BU students, profs offer free dental care in Mexico

Cierres la boca,” says Alexandra Antonescu, instructing a pediatric patient to close his mouth around a suction tube.

That’s one of the frequently used Spanish phrases that Antonescu (SDM’11) learned from a cheat-sheet taped to a wall in the St. Pierre dental clinic in Teacapan, Mexico, where last month, a team of students and faculty from BU’s Henry M. Goldman School of Dental Medicine provided free dental exams, sealants, and fillings to children from 3 to 17.

“Coming here was a culture shock,” says fourth-year dental student Antonescu, who works mainly with adults back in Boston. “I didn’t know much Spanish, and you need to talk them through procedures. It was hard, but toward the end of the week I got a lot more comfortable.”

dental_mexico3_hVenezuelan native Jennifer Soncini, an SDM clinical assistant professor, steps in for Antonescu when communication is tricky. But, Soncini says, Antonescu doesn’t give herself enough credit.

“Even if she uses a wrong word, the kids still understand,” says Soncini (SDM’02), who has practiced pediatric dentistry for more than 25 years. “Language is not a barrier. If you smile, kids know you’re happy. We could take our dental students to China to treat patients.”

For this mission, SDM partnered with Project Stretch—a Natick-based nonprofit that since 1988 has provided free care for more than 20,000 children worldwide. The group visits Teacapan, on Mexico’s west coast, for three weeks each spring.

“They don’t get dental care until we arrive,” says Kathleen Held, an SDM assistant professor and the school’s assistant director of extramural programs. “When children have abscesses, doctors place them on antibiotics. They learn to live in pain.”


Daily wages for the farmers and fishermen of the town run from $5 to $40 a day, and a single tooth extraction can cost as much as a week’s pay. Even if care were affordable, it’s rarely available: the closest real dental clinic is 25 miles away. Project Stretch volunteer Brenda Irvin says many families can’t even afford the bus fare, let alone the cost of dental care.

It may sound bleak, but the St. Pierre clinic has come a long way. Back in 2006, when Held and Soncini traveled to Teacapan, the clinic didn’t have dental chairs or compressors. They worked outside in the heat, providing sealants, extractions, and fillings with a “scoop and fill” method (known as atraumatic restorative treatment), because they didn’t have a compressor to operate handpieces.

“We pushed back plastic chairs, wore headlamps, and operated with patients’ heads on our laps,” says Soncini. “It’s a way to understand how you can do so much with so little.”


Today, St. Pierre is a fully functional clinic, with real dental chairs and a compressor.

Project Stretch partners with Amigos de Teacapan, a group of Mexicans and Canadian and U.S. expatriates who host dental teams in their homes and run the clinic. They transport kids from schools, manage medical files, and while patients wait for treatment, teach them how to brush and floss. And to set them up a lifetime of better dental health, they teach the children about which foods make wiser choices. (Do not, for example, take a bottle of Coca-Cola to bed at night.) In addition to the educational outreach at the clinic, teachers are trained to give fluoride treatments, four times a year.

In week one, the first team of seven professionals—BU dental students, faculty, and staff, as well as a Boston-area assistant and hygienist—performed 350 dental exams and fluoride treatments, 900 sealants, 241 fillings, and 31 extractions over four and a half days.

Project Stretch dentists transport all supplies from Boston, stuffing gauze, gloves, tongue depressors, amalgam, syringes, anesthesia, and hand tools into extra baggage they check on their flight. Supplies are donated by corporations and local dental practices, including SDM’s clinic.


Like most international externships, competition for the Project Stretch program is fierce.

Of 110 fourth-year dental students, 2 were sent to Teacapan, an additional 12 to other locations abroad. The students’ airfare is covered by SDM’s alumni association.

“We need more young dentists excited about these missions,” says Frank Schiano (CAS’01, SDM’06,’07), an SDM clinical assistant professor and director of dentistry at Fenway Health.

“It inspires them to get involved in community health abroad and back here in Boston.”

    great video

    This is a great piece — and great to see how students are helping out where it’s really needed.

    BU should be proud it sends dental students and faculty to places like Teacapan for health care and education. It’s incredible to see the kind of service they’re providing for a poor population, and I bet it’s a wonderful learning experience for the providers too–both educationally and personally. Coming back from a place that like helps to put life into perspective.

    Happy kids at the dentist

    Happy children, going willingly to the dentist, is a sight to see. My childhood memories of visits to the dentist (granted, it is 50 years ago) were of fear and dread. These children looked as if they were going to a party. Go BU for making dentistry fun!

    Service and Education

    In addition to the dental service BU provided in Teacapan, I like that they visited the schools to provide education. It seems like this is an incredible community health program.

    HEY! I watched the video and it is amazing!!! I was once Dr. Schiano”s assistant at AGED Department in Boston University and we have the same kind of situation in my Country also. (Cape Verde) where children who aren’t able to afford the expenses of a simple dentist visit and I was just thinking maybe we can expand this and go there and I will gladly volunteer to help out where its needed. Take Care Maria B. :)

    The video you produced is a good documentary to inform other people about their predicament. It is regretful that some of these kids fail to maintain good oral health because of poverty. Your international externship has been a blessing to these kids. They are surely thankful for what you have done and all you have given to the community. I’m sure they would appreciate it if you came back every now and then.

    I really appreciate the professors and dental students of the Boston University for their initiative oral health checkup and education in village of Teacapan, Mexico. Tooth decay is also known as dental cavity, it starts when bacteria that produces acid surrounds the tooth, these bacteria can also be called plaque. Fluoride in your teeth always plays an important role to kill tooth decay before it starts to eat your teeth. And by the way thanks to Robin Berghaus for nice clicks. Keep doing this kind of good job.
