Dental implants have a slightly higher success rate when placed in your bottom jaw compared to your top because your bottom jaw naturally has a higher bone density. However, the biggest factor when looking at jawbone density as a determining factor for implant success usually has more to do with how long you’ve gone without replacing your missing tooth or teeth. When you have a missing tooth, the jawbone in which the tooth’s root lived is no longer receiving stimulation. Just like failing to use muscle results in smaller muscles, failing to stimulate your jaw bone results in it beginning to diminish. When this occurs, your bone becomes fragile and is more prone to fracture and there simply is not enough bone to house your dental implant.
Your implant could also fail later in life due to osteoporosis. Osteoporosis is a medical condition where the normal process of your body absorbing and replacing bone is interrupted and your body can’t replace the bone as fast as it is being absorbed. In those who have dental implants, osteoporosis could cause your implant to fail.
Another determinant is age. Children are not candidates for dental implants partially because their jawbone is not fully developed. Besides that, children’s teeth move around as they lose their baby teeth, get their adult teeth, and when orthodontics are in play. Implants are permanent and do not move like natural teeth. Check to see if you are a candidate for dental implants.
