The Genetics Behind a Smile

Genetics influence many aspects of your child’s oral health, including:

• Jaw size and shape – A small jaw from one parent combined with larger teeth from the other can cause crowding.

• Tooth size and spacing – Gaps or crowding may be inherited traits.

• Bite alignment – Overbites, underbites, and crossbites can often run in families.

If you or other close family members had orthodontic treatment as kids, there’s a higher chance your child may need it too.

When Habits Play a Bigger Role

While genetics set the foundation, environmental and lifestyle factors can also impact tooth alignment:

• Thumb sucking or prolonged pacifier use beyond age 3

• Mouth breathing due to allergies or enlarged tonsils

• Early loss of baby teeth from decay or injury

These factors can shift teeth out of place even if genetics aren’t to blame.

Early Evaluation is Key

The American Association of Orthodontists recommends a first orthodontic evaluation by age 7. This allows dentists to:

• Spot genetic alignment issues early

• Guide jaw growth to create space for incoming adult teeth

• Prevent more complex treatment later on

At Sedona Molar Kids Dentistry, we work closely with orthodontists to track dental development and recommend treatment only when it’s truly needed.
