Dr. Robert M. Young believes in comfort almost as much as he believes in healthy smiles. At Brassfield Cosmetic & Family Dental Center, he surrounds guests with homey touches: hardwood accents, overstuffed couches in the waiting room, antique furniture and pastoral paintings, and video-game systems set up and waiting to play. Such comforts even follow guests into the treatment rooms, where personal TVs hang over the chairs so that patients can watch their favorite shows while the doctor and his staff fix crooked, cracked, and stained teeth. Yet even though the decor is domestic, the equipment is anything but. Dr. Young can peer into the hidden spaces above and below the gum line with digital x-rays, cover teeth with custom veneers, and obliterate stains caused from mistaking a highlighter for a toothbrush with an in-office whitening system.
