When I started the SCD Diet I just happened to have my regular teeth cleaning scheduled right around 2 months in. I practice relatively good oral hygiene and floss regularly, so I was shocked when my dental hygienist was interrogating me about the excessive plaque build up on my teeth. She had the impression I was barely brushing! We finally came to a realization together when she asked if I had changed my eating habits at all recently and I explained the SCD Diet to her. As it turns out, the process of chewing crunchy, hard foods actually helps to clean and remove plaque from your teeth.
