My daughter had to get three implants (three front upper teeth) due to an impacted canine tooth in the palate dissolving the roots of those permanent teeth when she was nine. She lost one when the was thirteen and got a prosthetic tooth on her retainer. Then at 18, when she was finally old enough, she got her two front teeth extracted by an oral surgeon (they were barely hanging on), three rods immediately implanted, and then an hour later, her prosthodontist fit her with a temp bridge while the rods bonded with the bone. She was only “toothless” for an hour. The temp bridge was not removable and looked great.
Then about 7-8 months later, she got the permanent implants. They looked even better. The prosthodontist who worked with her is the team dentist for two pro sports teams in our area including a hockey team. The whole process including the oral surgery (tooth extraction x2 and implants x3) and both the temp bridge and permanent crowns x3 cost us $11.5K. We live in a high cost of living area. So I think the 7K for just one tooth sounds high.
I’ve read that implants don’t last forever and could need to be replaced in 10 years or so.
