Hi there.
Have you tried distracting yourself while you brush? I have a kind of mouth phobia and a strong gag reflex so I really don't like brushing my teeth - I feel sick and gag etc - so I have something to read while I brush, so I'm not concentrating on what's going on in my mouth so much. If laziness is a big problem, this could make brushing more 'entertaining' too....well, depending on what you read!
The others are right, though. There just isn't a shortcut. Whilst some things could definitely help you (different brush, different toothpaste, distraction etc), in the end it's your choice either to brush your teeth, or not to. The only way you can have a healthy mouth is to choose to brush.
I will say, you may be surprised how quickly you develop new habits. I went through a few years of brushing my teeth very infrequently, and hated the idea of starting to brush regularly again. But having decided to do it, I kind of made myself brush them every night for a week...and before I knew it, it had become part of my routine. Now, even though I still don't like doing them, and wish I didn't have to, I can't imagine going to bed without it.
The most important time to brush is before bed, so why not try tonight? Forget toothpaste, just brush, for 1 minute. (If you're not sure how, try looking on youtube for an instruction video.) Every change has to start somewhere.
Also, there's some further information here:
