Scared to go to dentist 😨😨

Okay so when I had insurance with my mother I would go every 6 months no problem... well that was up until I was 18. Since then I haven't been able to afford dental (I'm 21, turning 22 next week) but now that I'm pregnant I have dental because of my pregnancy.. I worried that I'm going to need some sort of major work done since I haven't been to the dentists in basically 4 years 😨😨 I keep putting off making an appointment even though I know I shouldn't 😓😓 I don't know what to do......
