*3-6個月是來自Merck的建議,6-9個月則是來自《Veterinary Periodontology》建議。


貓咪痛到吃不下怎麼辦?

可短期使用 Buprenorphine 止痛藥,並暫時改餵罐頭或軟食,待洗牙與牙周治療穩定後再恢復乾飼料。

一拔了之後就沒牙齒吃東西怎麼辦?

幼年增生性口炎的拔牙僅限嚴重牙周病的牙齒(選擇性拔除有問題的),並非全口拔。而有問題的牙齒,基本上也不會去使用它。

刷牙刷到流血還要刷嗎?

輕觸即出血代表發炎嚴重,更需要刷牙;如果真的出血量較多,或是有明顯疼痛,則可改用紗布+漱口水清潔表面,或使用軟細毛的牙刷清潔,等2–3 週後組織較穩定再回原本牙刷。
