When your child's front teeth, which were neat and even not long ago, suddenly look spread apart, it's natural to worry. Is a tooth about to fall out? Will the permanent teeth have gaps too? The short answer: gaps between baby teeth at this age are usually a good sign. Here's why, and what to watch for.
Gaps make room for the permanent teeth
Baby teeth are small, and the permanent front teeth that follow are much larger. A bigger tooth needs more space in the same spot. As your child's jaw grows, it slowly gets wider, but the baby teeth stay the same size, so gaps open between them. That's the natural way of making room so the permanent teeth can come in straight. Later, when the baby teeth fall out and the bigger permanent front teeth come in, they use these gaps to settle into place. You could say today's gaps are space being saved ahead of time.
So gaps between the front teeth around age five are normal, and they often show up evenly in several places. When gaps appear and how big they get varies from child to child. Even if they seem to have appeared overnight, in most cases they opened slowly as the jaw grew. Parents who look every day may actually notice them late.
In fact, baby teeth packed tightly with no gaps may leave too little room for the bigger permanent teeth, so they may come in crowded. That's why the dentist pays more attention when there are no gaps. Tight teeth don't always cause problems, but it's good to keep an eye on them together at checkups.
Common myths are that "gaps in baby teeth mean gaps in permanent teeth" or that "the gaps need to be closed." Gaps between baby teeth are preparation for the permanent teeth, and no treatment is needed to close them. If your child is bothered by the gaps or upset because a friend teased them, explain, "Your mouth is making room for your new teeth."
Leave the gaps alone, and just do this
- Leave the gaps alone. No treatment is needed to close them.
- If food gets stuck in a gap, gently clean it out with floss. Poking hard with a toothpick can hurt the gums.
- If thumb-sucking or tongue thrusting is still going on, help your child stop now. These habits can push the front teeth forward and affect the alignment and bite. Rather than scolding, redirect idle hands to other play, and praise your child on days they hold off.
- Prepare food in a size and texture that suits your child's age, and encourage them to chew it well. It's good for the jaw and teeth to get a real workout. Hard or round foods can be a choking risk, so take care.
- Gaps make it easier for food to get stuck, so finish the bedtime brushing yourself.
Taking a photo of the front teeth every few months to track how the gaps change makes it easy to show the dentist at checkups. Using the same angle and lighting makes changes easier to compare. Taking one photo with the mouth closed and one with a big "cheese" smile showing the front teeth also helps when looking at the bite.
Frequently asked questions
Do the gaps mean a tooth is about to fall out?
Gaps forming and teeth falling out are two different things. But if a baby tooth is loose along with the gaps, show it to the dentist at the next checkup.
My child's teeth are tight with no gaps. Is that okay?
Tight teeth don't always cause problems. But the permanent teeth may come in crowded, so the dentist checks ahead of time. Mention it at the checkup.
There's an especially big gap between the two upper front teeth.
The gap itself is nothing to worry about. If one spot looks much wider than the rest, show it to the dentist at the next checkup.
Food keeps getting stuck in the gaps. What should I do?
Gently clean it out with floss after meals or before bed. No treatment to close the gaps is needed, so just remove stuck food as it happens. Leaving food stuck there for a long time makes a cavity more likely in that spot.
When should we get an orthodontic consultation?
The American Association of Orthodontists recommends a first orthodontic checkup no later than age 7. Even before then, if the lower jaw sits noticeably forward or the upper and lower front teeth don't meet, ask for a consultation.
Show the dentist if
- The lower jaw seems to sit noticeably forward
- The upper and lower front teeth don't meet when the mouth is closed
- One spot is much wider than the rest
