If your dentist has told you a tooth needs a crown, you’ve likely started wondering what it will be made of. An all-ceramic crown in Wilmington, NC gives you a strong, natural-looking restoration with no metal involved. No nickel, no dark line at the gumline, and no alloy your body might react to. Just a material that works with your biology rather than against it.
What Is an All-Ceramic Crown in Wilmington, NC?
An all-ceramic crown is a dental cap made entirely from tooth-colored ceramic material, most often zirconia (a high-strength ceramic) or lithium disilicate (a glass-ceramic prized for its translucency). The entire crown, from the inner core to the outer surface, is ceramic. Nothing metallic is involved at any stage.
That sets it apart from two older options you may have heard of.
Porcelain-Fused-to-Metal (PFM) Crowns
A porcelain-fused-to-metal crown, often called a PFM, has a metal shell underneath a porcelain coating. The metal adds strength, but it creates real problems over time. As gum tissue recedes, a gray metal margin appears at the base of the crown. Some patients also react to specific alloys in the metal core, including nickel or beryllium. According to the American Contact Dermatitis Society, nickel is among the most common contact allergens, affecting an estimated 10 to 15 percent of the population.
Full-Metal and Metal-Backed Crowns
Full-metal crowns (gold or base-metal alloys) are durable, but they’re obviously visible and contain metals that some patients prefer to avoid. A biocompatible material is one the body tolerates without triggering inflammation, immune responses, or sensitivity reactions. Zirconia and lithium disilicate both meet that standard.
Why Holistic Patients Choose Metal-Free Crowns
Patients who come to a holistic dental practice are usually already thinking about the whole-body picture. Many are the same patients who’ve asked about metal-free dentistry options or who are having old amalgam fillings replaced. A crown is a long-term restoration that stays in your mouth for 10 to 20 years or more, so what it’s made of matters over that timeline.
The biocompatibility case for all-ceramic crowns is clear. Zirconia and lithium disilicate are chemically stable. They don’t corrode, they don’t release metal ions into your saliva, and they have a strong clinical track record of tissue tolerance. A 2022 review in the Journal of Prosthetic Dentistry found that zirconia-based restorations showed favorable soft-tissue responses compared to metal-ceramic alternatives, with lower rates of marginal inflammation.
For patients who’ve already taken steps to reduce metal exposure, such as through the SMART protocol for mercury-safe removal, placing a metal-cored crown afterward contradicts the whole approach. Biological dentistry aims for consistency across every treatment decision.
Aesthetics Are a Real Benefit, Not Just a Bonus
All-ceramic crowns transmit light the way natural enamel does. That quality, called translucency, means the crown won’t look flat or artificial under different lighting. PFM crowns block light because of the opaque metal underneath, which is why they can look noticeably different from natural teeth, especially in photographs.
For front teeth, this difference is visible in everyday conversation. For back teeth, appearance matters less, but the biocompatibility argument still holds.
How All-Ceramic Crowns Are Placed: What to Expect
The process for getting an all-ceramic crown in Wilmington follows the same general steps as any crown procedure, with a few refinements a holistic practice typically adds.
- Preparation visit. Your dentist numbs the area and reshapes the tooth to create space for the crown. A digital scan or impression captures the exact dimensions of the prepared tooth and your surrounding bite.
- Temporary crown. A temporary crown protects the tooth while your permanent ceramic crown is fabricated, typically at a dental lab with expertise in all-ceramic restorations.
- Shade matching. Your dentist notes the color and translucency of your adjacent teeth so the ceramic crown blends naturally.
- Cementation. At the second visit, the fit and bite are verified before the crown is bonded into place with a biocompatible dental adhesive.
- Follow-up. Minor bite adjustments are common in the first week or two as your mouth adapts.
Some practices use same-day milling technology (CAD/CAM) to fabricate the crown chairside. The result is still all-ceramic; the difference is only in how it’s made.
Are All-Ceramic Crowns Strong Enough for Back Teeth?
This is one of the most common questions, and the short answer is yes. Older all-porcelain crowns did have fracture issues on molars. Zirconia changed that picture significantly. Zirconia has a flexural strength (the pressure required to crack the material) of roughly 900 to 1,200 MPa in monolithic form. That’s well above the bite force most people generate. PFM crowns typically fall in the 400 to 600 MPa range for the porcelain layer. The National Institutes of Health has documented zirconia’s mechanical properties in multiple peer-reviewed summaries.
