We moved from Houston to Austin about 9 years ago and I went looking for another dentist here. I found one and they recommended scaling after doing the gum measurements and finding some were 4 etc. They also put the little tablets in my gums. At that point they wanted me to come back every three months and the charges were racking up. I went back to my old dentist in Houston and they did the same measurements about six months later and I think I had a few 3s and they just cleaned. Since then I've been driving back to Houston for my 6 month cleaning and I think once they found some 4s and did a "deep clean/scale" but usually its just the regular cleaning. The one time they had to do the deep was still fairly inexpensive. I went in January of this year and again nothing was wrong, they just told me to floss more, but then traveled a lot and finally went back last week (so well delayed at 11 months). In that time I understand the practice was sold to another company. This time I got my exam and xrays (I've never had a cavity and just turned 50) and the hygenist did the poking gum routine and said she found a few 4s and one 5 at which point she made me sign several new forms about having early periodontal disease and told me that I would need to be back every 3 months. She then sent me out to talk to their billing person who printed out all I needed that day and a follow up a month later - $377 that day which included $50 for Prevident 5000 and $50 for Chlorhexidine (found out later they were toothpaste and wash). I have Safeguard so normally I get out with a small co-pay. It didn't seem like the scaling took any longer than a normal clean, but now I am supposed to go back for "gingival irrigation and the regularly scheduled prophylaxis" next month for another $130. I'm a little suspicious at the addition of the pricey toothpaste and mouthwash. I've had this scaling etc done before and I assumed the few pockets I had this time (which were a couple 4s, one 5 and the rest normal just as they have been some times in the past) were probably due to me not being in for 11 months. Should I be wary of this office now?
