Size Friendly Dentists in NJ

Can anyone recommend a dentist in NJ with size friendly equipment? I lost a filling over the weekend and my mouth is killing me. 

I remember asking my dentist, and was told the chair held up to 400 pounds....  Otherwise, the rest of the equipment is standard.....     would that be a friendly enough size?  Please post more info, like what county, what size, etc...   and what insurance....   I think UMDNJ in Newark still has a clinic for the not insured....    Good Luck!   Mary
