This is a really common question which mostly comes from a cultural misunderstanding of how teeth decay.
No, Shine will not fill in an existing cavity like putting a filling into the hole will. But Shine can help to support the remaining tooth structure. Shine will also help replace minerals lost in ‘soft spots’ as tooth decay is progressing before it becomes a full blown cavity. In this way, Shine supports the body’s natural remineralization ability.
Our teeth are made of minerals and proteins that are bound together in a honeycomb-like crystal structure. When an area has become demineralized but the “scaffolding” remains intact, minerals can be delivered to that demineralized area to strengthen the tooth.
However, if the actual tooth structure has become compromised (teeth that are chipped or broken, that have dental work, etc.), we can no longer simply remineralize that area to restore the tooth. Instead, we shift our focus to delivering minerals to what remains of the natural tooth structure, to ensure that it receives sufficient minerals to stay strong and cavity-free.
