It was the 19th century when a revolutionary dentist left a mark on the field of dentistry. Born in 1870, Weston Price was initially a conventional dentist; his curiosity led him to delve deeper into the links between dental health and overall well-being.

Price embarked on expeditions in the 1930s, visiting remote, indigenous communities untouched by modern diets. What he discovered challenged conventional wisdom: these communities had exceptional oral health, with virtually no tooth decay or dental deformities. Their secret? Traditional diets rich in whole, unprocessed foods.

Price's groundbreaking research upended the prevailing belief that dental problems were primarily due to poor oral hygiene. Instead, he argued that diet played a pivotal role. The introduction of refined foods like white sugar and white flour into Western diets, he contended, was a major factor in dental issues.

His 1939 book 'Nutrition and Physical Degeneration' documented his findings and emphasised the importance of essential fat-soluble vitamins, particularly vitamins A and D, in maintaining oral health. Price laid the foundation for nutritional dentistry, connecting diet and oral well-being.
