Please recommend a dentist in the northwest area of Cheonan City~ㅎ

A few weeks ago, I went for a dental scaling, and during the regular check-up, they told me that the outer part of my molar had a crack, and I needed to remove the filling inside and get a gold crown. However, the price was quite expensive, and since I wasn't in pain, I thought about waiting a bit longer. But others advised me to try a different dental clinic. So, I don't want to go just anywhere, and I was wondering if you could recommend a good dental clinic. I had treatment in Sinbu-dong before, but it was very expensive, and the filling there cracked afterward. ㅠㅠ
