Baby teeth start falling out at around age 6, usually starting with the lower central incisors, and the changeover finishes between ages 11 and 12 with the second molars.<\/strong> During these years baby teeth and permanent teeth exist side by side, a stage known as mixed dentition.<\/p>\n<\/div>\n\n\n\n\n\t\t\t<\/div> \n\t\t<\/div>\n\t<\/div> \n<\/div><\/div>\n\t\t

When Do Baby Teeth Start Falling Out<\/h2>\n

The permanent tooth forms underneath the baby tooth and, as it grows, gradually dissolves its root. That's why the baby tooth starts to wobble and eventually falls out on its own. The first one usually falls out between ages 6 and 7, although it's normal for it to happen a little earlier or later.<\/p>\n

Girls tend to be slightly ahead of boys.<\/p>\n<\/div>\n\n\n\n\n\t\t\t<\/div> \n\t\t<\/div>\n\t<\/div> \n<\/div><\/div>\n\t\t

Order in Which Baby Teeth Fall Out<\/h2>\n

This is the approximate sequence, according to the American Dental Association:<\/p>\n\n\n\n\n\n\n\n\n\n
Baby tooth<\/th>\nApproximate age it falls out<\/th>\n<\/tr>\n<\/thead>\n
Central incisors<\/strong><\/td>\n6-7 years<\/td>\n<\/tr>\n
Lateral incisors<\/strong><\/td>\n7-8 years<\/td>\n<\/tr>\n
First molars<\/strong><\/td>\n9-11 years<\/td>\n<\/tr>\n
Canines<\/strong><\/td>\n9-12 years<\/td>\n<\/tr>\n
Second molars<\/strong><\/td>\n10-12 years<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

In general, the lower teeth fall out before the upper ones.<\/p>\n<\/div>\n\n\n\n\n\t\t\t<\/div> \n\t\t<\/div>\n\t<\/div> \n<\/div><\/div>\n\t\t

How Many Baby Teeth Are There and How Many Fall Out<\/h2>\n

We have 20 baby teeth and they all fall out. They are replaced by 28 permanent teeth, which become 32 if the wisdom teeth come through.<\/p>\n

There's one important detail to bear in mind: the 6-year molar doesn't replace any baby tooth<\/strong>. It comes through behind the baby molars and is permanent, although many families mistake it for a baby tooth. It needs careful brushing, as it's one of the molars most at risk of decay.<\/p>\n<\/div>\n\n\n\n\n\t\t\t<\/div> \n\t\t<\/div>\n\t<\/div> \n<\/div><\/div>\n\t\t

What If the Permanent Tooth Comes Through Before the Baby Tooth Falls Out?<\/h2>\n

Pasa a menudo con los incisivos inferiores: el definitivo asoma por detr\u00e1s y el de leche sigue en su sitio. Es lo que se conoce como \u00abdientes de tibur\u00f3n\u00bb, por la doble fila.<\/p>\n

Often the baby tooth falls out on its own within a few weeks and the tongue pushes the permanent tooth into position. If after one or two months it hasn't fallen out, or isn't moving at all, have it checked by a paediatric dentist. Sometimes it needs to be extracted so the permanent tooth can take its place.<\/p>\n<\/div>\n\n\n\n\n\t\t\t<\/div> \n\t\t<\/div>\n\t<\/div> \n<\/div><\/div>\n\t\t
