In brief
If you want a fixed (non-removable) replacement for a missing tooth, the choice is usually a dental bridge or an implant. A bridge uses crowns on the neighbouring teeth to hold an artificial tooth; it is non-surgical and often finished within weeks. An implant places an artificial root in the bone, takes months, and leaves the neighbouring teeth untouched. A bridge often suits teeth that already need crowns; an implant often suits healthy neighbours and good bone.
Key takeaways
- Both bridges and implants are fixed, non-removable replacements.
- A bridge is non-surgical and typically finished in a few weeks.
- A bridge makes particular sense when the anchor teeth already need crowns.
- An implant avoids reshaping neighbouring teeth and helps preserve bone.
If you have decided you want a missing tooth replaced with something fixed, rather than a removable partial denture, your two main choices are a dental bridge and a dental implant. A bridge is often the better fit when the teeth beside the gap already need crowns, when surgery is not a good option, or when you want the space filled within weeks. An implant is often preferred when the neighbouring teeth are healthy and there is enough bone to support it.
This article looks at the decision from the bridge side. It is written for people who are leaning toward a fixed option and want to know whether a bridge makes sense for them, what getting and living with one involves, and when an implant may be the stronger choice. For a full side-by-side comparison of the two treatments, see our companion guide, dental implants vs dental bridges.
Why choose a fixed replacement instead of a removable one?
A fixed replacement stays in your mouth all the time. You do not take it out to clean it or to sleep, and there is no clasp or plate to get used to. For many people, that is the main reason they rule out a partial denture before they even start comparing bridges and implants.
Patients often say a fixed tooth feels more like their own, stays put when they bite into something firm, and has no clasps or plate to show or manage.
Removable partial dentures still have a real place. They often cost less at the start, they can replace several teeth in different parts of the mouth at once, and they involve little or no change to the remaining teeth. If you are weighing removable options too, complete dentures vs partial dentures and our dentures page explain how they work. The rest of this article assumes a fixed option is your preference.
What decides whether a bridge or an implant is the better fixed option?
Once you have ruled out a removable denture, the decision usually turns on a handful of practical questions. Your dentist will look at each one during an examination, but it helps to think about them before your appointment.
What condition are the teeth beside the gap in?
This is often the deciding question. A bridge is held by crowns placed on the neighbouring teeth, so those teeth have to be reshaped. If they already have large fillings, cracks or past root canal treatment, crowning them may protect them anyway, and a bridge puts that work to double use. If they are healthy and untouched, reshaping them removes sound enamel for good, which is the main argument for an implant.
How much bone is there where the tooth is missing?
An implant needs enough healthy bone to hold the post. If a tooth has been missing for some time, the bone in that area may have thinned, and grafting may be needed before an implant can be placed. A bridge does not rely on the bone at the gap in the same way. You can read more about this in dental implants after bone loss.
How do you feel about surgery and healing time?
Implant placement is a minor surgical procedure, followed by a healing period of a few months or more. A traditional bridge involves no surgery. Some patients simply prefer to avoid a surgical step, and some have health conditions or take medications that make surgery and healing less predictable. Your dentist will ask about your medical history to help weigh this.
How soon do you want the gap filled?
A bridge is often completed in a few weeks. Implant treatment usually spans several months from placement to the final crown, and longer if an extraction or grafting comes first. If you have an event coming up, or a front tooth gap you want closed quickly, timeline can carry real weight.
What fits your budget now and over time?
A bridge often costs less at the start. Over the long term, the comparison depends on how long each option lasts in your mouth and what maintenance or repairs come up along the way. Your dentist can explain the estimated fees for each option once your needs are clear.
Which fixed option often fits which situation?
The table below is a general starting point, not a diagnosis. Your own teeth, gums and health may point in a different direction.
| Your situation | Fixed option that often fits | Why |
|---|---|---|
| Teeth beside the gap already have large fillings or need crowns | Bridge | The crowns that hold the bridge also protect those teeth |
| Teeth beside the gap are healthy and unfilled | Implant | Avoids removing healthy enamel |
| Bone at the gap has thinned and you prefer to avoid grafting | Bridge | Does not depend on bone volume at the gap in the same way |
| You want the gap filled within a few weeks | Bridge | No surgical healing period |
| You would like to avoid surgery | Bridge | A traditional bridge involves no surgical step |
| One tooth missing with a long, healthy future ahead for the neighbours | Implant | Stands on its own, so neighbouring teeth are not tied to it |
| Several teeth missing in a row | Case by case | Longer spans may need implant support or a partial denture |
Choosing a bridge now does not always rule out an implant later, if the bone and gums at the site still allow it when the bridge eventually needs replacing.
