Most toothpastes contain fluoride, which has been proven to prevent cavities. Fluoride also can stop small cavities from getting worse. It can even reverse early tooth decay.
Tartar-control toothpastes are useful for people who tend to build up tartar quickly. Someone who gets tooth stains may want a whitening toothpaste. Whitening toothpastes will remove only surface stains, such as those caused by smoking, tea or coffee. To whiten teeth that are stained at a deeper level, talk with your dentist.
Your needs will likely change as you age, so don't be surprised if your hygienist recommends a type of toothpaste you haven't used before. Look for the ADA seal of approval on any toothpaste. The seal assures that the toothpaste has met the standards set by the American Dental Association. Then, choose the toothpaste that tastes and feels best. Gel or paste, wintergreen or spearmint: These work the same way, so pick the one you like.
Some people find that some toothpaste ingredients irritate their teeth, cheeks or lips. If your teeth have become more sensitive or your mouth is irritated after brushing, try changing toothpastes. If the problem continues, see your dentist.
