Competent cheap dentists

Hello, so I recently moved to Houston and Ive been having a few problems with my teeth. Bunch of cavities and a broken tooth. Long story short Im on the Aetna dental health plan and im a graduate student. I had an appointment for an x-ray today and found out about a lot of work that needs to be done. Mainly cavities and crown installations.

For the priority work, i will end up using up all my health plan benefits and will need to pay 2k out of pocket. If i want to do all the necessary work then im looking at around 7k. Im an international student and cant afford this at the moment, and im not too familiar with how health care works here in the US. This plan was given to me by one doctor, so i do still need to shop around i guess. But i was hoping to get some advice on what i can do. Any good dentists would be very appreciated, specially when it comes to getting crowns installed. Ones on the Aetna health plan that wont require me to sell my car would be great.

Edit: Oh im staying next to museum district, so anything close to that would be highly appreciated

Thank you 🙏
