I just wanted to report back.
Thanks to some important info given to me by momof1cutie
I knew the questions to ask when I saw my periodontist again. It turns out that antibiotic is usually a secondary line of defense against gum disease...scaling and planing being the first.
When I presented this research to my periodontist, she admitted to me that she prefers to do it that way (using antibiotics as a secondary method) but the dental office prefers to offer antibiotics along with scaling and planing.
I won't even get started about my opinions about why that may be
Momto1cutie pointed out to me in a pm that gum disease needs to be taken seriously, especially so for pregnant women or women who might become pregnant.
I researched her claim and found this:http://www.perio.org/consumer/mbc.baby.htm
I also found research that confirms that scaling and planing statistically has great success in helping pregnant moms with gum disease carry their babies to term:http://www.perio.org/consumer/pregnancy-news.htm
(This article also points out that use of the antibiotic has little effect)
Thank you so much Momto1cutie! Thought I would spread the wealth of info!
P.S. Got my scaling and planing done yesterday with no Arestin therapy. Now I go back in a month to see how I've healed...I'll report back then too.
