Quick answers
- Save the tooth or replace it?
- Depends on how much sound tooth remains above the gum, not on how much it hurts.
- Is an implant better than a crown?
- No. A natural root you can keep is generally worth keeping. An implant is what you do when you cannot.
- Can a crown fix a cracked tooth?
- Sometimes. A crack confined to the crown portion is often restorable. One running into the root is not.
- Do crowns and implants ever work together?
- Yes. An implant crown is a crown attached to an implant, replacing a whole tooth.
- Which lasts longer?
- An implant cannot decay, but it can lose bone support. A crowned tooth can decay but keeps its ligament.
- Which costs more?
- An implant, usually by a wide margin, since it involves surgery plus an abutment plus a crown.
Can this tooth be saved with a crown, or does it need an implant?
The deciding factor is how much healthy tooth structure is left above the gum line, and whether the root is intact. A crown does not add strength on its own. It is a cover that redistributes force, and it needs a solid band of sound tooth to grip. Where that band is missing, a crown placed anyway tends to fail within a few years, taking the remaining tooth with it.
What we assess when deciding between restoring and replacing
| Finding |
Points toward a crown |
Points toward extraction and an implant |
| Remaining tooth structure |
A continuous band of sound tooth above the gum |
Decay or fracture extending below the gum on several sides |
| Crack pattern |
Confined to the crown portion of the tooth |
Extending vertically into the root |
| Bone support |
Stable, tooth is firm |
Significant loss, tooth is mobile |
| Root condition |
Intact, treatable if infected |
Fractured, resorbed, or perforated |
| Gum health |
Healthy or treatable |
Advanced disease around that tooth |
| Position and bite load |
Force can be managed |
Heavy load on a structurally compromised tooth |
Two points patients find surprising. Pain is not a criterion — an infected tooth can be entirely restorable after root canal treatment, while a comfortable tooth with a vertical root fracture cannot be saved. And a tooth that has already been crowned once is not automatically due for extraction; what matters is what is left underneath.
Where the answer is genuinely borderline, we will say so rather than manufacture certainty. Sometimes the reasonable plan is to attempt restoration knowing that an implant remains available if it fails.
Crown vs implant: how they differ
These are not competing products. They address different situations, and the comparison only matters when a tooth is on the boundary between them.

When crowns and implants work together
An implant crown is where the two halves of crowns and implants dentistry meet. What patients call “an implant” is three components, made at different times and usually billed separately.
Components of a single implant restoration
| Part |
What it is |
When it is placed |
| Implant |
A titanium post in the jawbone, replacing the root |
Surgical appointment |
| Abutment |
The connector between implant and crown, stock or custom |
After integration |
| Crown |
The visible tooth, matched to your others |
After the abutment is fitted |
The abutment is the part most patients have never heard of and the one that most affects how the finished tooth looks where it meets the gum. A custom abutment is shaped to your tissue contour and controls where the crown margin sits.
The absence of a periodontal ligament explains several things you will notice. An implant tooth does not sense pressure the way a natural tooth does, so biting something hard is more likely to chip it. It is also why the bite on an implant crown is deliberately adjusted lighter: with no ligament to absorb force, the implant takes the load directly.
Screw-retained vs cemented implant crowns
This decision determines how easily the crown can be serviced for the rest of its life, and most patients are never told it exists.
Retention methods compared
|
Screw-retained |
Cemented |
| How it attaches |
A screw through the crown into the implant |
Cemented onto an abutment |
| Removable by the dentist |
Yes, unscrewed and replaced |
Usually has to be cut off |
| Visible access hole |
Yes, filled with tooth-colored material |
None |
| Appearance in the smile zone |
Good, limited by implant angle |
Generally better |
| Main drawback |
Screw loosening is more common |
Excess cement left below the gum |
| Often chosen for |
Back teeth, cases likely to need servicing |
Front teeth, unfavorable implant angles |
The cement concern deserves accuracy rather than alarm. Cement itself is not the problem; excess cement left beneath the gum is, because it holds bacteria where they cannot be cleaned. That risk is largely a function of how deep the crown margin sits, which is why custom abutments bringing the margin nearer the gum line are used where cementing is planned.
