About Astrid the Dental Hygienist
Astrid Diepenbroek R.D.H. Limited Access Provider, came to Waterfall CHC to promote and provide dental hygiene services after 20 years in private practice in 2008. "My first dental hygiene job was at the Open Door Health Center, in Arcata, California, in 1987. That was my first experience in providing integrated health care to a cultural, social and economically varied community."

In 1989, I moved to Coos Bay and was married to a self employed artist/potter. He died of cancer 5 years later, due to a lack affordable health insurance, preventive medical services, delays in diagnosis. After ward, I began to travel to Mexico, Domincan Republic, and Guatemala and serve many children and adults in obtaining dental hygiene and sealant services, realizing the need for dental health services worldwide. Watching the insurance industry change for the worst over the past twenty years, I felt a need to serve the vast majority of people who have no dental insurance "benefit", so as to maintain good conscience of whom I am truly serving - people, not profit driven organizations.

Obtaining the Limited Access Permit in 2002, is a great asset for many dental patients in Oregon, giving access and portability in facilitating dental hygiene for select groups that often have difficulty receiving care in dental offices. This permit allows dental hygienist to practice in a Community Health Center setting, with or without a dentists presence.

I have been a volunteer dental assistant and hygienist with Medical teams International Dental Van since 2003, working in Coos, Lake and Curry counties. Currently, I volunteer at the North Bend Health Dept. screening young children for early dental problems, placing cavity varnish and educating parents about good dental health practices. I have a part-time business, providing homebound and elder dental care, and have educated CNA's and public health nurses and WIC program providers about proper dental care and anticipatory guidance.

Facts About Sealants
  • The most important reason for getting sealants is to avoid tooth decay
  • Sealants are thin, plastic coatings painted on the chewing surfaces of the back teeth
  • Getting sealants is simple and painless
  • Children should get sealants on their permanent molars as soon as their teeth come in
  • 6 year molars come in between the ages of 5 and 7
  • 12 year molars come in between the ages of 11 and 14
  • Teenagers and young adults who are prone to decay may also need sealants
  • Your dentist might recommend sealants for your baby’s teeth
  • Sealants last about 10 years
  • If a small cavity is covered by a sealant the decay will not spread
  • Sealants and fluoride together can prevent almost all tooth decay

Waterfall CHC currently has funding to provide free and low cost sealants to eligible children. Please schedule an appointment at (541) 756 - 6232.
