What Is the Dental Code D8670?
During dental treatments, codes depict, standardize, and are used for services by the dentist; thus, the services become obvious, communicable, and billable. One of the dental codes, D8670, refers to the periodontal maintenance operations that follow the next step after periodontal therapy (e.g., scaling and root planing) has been carried out. In essence, this code is the one that is extremely significant for the gum’s health and the prevention of a broader range of problems that could be the result of periodontal disease, for instance, the loss of teeth.
Periodontal treatment is the removal of periodontal disease. Code mainly refers to regular cleanings, scaling, and root planing that are done on the parts under the gums to remove the plaque, tartar, and bacteria that cause the continuous development of periodontal disease. Periodontal maintenance program after treatment for periodontal disease patients with infected gums is a program in which their gums stay healthy, and the disease does not happen again.
What Periodontal Disease Is and Why It Is Harmful?
Periodontal disease or gum disease is a bacterial infection that initially affects only the gums; however, this may lead to the loss of teeth if the infection is not properly treated. The most common origin of the infection is gingivitis, which is the mildest form of gum disease, and at this stage, the gums are swollen and bleeding. Anyway, if gingivitis is left untreated, it may progress to periodontitis, which not only injures the gums but also the bone that supports the teeth.
The consequences of ignoring periodontal disease are very severe and include:
- Tooth Loss: As the infection spreads to the bones and the tissues that hold the teeth, these become very weak, and therefore, teeth may fall out or even be detached.
- Systemic Health Risks: Scientists have found that gum disease is the main cause of a whole bunch of other problems in the human body, such as heart disease, diabetes, lung infections, and pregnancy complications.
- Difficulty in Chewing and Speech: As a result, the development of the disease may cause the loss of dental pieces, thus reducing the person’s ability to chew and speak properly.
Therefore, it is really important to keep the periodontium in good working condition and take care of it through regular visits such as those at Dental Code D8670.
What Is D8670?

The dental code D8670 is the one that refers to the periodontics maintenance of patients who have undergone an initial periodontal therapy, such as scaling and root planing (D4341, D4342). Therefore, after the first treatments, which consist of the cleaning of the area under the gums to eliminate bacteria and tartar, D8670 is the procedure for follow-up care.
With the help of this intervention, not only is the return of the periodontal disease avoided, but the preservation of the teeth and gums in their healthier state is also facilitated.
Normally, a D8670 operation can cover the following:
- Scaling Root Planing (Deep Cleaning): The very first thing is to remove the buildup of plaque and tartar from the roots of the teeth, i.e., the area under the gum line.
- Polishing and Cleaning: Polishing is carried out after the scaling and root planing in order to ensure that the fragments of tartar and plaque that are embedded in the tooth surface are completely removed.
- Gum Health Assessment: A dentist or hygienist will check the gums visually and also feel them for swelling, recession, or infection. If needed, pictures of the bone around the teeth may be taken to determine its condition.
- Ongoing Care Recommendations: Apart from the mechanical part of the operation, the dentist or hygienist will also give you advice on personal dental care, which includes the proper brushing methods and the use of certain dental products to help keep a healthy mouth.
As for the patients, the frequency of such visits is at most every 3 to 4 months, which is, however, dependent on the oral health condition as well as the dentist’s suggestion. Regular checkups make it possible to keep the gums in a healthy condition, and also, if needed, early intervention can be done in case any problems arise.
Who Needs Dental Code D8670?
Dental Code D8670 is mainly targeted at patients who have already been subjected to radical periodontal treatment for gum disease. Normally, this kind of treatment is only fit for those individuals who have been diagnosed with periodontitis or have shown the advanced symptoms of the gum disease.

- They are infected with gum disease or have had a history of periodontal infections.
- Have you experienced scaling and root planing or surgical treatments as a way of managing your gum disease?
- They are very likely to get gum disease because of factors like smoking, diabetes, poor oral hygiene, or a family history of periodontal disease.
Regardless of the fact that you may feel the healthiness of your teeth, continuous care is very important after the first treatment in order to avoid the return of the disease. Dentists usually advise D8670 to be done regularly to keep up the work achieved in the initial stages of periodontal therapy.

- D1110 and D1120: These are the codes that stand for prophylaxis (regular cleanings) in the case of patients without signs of gum disease, and they are different from D8670, which concentrates only on the health maintenance of patients with a history of periodontal disease.
