Deep Cleaning: Procedure, Benefits, And What To Expect

Sometimes your mouth requires a deep cleaning procedure. Gum disease can develop gradually and may not be immediately noticeable. As plaque and bacteria build up below the gumline, the gums can become inflamed or swollen, and the teeth may begin to look or feel less healthy—especially if brushing habits or daily oral care routines change.

In these situations, your dentist or dental hygienist may recommend deep cleaning teeth, also known as scaling and root planing, to treat existing gum disease and help stop it from progressing further.

Scientific evidence has consistently shown that electric toothbrushes can support better plaque removal and gum health compared to manual toothbrushes, making them a helpful part of ongoing oral care—especially after professional treatment.

In this article, you’ll learn more about deep cleaning teeth, what the procedure involves, and what to expect from your dental professional so you can feel informed and prepared.

• Deep cleaning teeth, also known as scaling and root planing, is a dental procedure used to treat gum disease by cleaning below the gumline. During the procedure, specific areas of the mouth are typically numbed so dental professionals can remove plaque and tartar from deep gum pockets and along the tooth roots.

This type of cleaning is more involved than a routine professional cleaning and is performed when gum disease has progressed beyond what regular cleanings can manage. Its goal is to reduce infection and inflammation, helping stop the disease from worsening and supporting overall oral health.

Like a routine cleaning, deep cleaning removes plaque and tartar buildup—but it reaches areas that brushing, flossing, and standard cleanings cannot. Specialized scaling and root planing instruments are used to thoroughly clean these deeper areas and smooth the tooth roots.

A deep cleaning procedure typically takes about one to two hours per visit. In many cases, your dentist or dental hygienist may recommend treating the mouth in sections—often one side or quadrant at a time—to allow for thorough cleaning and patient comfort. As a result, completing a full deep cleaning may require multiple appointments.

Your dental professional will explain why a deep cleaning may be recommended, identify areas of concern in your mouth, and walk you through what to expect during the procedure. While a deep cleaning may look similar to a routine professional cleaning, a local anesthetic is typically used so dental professionals can clean more thoroughly below the gumline, including deep gum pockets and along the tooth roots, with minimal discomfort.

During a deep cleaning, dental professionals use specialized hand instruments and other professional tools designed for scaling and root planing. Plaque and tartar are carefully removed from areas that routine brushing, flossing, and standard cleanings cannot reach. The teeth may also be flossed and polished, similar to a regular cleaning, once the deeper areas have been treated.

Deep cleaning is used to treat existing gum disease by removing disease‑causing bacteria from below the gumline and helping stop the condition from progressing. Based on your individual needs, your dental professional will recommend appropriate follow‑up care to support healing and long‑term gum health.

• After deep cleaning, it is crucial for patients to maintain excellent oral health and to brush and floss daily to prevent renewed plaque and tartar buildup.

• Your dentist or dental hygienist will monitor your progress and will likely recommend regular dental cleanings every few months as part of your deep cleaning aftercare.

• Brushing with an electric toothbrush supports gum health and provides a more thorough clean compared to a regular toothbrush.

Obtain an estimate from your dentist or dental hygienist for the deep cleaning cost. Your dental insurance can confirm the extent of coverage and your out-of-pocket expenses.

• The deep cleaning cost can be up to $1,600 and varies significantly based on your dental professional's fees and your dental insurance plan. If X-rays are required, the deep cleaning teeth cost may increase.

The cost of a deep cleaning can vary based on the number of areas treated, the severity of gum disease, and your dental insurance coverage. Deep cleanings are often billed per quadrant (one‑fourth of the mouth), and not every patient requires treatment in all areas.

Your dental office can provide a personalized estimate, and your dental insurance provider can help clarify coverage and out‑of‑pocket costs. Additional services, such as X‑rays or anesthesia, may affect the total cost.

A routine professional dental cleaning differs from a deep cleaning procedure, which involves cleaning below the gum line and specifically addresses gum disease and gum recession. Similar to a routine professional cleaning, a deep cleaning also removes plaque and tartar from the teeth and polishes your pearly whites. Aside from the more extensive deep cleaning procedure, the primary distinction is that patients receive a local anesthetic to numb areas of their mouth, allowing dental professionals to clean deeply into the gums and tooth roots painlessly.

Healthy gums are paramount for overall tooth and mouth health. In the event of gum disease (such as gingivitis), the initial course of action is to consult a dental professional. They can conduct a proper examination, determine the severity of periodontal disease, and recommend appropriate deep cleaning treatment. However, there are also steps you can take to help.

• Toothpaste such as Crest Pro-Health Gum Detoxify contains stannous fluoride, which combats the plaque bacteria that cause gum disease. Pair that with an Oral-B iO electric toothbrush to help stop bleeding and reverse signs of early gum disease.

• Mouthwash can be an important component of your daily oral health routine. The best mouth rinses, like Crest Mouthwash, are clinically proven to provide 24-hour protection against plaque and gingivitis with twice-daily use.

• When you brush with Oral-B iO electric toothbrushes, you can protect your gums and help prevent further gum recession. Oral-B iO helps you avoid new tooth and gum issues—and if you have existing gum problems, it can resolve them more quickly than a manual toothbrush.

• The right toothbrush head, such as the Oral-B iO Ultimate Clean brush head, is crucial for effective cleaning without gum irritation. Pair your toothbrush with this head, which removes plaque and features different bristle lengths that reach deep into the spaces between your teeth where plaque bacteria love to hide.

• Dental floss, used daily, helps prevent gingivitis as part of a complete dental plan. Look for a floss that can fit more easily into tight spaces, such as Glide Floss.

There is a connection between oral health and systemic health, so it’s crucial to treat conditions like tooth decay and gum disease as promptly as possible. Crest & Oral-B have developed a range of products to address various oral health conditions.
