Dental reception certificate?

Hello, I’m thinking about going into the dental field and want to gain some entry level experience. I’ve been thinking about doing a dental reception course at VCC, however I’d like to see if anyone has any insights. Here are my questions

1. What are the best schools for the certificate? I’ve been looking at ones with practicums.
2. How is the field? Is it saturated? Is it easy to break into? Or is it the type of field where you have to know someone already. How would it be for a recent graduate?
3. Is a certificate necessary? I see a lot of listings requiring the certificate or at least having relevant experience. I think perhaps a practicum would help.

Thanks! Let me know if it’s something worth doing. I really just want a job in a stable field. I need something that isn’t impossible to break into. I also don’t want to pour my time/money into more education if it will not be worth it. I was thinking about MOA but I’ve been reading online that it’s a very saturated field right now.
