Dentures vs Dental Implants: Comparing Missing-Tooth Options

Dentures and dental implants both replace missing teeth, but they work in opposite ways. Dentures are removable and rest on your gums, while implants are fixed posts in the jawbone that hold crowns, bridges or even a denture in place. Dentures are usually quicker and cost less at the start; implants take longer and involve surgery, but they are more stable and help preserve bone.

For many people, the choice is not strictly one or the other. Some patients start with a denture and add implants later, and some use a few implants to anchor a denture. This guide compares the two options on the things patients ask about most: comfort, eating, speech, appearance, care, treatment time, longevity, cost and coverage in Ontario.

How do dentures work?

Dentures replace missing teeth with an appliance that sits on the gums. They are custom-made from impressions of your mouth, then adjusted for fit, bite and comfort.

• Complete dentures replace all the teeth in the upper or lower arch. The upper denture is held largely by suction against the palate; the lower denture rests on the ridge and is held by the cheeks, tongue and muscles.
• Partial dentures replace some teeth and use clasps or attachments on remaining natural teeth to stay in place.

You can compare the two types in complete dentures vs partial dentures, and our dentures page outlines the process at our office.

Dentures come out for cleaning and are usually removed overnight to give the gums a rest. Because the jawbone gradually changes shape after teeth are lost, dentures often need relining, adjustment or replacement over the years to keep a good fit. Our article on why dentures become loose explains why this happens.

How do dental implants work?

A dental implant replaces the root of a missing tooth with a small post, usually titanium, placed in the jawbone. After a healing period, during which bone bonds to the post, a restoration is attached on top. Depending on how many teeth are missing, that restoration may be:

• a single crown for one tooth,
• an implant-supported bridge for several teeth in a row, or
• a full-arch prosthesis or implant-retained denture for a whole upper or lower arch.

Because implants pass chewing forces into the bone, they help maintain the stimulation that keeps bone from shrinking. This is one of the most notable long-term differences from conventional dentures.

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.

Dentures vs implants at a glance

	Removable dentures	Dental implants
How they stay in	Rest on the gums; suction, clasps or adhesive	Anchored in the jawbone
Removable	Yes, for cleaning and at night	No (fixed options); implant-retained dentures snap in and out
Surgery	None	A surgical placement step
Typical timeline	Often weeks	Usually several months
Chewing	Good, with some adjustment to diet	Often closer to natural teeth
Bone	Bone under the denture tends to shrink over time	Helps preserve bone where implants are placed
Upkeep	Relines, adjustments and eventual replacement	Checkups, cleanings; crowns may need replacing
Upfront cost	Usually lower	Usually higher
CDCP	Complete dentures covered; partials need preauthorization	Not listed among covered services

This is a general comparison. Your own mouth, health and goals may shift the balance.

Which is more comfortable?

Comfort means different things with each option.

With dentures, the first weeks involve an adjustment period. Sore spots are common at first and are usually eased by small adjustments at follow-up visits. Your mouth may produce more saliva for a while, and the denture can feel bulky. Most people adapt, and our guide on how long it takes to adjust to new dentures describes what to expect.

With implants, there is some tenderness after placement, usually managed with over-the-counter pain relief as directed. Once healed, implant teeth do not rub on the gums or shift, which many patients describe as the biggest comfort difference. There is nothing covering the palate with fixed implant teeth, which some people find makes food taste and feel more natural.

Which is better for eating and speaking?

Eating. Implant-supported teeth usually allow a wider range of foods because they do not move under pressure. Denture wearers often cut food into smaller pieces and may avoid very hard, sticky or chewy foods, especially with a lower complete denture. Chewing with dentures improves with practice, but it rarely matches natural teeth.

Speaking. New dentures can affect some sounds, particularly “s” and “f,” until the tongue and lips adjust. Reading aloud at home helps. Implants generally have less effect on speech once treatment is complete, though any new restoration takes a little getting used to.

How do dentures and implants compare in appearance?

Both can look natural. Modern denture teeth come in many shapes and shades, and the pink base is made to resemble gum tissue. Implant crowns are shaped and coloured to match your other teeth.

The longer-term difference relates to bone. As bone shrinks under a denture over many years, the lower part of the face can lose some support, and the denture may need to be remade to restore that support. Implants may help limit bone loss in the areas where they are placed.

How long do dentures and implants last?

Neither option lasts forever, and no outcome can be guaranteed.

• Dentures often need relining every few years as the gums and bone change, and replacement after a longer period because the teeth wear and the fit changes. Regular checks allow small adjustments before problems develop.
• Implants are intended to be long term when the gums and bone around them stay healthy. The crown, bridge or denture attached to them may eventually need repair or replacement because of wear. Gum inflammation around implants is the main risk to watch for, which is why checkups and dental cleanings remain important.

What does care involve for each option?

