Washing teeth won't make them white, only bleaching teeth can. Regular tooth cleaning should be about 100 yuan, including tartar removal and polishing. 30 yuan for tooth cleaning will definitely save a lot of steps, and poor disinfection in general stores will bring infection to the mouth. It is recommended not to go. Boyfriend 10.6 went to wash his teeth, mainly to clean tartar. So is the doctor's advice. Bleached teeth are unnatural Don't wash your teeth if there are no special problems. Patients with gingivitis are more depressed. Boyfriend just lost a lot of blood and needed medication. It's terrible.

At present, tooth washing is divided into ultrasonic tooth washing and normal saline tooth washing. The latter is more expensive. It may be more scientific, but I don't have this service here. Boyfriend washes his teeth with ultrasound.

I wonder if it will help you. Finally, I hope you can go to a regular big hospital instead of a small shop to wash your teeth. For the sake of health.
