What is a dental crown?

A dental crown is a full-coverage restoration that sits over a damaged, root-canal-treated or heavily filled tooth. Unlike a veneer, which covers only the front face of a tooth (roughly 25% of its surface), a crown wraps the tooth 360° — restoring its natural shape, protecting it from further fracture, and returning full chewing strength.

Dentists in Hoi An and Da Nang prepare a crown by reducing the existing tooth by about 1.5–2 mm in every direction. The crown is then milled from a digital scan and cemented in place. Done correctly with modern zirconia, the finished tooth looks, feels and chews like the original — often for 20 years or more.

Crown materials compared

The two clinics we profile in this guide offer the full modern spectrum. Use this table to get a feel for what each material does best — the right choice depends on which tooth, how strong your bite is, and how much aesthetic matters.

Zirconia types explained

Monolithic zirconia (full zirconia)

A single solid block of zirconia milled into a crown — no porcelain layer on top. It’s the strongest crown material on the market, measured at about 1,200 MPa of flexural strength. Modern multi-layer zirconia blocks now grade colour and translucency through the block, so aesthetics on back teeth are genuinely good.

• Best for: molars, premolars, grinders, strong-bite patients, implant crowns on back teeth
• Risk: very low — monolithic zirconia almost never fractures itself
• Hoi An price: USD 280–380 per tooth

Layered zirconia (zirconia + porcelain)

A zirconia core does the structural work; a hand-layered feldspathic porcelain coat on the visible face gives a more translucent, lifelike finish. This is what most Hoi An clinics recommend for front teeth when the patient wants maximum aesthetics plus zirconia-level durability.

• Best for: front teeth, canines, cases where the smile zone is critical
• Risk: the porcelain overlay can chip on very heavy bites (rare with correct thickness and occlusion design)
• Hoi An price: USD 380–480 per tooth

Lava zirconia (3M proprietary)

Lava is 3M’s branded zirconia line — stricter quality control, more consistent translucency block-to-block, and digitally optimised for milling workflows. An Tam Smile Dental Clinic Hoi An specialises in Lava-branded porcelain crowns and uses this as their premium option.

• Best for: premium cases, full-smile makeovers, patients who want a recognised international brand
• Hoi An price: USD 380–500 per tooth

Home-market savings table (single zirconia crown)

All figures are for a single zirconia crown including digital scanning, temporary, try-in and final cementation. Home-market prices are national averages collected from dental association fee guides and major insurer reimbursement tables for 2026.

Break-even for a single crown is almost immediate once you factor in the flight. For anyone with 2–4 crowns, a Hoi An trip — beachfront hotel, lantern-lit Ancient Town evenings, tailored clothing, the lot — usually still comes in under what a single crown would cost at home.

When you need a crown (and not a veneer or filling)

Crowns are structural, not cosmetic. A dentist will recommend one when the tooth can no longer support itself with a filling or veneer alone.

• Large fillings that have broken or that exceed about half the tooth’s structure
• After root canal treatment — root-canal-treated teeth become brittle and almost always need full coverage
• Cracked tooth syndrome (a vertical crack causing pain on biting)
• Severely worn teeth from bruxism (night grinding)
• Cosmetic transformation of a misshapen tooth where a veneer would be too thin to survive
• Supporting a bridge as one of the abutment teeth
• Covering a dental implant (the implant crown is the visible part of an implant)

The 5-day crown protocol in Hoi An

Standard digital workflow at both Picasso Da Nang and An Tam Smile Hoi An. No messy impression material — everything is driven off a 3Shape or Cerec intraoral scan.

Same-day crowns: Cerec at Picasso Da Nang

Picasso Dental Clinic Da Nang operates an in-house Cerec milling unit. For a single zirconia or e.max crown, this compresses the whole protocol into one visit:

• Morning: digital X-ray, exam, preparation and intraoral scan
• Midday: crown milled on-site (40–60 minutes) and glazed
• Afternoon: try-in, bite adjustment, permanent cementation
• Cost: same price as the 5-day protocol — USD 280–450 depending on material

Same-day Cerec is the right call if you’re in Hoi An for a short cruise stop, need an emergency crown replacement, or simply want everything finished in one day. For bridges, front-teeth layered zirconia or full-mouth cases, the 5-day protocol is still preferred because the technician needs overnight time for layering and glazing.

Top 2 clinics for crowns in Hoi An & Da Nang

Which clinic is right for you?

Aftercare & longevity

The first 24 hours

• Avoid very hard foods until the cement has fully cured (24 hours)
• Brush and floss normally — just gently around the new margin
• Use a non-abrasive toothpaste (avoid whitening pastes with high RDA)
• Mild bite sensitivity for 1–3 days is normal

Long-term care

• Skip chewing ice, hard candy, bone, seafood shells and popcorn kernels
• Annual dental check-ups
• Night guard if you have any history of bruxism — this is the single biggest predictor of zirconia longevity
• Flossing around crowned teeth prevents decay under the margin (the #1 failure mode)

How long do zirconia crowns last?

Modern zirconia crowns have an average lifespan of 15–25 years with good home care. Peer-reviewed studies show 95%+ survival at 10 years for monolithic zirconia. The common failure modes, in order of frequency, are:

1. Cementation failure — crown loosens, can usually just be re-cemented
2. Porcelain chipping — only a risk in layered zirconia, not monolithic
3. Recurrent decay under the margin — driven entirely by oral hygiene lapses
4. Zirconia fracture — extremely rare in monolithic zirconia

Common concerns answered

Will the crown look natural?

Modern multi-layer monolithic zirconia has excellent aesthetics for back teeth — light passes through the block in the same graded way it does through a natural tooth. For front teeth, layered zirconia or Ivoclar e.max is the preferred choice because the outer porcelain layer gives superior translucency.

Will I feel the crown is there?

Within 2–3 days, the vast majority of patients report forgetting they have it. The bite adjustment on Day 5 is the critical step — if the crown is even 0.1 mm high, you’ll feel it permanently. Both our clinics verify occlusion with articulating paper and a digital bite check.

Does it hurt?

Preparation is under local anaesthesia, so Day 1 is painless. Some sensitivity for 1–3 days post-preparation while the temporary is in place is normal. Once the permanent crown is cemented, most patients report immediate comfort.

Can I have crowns on implants?

Yes — the crown is the final prosthetic element of an implant. If you’re already planning implants in Hoi An, the same clinic usually fabricates the implant crown (zirconia is typically preferred for strength and gum-friendly biocompatibility).

What if I need a root canal first?

Root canal is always done before the crown. Plan for roughly 7–10 days total if both treatments are needed on the same tooth in one trip. Picasso Da Nang offers combined root-canal + crown packages under a single treatment plan.
