Cavities are one of the most common dental health issues worldwide, affecting people of all ages and backgrounds. That said, depending on the region, the context, and whether you are speaking formally or colloquially, several other terms are frequently used. The most direct and universally understood translation for cavities in Spanish is caries. Because of that, if you are learning Spanish, traveling to a Spanish-speaking country, or working in a bilingual healthcare environment, knowing the correct terminology is essential for clear communication. Understanding these nuances ensures you can accurately describe symptoms, understand a dentist’s diagnosis, or handle a pharmacy aisle with confidence.
The Primary Medical Term: Caries
In clinical, academic, and formal settings across the entire Spanish-speaking world, the standard word is caries. It is a feminine noun (la caries), though it ends in 's', which often confuses learners into thinking it is plural. Grammatically, it is treated as a singular collective noun referring to the disease process itself.
- Singular: La caries (The cavity / Tooth decay as a condition).
- Plural: Las caries (Multiple cavities / Multiple instances of decay).
You will see this term on medical charts, insurance forms, and toothpaste packaging. Now, for example, a dentist might say: "El paciente presenta caries en el primer molar superior" (The patient presents cavities in the upper first molar). Something to keep in mind that caries refers specifically to the disease process or the lesion caused by bacterial acid erosion, not just the physical "hole" in the tooth Simple as that..
Common Colloquial Terms: Picadura and Agujero
While caries is the medical gold standard, everyday conversation often relies on more descriptive, visual words. The two most prevalent colloquial terms are picadura and agujero.
Picadura (literally "bite" or "sting," from picar – to bite/sting/peck) is widely used in Spain, Mexico, and parts of Central America. It conceptualizes the cavity as a spot where bacteria have "bitten" into the enamel Simple as that..
- Example: "Me duele la muela; creo que tengo una picadura." (My molar hurts; I think I have a cavity.)
Agujero (literally "hole") is perhaps the most intuitive term for learners because it describes the physical manifestation of advanced decay. It is understood everywhere but is considered less technical.
- Example: "El dentista encontró un agujero grande en la muela del juicio." (The dentist found a big hole in the wisdom tooth.)
Both terms are perfectly acceptable in a dental office during a casual consultation, though the dentist will likely chart the finding as caries Which is the point..
Regional Variations Across the Hispanic World
Spanish is spoken officially in over 20 countries, and dental vocabulary shifts slightly depending on geography. Recognizing these regional preferences helps avoid confusion.
Mexico and Central America
In Mexico, picadura is extremely common, often used interchangeably with caries. You may also hear hoyo (hole), similar to agujero. A uniquely Mexican colloquialism for a severe cavity or abscessed tooth is muela picada (literally "pecked/bitten molar"), which implies the tooth is significantly damaged.
Spain
In Spain, caries is used frequently even in casual speech, perhaps more so than in Latin America. Still, picadura remains the standard colloquial synonym. You might also encounter destrucción dental (dental destruction) in more technical explanations regarding the extent of the damage.
The Caribbean (Cuba, Dominican Republic, Puerto Rico)
Here, caries dominates. Picadura is understood but used less frequently than on the mainland. Agujero is the go-to word for the physical hole. In Puerto Rico, due to the influence of English, code-switching is common, and you might hear Spanglish phrases like "Tengo un cavity" mixed into Spanish sentences.
South America (Colombia, Venezuela, Ecuador, Peru, Bolivia, Chile, Argentina)
- Colombia/Venezuela: Caries and picadura are standard. Hoyo is used for the physical hole.
- Southern Cone (Argentina, Chile, Uruguay): Caries is the primary word. Picadura is understood but sounds slightly foreign or old-fashioned to some; agujero or hoyo describes the hole. In Argentina, the lunfardo (slang) term curado is occasionally used in very informal contexts to describe a tooth that has been treated/filled, but rarely for the active cavity itself.
Describing the Stages: From Mancha to Absceso
To communicate effectively about dental health, you need vocabulary beyond just the noun for "cavity." Describing the stage of the decay helps a professional understand the urgency Took long enough..
- Mancha blanca (White spot lesion): The earliest stage, reversible with fluoride. Incipient caries is caries incipiente.
- Caries de esmalte (Enamel caries): Decay has broken through the enamel but hasn't reached the dentin.
- Caries de dentina (Dentin caries): Decay has reached the softer layer under the enamel. Sensitivity to cold/sweets usually starts here.
- Caries profunda (Deep caries): Decay is near the pulp (nerve). High risk of pulpitis.
- Pulpitis (Pulpitis): Inflammation of the nerve. Reversible vs Irreversible.
- Necrosis pulpar (Pulp necrosis): The nerve has died.
- Absceso dental / Flema (Dental abscess / Gum boil): Infection has spread to the bone and soft tissue. Flema is a very common colloquial term for the visible swelling/boil on the gum.
