Overjet vs. Overbite: Understanding Dental Misalignments

Understanding Dental Misalignments

Many people confuse overjet and overbite, two common dental conditions that can impact oral health and overall confidence. Let’s dive deep into these misunderstood dental terms and separate fact from fiction.

What exactly is Overjet?

Overjet, often called “buck teeth,” is a horizontal misalignment where upper front teeth protrude outward. Key points include:

Normal tooth alignment shows upper teeth sitting about 2 millimeters in front of lower teeth
Overjet occurs when this horizontal separation exceeds 2 millimeters
Can make teeth appear to stick out or look crooked

Common Myths About Overjet
– Myth: Only children get overjet
– Reality: Overjet can affect people of all ages

– Myth: Overjet is just a cosmetic issue
– Reality: It can cause serious oral health problems

Exploring Overbite: More Than Just Appearance

Overbite represents a vertical misalignment where upper front teeth overlap lower front teeth. Important details include:

A typical overbite ranges from 2 to 4 millimeters
Over 30% overlap is considered problematic
Also known as “deep bite” or “closed bite”

Debunking Overbite Misconceptions
– Myth: Overbite doesn’t affect overall health
– Reality: Can cause speech difficulties and jaw pain

– Myth: Only severe cases need treatment
– Reality: Even mild overbites can benefit from intervention

What Causes These Dental Misalignments?

Multiple factors contribute to overjet and overbite:

1. Genetic predisposition
2. Jaw size variations
3. Childhood habits like:

• Thumb sucking
• Prolonged pacifier use
• Tongue thrusting

4. Tooth loss
5. Abnormal jaw development
