.
