Dental implants are artificial tooth roots, usually made of titanium, that are placed in the jawbone to support a replacement tooth, a bridge or a denture. Once the bone has bonded with the implant, a connector called an abutment is attached, and a custom crown or other restoration is fitted on top. The result is a fixed, natural-looking tooth anchored in the jaw in a similar way to a natural root.
Because an implant replaces both the root and the visible part of a tooth, it offers a form of implant-supported tooth replacement that does not rely on the neighbouring teeth for support. That is one of the main reasons people choose implants over a conventional bridge or a removable denture.
Implants are not suitable for everyone. Bone volume, gum health and general health all affect whether treatment can go ahead, and some people need preparatory care first. This guide from Barton Dental in Hamilton explains how implants work, who tends to be a good candidate, how the procedure unfolds and how long implants can last.

How Do Dental Implants Work to Replace Missing Teeth?
A dental implant works by fusing with the jawbone. This process, known as osseointegration, gives the replacement tooth a stable foundation that can handle everyday biting and chewing.
The three main parts of an implant
| Component | What It Does |
| Implant post | A small titanium post placed in the jawbone to act as the new root |
| Abutment | A connector attached to the post once healing is confirmed |
| Restoration | A custom crown, bridge or denture that forms the visible tooth or teeth |
At Barton Dental, we use a titanium post that replaces the root, an abutment that supports the crown, and a custom ceramic crown matched to the colour and shape of your surrounding teeth. The U.S. Food and Drug Administration also describes implants as medical devices surgically placed in the jaw to restore chewing ability or appearance.
What happens inside the bone
Over several months, bone grows around the surface of the implant post and locks it into place. Until this bond forms, the implant is not ready to carry a permanent tooth. The healing period is the main reason implant treatment takes longer than a bridge or a denture.
Ways implants can replace teeth
A missing tooth implant can be used in several ways, depending on how many teeth are missing:
- One missing tooth: a single implant supports a single crown.
- Several teeth in a row: implants can support a fixed bridge, so each missing tooth does not always need its own implant.
- Many or all teeth in an arch: two or more implants can hold an implant-supported denture, which is more secure than a denture that rests on the gums alone.
If you are comparing fixed and removable options, we also offer Dentures and Crowns & Bridges.
Who Is a Good Candidate for Dental Implant Treatment?
A good candidate for dental implants is usually someone with healthy gums, enough jawbone to support the implant and general health that allows a minor oral surgical procedure. The dentist confirms this through an examination and imaging.
The factors that matter most
- Bone volume and density. The implant needs enough bone around it to stay stable. Bone can shrink after a tooth is lost, especially over time.
- Gum health. Active gum disease needs to be treated before an implant is placed.
- Overall health. Some medical conditions and medications can affect healing, so your medical history is reviewed.
- Oral hygiene habits. Implants need daily cleaning and regular checkups, just like natural teeth.
The Canadian Dental Association notes that people considering implants should have healthy gums and enough bone to hold the implant, and that the decision is best made with your dentist.
Age and implants
There is no upper age limit for implants, provided you are healthy enough for a surgical procedure. Older adults may need extra assessment of their health conditions and medications, but age alone is rarely the deciding factor.
When extra treatment comes first
Some people need preparatory care before an implant can be placed:
- Bone grafting to add volume where bone has been lost.
- Gum treatment to bring active gum disease under control.
- Removal of a damaged tooth if it cannot be saved.
Saving a natural tooth is worth discussing before extraction. In some cases, Root Canal Therapy may allow you to keep the tooth instead of replacing it.
What Are the Benefits of Dental Implants Compared With Other Options?
The main benefits of dental implants are stability, protecting neighbouring teeth and helping to slow bone loss. Bridges and dentures remain reliable choices for many people, so the best option comes down to your mouth, health, budget and preferences.
How the options compare
| Feature | Dental Implant | Fixed Bridge | Removable Denture |
| Fixed or removable | Fixed | Fixed | Removable |
| Affects neighbouring teeth | Not usually, for a single implant | Usually, as supporting teeth are prepared for crowns | May use clasps on remaining teeth (partial dentures) |
| Effect on jawbone | Can help slow bone loss around the implant | Does not replace the tooth root | Does not replace the tooth root |
| Surgery required | Yes | No | No |
| Overall treatment time | Longer, due to healing | Shorter | Shorter |
| Daily care | Brush and clean around it like a natural tooth | Clean under the bridge daily | Remove and clean daily |
Benefits people often notice
- Stability: implants are anchored in the bone, so they are less likely to move when you talk or eat than a removable denture.
- Natural appearance: the crown is shaped and shaded to blend with your other teeth.
- Bone support: an implant places load on the jawbone in a similar way to a natural root, which can help slow the bone loss that often follows tooth loss.
- Less reliance on nearby teeth: a single implant stands on its own, so healthy teeth beside the gap usually do not need to be reshaped.
