Most people are suitable for dental implants. However, the chances of your body rejecting the implant are increased in some cases. For example, if you have a medical condition such as diabetes, that isn’t under control, this could lessen your chances of success. Some lifestyle habits can affect how successful your implant might be, such as smoking, using e-cigarettes or taking recreational drugs. If you smoke, your dentist will advise you to give up as it can slow healing and affect gum health. Some people may need supporting treatment before having implants, such as a bone graft or a sinus lift. This is needed when there isn’t enough bone in your jaw to support the implant.
