Due to the presence of a rigid cell wall, bacteria maintain a definite shape, though they vary as shape, size and structure. When viewed under light microscope, most bacteria appear in variations of three major shapes: the rod (bacillus), the sphere (coccus) and the spiral type (vibrio). They measure about 0.25 Âµ and are the smallest cells known so far. 2  They were formerly known as pleuropneumonia-like organisms (PPLO). 3  Mycoplasma gallicepticum, with a size of approximately 200 to 300 nm are thought to be the world smallest bacteria.
Replacing 1 front tooth would cost about $50 so about $100 for 2 front teeth but the cost will vary depending upon your dentist and his experience level. To know the exact cost you must consult your dentist.
Was referred by dentist at age 45. Teeth were falling out of course 1 by 1. When the first front tooth was loose I decided for full dentures. First set cost me an arm and a leg, charged everything, $18,000, at 45 I wanted a smile. Had pay for pulling of the teeth, shaving the jaw bone for smoothness, and of course the dentures itselve, $12,500.
