Treatment for Overbite

An overbite, a prevalent dental issue, occurs when your teeth fail to align properly. It often begins in early childhood due to habits like thumb sucking, pressing the tongue against the teeth, or prolonged pacifier use. Narrowing of the dental arch and palate can lead to the lower jaw shifting backward, causing the upper teeth to overlap it. Overbites can also develop in individuals who lose their back teeth, particularly molars. While treatment for overbites typically occurs between ages 10 to 12, individuals of any age with an overbite can and should seek treatment.

Steps

At-Home Overbite Diagnosis

Close your mouth naturally. Allow your teeth to come together naturally while keeping your jaw relaxed, without exerting pressure to force them together. This allows your teeth to settle into their natural positions, helping you determine if your upper teeth overlap your lower jaw.

Avoid forcing your teeth together, as this may yield inaccurate results.

Assess Your Smile in the Mirror. To self-diagnose an overbite, use a mirror to examine your teeth. Stand in front of the mirror, smile, and observe your teeth.

Position yourself close to the mirror and smile, pulling your lips away from your teeth.
Check if your upper teeth extend over your lower front teeth.
If your upper teeth significantly overlap the lower ones (more than 3.5 mm), you likely have an overbite.
You might also notice your lower teeth biting near or into the roof of your mouth.

Determine the Type of Overbite. Malocclusion occurs when teeth don't align properly, categorized into overbites and underbites.

Class 1 is the most common, where the upper teeth overlap the lower teeth but the bite is otherwise normal.
Class 2 involves significant overlap of the upper teeth over the lower ones, often with a receded chin.
Class 3, or underbite, is characterized by the lower jaw protruding, causing the lower teeth to overlap the upper teeth.

Consult a Dentist. If self-testing suggests an overbite, see a dentist for confirmation during a routine checkup.

Untreated overbites can lead to headaches, tooth decay, speech problems, mouth breathing, chewing difficulties, and even TMJ disorders affecting posture.

Professional Overbite Diagnosis

Visit a Dentist Regularly. Regular dental checkups, ideally twice a year, can address dental issues like overbites. If you experience discomfort, your dentist can diagnose and treat the problem.

Approximately 46% of children and nearly 30% of adults may have overbites, making early diagnosis crucial for effective treatment and prevention of complications.

Schedule a dental examination. A routine dental checkup involves an assessment by a dental hygienist followed by a consultation with the dentist.

The dentist will inspect your teeth during the exam to determine if you have an overbite.

Agree to an X-ray. While a visual inspection can often diagnose an overbite, your dentist might recommend dental X-rays to examine your jaw and teeth, especially in children with emerging permanent teeth.

X-rays help diagnose tooth positioning and detect dental issues or damage.
If any problems are identified, such as cavities, your dentist will discuss treatment options.

Seek advice from an orthodontist. Upon confirmation of an overbite, your dentist may refer you to an orthodontist, who specializes in realigning teeth.

Orthodontists undergo additional training compared to dentists and focus on correcting misalignments like overbites.
Your consultation with the orthodontist will include discussions about treatment options to correct the overbite.
Treating an overbite is crucial for oral health as it reduces the risk of tooth decay, gingivitis, and relieves strain on the teeth, jaws, and muscles.

Treatment for Overbite

Consider braces. Braces are a common treatment for childhood overbites, gradually realigning teeth by applying pressure and guiding them into proper position.

Braces comprise metal brackets and archwires affixed to the teeth, held in place with elastic bands.
Initial discomfort and irritation from braces typically subside within two weeks.

Consider aligners. Aligners offer an alternative for correcting overbites, functioning similarly to retainers by fitting snugly over the teeth.

These invisible, acrylic molds are removable for eating and brushing, making them a preferred choice for some individuals.
Since aligners are custom-made, they are typically recommended for teens and adults rather than children.

Discuss the possibility of tooth extraction. Overcrowding may lead to overbites, requiring tooth extraction to alleviate the issue.

Tooth extraction involves removing a tooth from its socket within the bone, often with the aid of x-rays and anesthesia.
There are two types of dental extractions:
- Simple extraction involves loosening the tooth with an elevator instrument before using forceps to remove it.
- Surgical extraction may involve making an incision in the gum and possibly cutting the bone to facilitate tooth removal, often performed under anesthesia.

Explore teeth repair options. Overbites can strain the jaw and muscles, leading to teeth grinding and potential damage.

Your dentist can address this issue by capping damaged teeth or providing a nighttime mouth guard.
Alternatively, a TENS machine can help stop teeth grinding by delivering impulses to relax the jaw muscles when tension is detected.

Inquire about surgical options. Oral surgery becomes necessary when orthodontic treatments like braces or aligners fail to correct the overbite.

Horizontal maxillary protrusion surgery involves moving the jaw to correct the overbite.

Insights

To alleviate initial discomfort from braces, consider using wax to cover any sharp edges or taking over-the-counter pain relievers like Tylenol or ibuprofen.
Functional appliances, such as twin plates, may be necessary to aid in correcting an overbite.
If you have concerns about your teeth or jaw, schedule a visit to your dentist for evaluation.

Cautions

Be cautious not to mistake this condition for buckteeth, where the upper teeth protrude despite jaw alignment.
Consider seeking a second opinion if your dentist suggests corrective surgery.

Frequently Asked Questions

What are the common causes of an overbite in children?

Common causes of an overbite in children include habits such as thumb sucking, prolonged pacifier use, and pressing the tongue against the teeth. Additionally, a narrowing dental arch can contribute to misalignment.

How can I self-diagnose an overbite at home effectively?

To self-diagnose an overbite, close your mouth naturally and assess if your upper teeth overlap your lower teeth significantly. Use a mirror to check if your upper teeth extend over the lower ones by more than mm.

What treatment options are available for correcting an overbite?

Treatment options for correcting an overbite include braces, which realign teeth gradually, and aligners, which are removable and invisible. In some cases, tooth extraction or surgery may be necessary.

How often should I visit the dentist for overbite evaluation?

It is recommended to visit the dentist at least twice a year for routine checkups. Regular evaluations help identify and address dental issues, including overbites, before they lead to complications.

What are the potential complications of untreated overbites?

Untreated overbites can lead to several complications, including headaches, tooth decay, speech difficulties, and TMJ disorders. Addressing an overbite is essential for maintaining overall oral health.
