There are two primary ways an implant can fail once it has successfully integrated with the bone: 1) poor oral hygiene and/or 2) excessive biting forces. Poor oral hygiene can lead to a destructive bacterial infection called peri-implantitis. Brushing and flossing your teeth daily, combined with routine professional cleanings, can prevent this. Excessive biting forces can originate from either a habit of clenching or grinding your teeth or an insufficient number of implants support your bite. If you have a habit of grinding or clenching your teeth, a nightguard is strongly recommended to protect your implants.
