Common Dental and Orthodontic Patterns in Asian Patients

Someone asked Dr. Shauna Fung about this recently, and it’s a great question: are there dental or orthodontic patterns that come up more commonly in Asian patients?

After nearly 20 years in orthodontics — and many years practicing in communities with large Asian populations — Dr. Fung has noticed some recurring patterns. Not every patient fits a mold, of course. But understanding common trends can help patients and parents know what to look for and when to seek an evaluation.

Shovel-Shaped Incisors

One of the most well-known genetic dental traits in East Asian populations is shovel-shaped incisors — upper front teeth with ridges along the inner edges that give them a slightly concave shape when viewed from the back.

Shovel-shaped incisors are a normal variant, not an orthodontic problem on their own. But they can make the front teeth appear slightly more prominent, and they’re sometimes associated with crowding or spacing issues worth monitoring over time.

Underbite

An underbite — where the lower jaw or lower teeth sit in front of the upper teeth — appears at higher rates in East Asian populations compared to others. It’s often genetic in origin and can range from mild to significant.

Underbites are worth addressing early. When the bite is off, it can affect chewing, jaw function, and facial balance over time. In children, early treatment can guide jaw growth in a more favorable direction before the bones are fully developed.

Crowding

Crowding — where there isn’t enough space in the jaw for all the teeth to fit properly — is one of the most common orthodontic issues across all patient groups. In some Asian patients, crowding can be especially noticeable when a slightly narrower arch combines with teeth that are on the larger side relative to the jaw.

Crowding doesn’t resolve on its own. Without treatment, teeth can twist, overlap, or push others out of alignment. Braces or clear aligners are very effective at creating space and aligning the full arch.

Spacing and Pegged Lateral Incisors

Some Asian patients present with the opposite of crowding — noticeable gaps. Pegged lateral incisors (smaller than normal side front teeth, often cone-shaped) are a genetic variant seen at higher rates in certain populations. These can leave visible gaps between the front teeth and may benefit from a combination of orthodontic and restorative dental treatment.

Why Early Evaluation Matters

For underbites in particular, early evaluation makes a real difference. A first orthodontic check-up at age 7 — or earlier if there are visible concerns — gives Dr. Fung the chance to identify jaw development issues while there’s still growth potential to work with.

For crowding and other issues, early evaluation helps with planning, even if active treatment starts later.

Every Patient Is Different

Genetics sets the stage, but treatment is always tailored to the individual. If you’ve noticed any of these patterns in yourself or your child, a consultation is the best next step.
