Crowns are very versatile restorations and are used for a variety of purposes, including:
Strengthening Damaged or Weakened Teeth: Crowns provide stability to cracked or chipped teeth in danger of breaking and restore teeth that are already broken.
Providing Stability After Dental Procedures: Large fillings and root canal therapy are very effective treatments used to treat and repair tooth decay or inflammation and infection, but they can weaken teeth and make them more likely to break if they're not protected with crowns.
Correcting Cosmetic Issues: Crowns conceal discolorations and chips, lengthen short teeth and change the appearance of crooked or oddly shaped teeth.
