I received a dental implant in August 2014 and since then the crown on the implant has broken twice. My dentist replaced it at no charge, but I am not getting a good explanation as to why this is happening. Can you give me an idea of why this might be happening? Thanks. Yvonne
Yvonne – When an implant crown breaks there are several possible causes:
- Bruxism (teeth grinding) – If you grind your teeth while you sleep, it puts extra force on them. Teeth and crowns can weaken or break from the force.
- The crown itself – When a crown is made from substandard materials, it can break easily. Even a crown made of quality materials, if incorrectly formed, can easily become weak and break.
- Crown placement – Proper positioning and securing of the crown is required to help it withstand the force of biting and chewing. It must be ensured that your bite (the way your teeth fit together) is properly aligned. When any these factors are off, a crown can easily break.
It is good that your dentist willingly replaces your broken crowns, but if the problem persists, you can consider getting a second opinion from a dentist who is experienced with both dental implants and crown placement.
