but of course I don't. I have my share of fillings and crowns. I didn't take care of my teeth as much as I should have. When I came here in the United States that's when I learn the importance of cleaning your teeth but it was too late. I have to have a lot of work done to my teeth. The worse is a crown. It was not only painful but very expensive. When I went to the dentist they put a temporary crown which keeps coming out. It was irritating because the tooth was painful already and if the crown keeps coming out it is more painful especially when food gets in there. If I knew about Dentemp OS it would have my those days a lot easier for me. Dentemp OS provides fast and temporary relief and discomfort when you need it the most.
