Many people assume oral health is completely individual, but the bacteria responsible for tooth decay and gum disease can actually be shared through saliva. This means a partner’s oral health can influence yours through activities like kissing or sharing utensils.
Sugar-free drinks aren’t necessarily tooth-friendly. While they don’t contain sugar, many are still highly acidic—such as sparkling water, diet soda, citrus drinks, fruit tea, and wine. Frequent exposure to acid can gradually wear away enamel.
Your gums cover a surprisingly large surface area in your mouth. If flattened out, the gum tissue would roughly equal the size of the palm of your hand. When gums are inflamed, that represents a significant area of chronic inflammation. Imagine a bleeding pimple the size of your palm on your face, what would you do about it?
After acidic drinks like juice or wine, it’s best to wait about 30 minutes before brushing. Acid temporarily softens enamel, and brushing immediately can cause additional wear. Saliva needs time to neutralise the acid first.
Not all cavities need fillings right away. In the earliest stage, tooth decay can sometimes be stabilised or reversed with fluoride, diet changes, and good oral hygiene. Once the decay progresses deeper into the tooth, however, a filling becomes necessary.
