Are Ceramic Crowns a Metal-Free Option for Me?

I have three porcelain on metal crowns, but I want to get ceramic crowns instead. After successful cancer surgery last month, I want to reduce as many risks as possible and treat myself to new crowns. I read online that crowns contain metal ions. Should I be concerned? Also, I want my teeth whitened before the crowns because they are yellow from 30 years of smoking. I quit smoking when I got a cancer diagnosis, so whitening my teeth will make me feel more confident. Are ceramic crowns the way to go to reduce my metal exposure? Joshua

Joshua,

Although all-ceramic crowns do not contain metal known to provoke reactions, they have metal ions.

Metal Ions

Metal ions are essential for human, animal, and plant life. These ions are in the human body:

  • Calcium
  • Cobalt
  • Copper
  • Magnesium
  • Manganese
  • Molybdenum
  • Potassium
  • Zinc

Lithium

Lithium is in the sodium family. The ceramic lithium disilicate is in strong ceramic dental crowns, including e.max crowns.

Zirconium

Zirconia crowns are of high strength. Dental ceramists use zirconia to build dental bridges that are so strong they do not need a metal framework.

Advanced cosmetic dentists understand the types of ceramics available for dental crowns and will work with you to find a ceramic that matches your needs.

The condition of your teeth and the location of your crowns affects the type of ceramic that will look natural and be durable. Look for an experienced cosmetic dentist who understands which ceramics are best for front and back teeth for aesthetics and durability.

Teeth Bleaching

Ask your cosmetic dentist which brands they use and research the contents. Your dentist will work with you to ensure your metal-free crowns match your whitened teeth.

Best wishes for your healthier smile with new crowns.
