I went for a cleaning today and have very bad periodontitis, the dentist gave me a couple of treatments, I only needed one treatment, 1600 dollars, is that right?

Periodontitis doesn't require a very complicated treatment, if the tooth itself is fine, only cleaning and anti-inflammatory, don't need so much money. The main factor that triggers periodontitis is tartar, and if the scaling is handled well and a little mouthwash is used, the price is within 200 dollars. But periodontitis is a recurrent disease, an anti-inflammatory and can not solve the problem at all to maintain good habits.
