Losing a tooth changes more than your smile. It shifts how you chew, how you speak, and over time, how your face looks. Whether you've lost teeth to decay, gum disease, or an accident, the gap left behind creates problems that compound with each passing year.
The good news? You have real options. Dentures and bridges for missing teeth represent two of the most established, effective solutions available, and both have evolved significantly from what your grandparents might remember. Modern prosthetics look natural, fit comfortably, and restore function in ways that genuinely improve quality of life.
But choosing between them isn't straightforward. Your decision depends on how many teeth you've lost, where they're located, your budget, your lifestyle, and what your remaining teeth can support. A bridge might be perfect for someone with a single missing tooth flanked by healthy neighbors, while dentures make more sense when multiple teeth are gone or the supporting structure can't handle fixed restoration.
I've seen patients agonize over this choice, worried they'll make the wrong call. Here's what matters: both options work. The real question is which works better for your specific situation. Understanding what each involves, from placement to daily maintenance to long-term costs, puts you in a position to have a productive conversation with your dentist and make a decision you'll feel good about for years.
The Importance of Replacing Missing Teeth
Gaps in your smile aren't just cosmetic concerns. They trigger a cascade of changes throughout your mouth that accelerate over time, making treatment more complicated and expensive the longer you wait.
Impact on Oral Health and Bone Structure
Your jawbone needs stimulation to maintain its density. Tooth roots provide that stimulation through chewing pressure. When a tooth disappears, the bone beneath it starts resorbing, sometimes losing 25% of its width within the first year alone. This bone loss doesn't stop; it continues indefinitely, eventually affecting neighboring teeth and changing the foundation available for any future restoration.
Remaining teeth also shift. They drift toward gaps, tilting and rotating in ways that create bite problems and hard-to-clean spaces where decay thrives. A single missing molar can destabilize an entire arch within a few years.

Restoring Facial Aesthetics and Confidence
Beyond function, missing teeth affect appearance in ways people don't always anticipate. Lips lose support and fold inward. Cheeks hollow. The distance between nose and chin shrinks as bone deteriorates. These changes age faces dramatically, sometimes by a decade or more.
The psychological impact runs equally deep. Many people with missing teeth avoid smiling, speaking in groups, or eating in public. Restoring those teeth doesn't just fix mechanics; it returns confidence that affects relationships, career opportunities, and overall wellbeing.
Dental Bridges: A Permanent Solution for Gaps
Bridges literally bridge the gap left by missing teeth, using adjacent teeth as anchors for a fixed prosthetic that stays in your mouth permanently. They've been a reliable solution for over a century, and modern materials have made them more natural-looking and durable than ever.
Traditional and Cantilever Bridge Variations
The most common type, a traditional bridge, uses crowns placed on teeth on both sides of the gap to support a false tooth (called a pontic) in between. This three-unit structure distributes chewing forces across multiple teeth, providing stability and strength.
Cantilever bridges work differently, anchoring to teeth on only one side of the gap. They're useful when healthy teeth exist on just one side, though they create more leverage stress and typically work best for front teeth where chewing forces are lighter.
Maryland bridges offer another variation, using metal or porcelain wings bonded to the backs of adjacent teeth rather than full crowns. They preserve more natural tooth structure but sacrifice some strength.
The Procedure: Preparation and Placement
Getting a bridge typically requires two appointments spread over two to three weeks. During the first visit, your dentist reshapes the anchor teeth, removing enough enamel to accommodate crowns. Impressions go to a lab where technicians craft your custom bridge.
You'll wear a temporary bridge while waiting for your permanent one. At the second appointment, your dentist checks the fit, makes adjustments, and cements the bridge permanently. Most patients adapt to their new bridge within a few days.
Dentures: Removable Options for Multiple Missing Teeth
When multiple teeth are missing or remaining teeth can't support a bridge, dentures provide a removable solution that replaces teeth and surrounding gum tissue. Modern dentures bear little resemblance to the clunky, obvious prosthetics of decades past.