If you would like to see every choice laid out, including removable options and leaving the space, options for replacing one missing tooth covers them all.
What makes a tooth a good anchor for a bridge?
A bridge is only as strong as the teeth holding it. Before recommending one, your dentist will look closely at the anchor teeth (also called abutment teeth) to confirm they can carry the extra load for years to come.
Things your dentist checks include:
- Root length and shape. Longer, well-shaped roots give better support. X-rays show what cannot be seen in the mouth.
- Gum and bone support. Healthy gums and bone around the anchor teeth are essential. Active gum disease is usually treated first.
- Existing restorations. Large fillings or old crowns are not a problem in themselves, but the tooth underneath needs to be sound.
- Root canal history. A tooth that has had root canal treatment can often serve as an anchor, and it frequently needs a crown anyway. Our article on getting a crown after root canal treatment explains why.
- Your bite. Heavy grinding or clenching places more stress on a bridge and its anchors, and your dentist may suggest ways to protect it.
- The length of the gap. Bridges commonly replace one or two teeth. Longer spans place much more force on the anchors and are assessed carefully.
If an anchor tooth is weak, a bridge may not be the best choice, even if it seems simpler at first. In that case your dentist may suggest an implant, a different bridge design or a partial denture.
When may an implant be the better fixed choice?
The main trade-off with a bridge is the work done on the anchor teeth. Healthy enamel is removed to fit the crowns, and those teeth then support the replacement tooth as well as themselves. If the neighbouring teeth are in excellent condition, many dentists prefer not to reshape them, and a dental implant leaves them untouched.
Other reasons an implant may come out ahead:
- Bone support at the gap. An implant sits in the bone and may help limit the shrinkage that tends to follow tooth loss. The ridge under a bridge’s artificial tooth can slowly change shape over the years.
- Independence from other teeth. If one anchor of a bridge develops decay or a crack, the whole bridge is affected. An implant stands alone.
- Easier flossing. You can floss around an implant crown much as you would a natural tooth.
An implant does need enough bone, healthy gums and a healing period, and a consultation is the first step. Our team will explain which stages can be completed at York Street Dental Centre and whether coordination or referral to another dental provider is appropriate.
What does getting a bridge involve, visit by visit?
For most people, getting a bridge feels much like getting a couple of crowns. The details vary, but a traditional bridge usually follows these steps.
First visit: assessment and planning
Your dentist examines the gap, the anchor teeth and your gums, and takes X-rays. You will talk about your options, including an implant or a partial denture, along with the estimated fees for each. If you choose a bridge, you can ask the office to send a predetermination to your insurer.
Preparation appointment
The anchor teeth are numbed with local anaesthetic and reshaped so the crowns can fit over them. An impression or scan is taken and sent to a dental laboratory, and the shade is matched to your other teeth. A temporary bridge is placed to protect the prepared teeth and fill the space while you wait.
Fitting appointment
When the finished bridge arrives, your dentist checks its fit, bite and colour. Small adjustments are made if needed, and then the bridge is cemented in place. You will be shown how to clean under it before you leave.
How do you clean under a dental bridge?
Because a bridge is one connected unit, regular floss cannot pass between the artificial tooth and its neighbours. The area under the artificial tooth, and the gumline around the anchor teeth, need daily attention. This is where plaque tends to collect, and it is where decay and gum inflammation usually begin.
A simple daily routine
- Brush twice a day with a soft toothbrush and fluoride toothpaste, angling the bristles toward the gumline around the anchor crowns.
- Clean under the artificial tooth once a day. Use a floss threader, a floss with a stiffened end, or a small interdental brush to reach under the pontic and along the sides of the anchor teeth.
- Consider a water flosser if you find threaders difficult. It can help rinse debris from under the bridge, though it works best alongside, not instead of, mechanical cleaning.