According to a clinical review published on PubMed, monolithic zirconia crowns placed on posterior teeth showed survival rates above 96 percent at five years. “Ceramic” no longer means fragile.
For heavy grinders, your dentist may recommend a specific zirconia formulation with added thickness, or a nightguard to protect the restoration. Both are practical, not unusual.
Ceramic Crowns vs. PFM: A Plain-Language Comparison
Here’s how the two options stack up on the questions patients actually raise:
- Biocompatibility. All-ceramic wins. No metal ions, no corrosion products, no alloy sensitivities.
- Appearance. All-ceramic wins. Light transmission through the material mimics natural enamel in a way PFM cannot replicate.
- Longevity. Both can last 15 or more years with good home care. Zirconia has strong long-term data; PFM has a longer track record simply because it’s older technology.
- Gumline aesthetics over time. All-ceramic wins. No dark metal margin appears if gums recede.
- Cost. All-ceramic crowns often cost more up front than PFM. Insurance coverage varies. The practice team can walk you through what your plan covers before treatment begins.
- Repairability. PFM chips can sometimes be repaired chairside. All-ceramic crowns that chip significantly usually require replacement, though this is uncommon with zirconia.

What Makes a Crown Truly Holistic
The material choice is only part of the picture. A holistic approach to crown placement also includes:
- Using biocompatible bonding agents that avoid known sensitizers
- Avoiding unnecessary pulp exposure during tooth preparation, which can stress the nerve
- Carefully evaluating the bite relationship, since a crown that disrupts the bite can create jaw tension and even affect sleep quality
- Discussing root health before placing any restoration, so you’re not sealing a problem in
Holistic dentistry treats each tooth as part of a larger system. A crown decision connects to your bite, your jaw muscles, your immune response, and your long-term comfort, not just the shape of one tooth. This guide to biological dentistry in Wilmington explains the philosophy in practical terms if you want to understand how this kind of care differs from a conventional approach.
For reference, the International Academy of Oral Medicine and Toxicology (IAOMT) publishes position papers on biocompatible materials and safe dental practices that inform how holistic practices approach material selection.
Frequently Asked Questions
Are all-ceramic crowns safe for people with metal sensitivities?
Yes. All-ceramic crowns contain no metals, making them a strong option for anyone with known reactions to dental alloys such as nickel, cobalt, or palladium. Zirconia and lithium disilicate are chemically inert materials with no documented history of allergic sensitization in the dental literature. If you have a history of contact reactions to metal jewelry or previous dental work, a ceramic crown removes that variable entirely.
How long does an all-ceramic crown last?
With good oral hygiene and regular dental visits, most all-ceramic crowns, especially zirconia, last 15 to 20 years or longer. Longevity depends on how the crown was fitted, your bite pattern, and whether you grind your teeth. Heavy grinding puts more stress on any crown material, and your dentist may recommend a nightguard to protect the restoration.
Is an all-ceramic crown more expensive than a PFM crown?
All-ceramic crowns typically cost more than PFM crowns, though pricing varies by material (zirconia vs. lithium disilicate), lab fees, and the complexity of the case. Many dental insurance plans now cover all-ceramic crowns at the same rate as PFM for most teeth. The practice team at Wilmington Holistic Dentistry can review your specific coverage before treatment begins so there are no surprises.
Can I replace my old PFM or metal crown with a ceramic one?
In many cases, yes. Old crowns can be removed and replaced with an all-ceramic crown, provided the underlying tooth structure is still healthy. If the tooth has changed significantly since the original crown was placed, your dentist will assess whether additional work (such as building up the tooth structure) is needed first. Replacing a metal-based crown with a ceramic alternative is a common request at holistic practices.
What is the difference between a zirconia crown and a porcelain crown?
Zirconia is a type of ceramic, so the terms overlap in everyday conversation. In clinical terms, zirconia crowns are made from zirconium dioxide, which is extremely strong and best suited for back teeth. Porcelain crowns (often lithium disilicate or feldspathic porcelain) are more translucent and ideal for front teeth where aesthetics are the priority. Your dentist will recommend one based on where the tooth sits in your mouth and how much biting force it bears.
Does getting a crown hurt?
The preparation visit uses local anesthesia, so the procedure itself is not painful. Some sensitivity to pressure or temperature is normal in the days after preparation, while the temporary crown is in place. Once the permanent ceramic crown is cemented and the bite is balanced, most patients have no ongoing discomfort. If sensitivity persists past two weeks, contact your dentist, since that can occasionally signal a nerve reaction worth evaluating.
