An overbite refers to the vertical overlap of the upper front teeth over the lower front teeth when the mouth is closed. A small overlap is completely normal and even healthy. However, when the upper teeth excessively cover the lower teeth, this is considered a deep overbite or deep bite. In more complex cases, it may be linked to Class II malocclusion, especially when the upper jaw sits too far forward relative to the lower jaw. An excessive overbite can affect chewing, jaw comfort, tooth wear and long-term oral health.

The most common causes of an overbite include genetics, jaw growth imbalance and childhood habits. If parents have a deep bite or Class II malocclusion, children may inherit similar jaw patterns. Other contributing factors include prolonged thumb sucking, extended pacifier use, tongue thrusting, teeth grinding (bruxism), and missing teeth. In some cases, the issue is dental (tooth position), while in others it is skeletal (jaw structure).

Yes, an overbite can be genetic. Jaw size, facial structure and bite alignment are strongly influenced by heredity. If one or both parents have a deep overbite or jaw misalignment, their child may be more likely to develop a similar bite pattern. While genetics play a major role, early orthodontic evaluation can help guide jaw development and reduce severity.

A mild overbite is normal. However, a severe overbite can lead to enamel wear, tooth fractures, gum recession and jaw strain. When the lower teeth contact the roof of the mouth or sit under excessive pressure, long-term damage may occur. Correcting an overbite helps protect teeth from uneven wear and reduces the risk of restorative dental work later.

Yes. Braces for overbite correction are one of the most effective treatment options. Braces gradually reposition the teeth and adjust the vertical overlap using specialised mechanics, bite opening plates and elastics. They are suitable for mild, moderate and even severe overbites. Treatment duration varies depending on complexity, but braces provide predictable and long-lasting results.

Clear aligners like Invisalign or Hugo Aligners can correct a mild to moderate overbite, particularly when the problem is tooth-related rather than skeletal. Aligners gradually shift teeth into better alignment through a customised treatment plan. However, severe skeletal overbites may require braces or surgical correction. Consistent wear — typically 20–22 hours per day — is essential for success.

Not always. Many patients assume that overbite surgery is necessary, but most cases can be corrected with orthodontic treatment alone. Surgery (orthognathic surgery) is generally reserved for severe skeletal discrepancies in adults where the jaw position significantly contributes to the deep bite. An orthodontic consultation determines whether surgery is required.

A deep bite is another term for a severe overbite. It occurs when the upper front teeth excessively cover the lower front teeth, sometimes completely hiding them when the mouth is closed. Deep bites can increase the risk of tooth wear, gum damage and jaw discomfort. Orthodontic treatment can effectively reduce the vertical overlap.

Yes, an untreated overbite can worsen over time. As enamel wears down and teeth shift naturally with age, the bite may deepen further. Teeth grinding can accelerate this process. Early intervention helps prevent progressive damage and reduces the risk of long-term complications.

Orthodontists recommend children have their first evaluation around age seven. Treating an overbite in children during growth allows for jaw guidance and simpler correction. However, adult overbite treatment is also highly effective. While jaw growth is complete in adults, orthodontic techniques can still achieve excellent functional and cosmetic results.

The length of overbite correction depends on severity. Mild cases may take 15–18 months, while more complex cases can take 18–24 months or longer. Surgical cases require additional time for preparation and recovery. Your orthodontist will provide a personalised treatment timeline during consultation.

Yes. A severe overbite can place stress on the jaw joints, potentially contributing to temporomandibular joint (TMJ) disorders. Symptoms may include jaw clicking, popping, stiffness, headaches or facial pain. Correcting bite alignment often reduces strain on the joints and improves comfort.

In some cases, yes. A pronounced overbite may create a more convex facial profile or make the chin appear recessed. Correcting jaw and tooth alignment can improve facial balance and symmetry, often enhancing confidence as well as function.

Yes, a severe overbite may influence tongue placement and sound production, potentially causing speech difficulties. While mild cases may not affect speech, significant vertical overlap can interfere with articulation. Orthodontic treatment often improves speech clarity when bite alignment is corrected.

An untreated overbite can lead to enamel erosion, tooth fractures, gum recession, jaw strain and headaches. Over time, uneven bite forces may require restorative treatments such as crowns or bonding. Early orthodontic correction prevents avoidable damage and protects long-term oral health.

Orthodontic treatment involves mild pressure as teeth shift into alignment. Patients may experience temporary discomfort after adjustments, but this usually resolves within a few days. Modern orthodontics prioritises patient comfort and uses advanced techniques to minimise pain.

The cost of overbite treatment varies depending on severity, treatment type and duration. Braces and clear aligners differ in cost, and surgical cases involve additional hospital expenses. Many orthodontic practices offer payment plans to make treatment accessible. A consultation provides an accurate cost estimate tailored to your needs.

Yes. Chronic grinding (bruxism) can wear down enamel and deepen an existing overbite over time. If you grind your teeth, your orthodontist may recommend a night guard in addition to bite correction treatment.

Signs of an overbite in children include upper teeth excessively covering lower teeth, difficulty chewing or speech concerns. In severe cases, lower teeth may contact the roof of the mouth. An early orthodontic assessment helps determine whether treatment is needed.

Look for an experienced orthodontist who provides comprehensive diagnostics, digital imaging and personalised treatment plans. Ask about experience treating deep bites and Class II malocclusion. A thorough consultation ensures the most predictable and effective treatment outcome.
