Early Cavities Can Sometimes Heal Without a Filling
SANTA MONICA – November 02, 2026 -- Early tooth decay does not always call for a filling, according to a HelloNation article featuring Dr. Kari Sakurai of Pacific View Smile Center, who explains that mineral loss in enamel can sometimes be reversed before a hole forms.
Enamel can regain minerals if its structure is intact
In the earliest stage, decay involves mineral loss from enamel without a physical cavity. Dentists often call this enamel demineralization. Bacteria in the mouth produce acids that strip calcium, phosphate and other minerals from enamel, and frequent exposure to sugars and fermentable carbohydrates can intensify those acid attacks.
A white or chalky area can be an early sign. At that point, the surface has not yet collapsed into a cavity.
