Sonrisas offers dental treatments that alleviate pain and suffering so that people can strive towards their goals with self-confidence. The treatments include prophylaxis, fluoride, sealants, fillings, crowns, bridges, dentures, root canals, orthodontics, implants and surgical procedures.   Each clinic is equipped with modern equipment and tools -rarely found in other clinics in the DR.  The frequent electrical blackouts in the country's electricity system do not paralyze the clinic's work because each has ts own electrical generator. Most importantly, outside inspectors have said that the clinics are models of cleanliness and hygiene and the dentists are extremely capable.

Essentially, the clinics are well equipped, maintained, and staffed so as to offer the highest quality dental treatments.
By the end of 2010, the total number of educational units and treatments delivered since the initiation of Sonrisas has reached 2,898,222. In 2010 a total of 282 244 patients were treated and educated. This is a significant increase over past years and can be credited to having 2 new clinics up and working, as well as corporate sponsorship and overseas support for the dental offices and mobile clinics. Furthermore, an increase of local interest by community groups and the business sector is a result of growing awareness of the benefits of Sonrisas services, in the community itself and among employees in private companies. The Foundation continues to expect the number of treatments to increase as awareness of their services and their physical presence expand. Smiles Foundation runs 10 permanent clinics named SONRISAS ("Smiles"  in Spanish). Four of them are located in Santo Domingo, one each in Moca, Santiago, Higuey and Puerto Plata. Its 5 mobile units provide dental and educational services to rural areas across the country.
