Implant-Supported Dentures vs. Traditional Dentures in Oakville

Dentures | Shore Side dental Oakville

Traditional dentures rest on your gums and are held by suction, a close fit or clasps, so they can shift while you eat or speak. Implant supported dentures attach to small titanium posts placed in the jawbone, which usually makes them more stable and helps preserve the bone underneath. The right choice depends on your bone, gum health, general health, budget and goals.

How Traditional Dentures Work

A traditional denture is a removable appliance made of an acrylic base that looks like gum tissue, with artificial teeth set into it. There are two main types:

  • Complete dentures replace all of the teeth in the upper or lower jaw. An upper denture covers the roof of the mouth, which helps create suction. A lower denture is horseshoe-shaped so there is room for the tongue, which means it has less surface to grip.
  • Partial dentures replace some teeth when healthy natural teeth remain. They usually use metal or tooth-coloured clasps that hook around the remaining teeth for support.

Dentures are a well-established, non-surgical way to restore appearance and function, and they remain a good option for many people. You can learn more on our dentures page.

The limits of conventional dentures

  • Movement: Because the denture sits on soft tissue, it can lift, rock or slide when you bite into firm foods, laugh or speak. Lower dentures are often the hardest to keep in place.
  • Adhesives: Many wearers rely on denture creams or powders to feel secure. These can help, but they need to be cleaned off daily and do not solve a poor fit.
  • Reduced chewing force: Many people find they avoid certain foods, such as raw vegetables, nuts or tougher meats.
  • Bone resorption: This is the change people notice least at first but that matters a great deal over time.

Why the jawbone shrinks after tooth loss

The bone that holds your teeth (the alveolar ridge) is maintained partly by the forces passed through tooth roots when you chew. Once teeth are lost, that stimulation stops and the ridge gradually shrinks in height and width. As the ridge shrinks, a denture that once fit well becomes loose, needs relining or remaking, and the lower face can start to look shorter or more sunken.

How Implant Supported Dentures Work

A dental implant is a small titanium (or sometimes zirconia) post placed in the jawbone, where it acts like an artificial root. Over several months the bone bonds to the implant surface, a process called osseointegration. Once healed, the implants can anchor a denture. You can read more about the implants themselves on our dental implants page.

Snap-on overdentures (implant-retained, removable)

An overdenture looks much like a regular denture, but its underside has attachments that click onto matching fittings on the implants or onto a small bar connecting them. You remove it for cleaning and usually at night. Because the implants hold it in place, it typically moves much less than a conventional denture.

Fixed implant bridges (implant-supported, non-removable)

A fixed full-arch bridge is screwed or secured onto the implants and is not taken out at home. Only your dental team can remove it, usually for maintenance. It feels closer to natural teeth, but it generally requires more implants and more bone, and it costs more.

How many implants are needed?

The number varies with the jaw, the bone available and the type of denture. In general terms, a lower overdenture often uses two to four implants, while a fixed bridge usually needs more. Upper dentures often need more implants than lower ones because the upper bone is typically softer. Your dentist will advise on the number that suits your situation after an examination and 3D imaging.

Comparing Comfort, Chewing, Speech and Cleaning

Comfort and confidence

Many patients find that an implant supported denture feels more secure, with less rubbing and fewer sore spots, because the implants take much of the load instead of the gums alone. Adhesives are usually no longer needed.

Chewing

Because the denture is anchored, you can usually bite and chew with more force and confidence. Many people find they can return to a wider range of foods.

Speech

A loose denture can click or shift when you speak, especially with sounds like “s” and “f”. An anchored denture is less likely to move, which often makes speaking feel more natural.

Cleaning and maintenance

  • Traditional dentures: Remove and brush daily with a soft brush and a non-abrasive denture cleaner, soak overnight, and clean your gums and tongue.
  • Snap-on overdentures: Clean the denture the same way, plus brush carefully around the implant fittings. The small nylon inserts in the attachments wear over time and are replaced periodically.
  • Fixed bridges: Clean under and around the bridge each day using tools such as a water flosser, interdental brushes or special floss.

Implants do not decay, but the gum and bone around them can become inflamed, a condition called peri-implantitis. Daily cleaning and regular professional visits are important for keeping implants healthy over the long term.

Who Is a Candidate for Implant Supported Dentures?

