Here I am with the Hulk and his teeth look better mine! Dental Arts was on Fourth Avenue but they moved to 154 West 14th Street and after all these years I do see Alexander Duka who is a good dentist.
I got my teeth cleaned and because of acid reflux to protect my gums I was urged to start using tooth paste, mouth wash and even a paste to massage on my gum line to protect against erosion from the acid.
I bought the paste directly from Duka and it is called "GC MI Past Plus" http://sale.dentist.net/products/gc-america-mi-paste
After 9-11 I developed acid reflux and other health issues but even worse health conditions have arisen from traumatic events after 9-11.
