Everything about Overbite: Causes, Types, and Treatments

What is an Overbite?

When the jaws are closed, an overbite, sometimes called a deep bite, occurs where the upper front teeth overlap the lower front teeth. The upper and lower teeth stray out of alignment, affecting how you chew, speak, and look. It is a relatively regular dental issue that can be resolved with orthodontic treatment or, in more extreme circumstances, with surgical intervention.

Types of Overbites:

  • Vertical Overbite: The most common type, where the upper teeth significantly overlap the lower teeth vertically.
  • Horizontal Overbite (Overjet): While not precisely an overbite, this occurs when the upper front teeth project horizontally beyond the lower front teeth.
  • Open bites In this case, the upper and lower front teeth do not come in touch when the jaws are closed, leaving a gap.
  • Deep Bite: A severe overbite where the upper front teeth excessively cover the lower front teeth, often leading to enamel wear and jaw discomfort

Causes of Overbite:

Overbites can develop due to several circumstances, including:

  • Genetics: The tendency to develop an overbite may be strongly influenced by family history.
  • Long-term habits like thumb sucking and pacifier use might cause the teeth and jaw to develop incorrectly.
  • Malocclusion: This includes dental misalignments and anomalies in jaw size.
  • Skeletal Imbalances: An overbite may result from irregular upper or lower jaw growth.
  • Tongue Thrusting: The location of the teeth and jaw can be impacted by incorrect tongue posture, size and function.

Effects of Overbite:

1. Dental Issues: An overbite might eventually result in dental issues such as tooth wear, chipping, or fracture. The front teeth may become worn down or destroyed under too much pressure.

2. Misaligned Teeth: An overbite can result in misaligned teeth, crooked and crowded teeth. The degree of tooth decay and gum problems may increase due to this misalignment, as it poses difficulties in maintaining oral hygiene.

3. Temporomandibular joint (TMJ) disorders: Overbites may be a factor in TMJ issues. When the bite is out of alignment, the jaw joints are under stress, which can cause pain, discomfort, jaw clicking, and restricted jaw movement.

4. Articulation and Pronunciation Issues: Severe overbites might affect speech by posing articulation and pronunciation issues. A lisp or other speech difficulties may result from this.

5. Problems with Self-Esteem: Overbites can impact one's looks and cause self-consciousness or low self-esteem. People could feel self-conscious when they grin or be reluctant to expose their teeth when speaking or smiling.

6. Digestive Issues: An overbite can sometimes make it difficult to chew food, which might result in digestive problems. Larger food particles entering the digestive tract as a result of improper chewing might have an impact on digestion and nutritional absorption.

7. Breathing Issues: Severe overbites may exacerbate breathing issues like snoring or sleep apnea. Breathing obstruction during sleep may result from the jaws and teeth being out of position.

Overbite Treatment Options:

1. Braces: To treat overbites, traditional braces are frequently utilized. They apply continual pressure to move the teeth into the proper position gradually.

2. Clear Aligners: These transparent, removable clear aligners can also be utilized to fix overbites. The custom-made Illusion Aligners are changed every few weeks as the teeth gradually realign.

3. Functional appliances: By encouraging healthy jaw development and posture, these removable appliances are generally utilized in children and teenagers to treat overbites.

4. Headgear: Headgear may occasionally be worn in addition to braces to address severe overbites. It controls the development of the jaw and teeth by applying external pressure.

5. Jaw surgery: Orthognathic surgery may be advised in extreme cases if a jaw misalignment brings on the overbite. The jaws are moved during this procedure to enhance the site's functionality and appearance.

Overbite Treatment Cost in India:

The price of overbite therapy in India may differ depending on the extent of the malocclusion, the selected course of treatment, and the region. Orthodontic treatment might cost anywhere from a few thousand to several lakh rupees. Surgical procedures are more expensive if they are required.
