A Nigerian influencer recently ignited a lively debate online by recommending that people avoid rinsing their mouths immediately after brushing their teeth. She highlighted that dental experts advise simply spitting out the toothpaste instead of washing it away with water.
Her explanation centers on fluoride, a vital component in toothpaste that fortifies and shields teeth from decay. Rinsing right after brushing washes away this protective layer before it can fully benefit the enamel.
She also emphasized that maintaining a routine of brushing twice daily without immediate rinsing can effectively reduce bad breath and combat halitosis.
Dental authorities have supported this viewpoint for years, noting that fluoride creates a protective barrier on the teeth, which helps prevent cavities and strengthens enamel. Removing it too soon diminishes these advantages.
Experts recommend that after brushing, individuals should spit out the excess toothpaste but avoid rinsing with water for about 30 minutes. This allows the fluoride to remain on the teeth longer, enhancing its cavity-fighting properties.
Though this advice may seem unconventional to those accustomed to rinsing right away, oral health specialists stress that such minor changes can significantly boost dental hygiene over time.
The influencer’s message quickly gained traction on X (formerly Twitter), sparking a range of reactions. While some dismissed it as unnecessary, others praised the advice, recognizing its alignment with professional dental recommendations.

@Sybaddest: “Who even allows these people on social media? Next thing you know, they’ll tell us not to use sponges anymore.”
@Felix NDUDI: “She’s actually correct. Fluoride in toothpaste protects and strengthens teeth. Brush, spit, and avoid rinsing with water for at least 30 minutes.”
@Zelsa.sats: “You don’t have to skip rinsing completely. Try brushing, then take your shower, and rinse afterward. It really helps with fresh breath. This lady always shares useful tips.”
