Keto, Vegan, and Fasting Diets Can Negatively Impact Oral Health

Keto, Vegan, and Fasting Diets Can Negatively Impact Oral Health

Imagine your mouth is like a little garden.

Different diets are like different kinds of weather.

Some diets, like keto, can make your mouth drier because they change how much watery stuff (saliva) your mouth makes.

Saliva is like rain for your garden, it washes away bad stuff and keeps your teeth strong.

If your mouth is too dry, tiny bugs (cavities) can grow more easily, and your gums can get sore.

Vegan diets might miss out on important plant food for your teeth and gums, and fasting for too long can also make your mouth dry.

But don't worry!

You can still eat these foods.

Just remember to drink lots of water, chew crunchy foods to make more saliva, and maybe take special vitamins.

Brushing your teeth well, especially before fasting, and seeing your dentist helps keep your smile healthy.
