If disease can be preventable why is it here?

Dental plaque for example, you can avoid dental problems by simply brushing the plaque off, or killing it with mouth wash.

If we can prevent something like this, then why are we plagued by it in the first place? And I'm talking about the plaque in particular.

STD's are a little different because often sinning may be involved from you know what with multiple partners.

But why dental plaque?

One or more of factors such as these:

• Ignorance of the problem
• Indifference to the problem
• Poverty, coupled with directing limited funds to other needs
• Laziness
• Mental illness
• Ineffective cleaning technique
• Distraction from other illnesses
• Distraction from other problems
• Etc.

Summary: humans are not perfect. (But we already knew that.)

Not sure I understand your question. Obviously plaque can be almost entirely prevented. Equally obviously, to do so would require a daily extra time commitment and personal discipline. Therefore, given that, correctly or otherwise, people do not see dental plaque as a major threat to their well-being, it is not surprising to me that people still get dental plaque.

Removing plaque takes some work. Like brushing at least twice a day, and flossing and/or using a proxabrush to remove debris trapped between the teeth. Which I do regularly. And even then, you need a professional cleaning at least twice a year. Because plaque hardens into tartar, which can only be removed professionally. And I'm fortunate to have dental insurance which covers more than half the cost.

Excessive tartar buildup causes periodontal disease, i.e., gingivitis. Which, if persistent and severe, can lead to tooth loss. And there's evidence that chronic low grade inflammation of the gums, which is what gingivitis is, can be a risk factor for heart disease, and maybe even dementia.

Please remember that dental plaque is caused by bacteria. They do something called quorum sensing . If they’re few in number they act like normal bacteria . If they have a lot so that they form layers, they form a biofilm with the same bacteria taking on different jobs. For example , almost like a multicellular eucaryotic organism ( like animals ) that has skin for protection or a stomach for digestion made of cells with the same DNA doing different jobs, .bacterial Biofilms are hard to get rid of and dental plaque is only one type because if you leave one cells behind it will just reform eventually

Because our efforts are not 100% effective. They may not completely eliminate the chance of getting a disease, or people may simply forget to do it.
