Can I leave toothpaste on my teeth overnight?

No, you generally should not leave toothpaste on your teeth overnight; it's better to spit out the excess and avoid rinsing with water to let fluoride work, but leaving a significant film can irritate gums, promote bacteria, and potentially harm enamel over time, so spitting thoroughly is key, especially for those not prone to cavities. For cavity-prone individuals, dentists often suggest not rinsing after brushing to maximize fluoride, but this means spitting well and letting the residue sit for a bit, not coating your teeth all night.
