Metal Crowns vs. Porcelain Dental Crowns

When a tooth is too damaged for a filling but still can be saved, a dental crown is often the best restoration. At Alameda Dental in Aurora, CO, we place crowns to rebuild teeth weakened by decay, fractures, or large fillings. The two main categories patients consider are metal-based crowns and all-ceramic (porcelain) crowns. Each has distinct strengths, and the right choice depends on the tooth’s location, your bite, and your personal priorities.

01 / What a Dental Crown DoesWhat a Dental Crown Does

A crown is a full-coverage cap. We remove compromised enamel and dentin, shape the remaining tooth, and cement a custom-made restoration over it. The crown takes on the forces of chewing, protects the tooth from further damage, and restores its shape and function. Without a crown, a heavily filled or cracked tooth could split, sometimes leading to extraction.

02 / Metal Crowns: Proven StrengthMetal Crowns: Proven Strength

Metal crowns—made from gold alloys, palladium alloys, or base-metal alloys—are the most durable option. They require less tooth reduction because the metal is strong even when thin. We often consider metal crowns for back molars that aren’t visible when you smile, especially for patients with a strong bite, teeth grinding, or limited space. The benefits: metal rarely chips or breaks, it wears at a rate similar to natural enamel (so it’s gentle on opposing teeth), and it seals tightly against the tooth, reducing the risk of decay at the margin. The main drawback is aesthetics: metal doesn’t match tooth color, so we avoid all-metal crowns on front teeth.

Alloy Options

High-noble alloys (gold, platinum, palladium) are biocompatible, highly polishable, and cause minimal wear on opposing teeth. Base-metal alloys (nickel-chromium, cobalt-chromium) are strong and cost-effective, but nickel allergies exist in a small number of patients. We review your medical history before selecting an alloy.

Cementation

Because metal crowns block light, we use traditional cements that set without needing a curing light. This makes the process straightforward and can be helpful for patients who find it hard to keep their mouth open for long procedures.

03 / Porcelain-Fused-to-Metal Crowns: A Hybrid ApproachPorcelain-Fused-to-Metal Crowns: A Hybrid Approach

Porcelain-fused-to-metal (PFM) crowns combine a metal substructure with a tooth-colored porcelain overlay. They can be shade-matched to your teeth, so they work for both front and back applications. However, over time the porcelain can chip, revealing the dark metal underneath. Additionally, as gums recede, a gray line may become visible at the gumline. For patients with strong chewing habits or clenching, we discuss whether a PFM will hold up as well as a full-metal or newer high-strength ceramic crown.

Layering and Margin Placement

Our lab builds the porcelain in layers to mimic natural tooth depth and color. To hide the metal collar, the crown margin is often placed slightly below the gumline. For patients with thin gums, we may recommend a porcelain butt margin or an all-ceramic crown to avoid metal show-through.

04 / All-Porcelain and All-Ceramic Crowns: Natural AppearanceAll-Porcelain and All-Ceramic Crowns: Natural Appearance

All-porcelain crowns contain no metal. They are made from materials like feldspathic porcelain, leucite-reinforced glass ceramic, or lithium disilicate. Because there is no opaque metal core, light passes through similarly to a natural tooth, resulting in a lifelike appearance—especially at the gumline. These crowns are ideal for front teeth where aesthetics are critical, and they are also a good choice for anyone with a metal allergy. The absence of metal can also simplify medical imaging like MRIs. The limitation: traditional porcelain is more brittle than metal, so we evaluate your bite carefully before using all-porcelain on back teeth.

Feldspathic vs. Lithium Disilicate

Feldspathic porcelain offers excellent translucency for veneers or anterior crowns in low-stress areas. Lithium disilicate has significantly higher flexural strength and can be used for any single tooth. We choose based on the forces the tooth will face and your aesthetic goals.

