I've had no problems, neither has DH
- the important thing is to keep the socket area really clean, my Dentist advised those Tee-pe small brushes to get between each gap and clean thoroughly. This avoids any chance of infection.
Your Dentist should have given you a printed off treatment plan prior to your agreeing to the procedure which would have told you that ABs would be required, this should have been discussed anyway to check for allergies i.e. Penicillin - as well as exactly what the procedure will entail and excepted treatment time. The implant is a foreign body drilled into the jaw bone hence the requirement for it to heal before the 'tooth' is put on. Saves time and expense should the bone reject the implant.
The bit I hated was biting down on the Plastecine to take the mould of the tooth shape. Also the implant was unscrewed and the socket checked before the tooth was put on. I got quite blasé
The reason I had mine done is because the jaw requires teeth in order to maintain health: similar to brisk walking helps osteoporosis: otherwise the gum retreats which loosens other teeth. I didn't want a plate nor bridges because my teeth in general are so un-even. Hence the 3 implants. DH has 2 for the same reasons.
