Dental care for recovered drug addicts

In the past I had a severe problem with drug abuse for years that caused a lot of problems in my life. One of the many consequences of my actions is severe damage to my mouth. For example, it’s so bad that there are holes forming in the roof of my mouth. I’ve been too embarrassed to contact a dentist. I don’t know much about any resources, but is there an office that is more accepting/more common for recovered addicts to go? I feel like if I just walked into a random dentist office they’d be horrified and most likely judgmental and I don’t know if I could face it.
