Can toothpaste damage or corrode teeth?

Tooth paste: Sure. Depends on the size of the granules. Usually natural toothpastes are more abrasive and should not be used.

No: Any toothpaste which has received the american dental association seal of approval should not damage your teeth. These toothpastes have undergone testing to earn the seal, and there should be no ingredient in them which would harm your teeth.

No: Toothpastes may contain a number of ingredients including a mild abrasive, flavoring, foaming agents, purported whiteners, desensitizers and, typically but not always, fluoride. None of these has the ability to damage your teeth although their salutary effects are often disputed.

Not corrode: The more abrasive the toothpaste the more it is possible to damage your teeth if you brush too hard.

Very abrasive ones: Some toothpastes that are marketed and promoted as "whitening" toothpastes can be very abrasive and can wear away teeth if used on a regular basis. You can google it and get a list of toothpastes with their abrasive index to see which ones are the most harmful. There is no problem with any ada accepted non-whitening toothpaste. Excessive brushing with "hard" TB can also wear tooth structure.
