Dental Implants To Replace Teeth Are: For life - most patients can expect lifelong replacement. Comfortable - they remove the necessity for dentures that often slip and cause pain. Good for appearances - tooth loss can quickly lead to jawbone shrinkage. Implants stop it. Great for speech - slurring, mumbling and clicking due to dentures all become a thing of the past. Convenient - implants are brushed just like normal teeth, and never slip or fall. Efficient for eating - efficient eating makes for better nutrition.
