A dental deep cleaning, formally known as Scaling and Root Planing (SRP), is a therapeutic, non-surgical treatment for established gum disease, or periodontitis. This procedure is distinct from a routine cleaning because it targets hardened deposits and infection that exist beneath the gumline. The goal of this intensive treatment is to remove bacterial toxins and calcified plaque, known as calculus, from the root surfaces. By eliminating the source of the infection, the procedure aims to halt the progression of the disease and allow the gum tissue to heal and potentially reattach to the tooth root.
Differentiating Deep Cleaning from Standard Maintenance
A standard dental cleaning, or prophylaxis, focuses on removing plaque and calculus from the tooth surfaces above the gumline. A deep cleaning is a required therapeutic intervention based on specific diagnostic criteria indicating disease progression. The most common criterion is the measurement of periodontal pockets, the space between the tooth and the gum tissue, using a specialized probe.
Healthy gum pockets typically measure between one and three millimeters. A deep cleaning is indicated when pocket depths consistently reach four millimeters or more, especially when accompanied by bleeding or inflammation. These deeper pockets signify that bacteria and calculus have colonized the root surface below the reach of routine cleaning instruments. Dental X-rays further confirm the need for this procedure by revealing evidence of bone loss around the tooth roots, the defining characteristic of periodontitis.
The Scaling and Root Planing Procedure
The deep cleaning procedure is typically performed over one or more appointments, often treating one quadrant, or quarter, of the mouth at a time. A local anesthetic is administered to numb the specific area being treated, allowing the dental professional to access the infected root surfaces comfortably.
Scaling
Scaling involves meticulously removing all plaque and hard calculus deposits from both the crown and the root surface of the tooth. Specialized instruments, including high-frequency ultrasonic devices and fine manual curettes, are used for this mechanical removal, which extends to the bottom of the periodontal pocket.
Root Planing
Root planing involves smoothing the exposed root surfaces. Bacteria often embed toxins into the tooth’s outer layer, called cementum, creating a rough texture that encourages further accumulation. Planing removes this contaminated layer, creating a clean, smooth surface that makes it difficult for bacteria to reattach. Following the mechanical cleaning, an antiseptic rinse or a localized antibiotic may be placed directly into deep pockets to suppress remaining bacteria and promote healing.
What to Expect During Recovery and Follow-Up Care
Patients should expect temporary side effects after the deep cleaning, including gum tenderness and increased sensitivity to hot or cold temperatures. This discomfort is managed with over-the-counter pain relievers and subsides within a few days to a week. Slight bleeding or swelling of the gum tissue is also common immediately following the appointment.
For the first 24 to 48 hours, a soft food diet is recommended to avoid irritating the treated areas. Patients should also be cautious about eating while the local anesthetic is active. Gentle oral hygiene is encouraged, including careful brushing with a soft-bristled toothbrush to maintain cleanliness without disturbing the healing gums.
Following scaling and root planing, patients transition from standard six-month cleanings to a more frequent regimen called periodontal maintenance, often scheduled every three to four months. This change is necessary because periodontitis is a chronic condition that requires continuous management to prevent the re-establishment of infection. The deep cleaning serves as the initial therapeutic step, but the ongoing periodontal maintenance appointments are the long-term strategy for controlling the disease and preserving oral health.
