Dental bridge pain bleeding after cleaning

It is unlikely that a rough cleaning would cause sensitivity or pain under a bridge for that period of time.  I would recommend that you call your dentist and let them evaluate it.  Until then, use warm salt water rinses a couple of times per day to help with healing of the gingival tissues.  Best of luck.  

Hi there!Sometimes during a cleaning, tissue can get hurt while trying to remove all the bacteria - especially around crowns and bridges where there are more places for plaque to accumulate. Salt water rinses can help heal small wounds in the mouth, but it would be best to have it checked out by your dentist to make sure its nothing more than that!

It's unlikely that a rough cleaning would cause your symptoms. It sounds like you may have something lodged underneath the bridge.  You did say you floss daily - it might be helpful to sweep under the fake tooth of the bridge with superfloss which has a thicker, fuzzy segment to it.  This could help dislodge whatever might be there.  It would be advised to make an appointment to have your dentist take a look at what may be going on in that area. Best of luck!!
