Causes and Treatment Options

A deep bite occurs when the upper front teeth excessively overlap the lower teeth when the mouth is closed. Normally, a slight overlap of about 1-2 mm is considered ideal, but when the overlap exceeds 2-4 mm, it can affect both dental function and appearance.

Since deep bites vary in severity, an orthodontic evaluation is essential to determine the best treatment plan. Some cases are mild, while others may indicate underlying dental issues that need specialized care. Treatment options include braces, clear aligners, tooth extractions, and jaw correction surgeries.

Symptoms of a Deep Bite

If you suspect you have a deep bite, here are some common signs to look out for:

  1. Excessive wear and tear of lower teeth – Cracks, lines, or chipping in the lower front teeth.
  2. Chewing difficulties –Trouble biting or discomfort while eating.
  3. Tooth chipping and sensitivity – Increased wear on both upper and lower teeth.
  4. Gum issues –Receding gums, bad breath, and a higher risk of gum infections.
  5. Jaw pain and headaches – Due to misalignment and uneven pressure on the teeth.
  6. Mouth ulcers and sores – Caused by teeth repeatedly hitting the soft tissues of the mouth.
  7. Speech difficulties – Some individuals may develop a slight lisp or pronunciation issues.

Ignoring a deep bite can lead to tooth decay, gum disease, and long-term jaw complications, making early intervention crucial.

Causes of a Deep Bite

Deep bites can develop due to various factors, including:

  1. Genetics – Some people are born with a natural jaw structure that leads to deep bites.
  2. Tooth size discrepancy – If the upper teeth are larger than the lower ones, it can cause excessive overlap.
  3. Thumb sucking and tongue thrusting – Habits that affect normal tooth alignment.
  4. Tooth loss – Missing teeth can lead to shifting and bite misalignment.
  5. Jaw positioning issues – Certain jaw structures create a deep bite over time.
