Consider chewing Xylitol gum after eating. Xylitol directly fucks up the bacteria that cause tooth decay. Make sure to get a brand that is mostly Xylitol (I like Pur).
However, be careful if you have a dog, because xylitol is super poisonous to dogs!
Totally agree! I recently switched to a non-xylitol sugar free gum because we got a puppy. But if Xylitol is an option, it adds that extra boost!
