Your dentist looked at your tooth and named a fix. A Crowns, Bridges And Fillings. You nodded, then wondered which one you really need.
The three words often get used together, but they do different jobs. One patches a small hole in a tooth. Another covers a whole tooth. The third fills a gap where teeth are missing.
This guide settles which fixes what. You will see what each one is, when a dentist uses it, how long it lasts, and how the choice gets made for your case. Crowns and bridges raise one more worry worth naming: whether a single office can handle the work, or whether you get sent elsewhere. That is answered here too.
Here is the short version first.

Crown, bridge, or filling: which one fixes what
A filling repairs a small area of decay. A crown covers and protects a badly damaged or cracked tooth. A bridge replaces one or more missing teeth, anchored to the teeth on each side.
That is the whole answer in three lines. A filling suits minor damage when the tooth is still intact (GoodRx). A crown suits a tooth that is badly damaged, cracked, worn, or has had a root canal (GoodRx; Valley View Dental). A bridge suits a gap left by missing teeth (Colgate; High Desert Dental).
What each one is made of, and how the three compare, comes next.
What is the difference between a filling, a crown, and a bridge
A filling is a restorative material packed into a cleaned cavity, and it rebuilds a tooth after minor decay. The usual material is composite resin, a tooth-colored blend that sits inside the tooth (GoodRx).
A crown is a cap that covers the whole visible tooth, and it restores a tooth too damaged to hold a filling. Common types of crown material include porcelain and ceramic (GoodRx; Valley View Dental).
A bridge is one or more false teeth held by crowns on the natural teeth beside the gap, and it closes the space left by missing teeth (High Desert Dental; Colgate).
The meaning of each word tracks the job it does: a filling patches, a crown caps, a bridge spans.
One more word you may hear is temporary. On a conventional crown, a temporary is a short-term cover worn between the two visits. Valley View Dental makes same-day CEREC crowns, so the crown is designed, milled, and fitted in one visit and no temporary is needed (vvdental.com).
Here is the side-by-side view.
| Option | What it fixes | Material | Visits | Relative cost | How long it lasts |
|---|---|---|---|---|---|
| Filling | A small area of decay, tooth still intact | Composite resin | Usually 1 | Lowest of the three | filling lifespan in years, needs a dated clinical citation |
| Crown | A badly damaged, cracked, or post-root-canal tooth | Porcelain or ceramic (CEREC same-day) | 1 with CEREC, otherwise 2 | Middle of the three | crown lifespan in years, needs a dated clinical citation |
| Bridge | One or more missing teeth | A false tooth (pontic) plus anchor crowns | Usually 2 or more | Highest of the three | At least 5 to 7 years, often over 10 (Colgate) |
Relative cost is a ranking, not a price. You get an exact figure as a custom quote at a free consult.
The first choice most people face is the one between a filling and a crown.
When do you need a filling, and when do you need a crown
A filling works when the decay is small and most of the tooth is still solid. A crown is needed when too much tooth is lost, or the tooth is cracked, worn, or has had a root canal.
The deciding factor is how much healthy tooth structure is left. A filling sits inside the tooth, so the tooth itself still carries the bite. Enough sound tooth structure has to remain around it (GoodRx).
A crown works from the outside in. It wraps the tooth and takes pressure off the weak parts. That is why a dentist reaches for a crown after a large or failing filling, severe decay, a cracked tooth, heavy wear, or a root canal (GoodRx; Valley View Dental).
A cracked tooth is the case people misjudge most. A crack can look small on the surface and still run deep into the tooth.
Both of those fixes assume the tooth is still there. When it is gone, the answer changes.
When do you need a bridge, and how is it different from an implant
A bridge spans a gap using the teeth on either side as anchors, and it replaces one or more missing teeth without surgery. The false tooth in the middle is called a pontic. It is held by crowns cemented onto those two neighboring teeth (High Desert Dental; Colgate).
So a bridge needs usable teeth beside the gap. Those teeth get shaped to take the anchor crowns. That is the trade-off you accept in exchange for skipping surgery.
A dental implant answers the same problem a different way. An implant is a titanium post placed in the jaw, and it replaces the tooth root itself. The neighboring teeth are left alone.
Which one suits you depends on your bone, the teeth beside the gap, and what you want. That comparison runs deeper than this guide, and a dentist can walk you through it in person. Valley View Dental places both, with an in-house oral surgeon on the team.
Whichever fix you land on, the next question is how long it holds up.