- Keep your regular visits. Professional cleanings reach areas under and around the bridge that are hard to clean at home.
If you notice bleeding, a bad taste or food trapping under the bridge that does not clear with cleaning, mention it at your next visit or call sooner.
How long does a dental bridge last?
Many bridges serve well for many years, and some last much longer. No restoration can be guaranteed to last a set length of time. How long a bridge lasts depends largely on the health of the anchor teeth and gums underneath it.
Things that tend to shorten a bridge’s life include:
- decay starting at the edge of an anchor crown,
- gum disease weakening the support of the anchor teeth,
- heavy grinding or clenching, and
- missed checkups, which allow small problems to grow.
The same factors that affect crowns apply here, and our guide on how long dental crowns last goes into more detail.
What happens if a bridge anchor tooth has a problem later?
If an anchor tooth develops decay, cracks or infection, the whole bridge is affected, because it is one piece. Depending on the problem, your dentist may be able to treat the tooth and keep the bridge, or the bridge may need to be removed and remade.
In some cases, when a bridge reaches the end of its life, it can be replaced with an implant, or with a combination of an implant and a new crown on the neighbouring tooth. Whether that is possible depends on the bone and gum at the site at that time. This is one reason regular checkups matter: problems caught early usually leave you with more options.
What affects the cost of a bridge or an implant?
We do not quote fees without an examination, because the total depends on what your mouth needs. For a bridge, cost factors include:
- how many teeth the bridge replaces and how many anchor crowns it uses,
- the material chosen, and
- any treatment needed first, such as fillings, root canal treatment or gum care for the anchor teeth.
For an implant, the main factors are any extraction or bone grafting, the imaging and planning involved, and the type of final crown.
Insurance, CDCP and tax credits
Private dental plans differ in how they cover bridges and implants. Some cover part of either, some cover one but not the other, and some have waiting periods or yearly maximums. Asking the office to send a predetermination is the clearest way to know your share before you start. We direct bill many plans, which can simplify the paperwork.
Dental implants are not listed among the services covered by the Canadian Dental Care Plan (CDCP). If you have CDCP coverage and are considering a bridge, check the current coverage list or ask our team, since coverage details can change. The Canada Revenue Agency lists dental implants as an eligible medical expense for the medical expense tax credit. For how other dental treatment is treated on your return, a tax professional can advise you.
What should you ask at your consultation?
Bringing a few questions can make your appointment more useful:
- Are the teeth beside the gap strong enough to anchor a bridge?
- Would those teeth benefit from crowns anyway?
- Do I have enough bone for an implant, or would I need grafting?
- How long would each option take from start to finish?
- What are the estimated fees for each option, and what might my insurance cover?
- How would I clean each option at home?
- If I choose a bridge now, could I still have an implant later?
A good consultation should leave you understanding the trade-offs, not just the recommendation.

Frequently asked questions
How many missing teeth can a bridge replace?
Commonly one or two adjacent teeth. Longer spans place greater stress on the anchor teeth and are assessed case by case; sometimes implants or a partial denture are more appropriate for larger gaps.
Does getting a bridge damage my other teeth?
Preparing anchor teeth removes enamel permanently, which is a genuine trade-off — minor if those teeth needed crowns anyway, significant if they were untouched. This is central to the bridge-versus-implant decision.
Can a bridge be replaced by an implant later?
Often, yes, subject to bone condition at the site. If a bridge reaches the end of its life, an assessment can determine whether an implant is feasible at that point.
Is a bridge noticeable?
Modern materials allow bridges to blend closely with natural teeth in shape and shade. Front-tooth bridges are routinely made to be visually seamless.
Does getting a dental bridge hurt?
Preparing the anchor teeth is done with local anaesthetic, so most people feel pressure and vibration rather than pain. Some temporary sensitivity to cold or mild gum tenderness is common for a few days afterward. Because there is no surgery or bone healing, recovery is usually quicker than with an implant.
Can I get a bridge if I have gum disease?
Gum disease usually needs to be treated and brought under control first. A bridge depends on the anchor teeth having healthy gum and bone support, and untreated gum disease can weaken that support over time. Your dentist will check your gums and may recommend cleanings or other care before planning a bridge.
