What Causes Toddler Underbite and How to Treat It

An underbite in children is one of the popular alignment issues. When your youngster bites down, their upper teeth will protrude somewhat more than their lower teeth. On the other hand, an underbite causes the lower teeth to jut out further than the upper teeth. When the lower jaw moves forward, it causes an underbite, a class III orthodontic misalignment, malocclusion. In the normal development of your teeth, the front teeth should be a little bit over the lower teeth.

If your toddler has an underbite, this isn’t anything to be concerned about, but it would help to consider treatment options for this dental condition. It’s always better to receive an earlier treatment than late.

What causes underbite?

You can see signs of underbite in your children just by looking at their faces, but there are other signs to look out for that could indicate that your child is developing this type of malocclusion. An underbite can be spotted in children who have trouble eating, have speech issues, snore or experience sleep apnea.

The development of an underbite is strongly influenced by genetics. Was there a family history that a family member experienced underbite? If this is the case, your child has a higher probability of developing one as well. Thumb sucking, tongue pushing, prolonged use of a pacifier or bottle, and injuries to the jaw are all common causes of underbites in children besides heredity.

Is it normal for toddlers to have an underbite?

An underbite is a pretty common issue among youngsters. If you’ve noticed that your child has an underbite, you should talk to your dentist about it and make an appointment with an orthodontist right away.

If your child has an underbite, the best time to treat them is 7 to 10. Widening the upper jaw, for example, can allow permanent teeth to emerge in a more favorable location than they would have otherwise.

An early orthodontic treatment plan would substantially impact the overall dental health of every child who needs it.

Do you need to correct your child’s underbite?

Underbites can cause chewing and eating issues, excessive jaw pain (such as TMJ), difficulty speaking, risk of tooth decay due to worn down enamel, sleep apnea, snoring, and difficulty sleeping.

Because of the numerous difficulties, an underbite should be addressed immediately once noticed. Fortunately, there are different ways available such as braces, orthodontic appliances, and surgery.

How can you fix a toddler’s underbite?

Dental treatments for your child’s underbite depend on how extreme or mild it is. Moreover, common treatments are the following:


You may only fix an extreme underbite through underbite surgery. Surgery should only be considered as a last option following extensive discussion with your child’s dentist.


Your child’s orthodontist can create a special appliance for your child’s mouth. Among them are expanders, retainers, and headgear.


Braces can correct different forms of misalignment, including bite issues. It is also one of the most common ways to correct an underbite. Children can have questions about getting braces or be self-conscious about looking with metal ones. They have the option of clear braces, which are less apparent than metal braces.

Upper jaw expander

An upper jaw expander is a simple appliance that is used to place across your child’s palate. It’s is a wire-frame device. You press a specific key to slightly widen the jaw expander each night. This procedure leads the upper jaw to broaden until there is no longer an underbite. Patients often wear this gadget for about a year before switching to a retainer to keep their teeth in place.
