When Scaling and Polishing are not done routinely, the gums get infected and tend to bleed. The infection causes a bad odour in the mouth, leading to what is commonly called "Bad Breath". Cases with bleeding gums and bad mouth smell are easily treatable. The cause of the problem is the Bacteria. Once we remove the Bacteria the problem settles down. Scaling is done and if needed Gum curettage is done. In advanced cases, gum surgery may also be needed. Some times a bone graft may be needed to repalce the bone that has been lost.
