If cavities are caused by bacteria and alcohol is very efficient at killing them why alcohol is not used in toothpaste production?

The goal of brushing your teeth isn’t to kill bacteria outright – it’s to remove deposits of food and plaque that allows bacteria to thrive and multiply, and excrete lots of acid that damages your teeth.
Actually sterilizing your mouth would be hard to do and require very high concentrations of alcohol. And it’s pointless because new bacteria would colonize your mouth in no time. Not to mention, there are plenty of good bacteria in your mouth that are important for good oral health and hygiene, for instance because they out-compete other (bad) microbes and thus help prevent fungal infections and the like.
