Baby teeth and tooth eruption
Short answer: Czarkowski Pediatric Dentistry says the first baby teeth usually appear at about six to eight months and a child should have all 20 by around two and a half; the American Dental Association says about six months, with some children at 12 to 14 months[3][2].
Why does the practice say baby teeth matter?
The practice says baby teeth, also called primary teeth, matter for chewing and nutrition, speech and confidence, guiding permanent teeth into position, and preventing decay from spreading to permanent teeth still developing underneath[1].
What does the practice suggest before the first tooth appears?
The practice suggests cleaning a baby’s gums after feedings with a soft, damp cloth or gauze pad, avoiding sugary liquids in bottles or sippy cups between meals, and never putting a baby to bed with a bottle containing milk, juice or sweet liquids[1]. The American Dental Association likewise recommends wiping the gums with a clean, moist gauze pad or washcloth from the first days after birth[2].
When do baby teeth come in?
The practice says the first baby teeth are the two bottom front teeth, usually noticed at about six to eight months, followed by the four upper front teeth, with the rest appearing in pairs along the sides of the jaw until about two and a half years of age[3]. It says that at around two and a half a child should have all 20 teeth, and that the first permanent teeth begin to erupt between ages five and six[3]. The American Dental Association says the front four teeth usually come through at about 6 months, although some children do not have a first tooth until 12 or 14 months[2]. The practice adds that teeth a few months early or late are not a concern because all children are different[3].
What does the practice suggest once the first tooth appears?
The practice suggests brushing twice daily with a small, soft-bristled toothbrush and a smear (grain-of-rice size) of fluoride toothpaste, supervising brushing, and beginning to floss as soon as two teeth touch[1]. The American Dental Association gives the same smear amount for children younger than three and says to begin cleaning between teeth daily when two teeth touch[2]. See brushing and flossing.
When does the practice say to see a dentist?
The practice says a child should have a first dental visit by the time the first tooth appears and no later than the first birthday[1]. See first visit.
