In recent years, sea moss has become very popular on social media, especially TikTok and Instagram. It is often promoted as a “superfood” that may help the skin, digestion, immune system, and even dental health.

But can sea moss really help teeth and gums? In this article, we will explore the potential benefits, risks, and best ways to use sea moss for oral health.

What is sea moss?

Sea moss (Chondrus crispus) is a red algae that grows on the rocky coasts of the Atlantic Ocean, Europe, and the Caribbean. Its high content of essential minerals has made it a superfood that’s good for oral and general health.

What nutrients are in sea moss?

Sea moss contains many nutrients important for general and dental health:

• Calcium: strengthens teeth and bones
• Magnesium: helps form enamel
• Phosphorus: works with calcium to protect teeth and jawbone
• Zinc: helps control harmful bacteria in the mouth
• Iodine: supports thyroid health (too much can be harmful)
• Potassium and Sodium: help balance fluids and support muscles
• Vitamin B2 (riboflavin):  supports energy production and cell repair
• Antioxidants: reduce gum inflammation
• Fluoride: strengthens enamel and helps prevent cavities

Sea moss also contains carbohydrates, small amounts of protein and fat, and is about 80% water.
