Oral habits refer to repetitive behaviors involving the mouth that can affect dental health and development. Common examples include thumb sucking, nail biting, and lip biting. These habits can lead to issues such as misaligned teeth, changes in jaw structure, and increased risk of cavities. Many children engage in oral habits as a form of self-soothing or stress relief. While some habits may resolve on their own, persistent behaviors may require intervention from a dentist or orthodontist. Addressing these habits early can help prevent long-term dental problems and promote healthier oral development.
