When more than 50% of the tooth structure is compromised, a filling cannot adequately support the remaining walls against bite forces. A crown encases and reinforces the entire tooth. Additionally, teeth with root canals, large cracks, or cusp fractures typically require crowns regardless of cavity size because the structural integrity is compromised beyond what a filling can restore.

The best option depends on the condition of the adjacent teeth, available bone, medical history, timeline, and budget. If the adjacent teeth already need crowns, a bridge uses that treatment. If the adjacent teeth are healthy and intact, an implant avoids preparing them. Both options are presented with pros and cons during your consultation.

Digital scanners capture 3D tooth geometry at sub-millimeter accuracy without the distortion inherent in traditional putty impressions. The digital file transmits directly to CAD software, eliminating stone model pouring errors. The result is consistently better marginal fit — gaps under 50 microns versus 100+ microns with traditional techniques — which translates to better seal, less cement washout, and longer restoration lifespan.

Full-contour zirconia (3Y-TZP or 5Y-TZP) is the strongest dental ceramic, with flexural strength of 900 to 1200 MPa. This exceeds the strength of natural enamel and all other dental ceramics. Zirconia crowns are the material of choice for patients with heavy bite forces, bruxism, or posterior teeth under maximum occlusal loading.

Yes. IV sedation is available at ADSC for patients with dental anxiety or for extended appointments involving multiple crown preparations. Sedation allows comfortable completion of complex procedures that might otherwise require multiple shorter visits. You rest comfortably while the work is completed precisely.

Signs a crown may need replacement: visible dark line at the gumline (metal showing through), rough or chipped ceramic surface, pain or sensitivity, loose fit, recurrent decay visible on X-ray at the margin, or gum inflammation that does not resolve with improved hygiene. Regular dental evaluations detect these issues before they cause crown failure.

Lab crowns are handcrafted by technicians who layer porcelain for maximum aesthetics — ideal for anterior teeth. Same-day crowns are milled from monolithic ceramic blocks chairside — excellent for posterior teeth and patients who prefer single-visit treatment. Both produce durable, well-fitting restorations. The choice depends on aesthetic demands and scheduling preferences.

Yes. Implant-supported bridges are anchored to dental implants rather than natural teeth. This avoids preparing healthy adjacent teeth and provides bone-stimulating support in the edentulous area. Implant bridges can span larger gaps than conventional bridges and distribute forces through the implant-bone interface rather than loading natural teeth.

Individual crowns are flossed normally. Bridges require special tools to clean beneath the pontic: floss threaders, Superfloss (with a stiff end and spongy section), interdental brushes, or water flossers. Daily cleaning under the bridge prevents plaque accumulation that causes abutment decay — the primary cause of bridge failure.

Ceramic fracture results from excessive force (biting hard objects), inadequate material thickness (from insufficient tooth preparation), poor material selection for the clinical situation, or uncontrolled bruxism without nightguard protection. Properly designed crowns with appropriate material selection and adequate thickness rarely fracture under normal function.

ADSC stands behind the quality of restorative work. Specific warranty terms are discussed during the treatment planning appointment. Crown and bridge longevity depends on proper maintenance — regular dental visits, good oral hygiene, and nightguard wear when recommended. Restorations that fail due to manufacturing or technical issues are addressed promptly.

Multiple crowns can be prepared in a single appointment, limited primarily by patient comfort and appointment duration. It is common to prepare four to six crowns in one quadrant during a single session. IV sedation facilitates longer appointments for patients needing extensive crown work across multiple quadrants.

All-ceramic crowns and bridges (zirconia, lithium disilicate) produce no MRI artifacts and are completely compatible with medical imaging. Porcelain-fused-to-metal (PFM) restorations may produce minor image distortion in the immediate vicinity. Dental restorations do not prevent or contraindicate MRI scanning in any case.

An existing bridge cannot be extended. If an additional tooth adjacent to the bridge is lost, the bridge must be removed and a new, longer bridge designed — or an implant placed in the new extraction site. This is one reason treatment planning considers the long-term prognosis of adjacent teeth when designing bridges.

Individual crowns: $1,200 to $1,800. Three-unit bridges: $3,600 to $5,400. Costs vary with material selection and case complexity. Most insurance plans cover these procedures at 50% after the deductible with typical annual maximum benefit of $1,500 to $2,500.
