Class 3 Bite: Causes, Treatment Options & How to Fix an Underbite

An underbite, or Class 3 malocclusion, is a dental condition in which the lower teeth protrude beyond the upper teeth. This misalignment may affect appearance, speech, and oral health. This blog will discuss Class III bite causes, treatment options, and how to effectively fix an underbite.

What is Class 3 Bite?

Class 3 bite refers to an abnormality in bite whereby the mandible has moved forward. In this case, the lower teeth overlap with the upper teeth while chewing or speaking. Less common than overbites, this condition can pose serious complications for dentofacial problems.

Causes of Class 3 Bite

Understanding underbite causation is important in the proper management of the condition. The following are the most common causes:

1. Genetics

Genetics are involved with jaw development. In case, one or both parents have an underbite, the child may inherit it.

2. Jawbone Development Issues

Unequal growth of the upper or lower jaw may cause a misalignment. This is often during childhood.

3. Childhood Habits

Thumb sucking, pacifier use, or tongue thrusting may cause teeth to get out of alignment.

4. Accidents or Injuries

Severe facial injuries may damage the jaw thereby engendering an underbite.

5. Tumors or Cysts

Abnormal jaw bone growths in the jawbone or mouth may disrupt tooth alignment.

Symtopms of Cass 3 Bite

An underbite is not simply a cosmetic problem. It mainly manifests in a range of symptoms that include:

• Problems with chewing or biting.
• Problems with speech, such as lisps or slurred speech.
• Jaw pain or temporomandibular joint disorders.
• Increased wear and tear on tooth enamel.
• Asymmetry of the face or protruding chin.

How is Class 3 Bite Diagnosed?

A Class 3 bite can be diagnosed by:

• Conducting a visual assessment of your teeth and jaw.
• Using dental X-rays to see bone structure.
• Taking impressions of your teeth for models.
• Using photographs of the face and smile for evaluation.

Treatment Option for Class 3 Bite

Here are some options for treatment:

1. Braces

Conventional braces are usually preferred in the treatment of underbite conditions. The brackets and wires gradually shift the tooth movements into their original positions.

2. Clear Aligners

These are discreet alternatives to braces. They can be effectively used for mild to moderate underbites.

3. Upper Jaw Expanders

For children, upper jaw expanders can increase their upper jaw width to match the lower jaw. This is effective and works during growth stages.

4. Reverse-Pull Headgear

This is an orthodontic appliance that pulls the upper jaw forward, which can be helpful in treating an underbite. It is generally used in younger people.

5. Tooth Extraction

In some cases, extracting one or more teeth creates the space needed for proper alignment.

6. Jaw Surgery (Orthognathic Surgery)

Severe cases of an underbite require shifting of the jaw, and this is done when one is an adult.

7. Chin Cap

This is a non-surgical option for children. It restricts the growth of the lower jaw to correct the underbite.

How to Fix an Underbite: Step-by-Step Guide

Correcting an underbite is a slow process. Here’s what to expect:

Step 1: Consultation

Visit an orthodontist to evaluate the situation thoroughly. The orthodontist will suggest a treatment plan tailored to your case.

Step 2: Early Intervention-For Children

If detected early, an underbite can be tampered with non-surgically by expanders or headgear.

Step 3: Under Orthodontic Treatment

Fixing teeth and bites with braces or aligners. Depending on the degree of underbite correction required, this phase may take 1-3 years.

Step 4: Surgical Correction

If severely underbite, jaw surgery can be indicated to fix the position of the jawbone.

Step 5: Retention After Treatment

Retainers keep the new positioning after treatment and void relapse.

Can a Class 3 Bite Be Prevented?

Reduce the risk of having an underbite though it is genetics:

• Discourage thumb sucking or pacifier use in children.
• Encourage proper tongue posture.
• Regular dental visits for early detection.

Living with a Class 3 Bite: Tips and Advice

Here are some tips to help you manage with an underbite:

• Maintain good oral hygiene to keep dental problems at bay.
• Stay away from hard or sticky foods that can break teeth.
• Orthodontic wax can be used to reduce discomfort caused by braces.
• Follow the instructions given by your orthodontist.

Long-Term Effects of an Untreated Class 3 Bite

In the case of an untreated underbite, chronic problems will develop, including:

• Chronic jaw pain or TMJ disorders.
• Eating or speaking difficulties.
• More chances of cavities and gum disease.
• Feeling inferior because of facial asymmetry.

Cost of Treating a Class 3 Bite

The cost of treatment for underbite varies according to the procedure selected:

• Braces range from $3,000 to $7,000.
• Clear Aligners starting from $1,120.
• Jaw Surgery ranges from $20,000 to $40,000.
