If gingivitis is not treated the inflammation will work its way down towards the foundations of the tooth causing a “periodontal pocket”. Again, within the confines of the pocket, the conditions are such that the bacteria can have a right old party, and cause more damage.
Gum disease can break down the support (bone) structures of the teeth so that eventually, they will become loose. The problem is that until it gets quite severe, the person often has no symptoms. Sadly, the damage to the support structures of the teeth is irreversible. The good news is that if gum disease is caught in time, its progression can be halted and improved upon, and that is the key.
To stop gum disease from progressing, your dentist may advise periodontal therapy or deep cleaning. This gets rid of the bacteria in the pocket and provides the necessary conditions for healing to occur.
