Eruption of Your Child’s Teeth

The eruption of primary teeth (also known as deciduous or baby teeth) follows a similar developmental timeline for most children.  A full set of primary teeth begins to grow beneath the gums during the fourth month of pregnancy. For this reason, a nourishing prenatal diet is of paramount importance to the infant’s teeth, gums, and bones.

Generally, the first primary tooth breaks through the gums between the ages of six months and one year.  By the age of three years old most children have a “full” set of twenty primary teeth.  The American Dental Association (ADA) encourages parents to make a “well-baby” appointment with a pediatric dentist approximately six months after the first tooth emerges.  Pediatric dentists communicate with parents and children about prevention strategies, emphasizing the importance of a sound, “no tears” daily home care plan.

Although primary teeth are deciduous, they facilitate speech production, proper jaw development, good chewing habits, and the proper spacing and alignment of adult teeth.  Caring properly for primary teeth helps defend against painful tooth decay, premature tooth loss, malnutrition, and childhood periodontal disease.

In what order do primary teeth emerge?

As a general rule-of-thumb, the first teeth to emerge are the central incisors (very front teeth) on the lower and upper jaws (6-12 months).  These (and any other primary teeth) can be cleaned gently with a soft, clean cloth to reduce the risk of bacterial infection.  The central incisors are the first teeth to be lost, usually between 6 and 7 years of age.

Next, the lateral incisors (immediately adjacent to the central incisors) emerge on the upper and lower jaws (9-16 months).  These teeth are lost next, usually between 7 and 8 years of age.  First molars, the large flat teeth towards the rear of the mouth, then emerge on the upper and lower jaws (13-19 months).  The eruption of molars can be painful.  Clean fingers, cool gauzes, and teething rings are all useful in soothing discomfort and soreness. First molars are generally lost between 9 and 11 years of age.

Canine (cuspid) teeth then tend to emerge on the upper and lower jaws (16-23 months).  Canine teeth can be found next to the lateral incisors and are lost during preadolescence (10-12 years old).  Finally, second molars complete the primary set on the lower and upper jaw (23-33 months). Second molars can be found at the very back of the mouth and are lost between the ages of 10 and 12 years old.

What else is known about primary teeth?

Though each child is unique, baby girls generally have a head start on baby boys when it comes to primary tooth eruption.  Lower teeth usually erupt before opposing upper teeth in both sexes.

Teeth usually erupt in pairs – meaning that there may be months with no new activity and months where two or more teeth emerge at once.  Due to smaller jaw size, primary teeth are smaller than permanent teeth, and appear to have a whiter tone.  Finally, an interesting mixture of primary and permanent teeth is the norm for most school-age children.

My mother is in a nursing home in Harrisville Michigan. She dropped her dentures and broke a tooth. The entire staff was in her room trying to find the broken tooth, but it must have fallen into the heat register or something. Anyway it never turned up. My brother, Rick, went to visit and called to tell me about it. "We have to do something," he told me. "I can't stand to see mom looking like this." He was planning to take a few days off and take me up north to see about getting her to the dentist to get her plate fixed. I went online and called several dentists in the area. They could not help me with the problem. Then I found Dr. Gregg Resnick DDS in Alpena. He said he could fix them and have them ready by the next day. I had our friends, Shirley and Tom Harmon, pick up the plate and take it to his office. The doctor called me (I live over 200 miles from where my mom is). Dr. Resnick was concerned that he might not be able to grind the tooth properly and that my mom wouldn't be able to chew properly. You see he was under the impression she had a full set of dentures and didn't realize that she had some lower teeth. He told me that although the tooth was broken mom would not have a problem chewing with it that way. "But, we do have a problem," I told him. "My brother can't stand to look at her with that broken tooth." He sighed and said, "Let's do it then." I could have hugged him through the phone. I promised him that if mom had a problem chewing that I would bring her handicap van and get her to his office the next day. Well, mom got her plate today. She ate dinner and said that she could chew just fine. I have Dr. Resnick to thank for this. He did me a favor and it worked out just fine. I wish there were more dentists like him. He and his staff gave me 5 star service.

My name is Brad Boehm. I am a local physician in Alpena, Michigan. I had an erosion problem with my teeth that made them appear yellow and deformed. I went to see a cosmetic dentist in Atlanta, Georgia. The repair work to my teeth including veneers was over $70,000. I came home very depressed. While at a routine cleaning I discussed this with Dr. Gregg Resnick, my new dentist. He formulated a treatment plan that was identical to the plan from Georgia at less than one-third the cost. I am sure the cost in Georgia included partial rent payment for the mansion the clinic was located in.

I chose to have my teeth fixed by Dr Resnick and I truly could not be happier! During the treatment process minor adjustments were made. This required a quick end of the day visit to see Dr. Resnick instead of a day or two wasted flying to Atlanta. My family and friends comment all the time about my teeth and how I smile so much more. I would recommend Dr. Resnick to anyone who wishes to improve their smile.

I first met Dr. Resnick 20 years ago when referred by a friend for emergency care. Now Nancy and I are thankful he has been our dentist ever since. We think of our appointments as going to an office where we will be treated as friends, not only by him, but also by the staff.

Dr. Resnick is always calm, patient, encouraging and knowledgeable in dental care. His staff reflects his demeanor. Furthermore, he is an interesting guy.

He is always interested in patients as individuals outside of the office. I remember telling him of impending surgery and later he called me at home to encourage and wish me well.

We recommend him to all our friends.
