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.
If the other teeth are loose then the Dentist is correct in telling you to remove them as well or if you are making a partial denture it will need to be re made when each of the other teeth come out. If the Dr is charging $480 a tooth then it is for a 6 unit fixed bridge. That is very reasonable. need to have 4 of my front bottom teeth extracted. I have not seen a dentist in 16 years and finally did. He referred me to his partner who gives IV sedation.
