How come bad teeth only get worse?

The body is designed to heal itself if you allow it to do so/help it out a bit (i.e.: a broken bone will try to mend %26amp; calcify even if it's not "set" correctly; or, an infected cut in the skin will heal up if you treat the infection and don't irritate the cut; etc.)





How come teeth don't work like this? I have never heard of anyone who suffered from an infected tooth (a cavity, basically) that got better without dental treatment.

I think God wants us remeber this phrase..... "Eat to liv, dont live to eat."

Reply:because your teeth arent really like a part of your body, there are no bones nerves or anything.
Reply:The acids from our foods irritate the protective layers of the tooth. You can have a tooth recalcify if the cavity is not too big.


If we didn't have doctors to take care of our sicknesses we would be dying at the age of 30-35 and the teeth last long enough for that without dentists. But since we live to 80, we have to make the teeth last that long or get dentures.
Reply:Bone can mend because it is completely internal to the body. Inside the body, the bone can be supplied with blood through a pervasive circulatory system, and is a living tissue.





A tooth on the other hand is not internal to the body-- Part of it is exposed to the outside world, and the part that is exposed is not living tissue (the enamel, which has no living cells in it). There is no way for a circulatory system to reach the enamel to repair it because it is outside the body.





Hope this clears things.
