Most Common Signs of Gum Disease:

Redness, Swelling, and painful gums

Bleeding during chewing, flossing and brushing

Bad breath

Gum recession 

Pus pockets

Loose teeth

Without gum recession, healthy pockets range from 1mm to 3mm.  Pockets of 4mm are in the danger zone. Pockets above 5mm can be treated with a non-surgical intervention (Arestin or Perio Trays) or surgery may be recommended.
