What essential examinations are required before teeth cleaning?

Teeth cleaning—commonly known as “dental scaling”—is medically termed “supragingival scaling.” It involves the use of specialized instruments to remove dental calculus (tartar), plaque, and surface stains from above the gumline, followed by polishing of the tooth surfaces to delay subsequent plaque and calculus accumulation. So, what essential examinations are required before teeth cleaning? Below, we address this question.

Essential Pre-Cleaning Examinations

Prior to teeth cleaning, a complete blood count (CBC) is required to assess coagulation function and screen for infectious diseases.

Bleeding is common during scaling. If coagulation function is impaired, excessive bleeding may occur—making scaling inadvisable. Additionally, CBC testing helps identify potential infectious diseases, as certain infections can be transmitted via direct contact; in such cases, scaling is generally contraindicated.

Although scaling causes minimal trauma to teeth, patients must be in good general health beforehand. Contraindications include hematologic disorders, active oral inflammation, major systemic organ disease, or infectious conditions. Women should avoid scaling during menstruation, pregnancy, and lactation. Patients with dentin hypersensitivity should undergo desensitization therapy 5–10 days prior to scaling to prevent discomfort (e.g., sensitivity or soreness) during the procedure. Individuals with hypertension or heart disease must fully disclose their medical history to the dentist before scaling to minimize risks of complications.

Most importantly, scaling must always be performed by qualified dental professionals. Using various instruments and devices, these professionals mechanically remove calculus accumulated on tooth surfaces comfortably and thoroughly—achieving effective cleaning and calculus elimination.

The above outlines the essential pre-scaling examinations. We hope this information is helpful to you.
