Prevention or cure? which one is more substantial and why?

in relation to strength specially Dental Community, which is more important, PREVENTION or CURE? why?Prevention or cure? which one is more substantial and why?
In relation to dental issues, my inference would be prevention. If you get your teeth cleaned every 6 months as suggested, you can hopefull avoid things similar to cavaties and gum disease, or at the very tiniest find them early while you can hold the tooth filled to some extent than pulled and so forth. Dentists can also find problems with the roots of teeth and the chin bones with the x rays they clutch.
The 'cure' to many dental issues will include extensive cleaning that require anesthesia or lots of numbing, removal of the teeth, and surgery. All those things are much more espensive than paying to hold your teeth cleaned twice a year.
They both are incredibly important. Prevention keep people from need a cure, but the cure is needed when prevention is unsuccessful.
prevention,we wont have to look for cures adjectives the time if we just work harder at prevention!but sluggishness stops us!
Prevention is always better, because you may not find a cure, so be erudite prevention is always better.
While today's doctors prescribe prevention medicine, I believe that the only adequate method is to cure the illness. You could spend 100 times more for prevention pills than a enduring cure.

Prevention has to be more prominent. Cures don't always work, and they usually vacate some residual, plus they are usually costly and I could go on.
