Teaching our kids good oral hygiene practices could be a twice-daily battle. But it's a fight worth having. It is very important to make brushing and flossing a part of their morning and nightly routines. You could try making brushing and flossing a fun and engaging routine by turning it to a game or play her favorite song while brushing or say a story that you are chasing and killing the sugar bugs on her teeth. At the end you could hand the brush to your child and ask them to complete the chase. Don't forget to praise her afterward for her sparkly teeth.
Hope this helps!
