As of 2015, the cost for a dental deep cleaning is potentially $140 to $210, reports the Consumer Guide to Dentistry. A dental deep cleaning is a form of treatment for gingivitis and periodontitis or a form of prevention of these diseases.
As part of a strategy to treat periodontitis, dental deep cleaning may entail multiple procedures called scaling and root planning, reports the Consumer Guide to Dentistry. These procedures involve removing tartar and plaque from periodontal pockets within the gums and around teeth. The technology used during procedures, patient insurance type, the number of professionals involved in the procedures, the frequency of treatment and the dentist's location affect costs.
