What is Tooth Enamel?

As enamel plays a major role in protecting your teeth from cavities, you should do everything in your power to prevent it from eroding. Enamel forms a strong barrier that protects the inner layers of your teeth from the effects of acids and plaque; it also protects the sensitive inner layers of your teeth from foods and beverages that are very hot or very cold.

When enamel is destroyed, your body does not produce more to replace it. Unlike other parts of your body – such as bones, for instance – enamel does not contain any living cells, so it cannot regenerate.

You can protect your enamel by avoiding foods that are known to cause a lot of damage. Sugary foods and drinks, together with acidic fruits and beverages, are among the most damaging to your tooth enamel. When those substances stick to your teeth and interact with germs in your mouth, lactic acid is produced and can damage your enamel. Avoid these foods when you can. If you do consume them, remember to rinse your mouth with water first, then brush thoroughly.

Very hard foods, like hard candy or ice cubes, can also damage your enamel by causing it to crack or chip. As such, these foods should also be avoided. If you do indulge in hard candy, suck on it rather than biting down on it.

Of course, you can also protect your enamel by practising good oral hygiene habits and visiting your dental professional for regular professional cleanings.

Enamel is an important substance that deserves to be taken care of and protected as part of good oral hygiene. You can learn more about tooth anatomy in the Colgate Oral Care resources.
