It also is used after rooting and planning procedures for adult periodontitis.

Its safety and efficacy has not been established for patients with acute necrotizing ulcerating gingivitis (ANUG).

SIDE EFFECTS: Side effects of chlorhexidine include:

  • staining of the teeth and other oral areas,
  • dental tartar (dental calculus),
  • altered sense of taste,
  • toothache, and
  • oral mucosal irritation.

Cases of parotid gland swelling and inflammation of the salivary glands (sialadenitis) have been reported.
