Dr. Monacell at Midlothian Family Dentistry helped me through my dental anxiety. I hadn't been to a dentist in 30 years. No judgement from anyone on the staff. I kind of eased my way from oral sedation dentistry to nitrous and now I don't need anything at all for ordinary cleanings and such.

Tell your friend to opt for sedation dentistry if they need work done. Once the meds kick in, they will be so chill and will not give a damn that they are at the dentist.

I also joined a dental anxiety forum that really helped me to feel like I wasn't alone. People there are so supportive and will have similar backgrounds. https://www.dentalfearcentral.org/forum/

Good luck to your friend!
