George Washington's ivory denture
Queen Victoria's dental instruments
Toothbrushes through the ages
Saint Apollonia

The National Museum of Dentistry is renowned for its collection of dental treasures from the legendary to the whimsical, from George Washington’s not-so-wooden teeth to cartoon character toothbrushes featuring Fred Flintstone and Mickey Mouse. The 40,000-object collection of dental instruments, furniture, and artwork is one of the largest and most significant in the world. A substantial portion of the core collection traces its roots to the Baltimore College of Dental Surgery, the world’s first college of dentistry founded in 1840, and the Museum continues to add to the collection.
Significant objects in the collection include:
- George Washington’s ivory lower denture
- Queen Victoria’s personal oral hygiene instruments
- The first earned dental diploma, dated 1841
- Toothbrushes ranging from the 1800s to the present
- Dentifrice containers, including one dating to the court of French King Louis XVI
- Dental furniture, including dental chairs dating to the early 1800s and the oldest known American dental cabinet (c. 1820)
- An 15th-century stained-glass image of St. Apollonia, patron saint of dentistry
- Extraction instruments dating from the 17th century, including the largest holding of dental extraction keys in the United States
- The world’s largest collection of dental advertising poster art
