If you are going to get dental care in the DR, get insurance.
You don't need to be a resident to get local coverage.
Usually they have a 3 month waiting period, so plan ahead.
The cost savings can be substantial.
I have had a lots of dental work here and will finally have the cosmetic stuff finished over the next 2 months. I have saved RD$170,000+ (US$4,500) by having insurance and had my work done at one of the best clinics in the DR. This is on top of the cost savings by having it done in the DR.
On top of the dental I have also had surgery performed at Hospiten (excellent hospital) and saved a fortune.
It's crazy not to have insurance here if you live in the DR.
It's cheap and the coverage is excellent in my opinion.
