As a parent, noticing your child’s teeth developing in unusual ways can be concerning—especially when their front teeth begin to noticeably protrude. Commonly referred to as “buck teeth,” this dental condition is more than just a cosmetic issue. It can affect a child’s speech, bite, self-confidence, and even their ability to close their lips comfortably.
The good news? Buck teeth are treatable—and early intervention can make a world of difference.

What Are Buck Teeth?
Buck teeth, medically known as an overjet, occur when the upper front teeth project out significantly further than the lower teeth. While a mild overjet is normal in young children, a more pronounced appearance may require dental evaluation and treatment.
Common Causes of Buck Teeth in Children
Several factors can contribute to the development of buck teeth:
✅ Genetics
In many cases, overjets are inherited. If you or your partner had buck teeth as a child, there’s a chance your child may develop them too.
✅ Thumb Sucking or Dummy Use
Prolonged thumb sucking or pacifier use beyond the toddler years can exert pressure on the upper front teeth, pushing them outward.
✅ Tongue Thrusting
Some children push their tongue forward against their front teeth when they swallow or speak. Over time, this can move the teeth out of alignment.
✅ Mouth Breathing
Chronic mouth breathing, often caused by allergies or enlarged tonsils/adenoids, can affect the shape of the jaw and the alignment of teeth.
When Should You See a Dentist?
If your child’s front teeth are noticeably protruding or if they’re struggling to close their lips properly, it’s a good idea to book a dental check-up. The best time for an orthodontic assessment is typically around age 7, even if baby teeth are still present. Early evaluation can allow for timely, less invasive treatment options.
How Are Buck Teeth Treated?
Treatment depends on the age of the child, the severity of the overjet, and the underlying cause:
- Orthodontic appliances like expanders or headgear (for younger kids)
- Braces or clear aligners to reposition teeth (usually in the pre-teen or teen years)
- Behavioral interventions for thumb sucking or tongue thrusting
- Myofunctional therapy to help correct oral habits and improve muscle function
Early intervention often leads to better outcomes and can even reduce or eliminate the need for more complex treatments later on.
Tips to Help Prevent or Reduce Buck Teeth
- Try to stop thumb sucking or dummy use by age 3
- Encourage your child to breathe through their nose and speak to your GP or ENT if they show signs of mouth breathing
- Ensure your child sees a children’s dentist regularly, especially if you notice changes in their bite or jaw alignment
- If your child struggles with tongue thrusting, ask your dentist about myofunctional therapy
