Mouthwash For Cavities – Best Tooth Decay Prevention

Protecting your teeth is mandatory! Although, there are so many ways, one of the best is using mouthwash.

Mouthwashes for cavities are a bit special, due to the fact they contain the specific ingredients, including fluoride. This compound affects the weakened enamel and makes it stronger. An interesting fact is that newly formed enamel is stronger than the original. Without fluoride these rinses simply wouldn’t be so effective at all. And do not worry, the amount of fluoride in these solutions is carefully measured and completely safe for your oral and general health.

Another main difference is the ability to kill all the bacteria which cause cavities. These mouthwashes kill Streptococcus mutans (bacteria associated with cavities) and many others, but leave those which are beneficial to oral health. The best mouthwash for cavities must provide all of these and something even more.
