– exactly how a dentist provides a crown for a patient-  1) tooth preparation,  2) taking the impression,  3) The temporary crown  and  4) Cementing the permanent crown. | exactly how long walk the procedure of obtaining a crown take?

This page outlines the measures of the this crowning process, and deal with common questions and also concerns the patients typically have around it.

You are watching: How long does it take to put a crown on

We’ll begin off with covering this point …

How long does it take to put a long-term crown top top a tooth?

The crowning process usually takes 2 visits.

It generally takes a dentist two separate appointments come make and also place a new dental crown for a patient.

The an initial appointment involves: 1) preparing (shaping) the tooth, 2) acquisition its impression and also 3) placing a temporary crown. The time needed to do these steps frequently ranges indigenous 50 come 90 minutes.

(A inspection of 1777 dentists performed by Minye figured out that the median amount of chair time scheduled for this portion of the procedure to be 76 minutes, add to or minus 21 minutes.) 

During the time duration between the two appointments, a dentist laboratory will fabricate the crown. Two weeks or so room usually allotted because that this process.When the patient returns because that their second visit, the dentist will certainly evaluate the to the right of the crown and then cement it into place. This step have the right to usually be perfect in about 20 to 30 minutes or so.


That method all of her appointments together, spaced around two mainly apart, will certainly take somewhere on the bespeak of 1.5 come 2 hours of yes, really time sitting in your dentist’s chair.

Single-visit crowns.

As a sport of the crowning process, part dentists have actually the needed equipment so they have the right to make and also place dental crowns in a solitary visit, in simply an hour or two of appointment time. How’s this possible?

The actions of the crowning process …

Since many patients’ procedures are reserved as two separate appointments, we’ve separated our coverage of the procedure up in the very same way.

A) The early (tooth preparation) appointment.

Step 1: Numbing her tooth up.

Is the painful to have actually a crown produced your tooth?

No, enduring pain during your crowning procedure must not be an issue.

Before the process is begun, her dentist will have to anesthetize (numb up) both her tooth and the gum tissue that surrounding it.In the situation that her tooth has had root canal treatment, that won’t need numbing. However, her dentist might feel the anesthetizing the gum organization immediately around it is tho necessary.

(If you’re curious, right here are details about receiving dentist injections, like why some hurt more than others. The reasons.)Step 2: prepare (shaping) the tooth.

a) A specific amount of this structure have to be trimmed away.

All crowns need to have a details minimal thickness. This ensures that they have enough bulk to have adequate strength. And in the case of porcelain crowns, enough ceramic thickness to have the ability to create a life-like appearance.

Preparation the a tooth because that a dental crown.


Quantifying just how much palliation takes place.

We ran throughout an exciting pair the research documents (Edelhoff) that figured out the percentage of a tooth’s crown portion (the component of a tooth the lies over the gum line) the is commonly trimmed away throughout the crowning process.

For former teeth, this number ranged in between 63% and also 73%.For back teeth, the variety extended native 67% to 75%.

(The calculations were for all-ceramic and also metal-ceramic crowns. All-metal crowns, like gold ones put on earlier teeth, would call for slightly less tooth reduction.)

Additional this reduction.
As the trimming process takes ar your dentist should remove any type of decay that’s present. They must likewise remove all pieces of tooth structure or filling product that are loose or unsound. Because of these requirements, some sections of your tooth might be trimmed substantially. (That’s not necessarily a concern. The crown will just be thicker in those areas.)

▲ Section referrals – Edelhoff

b) The prepared tooth must have a specific shape.

Besides reduce the all at once size of her tooth, your dentist must additionally trim the so it has a generally tapered shape. That’s forced so the perfect crown (a tough object that can’t flex) is maybe to slip onto the tooth and into place. (A dentist would certainly state this together saying the crown must have a “path the insertion.”)

The shape of the all set tooth help to for sure the crown’s retention and stability.

