An innovative gel that forms a layer over teeth and then recruits calcium and phosphate ions from saliva to build new enamel has the potential to change dental treatment. To date, we don't have any way to regenerate the tough outer layer of enamel on our teeth as it erodes with age.
I have had four teeth replaced with the oral surgeon doing the screw and the dentist did the crowns. Yes it is expensive, but reasonably common, and partially covered by dental insurance.
luckily i had root canals and dont need extractions than implants, if you try to get implants on the “cheap” like less than a few thousands you wont get results, i had a family member get1 tooth for 6k, while my parents getting theres for 2-3k, not very good results, plus advertising as using new “tech”
