Oral Health & Hygiene of 19 months old toddler

Mummies, how do you all introduce brushing to your child? My girl hates cleaning mouth (she won't open for checks, bites when I use oral wipes or cloth to clean her teeth & gums) I have been trying to introduce brushing since 2-3 months back but unsuccessful. She likes to put fingers into her mouth, has bad breath and only drinks plain water when she is super thristy. I am having alot of difficulties keeping her clean and bringing her to the dentist will be my last resort (don't think she will open her mouth at all 😅) My hubby & I have led by examples by showing her how we brush our teeth, sing songs to her, gave her toothbrush (she will just hold but never put in mouth)#pleasehelp #advicepls Any suggestions?