No crown is organized in place by dental cement alone (no cement is that strong). Instead, the form of the this on i m sorry it sit plays a significant role in offering for that stability and retention. Here’s how:

The taller the nub of tooth that extends up right into the internal of the crown, the much better it will certainly be at resisting tipping forces.Crown preparations that maximize the size of the nub (both in height and diameter) maximize the quantity of surface ar area for the tooth/cement interface.The an ext parallel the opposite political parties of the nub are, the better the crown will remain in place.

The ideal amount that taper different according to the type of tooth yet generally ranges from 10 to 20 levels (with each opposing side of the this contributing about 1/2 of that total).▲ Section references – Shillingburg

Due to the prominence of these considerations, there deserve to be times once so much tooth framework has broken off or decayed away the the dentist must an initial “build up” the tooth v filling material Placing a dentist “core.” that restores that closer come its original dimensions prior to they shape it for its crown.

Step 3: taking an impression that the ready tooth.

Once your dentist has completed shaping her tooth, castle will need to make a copy of that by method of acquisition a dental impression. There are two different processes by which this step can be performed.

a) standard dental impressions –How the impression is taken.

Most dentists will certainly take an impression of your tooth making use of a dough or putty-like compound that’s regularly just referred to as “impression material.”


1) The ready tooth is washed and dried.2) small diameter yarn (“retraction” cord) is tucked approximately the tooth, in the room between it and its surrounding gum tissue.

(The idea is that the cord pushes the gum tissue earlier away indigenous the tooth. Climate later, ~ it’s to be removed, the gums will certainly stay earlier long sufficient for the impression product to seep about the tooth, thus enabling it to record a copy of the whole tooth preparation.)

3) A tiny amount that light-bodied (runny) impression material is squirted approximately the tooth. (Its consistency is comparable to mustard.)

(A dentist will periodically use your air syringe to blow/spread that over and around the tooth.) 


4) A tray that’s been filled through heavy-body (thick, stiff) impression paste or putty is climate squished end the tooth and also its neighboring teeth, and permitted to sit for some minutes.

(As the tray is seated, the comparative stiffness the the putty the it’s been filled with forces the runny impression dough into every one of the nooks and crannies the the tooth and its neighboring gum tissue.)

5) together the different impression materials set, lock fuse together right into a solitary unit.6) when removed native the mouth, the impression (see picture) consists of a copy of the prepared tooth, it’s bordering gum tissue, and also the this on the jaw.


An impression the the opposing this (the teeth that the crown will certainly chew against) will6 should be bring away too. As well as some sort of “bite” impression, so to record the way the patient closes their teeth together.

How the impression is used.The perfect impression is sent out to a dentist laboratory. And also there the is filled v plaster to develop a cast.

It’s this copy of your mouth that’s then supplied to fabricate her crown.

Since the cast is a an accurate representation of your tooth and also its neighboring teeth, if the crown is made to fit ~ above it, it need to fit correctly on her tooth too.

(In most cases, a small bit of mediate is still necessary.)

Depending ~ above the specific arrangements your dentist has actually made through the dentist laboratory, the quantity of turn-around time required to fabricate a crown is generally on the order of 2 weeks, possibly less (especially if arrangements have actually been do in advance).


b) Optical dentist impressions.

As an alternating method, some dentists have tools for acquisition optical impressions. This process involves the usage of a little hand-held, wand-like digital camera (intraoral scanner).

Obviously, through this technique no impression paste is used. Retraction cord, however, might still be forced so the full extent of the tooth’s preparation is exposed and also visible to the scanner.

With part techniques, the this is dusted. The powder that’s used adjusts the reflective properties of the tooth and gums, thus aiding the digital camera in capturing all of the details needed.

How the impression is used.

A digital impression is analyzed by CAD/CAM devices that then, under the monitor of the dentist or a laboratory technician, designs and also ultimately fabricates the patient’s restoration.