Bonding Protocol

All-ceramic crowns require adhesive bonding with special resin cements and primers. We etch the inner surface, apply a ceramic primer, and then seat the crown. Light-curing is possible with translucent materials, ensuring a strong bond.

05 / Zirconia: The Metal-Free Strength OptionZirconia: The Metal-Free Strength Option

Zirconia is a ceramic that rivals metal in toughness. Monolithic zirconia crowns are extremely hard to break under normal chewing, and they can be precisely milled for an excellent fit. Layered zirconia crowns add a porcelain veneer for better aesthetics, though the outer porcelain can still chip under extreme force. At Alameda Dental, we suggest zirconia when a patient wants a metal-free crown but needs the strength for a molar. The color match is good, though very translucent zirconia may appear slightly more opaque than natural tooth enamel. We show you samples so you can see how it will look.

Translucency and Shade Matching

Zirconia comes in different translucency grades. We select a more translucent version for front teeth and can add external stains to enhance the color. For patients who show a lot of gumline when smiling, a higher translucency zirconia avoids a flat or artificial look.

Wear on Opposing Teeth

When polished, monolithic zirconia causes minimal wear on opposing enamel, making it suitable for patients who grind or have canine-guided bites.

06 / How We Help You DecideHow We Help You Decide

The Alameda Dental Team doesn’t use a one-size-fits-all material. We consider the remaining tooth structure, whether it has had a root canal, your gums, your bite, and your preferences for appearance, comfort, and budget. For a lower molar that doesn’t show and supports heavy chewing, a metal or zirconia crown may serve you longest. For an upper front tooth with a high smile line, an all-ceramic lithium disilicate crown is often the best aesthetic choice. For teeth in between—like a premolar that shows when you laugh—layered zirconia or a PFM can offer a practical balance.

07 / The Crown ProcedureThe Crown Procedure

The steps are similar regardless of material. After numbing the area, we remove decay and old fillings, shape the tooth to create space for the crown, and take a precise impression. We place a temporary crown to protect the tooth while the lab fabricates your permanent crown. At the second visit, we remove the temporary, try in the new crown, check the fit and bite, and cement or bond it in place. Metal and PFM crowns are typically cemented with resin-modified glass ionomer or adhesive resin. All-ceramic crowns require special bonding agents for a durable chemical bond.

Temporary Crown Care

Your temporary crown is held in place with a gentle cement. Avoid sticky or hard foods, and when flossing, pull the floss out from the side rather than snapping it upward. If the temporary comes loose, call us right away—leaving the prepared tooth exposed can cause sensitivity or shifting.

08 / Keeping Your Crown HealthyKeeping Your Crown Healthy

No crown is maintenance-free. Brush twice a day, clean between your teeth daily, and keep up with professional cleanings. The seam where the crown meets the tooth is a spot where plaque can build up, potentially causing decay or gum problems. With good care, crowns can provide many years of service. Metal crowns are known for long-term durability. PFMs have a solid track record, though the porcelain may eventually need repair. Modern ceramics, when bonded correctly, also perform well over time. If you grind your teeth, we strongly recommend a night guard to protect your investment.

Home Care Tools

We suggest an electric toothbrush with a pressure sensor, a water flosser for tight contacts, and a low-abrasive fluoride toothpaste. After we deliver your crown, we’ll give you a guide specific to your material.

Professional Maintenance

During your regular hygiene visits, we use gentle cleaning methods to avoid scratching the crown surface and take X-rays to check the margin for early signs of trouble.

01 / When to Consider ReplacementWhen to Consider Replacement

Crowns don’t last forever. We evaluate them at each checkup for wear, open margins, decay, or cracks. Signs like biting sensitivity, a rough spot on the crown, or a change in how it feels are reasons to call us. Early attention can often save the tooth.

