FULL PORCELAIN CROWNS IN GRANADA HILLS

When does a tooth need a crown?

A crown is the answer when a tooth's structure is compromised and a filling can't restore it reliably. That includes a tooth that's:

• Cracked, broken, or heavily worn. Once a fracture line runs through a tooth, a filling doesn't hold it together — a crown wraps the whole tooth and takes the chewing force off the crack.
• More filling than tooth. A large old filling that's failing, or a tooth with so little natural structure left that a new filling has nothing to anchor to.
• Root-canal treated. A tooth without its nerve becomes brittle. Full coverage is what protects it from fracturing under chewing.
• Severely discolored or misshapen in a way a veneer can't address — usually because the tooth is also damaged or heavily restored. (If the tooth is healthy and the concern is only appearance, a veneer is the more conservative choice; the veneers vs. crowns page walks through that decision.)

The recommendation comes from the X-ray and the exam, not from the mirror. A tooth that looks fine on top can have a crack that makes a crown the right call; a tooth you assumed was beyond saving may need much less.

Why "full porcelain" matters

For decades the standard crown was porcelain fused to a metal base. Strong, but with two problems: the metal blocks light, so the crown looks flat and opaque next to natural teeth, and as gums recede over the years the metal edge shows as a grey line at the gumline.

Viva Smile no longer places metal-based crowns at all. Every crown is full ceramic. Light passes into it and reflects back the way it does through enamel, there's no metal to show at the gum, and modern ceramics have caught up on the strength the metal used to provide — in some cases surpassed it.

The right porcelain for the right tooth

"Porcelain" isn't one material. Viva Smile works with a range of dental ceramics, and the choice for your crown is made deliberately, because the two things a crown has to do — survive chewing and look like a tooth — pull in different directions.

Back teeth: strength first.

Molars and premolars take the full force of chewing. For these, the crown is made from zirconia or a zirconia-based ceramic — materials with a flexural strength of 1,200 MPa or more, roughly ten times that of the most beautiful glass ceramics. A back-tooth crown is rarely seen and constantly loaded, so strength wins.

Front teeth: light first.

Incisors and canines carry far less force but are seen every time you speak. For these, the crown is made from ceramics chosen for translucency and how they handle light — lithium disilicate (E-Max), lithium silicate, or feldspathic porcelain. These are the materials that let a single crown disappear among natural teeth. They're not strong enough for a molar, and they're not asked to be.

Materials keep evolving. New ceramics arrive that are both stronger and more lifelike than what came before, and the practice adopts them as they prove themselves. The point isn't a brand name. It's that the material on your tooth is the one suited to what that tooth has to do.

Same-day crowns: one visit, no temporary

For many single crowns, the whole thing happens in one appointment. The tooth is prepared, scanned digitally, and the crown is designed on screen and milled from a solid block of ceramic in the practice's own Planmeca mill — then fitted, adjusted, and cemented while you wait. No impression putty, no temporary crown, no two-week gap, no second visit.

Same-day crowns are milled from lithium disilicate or leucite-reinforced ceramic, which suit single teeth well. Whether your crown can be done same-day depends on three things: the condition of the tooth, the time available, and your preference. Single-unit crowns anywhere in the mouth may qualify.

When a crown goes to the lab instead.

Cases involving the smile zone with an aesthetic goal — where several front teeth are being restored to look like one designed smile — go to the lab, where a ceramist layers and characterizes the porcelain by hand. These cases take two visits, with a temporary in between, and the extra time is what buys a result no mill can produce alone.

Crowns in the smile zone: when design comes first

If a case involves more than two crowns among the visible front teeth, it's treated like a veneer case: it runs through the Digital Smile Design process. The smile is designed digitally against your face, you wear a 3D-printed mockup on Vogue Day and approve the result, and the crowns are then made to that approved design. Several crowns in a row are a smile, not a repair, and they're designed as one.

A single crown in the front is handled differently — no full smile design, but the same care in shade matching, translucency, and shape so it disappears among its neighbors. Dr. Baghdasaryan is an Accredited Member of the American Academy of Cosmetic Dentistry, a credential earned through documented cosmetic casework judged by a peer panel and held by fewer than 350 dentists worldwide. A single front crown that can't be picked out in the mirror is the standard that credential represents.

What the appointment is like

Preparation.

The area is numbed — with The Wand, so the injection itself is barely felt — and the tooth is reshaped to make room for the crown. You feel pressure, not pain. The tooth is then scanned with an intraoral camera; no trays, no putty.

Same-day path.

While you wait, the crown is designed and milled. It's tried in, checked for fit and bite, the shade is confirmed against your other teeth, and it's cemented. You leave with the finished crown.

Lab path.

A temporary crown is placed and you return in about two to three weeks for the permanent one, which is checked and adjusted the same way before cementing.

Afterward.

The tooth may be sensitive to temperature for a few days and then settles. If you had a temporary, avoid sticky or very hard foods until the permanent crown is in. Once it's cemented, you eat normally within a day or two.

Caring for a porcelain crown

A crown is cared for like the tooth it covers: brush, floss around it, keep your regular cleanings. The porcelain itself can't decay, but the tooth underneath and the gum around it still can, which is why the margin where crown meets tooth is where good hygiene matters most. If you grind your teeth at night, a night guard protects the crown — and the teeth around it — from the forces that chip ceramic. Looked after this way, a full porcelain crown is a long-lasting restoration.

Ready to find out if your tooth needs a crown?

The answer lives in the X-ray, not the mirror, and it's often less than people fear. A dental exam identifies what the tooth actually needs — a crown, something more conservative, or nothing yet — and whether it can be done the same day. Book online or call (818) 900-2800. A free Zoom consultation with Dr. Baghdasaryan is also available if you'd like to talk it through first, though what a specific tooth needs is a question your X-rays will answer.
