The Defenders And The Attackers
Tooth enamel is the hardest substance in the human body. It’s like the castle walls, protecting the softer dentin and pulp inside each tooth. Unfortunately, it is porous and vulnerable to erosion by acids.
When the enamel loses minerals to acid exposure (a process called demineralization), it weakens the teeth and leaves them more susceptible to decay. However, we can fortify that enamel by getting enough minerals and nutrients, remineralizing our teeth. This is the battle our mouths are fighting every day: demineralization versus remineralization.
The invaders in this battle are bacteria. They feed on sugar and carbs left in our mouths after a meal, and they excrete enamel-eroding acid onto our teeth. Luckily, we have a natural defense against the bacteria, and that’s our saliva. If enamel is like castle walls, then saliva is like the moat. A lot of harmful bacteria falls into this moat and gets washed away instead of being able to attack the castle walls.

Which Side Will You Fight On?
While our enamel and saliva are built-in defenses, there is a lot we can actively do to make sure the good guys are winning the battle in our mouths. When we practice mouth-healthy habits, we’re fighting on the right side, but when we neglect them, we’re fighting on the side of the bacteria.
One thing you can do to fight back against harmful bacteria is cut back on junk food. Sugar-filled treats and drinks and other processed foods supercharge the bacteria that lead to tooth decay, but foods like apples, cheese, eggs, carrots, celery, fish, and dark leafy greens promote remineralization of your enamel. Choose your snacks with your teeth in mind!
You can also prevent demineralization by brushing your teeth with fluoride toothpaste. Fluoride remineralizes your enamel too, and it also reduces bacteria’s ability to produce acid.
Never Give Up! Never Surrender!
You are the most important part of the battle for your teeth, so make sure to do everything you can so that your teeth can win the fight. Your reward will be a healthy smile for life. Keep up the good work brushing, flossing, and eating a mouth-healthy diet, and don’t forget that you can always schedule a dental appointment to give your teeth’s defenses a boost!
