These pictures will help you understand and diagnose the stage of gum disease you are suffering from:
Gingivitis is an inflammation that is limited to the gums. In most cases, gingivitis is caused by the accumulation of plaque and poor oral hygiene. But there are situations where gingivitis appears due to hormonal changes (eg pregnancy) or taking certain medications (dilantin or adalat). If gingivitis is not treated it can reach all of the periodontium and cause periodontitis, a more severe gum disease explained next.
Periodontitis is an infection not only reached the gums on the surface, but also to the entire periodontal tissue. A dentist can detect the presence of periodontal pockets (deep spaces created between the tooth and the gums), bone loss (the bone level around teeth decreases), or tooth mobility (moving teeth). This is a serious condition that must be addressed quickly to avoid losing teeth. Periodontitis can also be linked to other diseases of the body, such as diabetes or certain heart diseases.
Gingival Recession (or receding gums) refers to a loss of gum tissue around the teeth that leads to exposure of roots. This condition is mainly caused by rough brushing which, after years, affects the strength and firmness of the gums. This loosening can cause tooth sensitivity, and sometimes an aesthetic problem if gingival recession can be found on the front teeth.
