In fact, there's usually no reason for you NOT to keep your teeth your entire life, providing you maintain a healthy balanced diet and practice good oral hygiene.
Another desirable side effect of good oral hygiene: avoiding more serious problems such as hypertension, cardiovascular disease, diabetes, and even stroke. Indeed, medical research is beginning to show that a healthy mouth equates to a healthy body and a longer life.
Dexterity and Arthritis
People who suffer from arthritis or other problems of dexterity may find it difficult and painful to practice good oral hygiene.
Thankfully, industry has responded with ergonomically designed devices such as toothbrushes and floss holders that make it easier to grasp and control. The use of electric or sonic brushes is a great way to help ease the difficulty of grasping a toothbrush.
You can also use items around the house to help you. Inserting the handle of your toothbrush into a small rubber ball, or extending the handle by attaching a small piece of plastic or Popsicle stick may also do the trick.
Floss can also be tied into a tiny loop on either side, making it easier to grasp and control the floss with your fingers.
