Q. Hello,i have always had very weak teeth and they tend to crumble, my hygiene is very good! My two back molars have both split down the middle , i developed a huge abcess here and have been put on 2 antibiotics, the dentist has referred me to the hospital to have both teeth extracted as soon as the infection is cleard, my question is would the NHS (i have a tax credit exemption) pay for me to have two implantsput in there?, when i smile you will be able to see a gap on the side? Also how long do i have to wait after the extraction for the new implants? Thank you
