Think you’ve got nothing to look forward to as you get older? Think again! According to getting older might actually improve your health in a number of unexpected ways.

As the years fly by, it’s easy to focus on the less-than-desirable aspects of your aging physique. But did you know that, in some ways, your body actually gets better with age? In fact, doctors and researchers are discovering that the natural aging process has certifiable health benefits. The changes aren’t dramatic and they certainly won’t turn back the hands of time, but even small physiological improvements can make a big difference when it comes to feeling younger and enjoying life more.

Here’s one of real benefits you can look forward to as you grow older.

Decreased Tooth Sensitivity

If you’ve always had painfully sensitive teeth, they’ll become less so as you age. That’s because the surface between the enamel and nerves lays down more dentin (the tooth’s inner hard tissue) as teeth age, resulting in extra insulation and a diminished pain response. This may make dental procedures less painful, too. “Many older people feel less pain than younger patients — to the point where they may not need anesthesia for simple dental procedures,” said Claire Collins, D.M.D., associate professor of dentistry at the University of Colorado-Denver School of Dental Medicine.

Healthy Advice — boost the comfort and health of your teeth, be meticulous about regular brushing and flossing. “Plaque from food particles can dissolve the teeth’s enamel, which will expose dentin and nerves, increasing sensitivity and pain,” Collins said. So stay on top of your daily dental regimen to help prevent decay.
