An open bite is a type of malocclusion where the upper and lower teeth do not touch when the mouth is closed, resulting in a visible gap. While it is more common for open bites to be addressed during childhood, adults can also seek treatment to correct this condition. Fixing an open bite in adults may require a combination of orthodontic, surgical, and therapeutic interventions. This guide will provide a detailed overview of the various treatment options available for adults, the steps involved, and the factors influencing the treatment process.

Understanding Open Bite in Adults

What is an Open Bite?

An open bite is a dental condition where there is a gap between the upper and lower teeth when the mouth is closed. This can occur in the front teeth (anterior open bite) or the back teeth (posterior open bite).

Causes of Open Bite in Adults

Genetic Factors: Inherited traits such as jaw size and shape can predispose individuals to open bite.
Skeletal Discrepancies: Abnormalities in jaw growth and development.
Habits: Persistent habits like thumb sucking, tongue thrusting, or prolonged use of pacifiers during childhood.
Temporomandibular Joint (TMJ) Disorders: Conditions affecting jaw alignment and function.
Tooth Eruption Issues: Abnormal eruption patterns of teeth.

Symptoms of Open Bite in Adults

Functional Issues: Difficulty biting, chewing, and speaking properly.
Aesthetic Concerns: Facial asymmetry, protruding lips, and an extended facial appearance.
Dental Issues: Increased risk of tooth wear, temporomandibular joint disorders, and gum problems.

Treatment Options for Fixing Open Bite in Adults

Orthodontic Treatment

Orthodontic treatment is a common approach to correcting an open bite in adults. This involves the use of braces or clear aligners to gradually move the teeth into proper alignment.

Braces: Traditional metal braces or ceramic braces can effectively correct an open bite. The duration of treatment typically ranges from 18 months to 3 years, depending on the severity of the condition.
Clear Aligners (Invisalign): Clear aligners offer a discreet option for adults. The treatment duration is similar to that of braces, usually 18 months to 3 years. Aligners need to be worn for 20-22 hours per day for optimal results.

Orthognathic Surgery

For severe open bites caused by skeletal discrepancies, orthognathic surgery may be required. This surgical procedure involves realigning the jaws to correct the bite.

Pre-Surgical Orthodontics: Before surgery, patients may need to wear braces for 6 to 12 months to align the teeth in preparation for the surgery.
Surgery: The surgical procedure involves cutting and repositioning the jaws. The surgery is performed under general anesthesia and typically requires a hospital stay of 1 to 2 days.
Post-Surgical Orthodontics: After surgery, patients continue to wear braces for another 6 to 12 months to finalize the alignment of the teeth.

Myofunctional Therapy

Myofunctional therapy involves exercises designed to improve tongue posture and function, as well as strengthen the orofacial muscles. This can be a beneficial adjunct to orthodontic or surgical treatment.

Tongue Push-Ups: Place the tip of the tongue on the roof of the mouth and push upwards.
Swallowing Exercises: Practice swallowing while keeping the tongue in the correct position (against the roof of the mouth).
Lip Exercises: Strengthen the muscles around the lips to help keep them closed during swallowing.

Dental Restorations

In some cases, dental restorations such as crowns or veneers may be used to correct an open bite. This approach is typically considered when the open bite is mild and primarily due to the shape or size of the teeth rather than jaw alignment.

Crowns: Crowns can be used to increase the height of the teeth, helping to close the gap in an open bite.
Veneers: Veneers can be applied to the front teeth to improve their appearance and alignment.

Factors Influencing Treatment Choice

Severity of the Open Bite

Mild Cases: May be treated with orthodontics or dental restorations.
Moderate to Severe Cases: Often require a combination of orthodontics and surgery.

Age of the Patient

Younger Adults: May have more flexible bones and respond better to orthodontic treatment alone.
Older Adults: May require surgical intervention in addition to orthodontic treatment due to less flexible bone structures.

Patient’s Overall Health

Good Health: Candidates for surgery should be in overall good health to minimize risks and complications.
Health Conditions: Certain medical conditions may preclude surgical options, necessitating alternative treatments.

Patient’s Lifestyle and Preferences

Lifestyle: Clear aligners may be preferred by adults who want a discreet treatment option.
Preferences: Some patients may prefer non-surgical options and opt for longer orthodontic treatment instead.

Steps in the Treatment Process

1. Initial Consultation

Comprehensive Evaluation: A dentist or orthodontist will perform a thorough evaluation, including dental X-rays, photographs, and impressions of the teeth.
Treatment Plan: Based on the evaluation, a personalized treatment plan will be developed.

2. Orthodontic Treatment

Braces or Aligners: Placement of braces or fitting for clear aligners.
Regular Adjustments: Monthly or bi-monthly visits to adjust braces or receive new sets of aligners.

3. Surgical Intervention (if needed)

Pre-Surgical Orthodontics: Wearing braces to align teeth before surgery.
Orthognathic Surgery: The surgical procedure to reposition the jaws.
Post-Surgical Orthodontics: Continuing orthodontic treatment to finalize tooth alignment.

4. Myofunctional Therapy (if recommended)

Exercises: Regularly performing prescribed exercises to improve tongue posture and muscle function.

5. Post-Treatment Care

Retention: Wearing retainers to maintain the new position of the teeth and prevent relapse.
Follow-Up Visits: Regular check-ups to monitor the stability of the results.

Common Questions about Fixing Open Bite in Adults

How Long Does It Take to Fix an Open Bite in Adults?

The time required to fix an open bite in adults varies based on the severity of the condition and the chosen treatment method. Orthodontic treatment typically takes 18 months to 3 years. Surgical treatment may extend the duration to 2 to 3 years, including pre- and post-surgical orthodontics.

Can Adults Avoid Surgery for Open Bite?

Yes, adults with mild to moderate open bites may avoid surgery through orthodontic treatment and myofunctional therapy. However, severe cases often require surgical intervention to achieve optimal results.

Is Treatment for Open Bite in Adults Painful?

Orthodontic treatment may cause mild discomfort, especially after adjustments or when switching to new aligners. Orthognathic surgery involves a more significant recovery period with some pain and swelling, but pain management options are available to ensure patient comfort.

How Effective is Orthodontic Treatment for Adults?

Orthodontic treatment is highly effective for adults, especially when combined with other therapies like myofunctional exercises. While treatment may take longer than in children, adults can achieve significant improvements in bite alignment and overall oral health.

What Are the Risks of Orthognathic Surgery?

Orthognathic surgery, like any surgical procedure, carries risks such as infection, bleeding, and complications related to anesthesia. However, it is generally considered safe, and most patients recover without serious issues. A thorough evaluation and consultation with an oral and maxillofacial surgeon can help assess individual risks.

Conclusion

Fixing an open bite in adults is a feasible goal with the right combination of orthodontic, surgical, and therapeutic interventions. The treatment process can be lengthy, ranging from 18 months to 3 years, depending on the severity of the condition and the chosen approach. Adults should consult with a dental professional to develop a personalized treatment plan that addresses their specific needs and goals. With commitment and proper care, adults can achieve a corrected bite, improved function, and enhanced aesthetics, leading to better oral health and overall well-being.