How long do fillings, crowns, and bridges last
A dental bridge lasts at least 5 to 7 years, and often more than 10 years with good hygiene and regular visits (Colgate, citing Cleveland Clinic and the University of Rochester Medical Center).
Crowns and fillings need an honest note. Many pages quote a round number of years with no source behind it. This guide will not state a figure until it is tied to a dated clinical citation.
What is documented is that a filling does not last forever and can need replacing over time (GoodRx). All three are repairs, not finished teeth. Each one gets checked at your regular visits and replaced when it wears.
Lifespan is one worry. What the appointment feels like is the other.
Do these procedures hurt, and what is recovery like
A filling and a crown may leave the tooth a little sensitive for a few days. That sensitivity usually settles within 1 to 2 weeks (GoodRx).
Recovery from either one is short by that measure. The sensitivity fades as the tooth settles.
A bridge is placed over more than one visit, because the anchor teeth are prepared before the bridge is fitted.
The care itself is gentle and judgment-free at Valley View Dental. No one comments on how long it has been since your last visit. If sensitivity is still there well past that 1 to 2 week window, that is worth a call.
Comfort aside, the real question is which fix belongs on your tooth.
How does a dentist decide which one is right for your case
The right choice depends on how much healthy tooth is left and whether any teeth are missing. Enough sound tooth points to a filling, too little points to a crown, and a missing tooth points to a bridge or an implant.
That reads simple until your case is not simple. A cracked tooth next to an old root canal and a gap is where people get sent to three different offices, and where the quotes stop matching each other.
At Valley View Dental the case stays in one place. The team includes an in-house prosthodontist, Dr. Tarik Patel, an endodontist, Dr. Fuwad Al-Sabek, and a board-certified oral surgeon, Dr. Anthony Lotesto. Complex cases are handled in-house by these specialists rather than referred out.
Timing is part of the answer too. A same-day CEREC crown is designed, milled, and fitted in a single visit, with no temporary crown and no second appointment (vvdental.com). It is a long-lasting restoration, built to last, and it goes in on the same day the tooth is prepared.
Valley View Dental has served Romeoville, Naperville, and Montgomery for more than 20 years.
Here are the questions people still ask.
Frequently Asked Questions
What is the difference between a crown, a bridge, and a filling?
A filling repairs a small cavity, a crown caps a badly damaged tooth, and a bridge replaces a missing tooth. The difference comes down to how much tooth is left. A filling goes inside the tooth, a crown goes over it, and a bridge stands in for a tooth that is gone (GoodRx; Colgate).
When do you need a crown instead of a filling?
You need a crown instead of a filling when too much tooth is lost, or the tooth is cracked, worn, or has had a root canal. A filling still needs solid tooth around it to work. Once that is gone, a crown carries the load instead (GoodRx; Valley View Dental).
Does getting a crown hurt more than a filling?
Both a crown and a filling may leave the tooth sensitive for a few days, and that usually settles within 1 to 2 weeks (GoodRx). The two feel broadly similar afterwards. Care at Valley View Dental is gentle and judgment-free.
How long do crowns, bridges, and fillings last?
A bridge lasts at least 5 to 7 years, and often more than 10 with good care (Colgate). Crown and filling figures are not stated here without a dated clinical source.
Is a bridge or an implant better for a missing tooth?
A bridge uses the neighboring teeth as anchors, while an implant replaces the root without touching them. Which one fits depends on your bone and on the teeth beside the gap. A dentist can tell you which applies to your case at a free consult.
Crowns, bridges and fillings – which one you need
Now you can tell the three apart. A filling patches a small area of decay when the tooth is still mostly solid. A crown caps a tooth that is too damaged, cracked, worn, or root-canal treated to hold a filling. A bridge spans a gap where teeth are missing, anchored to the teeth on each side. The deciding factor is always how much healthy tooth is left, and whether any teeth are gone. Enough sound tooth points to a filling, too little points to a crown, and a missing tooth points to a bridge or an implant.
The hard cases are the mixed ones, a cracked tooth beside an old root canal and a gap, which is exactly where people get sent from office to office and the quotes stop matching. That is where we come in. At Valley View Dental, a prosthodontist, endodontist, and oral surgeon work under one roof, so complex cases stay in one place with no referral, and same-day CEREC crowns go in without a second visit. Call (630) 509-7933 or book a free consult to find out which fix belongs on your tooth, with your cost in writing before you decide.
