Recently, one of my patients came in for her routine 6 months hygiene appointment. During her exam, I diagnosed several cavities. We were not sure why she now had tooth decay, after many years without having any cavities. She is very health-conscious, has good oral home care, and did not think any habits have changed. I started asking her different questions about her diet. She realized the one thing that she has been doing differently in the last year was drinking kombucha on a daily basis. Lately, kombucha has been gaining a lot of popularity for all it’s health benefits. Many people are adding probiotics to their diet to provide their gut with “good bacteria” to aid in digestion and overall health. As a dentist, I even started making kombucha myself. So I decided to do a little research, to see what are the effects of kombucha on your teeth.
It’s no secret that sugary drinks, like sodas and juices, are bad for your health and teeth. Many of us try to replace our cravings for sweet beverages with healthier options like unsweetened tea and now fermented tea. Kombucha is a fermented, carbonated black or green tea that has many health claims such as: improving immunity, increasing energy levels, and improving digestion. You can buy Kombucha or make it at home.
Kombucha is a very acidic drink. It is nearly as acidic as soda. Consuming anything acidic contributes to enamel erosion and lowers the pH of saliva and plaque creating an environment in which teeth demineralize, the first stage of tooth decay.
