One thing I learned as a kid is that tooth decay happens over a period of time. If you wake up one morning and find a hole in one of your teeth, sugar demons did not do it. If you eat a lot of spices, you should brush more often.
Spices contribute to bad breath.
All this demands that you have a narrowly defined way of keeping your mouth happy. If you allow laziness and indifference to creep in, then you should expect to have a swamp in your mouth. Truth requires a consistent set of rituals too. It requires constant diligence in examining the things that God created and investigating how he has interacted with his creation since the beginning of human history. This helps you distinguish God's truth from mere opinion.