02 / Common MisconceptionsCommon Misconceptions

Myth: Crowns prevent cavities. Fact: The tooth underneath can still decay if plaque builds up at the margin. Myth: All-ceramic crowns are fragile. Fact: Modern lithium disilicate and zirconia crowns are very strong—many times tougher than traditional porcelain. Myth: Metal crowns set off airport metal detectors. Fact: Dental alloys contain minimal ferromagnetic metals and typically don’t trigger alarms. Myth: You can’t have an MRI with a crown. Fact: All common crown materials—gold, PFM, zirconia, lithium disilicate—are MRI-safe.

03 / Questions to Ask During Your ConsultationQuestions to Ask During Your Consultation

• Which material do you recommend for my specific tooth and why? - What kind of durability can I expect with each option given my bite and habits? - Would a night guard or occlusal guard help extend the crown’s life? - How will my dental insurance apply, and what will my out-of-pocket cost be? - What happens if the crown chips or comes loose? - Can I see samples of how each material will look in my mouth? - How will the crown interact with any existing fillings or implants? We answer all questions chairside and provide a written summary for your records.

04 / Special ConsiderationsSpecial Considerations

Children rarely get full-coverage crowns on permanent teeth unless trauma or severe decay is present. For baby teeth, stainless steel crowns are a common temporary solution. Seniors with dry mouth need extra fluoride to protect crown margins. Pregnant patients can usually have a crown placed after the first trimester; we may delay elective treatment if the tooth isn’t causing problems. Patients undergoing chemotherapy or radiation may need metal-free restorations to avoid potential irritation. For severe teeth grinders, a zirconia crown paired with a custom night guard often works well. Teeth with root canals are more brittle, so we may place a post before the crown; material choice then depends on how much tooth remains.

05 / Long-Term OutlookLong-Term Outlook

With good oral hygiene and regular dental visits, crowns can serve you well for many years. Factors that can shorten a crown’s life include smoking, uncontrolled diabetes, and poor hygiene. We screen for these and coordinate with your physician if needed.

06 / Cost and InsuranceCost and Insurance

The price of a crown varies by material, the complexity of your case, and your insurance coverage. We file claims electronically and can provide a pre-treatment estimate so you know what to expect. There are no hidden fees.

07 / After Your Crown Is PlacedAfter Your Crown Is Placed

It’s normal to have some temperature sensitivity for a day or two after the procedure. If it lasts more than a week, call us for an adjustment. You can brush and floss normally right away, but avoid very sticky foods for the first 24 hours to let the cement fully set. We’ll schedule a follow-up visit to check your bite and make sure your gums are healing well.

08 / Comparing Metal, PFM, and Zirconia Side by SideComparing Metal, PFM, and Zirconia Side by Side

• Metal crowns: extreme durability, minimal tooth reduction, no cosmetic value. Ideal for hidden molars. - PFM crowns: good strength with a tooth-colored exterior, but possible metal show-through and porcelain chipping. - Zirconia crowns: high strength and aesthetic, no metal, can be used anywhere. Layered versions offer better color at a slight risk of porcelain chipping.

09 / FAQFAQ

Q: Will my crown look fake? A: Modern ceramics are layered to mimic natural translucency. We match shade, texture, and even subtle imperfections so the crown blends in. Q: How soon can I eat normally? A: After the numbness wears off, you can eat. Just avoid sticky foods for a day while the cement fully sets. Q: Can I whiten a crowned tooth? A: Crowns don’t respond to whitening agents. If you plan to whiten, do it beforehand so we can match the new shade. Q: Is the procedure reversible? A: No. Preparing a tooth for a crown removes enamel permanently. That’s why we only recommend it when a filling or other restoration won’t suffice. Q: Can another dentist care for my crown if I move? A: Yes. We use standard materials and techniques, so any dentist can provide future care. Q: Do crowns cause bad breath? A: Only if plaque accumulates at the margin. Good home care and regular cleanings prevent odor. Q: Can I chew gum with a crown? A: Sugar-free gum is fine; avoid sticky candies that could pull on the crown.
