According to the British Dental Association, there are deciduous molars, all of which eventually fall out by around age 12, and permanent molars, which do not necessarily fall out. All the deciduous molars appear by the time a child is around 2 1/2 years old.
Mascara: Get yourself a pre-wash stain fighter like Shout and apply to the stain using the brush that comes with the pre-wash. Let it sit for about 10-15 minutes, then rinse with hot water. Launder the garment immediately either by hand or in the machine (whichever is most convenient for you).
To find out if your mascara will flake or run, check how much water it contains. The lower water is on the ingredients list, the less likely you'll get smeared. Still, experts suggest limiting your use of waterproof, smudge proof formulas made with little to no water.
