There are various tools for calculus picking, but it should be noted that all the suggested tools need to be operated by a medical professional, so do not feel that you can remove tartar completely by blindly using some tools. The general tools for calculus removal are divided into scalers and scrapers, and scalers are divided into ultrasonic scalers and manual scalers, both of which can remove supragingival tartar. Ultrasonic scalers are more commonly used to remove tartar and plaque from the gingival sulcus by means of ultrasonic vibrations. However, it is still important to emphasize that all these tartar removal tools need to be operated by a professional dentist.
