It is estimated that 9-17 percent of children between the ages of three and 11 years have gingivitis.
These major oral health problems are plaque, tartar, gingivitis, periodontitis, and tooth decay.
Trench mouth, also called Vincent's disease, is a suddenly developing (acute) complication of gingivitis.
Gingivitis can be aggravated by hormones and may temporarily worsen during puberty and pregnancy.
This early stage of the disease is called gingivitis.
