Your dentist says the tooth needs a crown. That comes with a plan, usually more than one appointment, and a set of words nobody explains. Here is what a dental crown procedure actually involves, appointment by appointment.

What a Crown Is, and What It Does
A crown covers a tooth to help restore it to its normal shape and size, and can make the tooth stronger and improve its appearance. A dental school says it more usefully: crowns are artificial replacements for missing tooth structure.
A crown is not a coating added on top of a whole tooth; it replaces the part that is already gone.
Dentistry uses five groups of material for this kind of restoration: noble metal alloys, base metal alloys, ceramics, resin-based composites and metal-ceramics. Crowns here are ceramic, which looks like a tooth, though the ADA notes ceramics can fracture and chip.
That also explains the timeline. A filling is direct, generally done in one visit; a crown is indirect, fabricated in a laboratory from impressions of the tooth, so it usually requires several visits.
Why Your Dentist Recommends One
In dentistry generally, the ADA lists the reasons a tooth gets crowned:
- to strengthen a tooth with a large filling, when there isn’t enough tooth remaining to hold the filling;
- to protect a weak tooth from breaking, or restore one that’s already broken;
- to attach a bridge;
- to cover a dental implant;
- to cover a tooth that is discolored or badly shaped.
A dental school adds the case most people arrive with: a tooth that is cracked, or where a filling has grown so large it compromises the strength of the tooth. In dentistry generally, a crown is also what restores a tooth after root canal treatment.
The Preparation Visit
Checking the tooth. The visit starts with the tooth itself. In the clinical literature the sequence runs assessment first, then preparation and the impression, then cementing the crown at a later visit. Your dentist may take an X-ray as part of that check.
Numbing. Local anesthesia is medication used to prevent pain in a specific area of your mouth during treatment, and the ADA names this procedure specifically: injectable anesthetics may be used in preparing teeth for crowns. Your dentist may apply a topical anesthetic to numb an area before injecting the local anesthetic.
Shaping the tooth. A crown goes over the tooth after it has been prepared, the profession’s word for shaping it down so the crown fits over it.
This is the part nobody tells you about. Two laboratory studies measuring preparations on model teeth found 67.5% to 75.6% of the coronal tooth structure removed on back teeth, where complete crowns took more than any other design tested, and about 63% to 72% on front teeth. Those are laboratory figures on resin teeth from 2002, not a clinical average. The honest point stands: this is not a thin layer. The same authors note the trade-off: conserving sound tooth structure helps preserve tooth vitality and reduce postoperative sensitivity.
The impression and the shade. Each crown is custom designed from an impression or a scan, and the color is matched to the teeth around it, which matters most on a front tooth, where a slight variation is obvious.
The temporary. Replacement teeth usually take some time to make, so in the meantime a temporary crown protects the tooth and lets you eat and speak normally.

Digital Impressions Instead of a Tray of Putty
Crowns at Icon Dental Center are made from fully digital impressions. A dental school puts the difference plainly: no longer do patients have to experience the mouth full of impression material formerly required for crowns.
The evidence backs the comfort, not a quality claim. A systematic review of 17 studies found scanning faster than conventional impressions, and that it can improve the patient experience measured by overall preference and comfort. A 2025 meta-analysis of 18 studies of implant-supported work found the same pattern, with no significant difference for pain.
On fit, the honest answer is that both work. A meta-analysis of single-unit ceramic crowns made both ways measured differences of a few to a few dozen micrometers and concluded there is no significant difference between the impression systems. Digital scanning is more comfortable. It does not make a better crown.
While the Lab Makes the Crown
The impression or scan goes to a dental laboratory, where the crown is made.
No authoritative source publishes a standard lab turnaround, and a number you read elsewhere is not coming from one. The ADA will say only that replacement teeth take some time to make. You will get actual dates at your appointment.
The Fitting Visit
The temporary comes off and the new crown is tried on the tooth. Fit and bite are checked before the crown is cemented for good, and that check is not a formality: adjusting a crown by grinding it to fit can lead to stress concentrations.
Once it fits, the crown is fixed in place. Indirect restorations can be conventionally cemented or may require adhesive bonding to the tooth, depending on the material and the situation.
What About Same-Day Crowns?
People search for one-visit crowns, so here is the straight answer: crowns at Icon Dental Center are lab-made, and they are not same-day.
Chairside systems exist in dentistry. A dental school describes its own: procedures that used to need an outside dental laboratory are now possible in a few days, or even the same day. The published comparisons of the two are mixed. One systematic review of 14 clinical studies found a 1.84 times higher failure risk for CAD/CAM manufacture than for conventional manufacture of ceramic restorations. A second, of 13 studies, found the difference significant only for esthetic complications, and concluded that clinical outcomes were similar. A randomized pilot of 18 patients found the two rated equally by the patients themselves.

An exam is how we find out, and we will go through the options with you.
What Can Go Wrong
A crown is a repair, not an ending. The honest list:
- A crowned tooth can still decay. Secondary caries and loss of retention are the major causes of failure in the zirconia crown literature. A gap at the margin is where bacteria accumulate, which is what your check-ups are looking at.
- Crowns can come loose or fracture. Ceramics have a susceptibility to fracture and chipping, and loss of retention shows up in the clinical data too.
- The tooth can be sensitive afterwards. Dentin contains microscopic tubules; where it loses its covering, these let heat, cold and acidic or sticky foods reach the nerves.
- A prepared tooth can later need root canal treatment. A meta-analysis of 37 studies put pulp necrosis after indirect restorations at 5.02%, and a prospective study of 120 teeth found 9%, rising to 13% where the tooth was already compromised. A review of insurance claims covering 88,409 crowns found the risk of later root canal treatment low, though it was the most common untoward event. Root canal treatment is not done at this practice.
You will be given written instructions for your own case. Follow those, and call the office during opening hours if something is not right.
How Long a Crown Lasts
Skip the “10 to 15 years” you will read elsewhere: the systematic reviews measure five years.
A 2026 meta-analysis of tooth-supported single crowns put five-year survival at 98.5% for monolithic lithium-disilicate reinforced glass-ceramic, 97.1% for metal-ceramic and 96.8% for monolithic densely sintered zirconia. Its conclusion is the one that matters if your crown is ceramic: lithium-disilicate and zirconia-based all-ceramic crowns achieve five-year survival comparable to metal-ceramic ones. The stronger ceramics are not a trade-off against longevity.
Crowns at Our Everett Practice
Ceramic crowns here are placed by our three general dentists, Dr. Nadia Aboulhosn, Dr. Joanna Valentine and Dr. Fiona Kwok, and made in a dental laboratory from fully digital impressions. Nitrous oxide and oral sedation are available if the appointment itself is the worry.
What a crown costs depends on the tooth and what your plan covers. We are in network with Delta Dental/WDS, Regence, Premera, Aetna and Cigna, and out of network with MetLife, United and Concordia. Call the office and we’ll go through yours before you commit to anything.
Common Questions About Dental Crowns
How many visits does a crown take?
More than one. Because the crown is made in a laboratory from your impression, the ADA says indirect restorations usually require several visits, and a dental school says a few. You will be given your dates at the first appointment.
Can a crown go on a front tooth?
Yes, and the shade matters more there, because a mismatch shows. A 2015 systematic review also found the weaker, more translucent ceramics survived less well at the back of the mouth, so they belong at the front.
Does a crown need any special cleaning?
Not a special routine. The ADA recommends flossing once a day, and notes that people with dental work may find other cleaning tools easier.
Do you do same-day crowns?
No. Crowns here are made in a dental laboratory from a digital impression, so fitting one takes more than a single visit.
