Ronald Henderson, D.D.S owns an innovative dental practice called Healthy Smiles in Dover NH. He has more than 34 years of experience in dentistry. His philanthropic contributions recently include the donation of an antique wishing well to the Joe B. Parks Public Garden project in downtown Dover. In 2007, Dr. Henderson led a campaign that generated more than 1,300 donations of toothbrushes and other dental supplies from the community for his medical mission to Peru. He was also honored by the Mayor of Dover, Scott Meyers, for his commitment to the community and his dedication to the well being of others throughout the world.

Dr. Henderson received his D.D.S. degree from the Purdue University of Dentistry in Indiana, and went on to receive post graduate training in cosmetic and advanced restoration procedures. Healthy Smiles incorporates the two disciplines of cosmetic and restorative care. Dr. Henderson is a member of the ADA, the Academy of General Dentistry, the Academy of Cosmetic Dentistry, and the Seacoast Esthetic Dentistry Association and various other advanced study organizations. In his spare time, Henderson has served on the Wentworth-Douglass Hospital Board as both a member and as chairman of the board for more than nine years.
Poor dental hygiene practices can lead to plaque, tarter, gingivitis and gum disease - all of which results in tooth and bone loss. However, what most people don’t know, especially baby boomers, is that the dental care they received when they were children may be causing tooth and bone loss faster than any form of bacteria. Silver fillings were typically used in dental practices in the ‘60s, ‘70s and ‘80s, when many baby boomers had their cavities repaired. These cheaper restoration materials are starting to damage people’s teeth by causing hairline-type fractures throughout the filled tooth. This is due to the failing of the once satisfactory material; in conjunction with the length of time patients have had these fillings. In fact, studies have shown that within three to seven years, these fillings will need to be drilled out and redone.

According to Dr. Henderson, sixty-five percent of men and women approximately 40 to 65 years of age have silver fillings that are breaking down. Microscopic cracks are occurring in their teeth as a result, and if left untreated these cracks can lead to fractured teeth, root canals and potential tooth and bone loss. Dr. Henderson is among only 6% of dentists that use the CEREC 3D, which allows the restoration of damaged teeth with natural-colored ceramic. These ceramic restorations are stronger and less likely to cause future damage, and they can be created in about one hour. Dr. Henderson has performed over 1,000 CEREC restorations on patients.
The business that he opened as Healthy Smiles in 1989 has transformed into a high-tech center of dentistry, and Dr. Henderson has been a practicing dentist in Dover since 1972. His business specializes in the use of state-of-the-art CEREC technology, which allows him to restore teeth, replace crowns and place veneers in a single visit. Everything from x-rays, checkups, periodontal, cleaning, and repair are done here. The friendly staff is ready to sit down with you and take care in providing the greatest dental services you’ll come to expect in a healthy smile!
