Dentists are not recommended, very inefficient!

Dentists are not recommended, very inefficient!
At the time of registration, I was not told that I couldn't fill my teeth that day. I ended up waiting for 2 hours. The result was "I don't know when I can make up my teeth because it is full." I only use X-rays and teeth...

If the staff at the counter can clearly inform the process, let the patient know the situation before wasting time waiting, this should also save the time and the doctors' work of some patients who have no way to get proper treatment!
