Periodontal Deep Cleaning Below the Gumline
When tartar has settled below the gums, a regular cleaning cannot reach it. A deep cleaning goes where the problem is.
Understanding the service
What periodontal deep cleaning involves
Periodontal deep cleaning, often called scaling and root planing, removes plaque and tartar from the root surfaces beneath the gumline. It is recommended when gums have pulled away from teeth and formed pockets where bacteria collect.
Smoothing the root surfaces makes it harder for bacteria to reattach and gives gum tissue a chance to tighten back around the teeth. It is one of the most common first steps in treating gum disease.

Step by step
How a deep cleaning is typically done
Every patient is different, and each practice works differently, so a real visit may vary. This outline shows the usual flow so there are fewer surprises for you or your child.
- 01
Measuring pockets
Gentle measurements around each tooth show where gums have separated and how deep pockets are.
- 02
Numbing for comfort
Local anesthetic is commonly used, and treatment may be divided into sections of the mouth.
- 03
Scaling and root planing
Deposits are removed from beneath the gumline and roots are smoothed to support healing.
- 04
Reevaluation
Pockets are measured again after healing to see how gums have responded and to plan ongoing care.

After a deep cleaning
Gums may be tender and teeth may feel sensitive for a few days. Warm salt water rinses and gentle brushing usually help. As inflammation settles, many people notice less bleeding and fresher breath.
Staying on track
Gum health often needs more frequent maintenance cleanings after a deep cleaning. Consistent home care, especially cleaning between teeth, plays a large role in keeping pockets from returning.
Questions families ask
How is a deep cleaning different from a regular cleaning?
A regular cleaning focuses on tooth surfaces at and just above the gumline. A deep cleaning treats root surfaces below the gumline where pockets have formed.
Will I need more than one visit?
Often, yes. Treatment is commonly split into quadrants or halves of the mouth for comfort, followed by a reevaluation visit.
