Protruding teeth (also known as buck teeth) is one of the six teeth conditions that Zenyum Invisible Braces can help fix. But have you wondered what it really means?
There may be a couple of reasons why you may have protruding teeth - from genetics to habits you may have developed as a child. This article will cover possible causes, symptoms, potential issues and treatment for buck teeth.

You'll know you have buck teeth if you find that your upper front teeth protrude outwards over your lower teeth. In dental terms, this is called an "overjet," and it's one of the most common reasons people in Singapore seek teeth straightening. This condition can range from a mild, barely noticeable overlap to a more significant protrusion. It's not just about how your smile looks; a noticeable overjet can sometimes affect how you chew and speak.
There's a few reasons why you may end up having buck teeth. Let's find out why!
Sometimes, the habits we had as children can affect how our teeth develop. Thumb sucking actually applies pressure to your front teeth, pushing them outwards. As such, their natural position is shifted and this may lead to protrusions.
One more thing that could cause buck teeth is tongue-thrusting. This happens when your tongue presses too far forward in your mouth. While children normally do this, it is a habit that can carry on into adulthood.
If you've got a missing tooth, or additional teeth, this can affect your teeth alignment and result in you having buck teeth. Not having sufficient space for your teeth to move can also lead to alignment issues.
In many cases, protruding or buck teeth are due to the underdevelopment of the lower jaw causing it to be shorter than the upper jaw. Having missing, extra, or impacted teeth may even change the development of your jaw since your remaining teeth begin to shift; affecting the position of your front teeth, and leading to protrusions.
Having buck teeth can be unsightly and may make you feel self-conscious about showing your smile. Here are a few symptoms you may experience that may urge you to get your buck teeth fixed:
A straight smile can boost your confidence. However, not everyone has naturally well aligned teeth. With buck teeth, you may experience several issues and problems like these:
Fortunately, buck teeth are treatable by a dentist or orthodontist. The most common solution is braces, either traditional metal brackets and wires or clear aligners, like what Zenyum provides. These gradually shift the teeth into proper alignment over time.
For severe misalignment or jaw issues, surgery might be necessary to reposition the jawbone itself, as advised by your dentist. Early intervention is ideal, particularly for growing children, but adults can also achieve a straighter smile by wearing clear aligners.

Invisible braces is one of the ways that can help correct protruding teeth. As they apply pressure on your teeth to move them into new positions, your treating dentist may advise you to do Interproximal Reduction (IPR) to create space for your teeth to move.

Here's another way to get straighter teeth, and one that you may have heard of. Traditional metal braces have been around for some time as the go-to solution before clear aligners were available as a treatment options.
Of course, it might be more noticeable compared to clear aligners (as you'll end up with a mouth full of metal!) but traditional braces do have their fair share of benefits.
Other ways to correct buck teeth would be veneers and dental bonding.
Editor’s Tip: When choosing a treatment, think about your lifestyle. If you have a busy job or don't want the look of traditional braces, clear aligners are often the perfect fit. You can still enjoy your favourite foods like laksa or chili crab without worry!
If you’re exploring aligners for buck teeth treatment, Zenyum offers different levels of solutions depending on how complex your case is. Each option is designed to balance effectiveness with convenience, so you can choose what best fits your needs.
ZenyumClear™ is best suited for mild buck teeth cases that involve only slight forward tilting of the front teeth. It focuses on gentle, aesthetic adjustments to bring minor protrusion back into better alignment, ideal for those seeking a subtle improvement in their smile’s balance without extensive treatment.
While primarily cosmetic, this entry-level option still uses precise digital planning to ensure predictable, controlled movement of the front teeth. If greater correction or bite adjustment is required, your Zenyum-partnered dentist may recommend upgrading to ZenyumClear™ Plus or Extra for a more comprehensive result, all while keeping your aligner journey nearly invisible.
ZenyumClear™ Plus provides enhanced movement control for moderate buck teeth cases where the front teeth protrude slightly but jaw alignment remains normal. It allows for more extensive front-to-back tooth adjustments compared to the base ZenyumClear™ system, while maintaining a discreet, clear appearance.
This option is often suitable when mild protrusion affects the smile’s balance or lip support but doesn’t require extractions or complex orthodontic mechanics. Through digital planning and periodic dentist reviews, ZenyumClear™ Plus helps guide the upper teeth into a more harmonious position, offering noticeable improvement in profile and alignment without compromising aesthetics or comfort.
Designed for more involved mild-to-moderate buck teeth cases, ZenyumClear™ Extra offers the most advanced level of aligner treatment within the Zenyum lineup. It provides greater tooth movement control and precision through full-arch adjustments and the use of attachments on multiple teeth when needed.
This option may help reduce the forward protrusion of the upper front teeth, especially when caused by dental misalignment rather than jaw structure. However, for severe or skeletal-related buck teeth, your Zenyum-partnered dentist may recommend other approaches to achieve the best long-term results.
No matter which option you choose, all ZenyumClear™ aligners are removable, easy to clean, and much less noticeable than braces, giving you flexibility and comfort throughout your treatment.

From having buck teeth to a well aligned smile, this customer had a total of 30 aligner sets over 10 months, and only had to visit their dentist 4 times for fitting, mid-treatment check-ins and post-treatment review.
