Understanding Bite Misalignment: Overbite, Underbite, Crossbite and Open Bite

Artistree Dental and Cosmetic Clinic · Gurugram · Updated 2026-10-11

If you have noticed that your upper and lower teeth do not meet evenly, or that your jaw feels off when you bite down, you may be dealing with a form of bite misalignment. This is a common concern among patients in Gurugram, and understanding the type you have is the first step before deciding on treatment.

What Is Bite Misalignment (Malocclusion)?

Bite misalignment, known medically as malocclusion, refers to how the upper and lower teeth fit together when the jaw is closed. In an ideal bite, the upper teeth sit slightly over the lower teeth and line up comfortably. When this alignment is off, it can affect chewing, speech, jaw comfort and the appearance of your smile.

Common Types of Bite Misalignment

Overbite

An overbite happens when the upper front teeth extend noticeably over the lower front teeth. A small amount of overlap is normal, but an excessive overbite can cause the lower teeth to bite into the roof of the mouth or gums, leading to discomfort over time.

Underbite

An underbite is the opposite condition, where the lower teeth and jaw extend further forward than the upper teeth. This can make the chin appear more prominent and may affect chewing efficiency and jaw joint comfort.

Crossbite

A crossbite occurs when some upper teeth sit inside the lower teeth instead of outside, either on one side (unilateral) or both sides (bilateral). This can cause uneven wear, gum recession in certain areas, and sometimes a visible shift of the jaw to one side.

Open Bite

An open bite is when the upper and lower front teeth do not touch at all when the jaw is closed, leaving a visible gap. This can affect speech clarity and make it harder to bite into certain foods properly.

What Causes These Bite Problems?

• Genetics and jaw bone size inherited from parents
• Childhood habits such as prolonged thumb sucking or pacifier use
• Tongue thrusting or improper tongue posture during swallowing
• Early loss of baby teeth or delayed loss affecting permanent tooth position
• Injury or trauma to the jaw
• Mouth breathing habits, often linked to blocked nasal passages

Signs You Might Have a Misaligned Bite

• Difficulty biting or chewing certain foods comfortably
• Frequent jaw clicking, soreness or fatigue
• Speech that sounds slightly off, such as a lisp
• Uneven or accelerated wear on certain teeth
• Visible gaps, crowding or an asymmetrical smile
• Breathing through the mouth frequently, especially at night

Treatment Options Available at Artistree

At Artistree Dental and Cosmetic Clinic in Mayfield Garden, treatment is planned based on the type and severity of your bite issue, your age, and your oral health goals. Common approaches include:

• Clear aligners or braces: Gradually guide teeth into better alignment for many mild to moderate cases
• Fixed orthodontic appliances: Used for more complex misalignments requiring greater control over tooth movement
• Interceptive orthodontics for children: Early guidance to manage jaw growth and developing bite issues
• Restorative support: In some cases, crowns or bite adjustments help balance how teeth meet
• Referral for jaw surgery: For select severe skeletal cases, co-managed with oral and maxillofacial specialists

Your dentist will first assess your bite with a clinical examination and, when needed, X-rays, before recommending a realistic treatment path.

When Should You See an Orthodontist?

If you notice jaw discomfort, visible gaps between your front teeth, or difficulty chewing comfortably, it is worth getting a professional opinion rather than waiting. Early assessment, especially for growing children, often allows for simpler and shorter treatment later on.
