The specific reason may be due to local oral reasons, the hygiene conditions in the mouth may not be good, there are more food residues, so there is more plaque and calculus on the teeth, there will be a lot of bacteria breeding on the teeth and will invade the gums to produce gum inflammation, which will lead to itching or bleeding. Itchy and swollen gums can be further aggravated when hormones increase. Chronic systemic diseases can also cause itchy gums.
