To minimize enamel erosion risk in Crohn's disease or colitis patients, which toothpaste ingredient should be avoided?

• A. Sodium lauryl sulfate
• B. Fluoride
• C. Xylitol
• D. Coconut oil

Answer: (A)

Sodium lauryl sulfate is a foaming detergent that can irritate the oral mucosa. In Crohn's disease or colitis, the mouth is more sensitive and prone to ulcers, so using a toothpaste without this irritant helps keep the mucosa comfortable and supports gentler brushing. When brushing is gentler and the mucosa is less inflamed, there’s less risk that brushing becomes aggressive or that protective saliva dynamics are disrupted, which can contribute to enamel erosion. Fluoride, xylitol, and coconut oil don’t carry this mucosal irritant risk, and fluoride actually protects enamel. Therefore, avoiding sodium lauryl sulfate is the best choice for minimizing erosion risk in these patients.
