Hello, I am missing the first and second molars on both the left and right sides of the lower jaw. My dentist suggested a bridge on both sides, but it seems a shame to grind down the second premolars because they are healthy. The wisdom teeth on both sides have fillings. I think it would be better to replace the missing teeth with implants. I would like to know whether one implant on each side would be sufficient, or whether four implants would need to be placed, one for each missing tooth. Thank you for your answer.
