There are several methods for teeth cleaning.
My gums often bleed when I brush my teeth, and the gaps between my teeth seem to have become larger. I heard there are several different methods for dental cleaning—how do I know which one is right for me? Will my teeth become more sensitive or uncomfortable after cleaning?

In general, teeth cleaning can be divided into five methods: ultrasonic scaling, manual instrument scaling, sandblasting, laser scaling, and pneumatic sonic scaling.
1. Ultrasonic Scaling
Ultrasonic scalers generate high-frequency vibrations that, along with water irrigation, effectively remove dental plaque and tartar from the tooth surfaces and gum pockets.
2. Manual Instrument Scaling
Dentists use specialized instruments to manually remove plaque and tartar from the tooth surfaces and gum pockets. This method is suitable for areas that are difficult to reach with ultrasonic scaling.
3. Sandblasting
Sandblasting uses a high-pressure air stream to propel fine aluminum oxide or calcium carbonate particles onto the tooth surfaces to remove pigmentation and light deposits of tartar.
4. Laser Scaling
This is a more advanced teeth cleaning technique. It utilizes the thermal and photochemical effects of lasers to precisely remove tartar and stains from the tooth surfaces, while also providing some antibacterial effects. Laser cleaning causes less damage to the teeth but is relatively more expensive.
5. Pneumatic Sonic Scaling
Pneumatic sonic scaling combines pneumatic and sonic technologies to clean teeth with gentle vibrations, reducing the discomfort associated with traditional scaling methods and causing less irritation to the gums.
It is recommended to undergo regular dental cleanings in daily life to effectively prevent periodontal disease, freshen breath, and improve appearance.