The comparative evidence is more balanced than the popular framing suggests. A 2023 systematic review and meta-analysis found moderate-certainty evidence that cement-retained and screw-retained restorations carry a similar risk of peri-implant mucositis and peri-implantitis, while screw loosening occurs more often with screw-retained crowns. Neither is simply better. The right choice depends on tooth position, implant angle, and how likely the crown is to need servicing.
How long does each treatment take?
A crown is measured in weeks. An implant is measured in months, because bone has to grow against it before anything can be attached.
Typical timelines
| Treatment |
Sequence |
Usual duration |
| Crown on a natural tooth |
Preparation, temporary, laboratory fabrication, delivery |
Two to three weeks |
| Same-day crown |
Preparation, in-office milling, delivery |
One appointment |
| Implant placement |
Surgery |
One appointment |
| Osseointegration |
Bone grows against the implant |
Three to six months |
| Abutment and implant crown |
Records, laboratory fabrication, delivery |
Two to three weeks after healing |
Healing time varies with bone quality, whether grafting was required, and which jaw is involved. A temporary tooth can usually be worn during healing so you are not left with a visible gap.
What crowns and implants dentistry costs
A crown is a single fee. An implant is three, and quoted implant prices frequently exclude the abutment and crown. When comparing estimates between offices, confirm what the figure covers.
What moves the total:
- Which treatment. Restoring a tooth is consistently less expensive than replacing one.
- Preparatory work. Root canal treatment, extraction, or bone grafting is priced separately.
- Abutment type. Custom costs more than stock and gives better tissue contour.
- Material. Zirconia, layered porcelain, and other options differ in cost and appearance.
- Position. Front teeth demand more of the laboratory work.
- Imaging. Three-dimensional planning is used in some implant cases.
Dental plans often treat crowns and implants under different benefit categories, sometimes with different percentages and separate annual maximums. Where an implant is planned, splitting treatment across two benefit years is occasionally worth discussing. We verify your plan and give you a written estimate covering every component rather than the first one. Patients without insurance can use our membership plan or flexible payment options. For background, see how much do dental implants cost.
Looking after crowns and implants
They fail in different ways, so they need attention to different things.
A crowned natural tooth remains vulnerable at the margin, where the crown meets tooth. That junction collects plaque and can decay, often without discomfort until the problem is advanced. Flossing at the gumline around a crown matters more than brushing its surface.
An implant crown cannot decay, which leads some patients to relax about it. The tissue around it still can become diseased. Peri-implantitis is inflammation and bone loss around an implant, driven by bacteria much as gum disease affects natural teeth, and it is the leading cause of late implant failure. It is usually painless early on, which is why it is found at examinations rather than felt.
For both:
- Clean between the teeth daily, including beside and beneath the restoration
- Keep routine professional cleanings, where instruments suited to implant surfaces are used
- Wear a night guard if you grind, since neither restoration tolerates sustained overload well
- Report bleeding, tenderness, looseness, or a change in your bite promptly
Tell any new dental office that you have an implant. The instruments and techniques used around implant surfaces differ from those used on natural teeth.
Why is my crown or implant loose?
Most problems are mechanical and fixable, provided they are reported early rather than lived with.
- A crown on a natural tooth feels loose. Often the cement has failed or decay has developed underneath. It can sometimes be recemented; where decay has undermined the tooth, more work is needed.
- An implant crown feels loose. Usually the abutment screw has loosened, frequently corrected in one short visit. Continuing to chew risks fracturing the screw, which is a considerably harder repair.
- Porcelain has chipped. Small chips can sometimes be polished or repaired. Larger ones may need the restoration remade.
- Food packs beside it. The contact with the neighboring tooth has opened. Worth correcting rather than tolerating, since it traps bacteria.
- The gum bleeds around it. Have it examined. Early inflammation is treatable; established bone loss is much harder to reverse.
- The bite feels high. Adjustment is straightforward and worth doing promptly, since an overloaded tooth or implant is at risk.
