Gum enlargement in children is generally rare, and individually there are different causes, for example, some enlargement is medicated, some children have other diseases that require long-term medication, and some medications can cause gum enlargement. If this is the cause, it may be necessary to coordinate with the internist to stop the medication or to find alternative medications to alternate. If it is due to other causes, such as localized tartar and other irritants, it may subside naturally by removing the local irritants and maintaining good oral hygiene. There is another common type of gingival hyperplasia which is caused by gum caries, there is always food embedded in the caries cavity, which keeps stimulating the gum next to it, and the gum will form hyperplastic polyp to fill in the caries cavity, then don’t panic, decay the caries area, that is, clean and remove the hyperplastic gum. If some hyperplasia is more serious, special gingivectomy may be needed to remove the hyperplastic gum, and then do a good job of oral hygiene maintenance can be done.
