I have always been the type of person that takes care of my teeth as fat as brushing, flossing, etc. But due to me taking medication my teeth wasn't as white as I wanted to be thru the years. So I didn't to get the Zoom treatment prior to the treatment. My dentist gave a fluoride toothpaste to toughen my gums. Which worked good . I went to my Denist office for my Appt that morning and the dental assistant prepped me for the procedure and protected my gums and outer mouth and put a protective seal on my lips and protective glasses on my eyes. I was to have 4 (15) minute sessions. I had read reviews prior and their were good and bad reviews. So before we started I closed my eyes and prayed that I would have no pain during the procedure and that everything would be ok. Well sure enough I was fine during the 4 (15) sessions no problems matter of fact I went to sleep :) BUT 9 hours later once I was going on about my life I was out with my older children at a movie and the Dental Demons dropped the nuclear bombs on me in the movie theater I sat happy that my teeth were pearly white the Psin began it felt like I was walking Naked in the Artic with shoes made of razor blades on my feet where in the HECK did this pIn come from 1,2,3 sharp pains with a cold sensation glows thru my mouth I wanted to jump up and take off running. With my traction of course my children were worried and others around me looking at me like I had escaped the mental ward floor number 10! But I couldn't help it I thought Lord take me on having babies felt much better than the sensation I was having. The flow of pain happened 3-4 in that hour and stopped then a couple hours later once home the streams of pain came back, I immediately called my Dental office after hours number and he called me in some pain meds. Now 2 days later I still have small tremors in my mouth and my jaw tissue on the right side is swollen. So I said that to say Beauty is Pain even a Rose can grow from the cracks of concrete, I love the way my teeth look but did not like the after shocks to say the least. Everyone has their own pain level, so it's up to the individual to decide of it is worth it to try the Zoom treatment.
