This morning in family video call, my first granddaughter opened her mouth and showed me the vacancy of her upper front tooth, right in the middle.  Oh my goodness, she is now six and four months, and she has begun changing teeth, ready to get her permanent teeth to replace the deciduous ones.

My little girl, may you smoothly pass the interval of teeth changing, and after that, wish you a mouthful of white, neat, and healthy teeth!
