Does ultrasonic teeth cleaning harm the teeth?

Generally, if not performed properly, ultrasonic teeth cleaning may cause certain risks such as gum bleeding, tooth sensitivity, root exposure, oral infection, and enamel damage. The specific analysis is as follows:

1. Gum Bleeding

During ultrasonic teeth cleaning, if the instrument's movement is too aggressive or dental calculus is severe, the removal of tartar may create local wounds, leading to gum bleeding.

2. Tooth Sensitivity

After ultrasonic cleaning, teeth may become temporarily sensitive due to the exposure of previously covered surfaces following tartar removal, resulting in a sensation of soreness or tenderness.

3. Root Exposure

During the ultrasonic cleaning process, excessive force from the ultrasonic vibrations may damage the gums, potentially causing root exposure.

4. Oral Infection

If non-professional ultrasonic equipment is used or dental instruments are not thoroughly sterilized, there is a risk of cross-contamination through blood, which may lead to oral infections.

5. Enamel Damage

Although ultrasonic teeth cleaning typically does not cause significant enamel damage, improper technique or overly frequent procedures may result in physical wear or micro-cracks on the enamel surface.

When opting for ultrasonic teeth cleaning, it is important to choose a reputable medical facility and inform the dentist about your individual oral health condition. After cleaning, maintain good oral hygiene and avoid consuming excessively hard or hot foods—such as nuts, bones, or hot pot—to protect your teeth and gums.
