How Effective are the Enamel Building Toothpastes?

Did you know that tooth enamel is the hardest tissue in the body, but once it’s lost, it cannot regenerate on its own. Toothpastes marketed for “rebuilding” or “repairing” enamel don’t actually grow enamel back — instead, they help strengthen and protect the enamel you still have. Here’s how they work and how effective they really are:

How Do These Toothpastes Work?

Support Remineralization - Toothpastes with fluoride or ingredients like hydroxyapatite and calcium phosphates strengthen weakened enamel by redepositing minerals such as calcium and phosphate into the enamel. By strengthening the enamel, the tooth is more resistant to attacks from acidic food and drinks.

Acid Protection - They also offer protection from acids by coating the tooth. This is especially true if the toothpaste includes stannous fluoride.

Sensitivity Relief - Sensitivity is caused by the thinning of enamel leaving the dentin of the teeth exposed. Sealing the dentin and tubules protects the tooth and can eliminate the sensitivity when eating or drinking.

The 3 key ingredients to look for when purchasing a toothpaste to address the loss of enamel:

First, fluoride enriched toothpastes, either sodium or stannous fluoride which are both proven to harden enamel and prevent tooth decay. Secondly, nano-hydroxyapatite (nHAp) a biomimetic material similar to natural enamel and helps with sensitivity. Finally, calcium phosphate like CPP-ACP, also called Recaldent) which assists in delivering calcium and phosphate ions back into the enamel.

Enamel repair toothpastes are effective for strengthening enamel and best for early-stage enamel weakening. They are most effective when used daily, with good oral hygiene as well as a low-sugar diet. They DO NOT REGROW LOST ENAMEL! They are best as supportive and preventative dental tools, not a cure.
