If you have a tooth that needs replacing, implants are an excellent option. However, it is important that you are in good health. Diabetes, cancer, or radiation to the jaw may affect the ability of the dental implant to properly graft to your jawbone. You should discuss these conditions (or any other medical issues that you may have) with the oral surgeon.
Alcoholism and periodontal gum disease are also potential problems that will need to be discussed with your dentist prior to making a decision about whether implants are right for you.
