What to Expect with Dental Crowns

A dental crown is a restorative cover that sits over the top of a tooth — usually porcelain or resin — protecting the tooth while restoring its color, shape, and strength. Crowns are typically recommended for large cavities, worn or weakened teeth, or badly discolored teeth that need covering.

The Two-Visit Procedure

Visit one. The dentist numbs the area, removes any decay, shapes the tooth so the crown will fit, takes an impression or digital scan, sends it to the lab, and places a temporary crown.

Visit two, about two weeks later. The temporary is removed, the permanent crown is checked for fit, color, and bite, and then cemented into place.

How Long Do Crowns Last

About fifteen years on average with good care, and twenty-five to thirty years is not uncommon. Longevity depends on oral hygiene and daily wear.

Problems That Can Develop

Discomfort or sensitivity after placement is normal as anesthesia wears off, and a sensitive-toothpaste regimen helps if the nerve is still present. Pain when biting down often means the crown is slightly too high — an easy adjustment.

Chipped crown. Small chips can be repaired. Large or repeated chips may require replacement.

Loose crown. Cement can wash out over time, allowing bacteria in and causing decay underneath. Call promptly if a crown feels loose.

Crown falls off. Possible from improper fit or worn cement. The crown can often be re-cemented or remade.

Allergic reaction. Extremely rare reaction to metal or porcelain alloys.

Dark line at the gum line. Normal in porcelain-fused-to-metal crowns where the metal substructure shows through. Not harmful.

Aftercare

With a temporary crown, avoid chewy or sticky foods, hard foods, extremely hot or cold foods, and tough foods. Chew on the opposite side and slide floss out sideways rather than lifting it up.

With a permanent crown, avoid hard or crunchy foods, very sticky foods, chewing ice, and raw vegetables when possible. Don't use your teeth as tools.

To preserve the crown, brush and floss at least twice daily with a soft-bristled brush and non-abrasive fluoride toothpaste, attend dental checkups every six months, and limit dark foods and drinks that can stain the porcelain at the edge over time.

Cost

Cost varies by material and location. Porcelain crowns are usually the most expensive, while gold or porcelain-fused-to-metal options are typically the most affordable. Call AVF Dental Group at (949) 360-9700 to discuss what fits your situation.
