Periodontics

Periodontal disease happens when the plaque becomes more aggressive and the gums get  irreversible inflamed. Poor Oral Hygiene will make it progress faster,  
It is always associated with tartar deposits built above and under the gum level, gum pocketing, bone loss.
The treatment is complex and consist in regular deep clean every 3 months (or even more often),  small surgical procedures to the bone and gum.
