Dr. Arun Feature

"Orthodontics is a dental specialty that is concerned with the study and treatment of malocclusions (improper bites), which may be a result of tooth irregularity, disproportionate jaw relationships, or both. My passion for being an orthodontist and creating artistic smiles is amazingly rewarding as the result of orthodontic treatment restores confidence and self-esteem."
