Gingivitis refers to an inflammation of the gum tissues, commonly caused by not brushing teeth in time after eating, accumulation of food residues or dental plaque around the teeth, which over time forms tartar due to the calcification by saliva. This long-term irritation to the gum tissue leads to bleeding gums, including bleeding while eating or brushing teeth. It is necessary to get a timely dental cleaning, otherwise it can lead to periodontitis or even result in loose teeth, and potentially tooth loss. Therefore, the harm caused by gingivitis is significant. Once gingivitis occurs, it requires timely dental cleaning to remove tartar and other irritating factors to alleviate symptoms of gum bleeding, allowing the gums to return to a normal, healthy state.
