Why do the back teeth seem to decay so much more easily than front teeth?

1. Molars are designed for grinding and tend to get more food stuck between them than front teeth which are used to tear things off. Food also has a longer contact time with molars.
2. As molars are in the back of the mouth people often brush them less thoroughly and it's more difficult to visually see how good of a job you've done.
3. Molars are often packed closer together and get flossed less adequately than front teeth. Wisdom teeth can make this worse as they grow in making the space between teeth even harder to clean.
Making sure you clean, brush and floss the back of your mouth as much as the front can lower the odd ratio as there is no difference in tooth strength from front to back in most cases unless wisdom teeth have cracked and damaged the back teeth.

M$First, most of the food is being chewed with the back teeth, which are made for grinding the food. The molars have deeper crevices which allow more food to get packed in and harder to remove while brushing.
Also, I noticed how there is less space in between the molars, which makes flossing much more difficult. The more difficult the flossing, the more likely that bacteria buildup sets in between the teeth, thus causing decay.
Even those with very good teeth, tend to get cavaties in their molars. My dentist said I have great teeth, a textbook set of teeth. Yet, I have most of my molars filled and even had a root canal.

M$Another reason may be the purpose that your teeth serve. The front teeth aren't involved in as much action as your back teeth.

M$First, we use our back teeth to chew up food. They do a lot of work and are used the most.
Secondly, if we are in a rush to brush our teeth the teeth that seemed to get brushed best are the easier to get to teeth in the front. I have watched my kids spend more time on the front teeth and had to confront them that the harder to reach teeth in the back need just as much brushing and if anything, they need more brushing.
Just my personal thoughts and personal experience. Typically you do not usually here of cavities in the front. I know we can and do get cavities on the front teeth, but usually they are the back teeth. http://www.flickr.com/photos/angelav/33778291/
