An underbite happens when your lower teeth stick out farther than your upper teeth when your mouth is shut. At Carpinello Orthodontics in Drexel Hill, Newtown Square, and Edgmont, Dr. Paul Carpinello and Dr. David Carpinello focus on addressing this issue, which can impact both your oral health and self-esteem. If ignored, underbites can lead to challenges with speaking, eating, and may cause ongoing jaw pain.
Causes and Risk Factors

Genetics factors of underbite
Genetics significantly influence the development of an underbite, often appearing in families. If a parent has an underbite, there is a higher chance that their child may develop one due to hereditary influences.

The role of environmental factors in underbite
Environmental elements significantly influence the development of an underbite, a dental condition characterized by the lower jaw extending beyond the upper jaw.

Mouth breathing and its relationship to underbite
Mouth breathing, often resulting from allergies or respiratory challenges, can interfere with normal jaw development. Incorrect tongue posture and pressure from mouth breathing may affect jaw growth, potentially resulting in an underbite.
Types and Severity of Underbite
At Carpinello Orthodontics, we categorize underbites into three primary types: Class I (mild overlap), Class II (moderate overlap), and Class III (severe protrusion). We carefully evaluate each patient’s condition to determine the most effective treatment approach. We also assess any temporomandibular joint (TMJ) involvement, as this can influence treatment decisions.
