“How long do molar implants last?”

When all goes as planned, molar implants CAN last for life. Implants need to be cleaned, daily at home, and professionally as your dentist recommends. Implants can be damaged by excessive biting force. As teeth can shift and implants do not, your dentist should check the bite annually. Smoking can decrease the success rate of implants.

Under ideal conditions (including your overall health and, specifically, your oral health), properly placed molar implants can last upwards of 40*+ years.  They have a successful retention rate of over 90%.  It is important to remember that the implants need to be taken care of as well
as or better than real teeth.  If teeth are lost due to negligence, replacing them with implants requires elevation of home care and diligently following your dentist's directions.
