Arestin Microspheres

What is Arestin

Although scaling and root planing is effective at reducing plaque and some bacteria, it doesn’t kill all of the bacteria that cause periodontal disease. It is a mechanical procedure and the instruments used to perform scaling and root planing cannot always reach the bacteria that reside at the bottom of deep or difficult-to-reach periodontal pockets. For these pockets, Dr Longbottom may use perioscopy and/or add a locally administered antibiotic called ARESTIN®, which helps kill the harmful bacteria that cause periodontal disease-so that the infection becomes more easily managed and won’t immediately return.


ARESTIN® is a small amount of powder that contains “Microspheres” – tiny, bead-like particles that are smaller than grains of sand and are not visible to the eye. The Microspheres are filled with an antibiotic, and they release the drug over time into the infected periodontal pocket, killing the bacteria that causes periodontal disease.

  • Dr Longbottom has found that applying ARESTIN® during scaling and root planing assists in shrinking the size of infected periodontal pockets, killing the bacteria associated with periodontal disease, and reducing bleeding on probing of the gums.
  • ARESTIN® remains in the pocket for up to 21 days—to help ensure continued treatment.
  • ARESTIN® is safe and easy for Dr Longbottom to administer.
