Is it okay to brush my teeth still while having an abcessed tooth?

Always: Do not skip cleaning do to clean a zit or let it go. The mouth needs thorough cleaning daily. Seek a dentist.

Yes.: Logical question should be, what does the abscessed tooth have to do with the remainder of the teeth in your mouth? Of course you should brush your other teeth. In actuality, you only need to brush the teeth that you would like to continue to keep in your mouth, which should be all of them.

It would help: Even though it may hurt when you touch the abscess tooth, keeping it clean would help to drain the infection and thus providing short relief. You should schedule with your dentist to eliminate the cause of the abscessed tooth (root canal and fix occlusion) to prevent it from coming back and keep the destruction of surrounding tissue to be minimal.
