DR.Arun

“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.”

We are not patients of Plaza, but they really helped us out in an emergency situation. I called minutes before they were closing for the day on a Friday, but they were extremely helpful and willing to see my daughter after closing time to help fix a broken bracket and stray wire right before a holiday weekend. They were friendly and kind and did a great job!
