Which statement about bulimia and dental health is true?

• A. It can lead to dental erosion and tooth decay
• B. It does not affect dental health
• C. It has no effect on teeth
• D. It only affects the stomach

Answer: (A)

Repeated vomiting in bulimia exposes teeth to stomach acid, which chemically erodes the enamel—the hard outer layer of teeth. This enamel erosion weakens the tooth surface, can cause sensitivity and changes in appearance, and as enamel wears away, teeth become more vulnerable to decay. So bulimia can lead to both enamel erosion and an increased risk of cavities. The other statements don’t fit because bulimia does affect dental health, and the impact is not limited to the stomach.
