A dental brush having a flexible fibrous tip with internal cannula to allow medicament, such as tetracycline, chlorhexidine or stannous fluoride, or combinations thereof to flow through the fibrous tip. The flexible fibrous tip includes a nonwoven tufted surface that completely covers the tip to remove plaque. The applicator tip fits between the teeth and the gum line and delivers both physical and chemical treatment to interproximal periodontal pockets. The medicament solution is stored in a disposable sealed and sterile cartridge and is held in the base of the device. A pump built into the base provides pressure to push the medicament through the cannula to the fibrous brush tip to provide site-specific dosage-controlled treatment. The brush tip is disposable and provides effective interproximal subgingival debridement and site-specific application of medication to infected areas.
