In pediatric dentistry, oral habits are repetitive actions involving the mouth that can impact a child's dental and skeletal development. While many are normal self-soothing behaviors in infancy, they are considered deleterious if they persist beyond age three or four. Common Oral Habits Thumb or Digit Sucking: The most prevalent habit; it can push front teeth outward and cause misalignment. Mouth Breathing: Often caused by nasal obstructions (like enlarged adenoids), it can lead to a long, narrow face and a high palatal vault. Tongue Thrusting: An abnormal tongue position during swallowing that often results in an 'open bite' where front teeth do not meet. Bruxism: Involuntary grinding or clenching of teeth, which can lead to tooth wear, headaches, and jaw pain. Nail Biting: Often a sign of stress; it can cause tooth crowding or damage to the incisal edges of teeth. Lip Biting/Sucking: Frequently involves the lower lip and can contribute to protruding upper teeth.
