Socket Preservation is a procedure that reduces bone loss after tooth extraction. Your jawbone may become narrow after you lose your teeth. It may lose as much as 60 percent of its volume within the first six months. In that case, you may need Socket Preservation before your same-day implant treatment can start. If you do not agree to undergo Socket Preservation treatment, you may not qualify for implant surgery.
