Wa'alaikummussalam! Gusi berdarah ni mmg annoying kan, especially when brushing teeth, a few of us mums ada experience ni, usually sebab tartar buildup or hormonal changes (especially kalau pregnant or post-partum). Tapi honestly kena check dengan dentist sebab bisa jadi early sign of gum disease or deficiency, so jangan delay ye; better safe than sorry! In the meantime, try using a soft toothbrush, brush gently jangan force, and some of my mum friends swear by oral rinse or upping vitamin C intake, tapi appointment dengan dentist is really the best move.
