Why Aren’t My Child’s Baby Teeth Falling Out?

Posted by Dr. Jorgensen on October 20th, 2011

Missing front toothParents often worry that something is wrong when a child’s baby teeth do not fall out as expected. Although there are some developmental issues which require professional attention, most of the time everything is just fine. What should parents expect when it comes to their children losing baby teeth?

Baby teeth serve several purposes besides chewing. Primary teeth give rise to the permanent teeth and preserve space for them until they are developed enough to come in. If the baby teeth come out too early, space can be lost causing crowding of the underlying permanent ones. At the other extreme, baby teeth that are not lost on time can force the permanent ones to come in crooked creating a more difficult orthodontic condition.

The most common reasons for primary teeth to be lost early are decay, trauma, and crowding. If a tooth has to be pulled because of disease or is lost due to trauma, your dentist is usually already involved. If the teeth are crowded, your child may lose two primary teeth naturally to accommodate the eruption of a single larger permanent tooth. If baby teeth are lost prematurely, an orthodontist should be consulted to see if a space maintainer is needed.

There are several conditions which prevent the baby teeth from falling out on schedule. If the underlying teeth are crowded, they may not be able to push out the overlying baby teeth. Baby teeth with no underlying permanent replacements may be retained indefinitely. Extra teeth can block the normal eruption of the regular permanent ones. With a simple x-ray, your orthodontist can tell you if there really is a problem or if your child is just developing slowly.

The most common reason for parents’ concern however is just misunderstanding the normal sequence of tooth loss in their developing child. The first baby teeth are usually lost at about six years of age. Some children may lose theirs as early as five or as late as seven and neither variation is a problem. By age eight, the average child will have lost eight baby teeth; four front teeth on top and four front teeth on the bottom. Again, a variation of a year in either direction is nothing to worry about. Between the ages of eight and ten there is not much change in the number of teeth. In other words, it is normal for a child to lose eight teeth in a row and then stop for about two years! (It is during this two-year “break” that it is best to provide interceptive orthodontic treatment if it is needed.) Around ten years of age the remaining teeth begin to loosen and fall out. The average adolescent loses their last primary tooth before they are 13 years old. The 12-year-molars also make their appearance during that 12th year (hence the name).

Most questions about delayed tooth loss come during that two year span between eight and ten where no teeth are lost. Such inactivity is unexpected by parents but completely normal. In my practice I don’t worry about delayed tooth loss unless I can see that 1) the retained primary teeth are causing problems for the incoming permanent ones, 2) the 12-year molars are already erupted, or 3) the delayed tooth loss will cause orthodontic treatment to be started at an awkward age (i.e. the junior and senior years of high school). An important service that your orthodontist can provide is monitoring the dental development of your child and counseling with you about the need to have primary teeth removed if that should be necessary.

    I’m 16 about to be 17 soon and my baby teeth still didn’t fall out. My dentist told me one is getting ready to fall out and she can’t pull them out. She told me to take motrin to help the pain. But it hurts and sometimes the pain can be unbearable at times. My gum has been receding and the tooth looks extra long. Should I be concerned?

  2. Worried No More says:

    Thank you so much for this article.

    I have been quite concerned that my nearly 8 year old has yet to lose a single tooth. (She’s feeling pretty left behind as even her younger brother’s friends are starting to lose theirs at 5 years old.)

    Having read this article, I am SO relieved.

  3. Tiffany says:

    Thank you so much for this article, my oldest son lost his teeth fairly early but i have been worrying about my middle son and his lack of loose teeth at 7 1/2 years… I will take a deep breath and relax knowing he’s in normal range as well.

  4. Gonzalo says:

    I’m concerned that my son is 2 months shy of being 8 years old and still has not lost any of his top baby teeth. They are very small and seem to be getting smaller,I have set an appointment with dentist but would really like to know some answers about this if this will turn in to a bigger problem. Thanks
