My son had white spots on his teeth due to lack of calcium. A dentist from my city told me that he need a procedure with a drill to remove it. My mom who lives in Whittier recommended Dr. Gutierrez. This dentist removed the stain the same day with a different procedure very nicely done with no pain. Now my son is smiling again. I really recommend Dr. Gutierrez for his professionalism and care and also his staff. I was impressed for the modern equipment he uses in his office.
