When gum disease becomes more advanced, simply cleaning the teeth may not be enough. In these cases, we may recommend Arestin®—a powerful, targeted antibiotic placed directly into the infected gum pockets to fight the bacteria causing inflammation and bone loss.
What Is Arestin?
Arestin is a locally administered antibiotic that works alongside scaling and root planing (SRP) to treat periodontal disease. It contains minocycline, an antibiotic that’s delivered in tiny microspheres placed gently beneath the gumline right where the infection lives. Unlike antibiotics you take by mouth, Arestin goes straight to the source, delivering high concentrations of medication directly into the periodontal pockets without affecting the rest of your body.
Why Arestin?
When your gums pull away from the teeth, bacteria can collect deep below the surface. Even after deep cleaning, some bacteria may remain. Arestin:
- Targets bacteria where brushes and floss can’t reach
- May Reduce pocket depth more effectively than SRP alone
- Supports the healing of gum tissue
- Continues to fight infection for up to 21 days after placement
What to Expect During Treatment
- Arestin is placed immediately after deep cleaning (scaling and root planing).
- The application is quick and painless, requiring no numbing or needles.
- The antibiotic microspheres gradually dissolve on their own—no removal needed.
- Most patients return to their normal activities immediately after the visit.
Keeping Your Gums Healthy Long-Term
Arestin is one of many tools we use to help preserve your natural teeth and restore gum health. When used at the right time, it can make a meaningful difference in stopping periodontal disease from progressing.
