Gerald Vinduska

Dr. Jerry greatly appreciates the opportunity to provide dental disease treatment to his patients at such affordable fees.

“Eating is one of life’s most enjoyable things. Unfortunately, every human being is vulnerable to the insidious bacterial diseases of tooth decay and adult gum disease, which often leads to total tooth loss and the accompanying loss of critical facial bony features. Neglecting teeth by not brushing thoroughly and flossing every day leads to the painful and expensive realization of the seriousness of tooth decay and gum disease. Visit a good dentist at least once a year to avoid painful and expensive loss of molars, premolars, canines and incisors.”
