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.
The cost of a single-tooth dental implant can range from $1,000 to $3,000. The cost of the abutment and crown can range from $500 to $3,000. In total, the cost of a full dental implant can fall between $1,500 and $6,000. This is the out-of-pocket price for the full procedure of a single tooth implant including the consultation, the implant, abutment, and crown. If you need to replace multiple teeth, the costs only go up.