- More secure dentures: implant-supported dentures are held in place rather than resting only on the gums.
Trade-offs to consider
Implants involve surgery, a longer timeline and, often, a higher upfront cost than other options. Fees vary with the number of implants, any bone grafting, preparatory treatment, the crown material and your insurance. We provide a written cost estimate covering every stage before treatment begins, and it is worth checking with your insurer about what your plan includes.
What Happens During the Dental Implant Procedure?
The dental implant procedure usually happens in stages over several months: assessment, any preparatory care, implant placement, healing, and then fitting the final restoration. Knowing the dental implant treatment steps in advance makes the process feel more manageable.
Dental implant treatment steps
- Consultation and assessment. The dentist examines your mouth, reviews your health history and takes digital X-rays. A CBCT scan (a 3D X-ray) may be used where indicated to measure bone volume and plan the implant position.
- Preparatory treatment, if needed. This can include an extraction, gum treatment or bone grafting. Grafted bone needs time to heal before the implant is placed.
- Implant placement. The titanium post is placed in the jawbone under local anesthesia. Based on your clinical needs, this surgical phase may be coordinated with an oral surgeon or periodontist.
- Healing and integration. Over several months, the bone bonds with the implant. You may wear a temporary option during this time, depending on the location of the gap.
- Abutment placement. Once integration is confirmed, the abutment is attached to the implant.
- Final restoration. A custom crown, bridge or denture is made and fitted, then checked for fit, comfort and bite.
What recovery is usually like
Mild soreness and some swelling are common for a few days after placement. These are usually manageable with pain relief your dentist recommends. Soft foods, gentle cleaning around the area and following your post-operative instructions all help with healing.
Why imaging matters
Imaging shows the shape and density of the bone, along with the position of nearby structures such as nerves and sinuses. This helps the dentist plan the implant’s size, angle and position before treatment begins.
How Long Do Dental Implants Last With Proper Care?
Dental implants that are well maintained in sufficient bone can function for many years. The crown on top may need replacing at some point because of normal wear, even when the implant post itself stays stable. No implant is guaranteed to last a lifetime.
What affects how long an implant lasts
- Daily oral hygiene: plaque around an implant can inflame the surrounding gum and bone.
- Regular dental visits: checkups and professional cleanings help catch problems early.
- Smoking: smoking can affect healing and long-term implant health.
- Gum health: a history of gum disease raises the risk of problems around implants.
- Bite forces: clenching, grinding or chewing hard objects can strain the crown and implant.
- General health: conditions such as poorly controlled diabetes can affect healing.
Peri-implant disease
The biggest long-term threat to an implant is inflammation of the surrounding tissues. The American Academy of Periodontology explains that peri-implant diseases are inflammatory conditions affecting the soft and hard tissues around dental implants. Left untreated, this can lead to bone loss around the implant.
Daily care for your implant
- Brush around the crown twice a day with a soft-bristled toothbrush.
- Clean between the implant and the teeth beside it every day.
- Avoid chewing ice or biting hard objects.
- Keep every scheduled checkup.
- Report pain, looseness, swelling or changes in your bite promptly.

Frequently Asked Questions About Dental Implants
What are dental implants and how do they work?
Dental implants are titanium posts placed in the jawbone to replace the roots of missing teeth. Over several months, the bone bonds with the implant. An abutment is then attached, and a crown, bridge or denture is fitted on top to replace the visible tooth or teeth.
How long does it take to get a dental implant?
Implant treatment usually takes several months from start to finish. Most of this time is healing, while the bone bonds with the implant. If you need bone grafting or other preparatory care first, the overall timeline can be longer. Your dentist will outline the expected timing at your consultation.
Are dental implants better than dentures or bridges?
Implants are not better for everyone, but they offer specific advantages. They are fixed, can help slow bone loss and usually do not depend on neighbouring teeth. Bridges and dentures involve no surgery and take less time. Your bone, gums, health, budget and preferences decide the right choice.
Is dental implant surgery painful?
Implant placement is done under local anesthesia, so you should not feel pain during the procedure. Afterward, mild soreness and swelling are common for a few days. These are usually managed with pain relief your dentist recommends and by following your aftercare instructions.
How long do dental implants last?
With good oral hygiene, regular checkups and healthy gums, dental implants can function for many years. The crown on top may need replacing over time due to wear. Smoking, gum disease and grinding can shorten an implant’s lifespan, and no implant is guaranteed to last for life.
Conclusion
Dental implants replace missing teeth from the root up, giving you a fixed and stable result that can look and feel close to a natural tooth. They can support a single crown, a bridge or a denture, and they can help slow the bone loss that follows tooth loss. The trade-off is a longer treatment timeline and a surgical step, which is why a careful assessment matters.
If you are considering dental implants, the next step is a consultation to check your bone, gums and overall health. Request an appointment with Barton Dental to discuss your options.