Many adults who are missing most or all of their teeth can be considered. During your assessment, your dentist will check:

  • Bone volume and quality: There needs to be enough bone in the right places to hold the implants. This is measured with digital X-rays and usually 3D imaging.
  • Gum health: Active gum disease needs to be treated and stable before implants are placed.
  • General health: Conditions such as uncontrolled diabetes, some bone medications, certain cancer treatments, or a weakened immune system can affect healing. These do not always rule out implants, but your dentist may need to coordinate with your physician.
  • Smoking: Smoking can slow healing and raise the risk of implant problems. Quitting or cutting back is strongly encouraged.

At Shore Side Dentistry, Dr. Tina Kokosis, our certified specialist in periodontics, can assess the gums and supporting bone and help plan implant placement, especially when gum disease or bone loss is a concern.

What if there is not enough bone?

If years without teeth have caused the ridge to shrink, bone grafting may be recommended to rebuild the area before or at the same time as implant placement. In the upper back jaw, a sinus lift can add bone below the sinus. Grafting adds healing time and cost, so it is discussed in detail before treatment.

The Treatment Timeline and Visits

Every plan is different, but implant dentures usually follow these stages:

  1. Consultation and records: An exam, X-rays and often 3D imaging, plus a discussion of your health history and goals. Digital impressions may be taken with our iTero intraoral scanner.
  2. Treatment planning: Your dentist designs the denture and plans implant positions. Any extractions, gum treatment or grafting are scheduled first.
  3. Implant placement: The implants are placed under local anaesthetic. Nitrous oxide sedation is available at our office for patients who feel anxious.
  4. Healing: Osseointegration typically takes a few months, longer if grafting was needed. You usually wear a temporary or adjusted denture during this time.
  5. Attaching the final denture: Once the implants are integrated, the final overdenture or fixed bridge is fitted and adjusted for your bite.
  6. Follow-up and maintenance: Regular checkups and cleanings to monitor the implants, gums and denture fit.

From start to finish, many patients complete treatment over several months to a year, depending on healing and whether grafting is required.

Implant Supported Dentures Cost: What Affects the Price

As a general range, not a quote, a single dental implant with a crown costs about $800 to more than $5,000. A full-arch implant denture is a different kind of treatment, and its cost depends on the number of implants and the type of denture (snap-on overdenture or fixed bridge). A consultation is needed before we can give you an accurate quote. Factors that affect the fee include:

  • How many implants are needed, and in one or both jaws
  • Whether you choose a removable overdenture or a fixed bridge
  • Extractions, bone grafting or sinus lifts
  • Imaging, temporary teeth and sedation
  • Whether your existing denture can be converted

Dental insurance may cover part of the treatment depending on your plan. Eligible seniors may also want to look into the Ontario Seniors Dental Care Program or the federal Canadian Dental Care Plan; check current eligibility and coverage details directly with each program.

Can My Existing Denture Be Converted?

Sometimes, yes. If your current denture fits well, the teeth are in good condition and the bite is correct, your dentist may be able to modify it by adding attachments that snap onto new implants. If the denture is worn, loose or poorly fitting, a new one is usually recommended so the final result works well with the implants. Your dentist will check this at your consultation.

Implant Dentures for Seniors

Age alone is not usually a barrier to implants. Many older adults are good candidates if their general health allows minor oral surgery and healing. For seniors, the benefits of a stable denture can be practical: easier chewing can support a varied diet, and a secure fit can make social meals more comfortable. A snap-on overdenture is often a good fit because it is easier to clean than a fixed bridge, which matters for anyone with limited hand dexterity.

Frequently Asked Questions

Are implant supported dentures better than regular dentures?

They are usually more stable and help preserve jawbone, but they require surgery, healing time and a higher investment. Regular dentures remain a reasonable choice for many people. Your dentist will explain which option suits your bone, health and goals.

How long do implant supported dentures last?

With good home care and regular checkups, implants can last many years. The denture itself wears over time and may need relining, new attachment inserts or replacement.

Is getting implant dentures painful?

Implant placement is done with local anaesthetic, so the area is numbed and most people feel pressure rather than pain during the procedure. Afterward, most people have some soreness and swelling for a few days that is usually managed with over-the-counter pain relievers. Nitrous oxide sedation is available for anxious patients.

Can I sleep with snap-on dentures?

Dentists usually recommend removing an overdenture at night so the gums can rest and the denture and implants can be cleaned.

How much are implant supported dentures in Ontario?

The cost depends on the number of implants, the type of denture and whether grafting or extractions are needed. As a general range, a single implant with a crown is about $800 to more than $5,000, and a full-arch plan is quoted after a consultation.
