(Pocket Depth Reduction)


What to Expect

Prior to Procedure

  • Tell your dentist of any recent changes to your health, medications, allergies, or supplements.
  • Take your prescription medications, unless your dentist says otherwise.
  • Talk to your dentist or pharmacist if you are taking more than one drug. Some drugs can be dangerous when mixed. This includes over-the-counter medications and herb or dietary supplements.
  • You may be asked to take an antibiotic before surgery.
  • Arrange for a ride if you are having sedation.
Sometimes, sedative medications are used to make you more relaxed during surgery. If you are undergoing conscious sedation, you will be asked to not eat for at least 6 hours before surgery. Otherwise, you can follow a normal diet.


A local anesthetic will be used near the gum disease.
Your dentist may recommend conscious sedation. You will be awake, but will have no anxiety during the surgery.

Description of Procedure

This surgery is usually done in an outpatient setting. You do not need to stay overnight. If you are undergoing sedation, you will have it through an IV. Your heart rate, blood pressure, and breathing will be monitored during and after the surgery.
The periodontist or dentist will numb the affected area using a local anesthetic delivered through a needle. They will make a small cut in the gum line near the tooth root. The gum flap will be pulled back, and he will clean out and scrape the infected area. The gum flap will be repositioned to minimize the deep pocket size that formed. The gum will be stitched back into place. A dressing will be applied.

How Long Will It Take?

The time it takes to complete the procedure depends on how bad the damage is and how many gum areas are affected.

How Much Will It Hurt?

Anesthesia will prevent pain during surgery. Pain and discomfort after the procedure can be managed with medications.
