Birch bark xylitol and hydroxyapatite mints

Studies have determined that xylitol boosts dental health and helps prevent tooth decay.
One of the leading risk factors for tooth decay is an oral bacteria called Streptococcus mutans. This is the bacteria most responsible for plaque.
Although some plaque on your teeth is normal, excess plaque encourages your immune system to attack the bacteria in it. This can lead to inflammatory gum diseases like gingivitis. 
these bacteria cannot use xylitol for fuel, they still ingest it. After absorbing xylitol, they are unable to take up glucose — meaning that their energy-producing pathway is clogged and they end up dying.
In other words, when you use these mints with xylitol the harmful bacteria in your mouth starve to death.
xylitol-sweetened mints can reduced levels of bad bacteria by 27–75%, while friendly bacteria levels remains constant.
Hydroxyapatite 
helps replenish lost minerals in enamel, strengthening teeth and making them more resistant to decay. 
Magnesium Hydroxide
It's alkaline, so it can neutralize acids in the mouth that contribute to tooth decay and enamel erosion by reducing acidity, it helps create an environment less favorable for Streptococcus mutans, the main bacteria that cause cavities.
Ceylon Cinnamon 
fights harmful oral bacteria It helps reduce bacteria like Streptococcus mutans, which contribute to tooth decay and plaque. Its anti-inflammatory action can help soothe irritated gums and reduce swelling.
