Many patients in Hartford and surrounding Connecticut suburbs ask the same questions during dental visits:

  • Is my bite normal?

  • What’s the difference between an overbite and an underbite?

  • Do I really need orthodontics if I’m not in pain?

A healthy bite—also called proper occlusion—is one of the most important and overlooked aspects of long-term oral health. Beyond straight teeth, your bite directly affects tooth wear, gum health, bone stability, and oral hygiene.

Let’s break down what a healthy bite looks like, common bite problems, and how orthodontics can protect your smile for life.


What Is a Bite (Occlusion)?

Your bite, or occlusion, describes how your upper and lower teeth come together when you close your mouth, chew, or speak.

A healthy bite allows:

  • Even distribution of chewing forces

  • Minimal stress on teeth and jaw joints

  • Healthy gums and bone

  • Easier brushing and flossing

When the bite is misaligned, patients in Hartford often experience:

  • Chipped or worn teeth

  • Gum recession

  • Bone loss

  • Crowding that traps plaque

  • Jaw discomfort or fatigue


What Is an Overbite?

An overbite occurs when the upper front teeth overlap the lower front teeth vertically.

Is an Overbite Normal?

Yes—a slight overbite is healthy. Problems occur when the overlap is excessive, known as a deep bite.

Problems Caused by a Deep Overbite

  • Excessive wear on lower front teeth

  • Chipping or fracturing of upper teeth

  • Gum irritation behind upper teeth

  • Increased risk of tooth sensitivity

  • Long-term jaw strain

Many Hartford patients don’t realize that deep overbites can cause silent damage long before pain appears.


What Is an Underbite?

An underbite occurs when the lower teeth sit in front of the upper teeth.

Why Underbites Matter

Underbites are often related to jaw growth patterns and can lead to:

  • Difficulty chewing efficiently

  • Uneven tooth wear

  • Speech challenges

  • Increased stress on the jaw joints (TMJ)

From a periodontal perspective, underbites can cause abnormal forces on specific teeth, accelerating gum recession and bone loss, especially in adults.


What Is a Crossbite?

A crossbite happens when one or more upper teeth bite inside the lower teeth instead of outside.

Why Crossbites Are Serious

Crossbites are one of the most damaging bite problems we see in West Hartford, Glastonbury, and Newington patients, because they:

  • Create uneven chewing forces

  • Cause accelerated tooth wear

  • Increase fracture risk

  • Lead to gum recession on affected teeth

In children, untreated crossbites can also affect jaw development, making early orthodontic evaluation critical.


What Is the Ideal Bite?

An ideal bite isn’t about perfection—it’s about balance, function, and health.

Characteristics of a Healthy Bite

  • Upper teeth slightly overlap lower teeth

  • Back teeth interlock evenly like gears

  • No single tooth absorbs excessive force

  • Jaw closes comfortably without shifting

  • Balanced contact on both sides

When Hartford patients have a healthy bite:

  • Teeth last longer

  • Gums stay healthier

  • Bone remains more stable

  • Oral hygiene becomes easier


How a Healthy Bite Improves Periodontal Health

Many people don’t realize how closely bite alignment and gum health are connected.

When teeth are misaligned:

  • Plaque builds up more easily

  • Certain teeth experience chronic trauma

  • Gums become inflamed or recede

  • Bone loss accelerates in overloaded areas

A healthy bite helps:

  • Reduce trauma to teeth

  • Improve periodontal stability

  • Support long-term gum health

  • Lower the risk of tooth loss

In short, orthodontics can be preventive dentistry, not just cosmetic treatment.


How Orthodontics Helps Create a Healthy Bite

Orthodontic treatment aligns teeth and jaws into a more functional, stable position, improving both appearance and health.

Benefits of Orthodontics for Hartford Patients

  • Balanced chewing forces

  • Reduced tooth wear and fractures

  • Easier brushing and flossing

  • Reduced gum inflammation

  • Lower risk of future dental procedures


Orthodontic Options for a Healthy Bite in Hartford, CT

1. Traditional Braces

  • Ideal for complex bite problems

  • Precise tooth and jaw control

  • Excellent for severe overbites, underbites, and crossbites

2. Clear Aligners (Invisalign®)

  • Great for mild to moderate bite issues

  • Easier oral hygiene during treatment

  • Popular with adult patients in West Hartford and Avon

3. Early Orthodontic Treatment for Children

  • Guides jaw growth

  • Prevents worsening bite problems

  • Can reduce the need for surgery or extractions later


Do You Need Orthodontics If You’re Not in Pain?

This is one of the most common questions we hear in Hartford dental offices.

Pain is not a reliable indicator of bite problems.

Many bite issues cause:

  • Slow tooth wear

  • Gradual gum recession

  • Microfractures

  • Silent bone loss

By the time pain appears, significant damage may already exist.


Why a Healthy Bite Is an Investment in Your Smile

A healthy bite means:

  • Less trauma to teeth

  • Better periodontal health

  • Improved oral hygiene

  • Fewer costly dental repairs over time

Orthodontics isn’t just about straight teeth—it’s about protecting your smile, gums, and bone for decades to come.

If you live in Hartford, West Hartford, East Hartford, Glastonbury, Bloomfield, Newington, or nearby Connecticut communities, and have been told you have an overbite, underbite, or crossbite—or you’ve noticed uneven wear or gum recession—a comprehensive bite evaluation may significantly improve your long-term oral health.
