Most people are used to the routine of a standard cleaning every six months, but sometimes your gums need more than a surface-level polish. If you've noticed bleeding gums, persistent bad breath, or your dentist mentioning "pockets" during an exam, you may be dealing with the early signs of gum disease — and that's when deep teeth cleaning becomes necessary.
At Silicon Valley Dentistry, Dr. Vivian W. Cheng, DMD, helps Milpitas patients understand exactly when a regular cleaning is enough and when it's time for something more thorough. Below, we walk through the signs, the science, and what actually happens during a deep cleaning appointment.

A standard professional cleaning, also called dental prophylaxis, removes plaque, tartar, and surface stains from your teeth. It's an essential part of preventive care and is generally recommended twice a year for most patients.
Deep teeth cleaning is different. The initial stage of treatment for periodontal disease usually involves a thorough cleaning that may include scaling or root planing. These non-surgical procedures target etiologic agents like dental plaque and tartar that cause gingival inflammation and disease — and they're commonly performed for cases of gingivitis and moderate to severe periodontal disease.
Understanding regular cleaning vs. deep cleaning comes down to this: a routine cleaning maintains healthy gums, while a deep dental cleaning treats gums that have already been affected by disease.
How do you know when a routine cleaning may not be enough? These signs may indicate the need for periodontal care:
These signs you may need a deep cleaning can indicate gum disease. Without treatment, ongoing inflammation can damage the gums and supporting bone, potentially leading to tooth loss.
Dr. Cheng only recommends scaling and root planing after a thorough examination of the mouth, which may include x-rays and a visual assessment. The decision depends on several factors: the condition of the gums, the amount of tartar present, the depth of the pockets, and how far periodontitis has progressed. This is why routine dental examination and cleaning visits matter — they give your dentist the chance to catch these warning signs early, before they progress further.
Scaling and root planing is performed in two distinct steps:
Scaling removes calculus and plaque attached to the tooth surfaces, especially the areas below the gumline along the root. This is done using a specialized ultrasonic scaling tool, which often includes an irrigation process to deliver antimicrobial agents beneath the gums and help reduce oral bacteria.
Root planing removes cementum and surface dentin embedded with unwanted microorganisms, toxins, and tartar. The root surface is smoothed, which promotes healing and makes it more difficult for bacteria to colonize the area again in the future.
In some cases, a local anesthetic may be used during the procedure for comfort. Antibiotics or antimicrobial rinses may also be recommended afterward to help control bacterial growth, and Dr. Cheng may place antibiotic fibers directly in the periodontal pockets after scaling to control infection and encourage normal healing.
Deep cleaning for gum disease can help:
It's worth noting that when pockets between teeth and gums become too deep, it becomes difficult to thoroughly remove plaque and tartar even with treatment. Patients can rarely keep these pockets clean on their own, which means surgery may eventually be needed to restore periodontal health if the condition isn't caught early enough.
While deep cleaning treats existing gum disease, prevention remains the best long-term strategy. Daily brushing and flossing prevents most periodontal conditions from developing in the first place. Other factors that affect gum health include smoking, diabetes, stress, teeth clenching and grinding, certain medications, and poor nutrition.
The best way to prevent gum disease is a combination of effective daily brushing and flossing along with regular professional examinations and cleanings. Unfortunately, even with diligent home care, some patients still develop periodontal disease — which is exactly why routine periodontal cleaning and prompt gum disease treatment remain so important when symptoms appear.
Led by Dr. Vivian W. Cheng, DMD — a graduate with honors from Tufts University School of Dental Medicine — Silicon Valley Dentistry has served the Milpitas community since 1984. Every recommendation for gum disease treatment, including scaling and root planing, follows a thorough exam so patients understand exactly why a deep cleaning is being suggested rather than a standard one.