For this process:

The impression can be forwarded to a dental laboratory electronically. The lab will certainly then design and fabricate the patient’s crown and ship it ago to the dentist’s office.Some dentists have actually milling devices that deserve to design and also fabricate the patient’s repair right in their very own office. Dental crowns “in one hour.”


Step 4: place a short-lived crown.

In those instances where your dental crown will be fabricated at a dental laboratory, girlfriend will need to wait the two weeks or so while it is being made. Throughout this time period, you’ll wear a “temporary” crown.

Temporaries both safeguard (cover over) her tooth and also keep that from changing position.

(Ideally, a short-lived crown will have the same shape and provide the same duty as your future permanent crown. V the solitary difference in between the two being that it’s made utilizing less durable materials.) 

Temporaries are usually made out of plastic, or maybe metal. They may be preformed shells (metal or plastic) Details. That are then customized to fit your tooth. Or do from scrape by your dentist (plastic only).

(Only a temporary that’s tradition made the end of plastic has actually the potential to important replicate the contours and also dimensions of your future irreversible crown. For this reason if your dentist has gone come the initiative of crafting one for you, they must be commended.)

A short-lived crown is cemented using “temporary” cement, so it can be removed easily and also predictably at your next appointment.
(FYI: A momentary crown is just that. And as such, certain considerations Temporary crown precautions. Should be maintained in mind so problems are avoided.

Step 5: choosing the the shade for your crown.

If your brand-new crown will have a porcelain surface, your dentist will should judge what shade of ceramic most very closely matches your tooth’s bordering teeth.


In part cases, your dentist will usage a collection of small, tooth-shaped piece of dentist porcelain, each one having a different color. Jointly these samples are referred to as a “shade guide.”

Samples will be selected native the guide and held in the room that your brand-new crown will occupy, till one is identified to be the ideal color match.

As an alternative, her dentist may have actually an electronic maker that will immediately determine the tooth’s shade for them.


Issues.While we’ve put this action low in our outline, identify the shade for your new crown really should be among the very first things the takes place throughout your appointment. (Like while waiting for her tooth to acquire numb.)

That’s because while her mouth is open during your procedure, her tooth and neighboring this will often tend to dehydrate (dry out). And as lock do, they will end up being lighter/brighter in color, therefore making specific shade corresponding impossible. Research studies have presented (Burki) the the shade of teeth deserve to be influenced by dehydration in much less than 30 minutes.

The lighting problems in which the tooth’s shade is taken is critical factor (Park). Especially for prior teeth, an evaluation in organic light, or fabricated lighting that’s been spectrum-corrected come mimic daylight, along with other feasible lighting environments in i m sorry the tooth will certainly be viewed should all ideally be considered.


Your dentist might value additional input (from you, your assistant, etc…) about which shade shows up to complement most closely. (A inspection by Minye uncovered that 59% the dentists seek this additional input for instances involving front teeth.)Additionally, dentists sometimes use photographs to help to connect their shade choice with the dental laboratory that will make the crown. (Minye uncovered that this wake up in 50% of situations where the esthetics that the situation are specifically demanding.)

Delayed therapy / COVID-19 considerations.

Some civilization may discover themselves in a instance where because of unexpected factors, prefer the 2020 Coronavirus pandemic, the placement of their permanent crown have to be postponed.

For the most part, friend don’t have to be above concerned about complications cropping up as result of your treatment’s delay. But because your crown to be intended to simply be a short-lived one, it constantly makes feeling to generally favor it, simply to play it safe.

(Related content: short-term crown precautions. Do’s and don’ts.)

How long deserve to a momentary crown last?

While not as solid as a long-term one, the products used to do your short-term crown deserve to probably be intended to resist the wear and also tear of countless months of service. (Even 12 month or more.) examine with your dentist.

It is true that the cement supplied to certain a momentary isn’t as solid as what’s offered with long-term ones, so the opportunity of it coming off is at the very least somewhat the a concern. Girlfriend don’t need to expect the it will. However this possibility is reason sufficient to monitor the level of force that you disclose it to.

