I'm a patient there now, and I feel that the service there is generally good (except for a few, that is, something like that ...). I can do invisible correction, and the price should be cheaper than that of the Fourth Medical University. If it's generally corrected, it's estimated to be about 1, yuan now. Even if the total cost I calculated for you before is only 7, to 8, yuan, the subsequent series of tooth cleaning (self-selection) will depend on whether you have cavities.
