The main advantages of dental implants are:
- With dental implants there is no need to trim (damage) neighboring teeth to replace lost teeth. Bridges have long been a good option for tooth replacement, but they do require trimming the adjacent natural teeth, which over time can lead to failure of these teeth due to overloading or decay.
- Dental implants make it easier to maintain good oral hygiene, as they can be brushed and flossed just like natural teeth. Bridges on the other hand require a special technique with a special floss.
- Dental implants have a longer life span than bridges or removable dentures. In 10-year studies, it was found that the success rate for implants was 90%; while for bridges and dentures it was 50%. The studies also showed that when a bridge failed the supporting teeth often had to be extracted or required root canal treatment. The few times that implants failed they simply had to be replaced, with no harm to the neighboring teeth.
- Dental implants stimulate bone growth in the area surrounding the implant, unlike dentures or bridges which do not prevent the bone loss that occurs over time when teeth are missing.
