Dan-A Miso Dental Clinic Scaling: A Disappointing Treatment Experience

I came here because I was thinking of getting my teeth scaled before the end of the year.
I've been there a long time ago, so it's been a while since I've been there.
It was late in the afternoon so there weren't many patients so we had to treat them quickly.
I received it. It didn't hurt and the intensity was just right when scaling.
But at first, I thought I would come here again because it felt like I was exploring every nook and cranny.
I felt like they were doing the lower teeth roughly.
Scaling is painful so I'm thinking about doing it once a year, but I'm going to do it anyway.
I wanted to receive it cleanly ㅜ
When you're done, please tell me you're done. I didn't know it was over because I was told to swallow a lot of blood. I don't know who the person who performed the procedure is.
The precautions were given by someone other than the practitioner.
Please tell me... It's been a while since I've been to a doctor, but he was so rude
I have a feeling I won't be visiting anymore.