If the does come off, you should consider it a far-reaching event and you need to make call with your dentist. As an example, if the lose of the temporary allows your tooth to shift, even minutely, the impression that’s to be taken will certainly no longer be accurate and also the irreversible crown made making use of it quite possibly can’t be readjusted to fit.

As further information, this web page covers the case where you have a crown come off. What to do. Or if her has and also you have swallowed it, this one offers tips ~ above retrieving it. What come do.

Possible results of permanent wear.

The fit and also contours of a temporary crown typically aren’t as right as a permanent one’s. And if not, gift able to remove dental plaque from roughly the tooth might be difficult.

Persistent plaque accumulation can cause gum recession, gum condition and/or this decay. Each of these components can damage the result of your current (delayed) treatment, or also the outlook for your tooth, therefore be together diligent with your oral home care as you can.

B) The crown placement appointment.

Once the fabrication of your dental crown has actually been completed, her dentist have the right to proceed v the process of cementing it into place.

Step 1: removing the short-lived crown.

For this step, your dentist will:

Anesthetize (numb up) your tooth. (This action isn’t constantly needed. It’s regularly quite painless for a patient to have a crown fitted and also cemented.)They’ll then eliminate your short-term crown and also clean off any type of remnants of short-term cement that stay on her tooth.


Step 2: examining the fit and also appearance the the crown.

Before your dentist deserve to cement your brand-new dental crown right into place, castle will an initial need come make certain it fits well and looks right. Together a component of this evaluation:

Checking the fit. – her dentist will seat the crown on her tooth and also inspect the means that it fits. (This review may incorporate using dentist floss, feeling roughly the crown through a dental tool, and asking you to bite under gently on some carbon paper).

They’ll then remove the crown and adjust it together needed. (Usually via trimming or buffing it through their dentist drill.)

They might need to repeat this process several times prior to they’re satisfied with the restoration’s fit, both ~ above the tooth and also the means it touches its neighboring and also opposing teeth.

Checking the appearance. – Additionally, and also especially in those situations where the dentist crown will hold a prominent position in your smile, her dentist will most likely hand girlfriend a mirror and ask you to advice the crown’s overall shape and also color.

Don’t it is in shy through your comments and also questions. After ~ a crown has actually been cemented, some changes (like color, and also even some species of shape modifications) can not be made. We’ll repeat this point. Do not let your dentist permanently cement her crown unless you’re satisfied through its outcome.▲ Section references – Wilson


They’ll very first place dentist cement inside her crown and also then seat it over your tooth.After a couple of moments (at a suggest where the cement has actually just started to set), her dentist will use a dentist tool and scrape away any kind of excess that has actually extruded from underneath the edge of the crown.

(There have to be some excess. The dentist will constantly place slightly an ext cement within the crown than is needed, so over there is no possibility for voids.)

After removing all excess cement, your dentist will dual check your crown’s “bite” so come ensure that it’s correct. The location of your brand-new crown is currently complete.

Step 4: Precautions for your brand-new dental crown.

At this point, your dentist may provide you some instructions. For example, with some types of cement it’s finest to take it straightforward with the crown for the very first day (eat nothing exceptionally tough or sticky), for this reason to offer the cement an adequate time duration over which come cure.

Especially in the situation where you have actually been numbed up, be mindful until typical sensation has actually returned. You can easily bite her lip or cheek through accident, possibly severely.

Once your numbness has actually worn off, and also for the next day or so, gently check the “bite” of her crown so to make certain that it feels right with all varieties of closing movements. If that doesn’t, let your dentist recognize so they can correct the difficulty (a simple matter of buffing down the surface ar of the crown). No doing so have the right to lead to (possibly serious and irreversible) complications. What deserve to go wrong.

One last thing to think about.

If your tooth demands to be capped, sitting v the crowning procedure yes, really isn’t all that bad.
