Spitting can be a very bad habit one can have. But spitting toothpaste will improve your dental health. After brushing spit out but don't rinse out - this allows the fluoride in the toothpaste to stay on your teeth for longer.
Toothpaste contains a lot of useful ingredients, including fluoride, to protect our teeth. To get the maximum benefit from those ingredients, they need to stay on the teeth for as long as possible. However, many people rinse out with a big mouthful of water straight after brushing and all those protective ingredients go straight down the drain!
Fluoride is the single most important ingredient in the toothpaste. It helps us to maintain dental health by strengthening the tooth enamel, making it more resistant to tooth decay. It also reduces the amount of acid that the bacteria on our teeth produce.
If you rinse your mouth with water after brushing, you wash out most of the fluoride from the toothpaste and loose the main benefit of fluoride strengthening your teeth.
So just spit out the excess after brushing, don't rinse, and just walk away :-)
What about mouthwash?
My advice is to use mouth rinse at a different time from brushing. For example brush when you get up, use mouthwash when you leave the house. Or use mouthwash after lunch if you cannot brush. This will give you the advantage of an increased frequency your teeth are exposed to fluoride, helping you to combat sensitivity and reduce risk of dental decay and cavities.
