Her goal is to make her patients realise the importance of oral health and help them prevent oral diseases and manage appropriately with the help of their oral health practitioners.

Prosthodontics is about giving patients a better smile and function. When treatment is completed, Arthi's patients show genuine happiness with a real smile, which gives tremendous job satisfaction to her. Arthi believes everyone deserves a better and brighter smile and she makes every possible effort to give the best option available to her patients.
