Choosing a dentist

I need to perform a simple treatment.

One place has to wait a long time to receive the reservation date.

One place doesn't accept reservations at all and you have to go early in the morning and wait.

I'm thinking of just making a reservation for 1 to 2 weeks later and going at the scheduled time.

The place I wait from the morning doesn't know when my turn will come.

I feel like I'm wasting too much time.
