A porcelain crown—often referred to as a “cap”—is a dental restoration that covers a severely damaged or decayed tooth from the gumline up. Crowns protect teeth and restore their function. Well-made crowns have shape, color, and translucence that mimic natural teeth. With today’s technology cosmetic dentists, like Dr. Siny Thomas of Sugar Land, offer durable dental crowns that look entirely natural.
When Are Crowns Used?
A dental crown restores a damaged tooth or replaces a missing tooth.
Protect and restore the function of a tooth that is badly decayed, worn, or broken
Build a bridge with a series of connected crowns to replace one or more missing teeth
Restore an implant
Attach it to the top of a dental implant to replace the portion of a tooth above the gumline
The Strength and Beauty of Today’s Dental Ceramics
Porcelain is a translucent ceramic that is often layered for highly aesthetic results. Traditional all-porcelain crowns have a metal foundation to give them added support. In some cases a metal foundation is still used to strengthen ceramic crowns on back molar teeth. Advanced cosmetic dentists work with a lab to conceal the metal foundation, prevent it from showing through at the gumline, and keep the crown natural looking.
All-porcelain crowns lack the strength of newer ceramics. Dr. Thomas uses high-strength all-ceramic e.max and zirconia crowns.
If you need a crown for an anterior or premolar tooth, Dr. Thomas offers e.max, which has high-strength lithium disilicate as the foundation. Dr. Thomas’s master ceramist will finish the outer layer of the crown with porcelain. Your crown will have highly aesthetic color, translucence, and gloss that matches your natural teeth.
For molar teeth, Dr. Thomas uses zirconia, or zirconium dioxide, crowns. Layered zirconia provides added strength for a dental bridge. It’s characteristics include:
- Strength – Zirconium dioxide is so extraordinarily strong that it’s referred to as ceramic steel.
- Metal free – There is virtually no risk of metal allergies or sensitivities.
- Versatility – A ceramist can adapt it to match the opacity or translucency of your natural teeth.
What’s the Process?
Whether you’re receiving individual crowns, a dental bridge, or an implant crown, Dr. Thomas will ensure it is beautiful and functions well.
Cover a severely damaged tooth
If a tooth is severely decayed, worn, or broken, Dr. Thomas will remove the damage and taper your natural tooth so that the crown will fit over it. He will bond the crown to your tooth to protect it and restore its function.
Build a dental bridge
Dr. Thomas’s ceramist will join a series of crowns to build a bridge that replaces one or more missing teeth. Replacement teeth are suspended in the middle, and the ends will be placed over natural teeth to anchor the bridge. Dr. Thomas will taper the anchor teeth and cement the bridge to them.
Restore a dental implant
If you receive a dental implant to replace a missing tooth, Dr. Thomas will attach an abutment, or connector, to the implant. He will screw a dental crown onto the abutment to replace the portion of your tooth that shows above the gumline.
How to Care for Your Crowns
Even the most durable crowns require daily care if you want them to last.
- Daily floss between your teeth and brush them at least twice daily.
- If you clench or grind your teeth, Dr. Thomas offers a custom nightguard to help protect your crowns while you sleep.
- Avoid chewing very hard foods or using your teeth to bite or open hard objects.
- Keep your appointments for dental cleanings and exams. Dr. Thomas will ensure your crowns are functioning well.
