Anyone know of a good dentist in the North London area?

I have decided I want to change my dentist because I feel my current one no longer does a good job!! I feel he doesn't listen to me, and I feel he does not spend as much time checking my teeth as he used to. Thus can anyone recommend from personal experience a good dentist in the North London area (Tottenham, Wood Green, Crouch End, Winchmore Hill, Enfield, Hornsey or Camden areas preferably). I will also consider areas in Central London too.