Caring for dentures

• Remove and rinse after eating.
• Brush the denture daily with a denture brush and a non-abrasive cleaner.
• Soak overnight as directed, and store it in water or solution so it does not dry out.
• Brush your gums, tongue and any remaining teeth.
• Attend regular checkups so the fit, gums and oral tissues can be examined.

Our guide on how to clean and care for dentures walks through each step.

Caring for implants

Fixed implant teeth are brushed twice a day and cleaned between daily, much like natural teeth. Floss, interdental brushes or a water flosser can help around implant posts. Implant-retained dentures are removed for cleaning, and the attachments on the implants are brushed as well. Regular professional cleanings and exams let your dental team check the gum and bone health around each implant.

What about implant-supported dentures?

For patients missing many or all teeth, implant-supported dentures combine features of both options. A small number of implants are placed in the jaw, and the denture clips or snaps onto them.

Potential advantages include:

• noticeably more stability than a conventional denture, especially on the lower jaw,
• less reliance on adhesives,
• fewer implants than a fully fixed set of implant teeth, which can reduce cost,
• in some cases, the ability to adapt an existing denture.

The denture still comes out for cleaning, and the attachments wear over time and need periodic replacement. Whether this approach is feasible depends on your bone volume, health and the assessment.

Who is a good candidate for dentures, and who for implants?

Dentures may suit you if:

• you are missing many or all teeth and want a quicker solution,
• surgery is not an option for medical or personal reasons,
• bone volume is limited and grafting is not appealing,
• upfront cost is the main concern,
• you want the flexibility to add implants later.

Implants may suit you if:

• you have enough healthy bone, or are willing to consider grafting,
• your gums are healthy, or gum disease can be treated first,
• general health conditions affecting healing are well managed,
• stability and chewing ability are high priorities,
• you are comfortable with a treatment timeline of several months.

Smoking, uncontrolled diabetes and some medications can affect implant healing. Your dentist will review your health history and talk openly about these factors. If you have worn dentures for a long time, bone shrinkage may need to be considered; our article on dental implants after bone loss explains the options.

How do costs and coverage compare in Ontario?

Cost factors

Neither option has a single fixed price. For dentures, cost depends on whether you need complete or partial dentures, any extractions first, the materials and follow-up adjustments. For implants, it depends on the number of implants, extractions, bone grafting, imaging and the type of restoration. Our dental implant cost guide breaks down each part of an implant estimate. At York Street Dental Centre, we explain findings, options, alternatives and estimated fees before treatment begins.

Insurance and the CDCP

• Private insurance varies. Some plans cover dentures at a set percentage, some cover part of implant treatment, and some exclude implants. A predetermination sent to your insurer before treatment shows your share. We offer direct insurance billing for many plans.
• The Canadian Dental Care Plan covers complete dentures, and partial dentures require preauthorization. Dental implants are not listed among CDCP covered services. For many CDCP patients, this means a denture may be covered while implants would be paid out of pocket or through other coverage. Check the current coverage list or ask us what applies to you.

Tax credit

The Canada Revenue Agency lists both dentures and dental implants as eligible medical expenses for the medical expense tax credit. You can claim eligible amounts paid in any 12-month period ending in the tax year, above the lesser of 3% of your net income or a fixed amount set by the CRA. Keep your receipts from every stage.

Can you switch from dentures to implants later?

Often, yes. Many people wear a denture for years before deciding to explore implants, and starting with a denture does not rule them out. What changes over time is the bone. The longer an area has been without teeth, the more the ridge may have narrowed or flattened, which can affect where implants can go and whether grafting would be needed first.

If you think you may want implants in future, a few steps help keep that door open:

• mention it when your denture is being planned, so your dentist can take it into account,
• keep up regular checkups, where X-rays can track changes in the bone,
• have a loose or rocking denture relined or adjusted rather than living with it, since a poor fit can irritate the gums,
• ask whether your existing denture could later be converted to snap onto implants.

An assessment with current imaging is the only way to know what is realistic at that time.

What if you are facing extractions?

If several teeth need to come out, it is worth discussing replacement before the extractions happen. The plan may affect which teeth are kept, whether an immediate denture can be worn during healing, and where implants could go later. Our tooth extraction page explains what removal involves.

Some patients choose a denture first, then add implants to stabilize it once healing is complete and the budget allows. Keeping future options open is a reasonable strategy.

Talking through dentures and implants in Cornwall

Choosing between dentures and implants is easier when you can see your own X-rays and hear the options explained plainly. At our office at 118 York Street, we assess your bone, gums and remaining teeth, then compare what dentures, implant-supported dentures and fixed implant teeth would involve for you.

We see many seniors and adults from Cornwall neighbourhoods such as Riverdale and Churchill Heights, as well as from St. Andrews West, Lakeview Heights and Cornwall Island (Akwesasne). We welcome eligible CDCP patients and can help you understand which parts of your plan may be covered before you decide.
