Baby Teeth

My child has no teeth, he is 9 months old. Is there a problem that I should get checked out? I worry about this because he has been so early at all the other developmental stages.

Baby Teeth

Dr. Greene’s Answer:

For an infant, the mouth is an exquisitely sensitive portal connecting the world around him to his developing mind and body. He uses his mouth to meet his mother, to sate his constant hunger, to comfort himself between feedings, and to explore objects in the widening world around him. When hard teeth begin protruding into this soft, sensitive orifice, it is a major event in the life of an infant.

Many parents worry about the timing of the appearance of their children’s teeth. While the average time for the appearance of the first teeth is between five and seven months of age, there is a wide normal variation of timing. The teeth might come in as early as one month of age, or they might wait until a child is almost one-and-a-half-years old. Anywhere in this range can be normal.

Generally lower teeth come in before upper teeth, and generally girls’ teeth erupt earlier than those of boys (much like with everything else). Delayed eruption of all teeth may be the result of a nutritional problem, such as rickets, or a systemic condition, such as hypopituitarism or hypothyroidism.

Natal teeth or teeth present at birth are found in about one out of two thousand newborn infants. These are often extra teeth, but this should be confirmed radiographically before any attempt is made to remove them. Natal teeth may cause pain to the infant, poor feeding, and, if the baby is nursing, maternal discomfort. Natal teeth may also cause damage or even amputation of the tip of the newborn’s tongue due to strong sucking behavior. Early appearance of all teeth may indicate a hormonal problem such as hyperthyroidism.

The following tables outline the normal ranges for teeth to erupt and to shed:

Eruption of Primary or Deciduous Teeth

Upper Lower
Central incisors 6-8 months 5-7 months
Lateral incisors 8-11 months 7-10 months
Cuspids (canines) 16-20 months 16-20 months
First molars 10-16 months 10-16 months
Second molars 20-30 months 20-30 months

 

Shedding of Primary or Deciduous Teeth

Upper Lower
Central incisors 7-8 years 6-7 years
Lateral incisors 8-9 years 7-8 years
Cuspids (canines) 11-12 years 9-11 years
First molars 10-11 years 10-12 years
Second molars 10-12 years 11-13 years

 

Eruption of Permanent Teeth

Upper Lower
Central incisors 7-8 years 6-7 years
Lateral incisors 8-9 years 7-8 years
Cuspids (canines) 11-12 years 9-11 years
First premolars (bicuspids) 10-11 years 10-12-years
Second premolars (bicuspids) 10-12 years 11-13 years
First molars 6-7 years 6-7 years
Second molars 12-13 years 12-13 years
Third molars (wisdom teeth) 17-22 years 17-22 years

(Adapted from chart prepared by PK Losch, Harvard School of Dental Medicine, from Nelson’s Textbook of Pediatrics.)

If a permanent tooth becomes visible before the primary tooth above it has fallen out, generally the primary tooth should be extracted.

I hope that gives you enough to chew on!

    Hello!
    My son is 15 months old. He cut his first four teeth starting between 6 and 8 months. My concern is that he hasn’t cut anymore teeth and it’s been more than 6 months. Am I right to be concerned?

    Hello Doctor,

    My daughter is 10 months old and has no teeth. There are no signs of eruption. I am little worried about her development stages since girls teeth erupt much earlier than boys. I find all her actovoyiea are normal.

    Please suggest if I have to consult a paediatrician.
    Looking forward for your reply.

    Hi there,
    My daughter is almost 6 yrs old and has the smallest teeth I have ever seen. All her friends at school are losing their teeth and she is starting to feel left out. My daughter was born at 35 weeks and I was wondering if their is a connection between her being a premie and her very teeny tiny teeth.

    My baby is 5 months old and she is drooling I saw a little bit of blood on her shirt in the drool and looked in her mouth and where her two bottom teeth should come in at there are two..well they look like little flaps of skin coming out of her gums! I can move them back and forth very easily .. Are they her baby teeth but soft dark and rotten? Or does the skin do this before teeth come out!? I can’t find anything that looks like this online. I will make her an appt Monday but I’m worried now :-(

    Hello Dr. Green,
    My one year old has 7 teeth, with 2 bottom back teeth beginning to erupt. However, I fear she is out of eruption sequense. That doesn’t bother me as much as the fact that her left lateral incisor has not come in yet. The gums are hard there but no tooth. Should I be concerned. Should I call me pediatric dentist? Please help……
