Is this how dental treatment is usually done...?

No matter how diligently I brush my teeth, molars and wisdom teeth are hard to take care of, so cavities tend to form easilyㅠㅠ

However, since that area is also difficult to see well, it seems that it is not easy to detect without visiting the dentist.

So I make sure to visit the dentist once a year for a regular check-up, but I started to have a question about the treatment method.

I was brushing my teeth and inspecting them closely when I found a decayed area. Since my dental check-up is coming up soon, I thought I could just take care of it then, so I left it as is.

I had made an appointment to go for a dental check-up, so I didn't ask about any discomfort separately, and I thought the doctor would notice when examining me, but the treatment ended as usual...?

So I mentioned it, and they said to see me at the next appointment, and they scheduled it again.

I'm not sure if other dental clinics also provide treatment in this way since I haven't visited many dental clinics.

I want to hear about other people's experiences!!
