As we age, everyday use, wear and tear has an effect on your teeth. But there's still a lot you can do to keep them for life and in great shape.
All that chewing, grinding, and biting wears away the hard outer layer of your teeth (enamel). It also wears down the parts you use when you bite and chew.
You can't erase a lifetime of wear and tear, without having it fixed by a dentist, but you can keep it from getting worse. Don't chew ice or other hard foods that can cause chips or even break your teeth.
Teeth can also be worn down by a poor bite, which may require orthodontic work, and night time grinding (bruxism), which may require wearing a night guard.
If you have a plate or denture it is important that you leave it out at night to give your gums time to “breathe” and soak it in a cleaning solution (sterident or the like), it is also important that during your daily brushing that you also clean your denture with a soft brush and soap, not toothpaste as it is to abrasive to the denture.
If you are concerned about any of these issues, or have any questions, talk to your dentist.
