17. Drinking kombucha
Kombucha has many health benefits, including improved digestive health and reduced heart disease risk. However, this fermented beverage is not a top drink among dentists. Just like lemons, kombucha is pretty acidic, too. So, rinse your mouth with plain water after drinking kombucha.
18. Vaping
If you thought that vaping is not as harmful as cigarette smoking, think again… Because nicotine is a vasoconstrictor, it can lead to gum issues and even bone loss in the mouth, as well as around the teeth. So do your teeth and overall health a favor and quit both smoking and vaping.