Full vs. Partial Dentures
Full dentures replace all teeth in an arch, sitting directly on the gums and staying in place through suction and sometimes adhesive. They work for patients who've lost all their teeth or whose remaining teeth are too compromised to save.
Partial dentures fill gaps while working around existing teeth. They use metal or plastic frameworks with clasps that grip remaining teeth for stability. Partials prevent remaining teeth from shifting while restoring chewing function and appearance.
Both types require adjustment periods. Speaking and eating feel different at first, and your mouth needs time to adapt. Most patients feel comfortable within a few weeks, though some adjustments are typically necessary during the first months.
The Role of Implant-Supported Overdentures
Implant-supported overdentures represent a significant advancement. Rather than resting entirely on gums, these dentures snap onto dental implants surgically placed in the jawbone. Even two implants dramatically improve stability, eliminating the slipping and clicking that frustrates many traditional denture wearers.
The implants also preserve bone by providing the stimulation that prevents resorption. While more expensive initially, overdentures often prove more cost-effective over time because they reduce bone loss, adjustment needs, and the frequency of denture replacement.
Comparing Bridges and Dentures
Both solutions restore function and appearance, but they differ significantly in how they achieve those goals and what they require from you long-term.
Durability and Longevity Expectations
Well-maintained bridges typically last 10 to 15 years, with some lasting decades. Their fixed nature protects them from the wear and handling damage that affects removable prosthetics. However, the anchor teeth bear additional stress and remain vulnerable to decay at crown margins.
Traditional dentures need replacement every 5 to 7 years as bone changes alter their fit. Implant-supported overdentures last longer, with the implants themselves often lasting a lifetime while the denture portion requires periodic replacement.
Cost Considerations and Insurance Coverage
Bridges generally cost between $2,000 and $5,000 per tooth replaced, depending on materials and location. Insurance often covers 50% after deductibles, though maximums may limit actual benefits.
Complete dentures range from $1,000 to $3,000 per arch for conventional versions, with implant-supported options running $15,000 to $30,000. Partials fall between $700 and $1,800. Insurance coverage varies widely, and many plans consider dentures a major service with higher out-of-pocket requirements.
Maintenance and Long-Term Care
Both bridges and dentures require consistent care to maximize their lifespan and protect your oral health.
Daily Cleaning Routines for Prosthetics
Bridges need the same twice-daily brushing as natural teeth, with special attention to where crowns meet gums. Floss threaders or water flossers help clean beneath the pontic where food and bacteria accumulate. Neglecting this area leads to decay in anchor teeth and gum disease.
Dentures require removal and brushing with a soft brush and denture cleaner, never regular toothpaste, which is too abrasive. Soak them overnight in denture solution to kill bacteria and prevent warping. Clean your gums, tongue, and any remaining teeth thoroughly before reinserting dentures each morning.
Professional Adjustments and Relining
Your mouth changes over time, and prosthetics need adjustment to match. Bridges may need recementation or replacement if anchor teeth develop problems. Regular dental visits catch issues early, before they become expensive failures.
Dentures require relining every one to two years as bone resorption changes their fit. Poorly fitting dentures cause sore spots, difficulty eating, and accelerated bone loss. Don't ignore discomfort or looseness; these signal the need for professional attention.
Choosing the Right Treatment for Your Smile
The best choice depends on your specific circumstances. Bridges work well when you're missing one to three adjacent teeth and have healthy neighbors to support crowns. They feel natural, require no removal, and provide excellent chewing function.
Dentures make sense when you're missing many teeth, lack adequate anchor teeth, or need a more affordable solution. Modern partials and implant-supported options address many traditional denture complaints.
Consider your priorities honestly. How important is avoiding removable prosthetics? What can you realistically afford, including long-term maintenance? How much bone loss has already occurred? Your dentist can assess your specific situation and recommend the approach most likely to succeed.
Whatever you choose, taking action matters more than finding the perfect solution. Every month without replacement allows more bone loss and tooth shifting. Both bridges and dentures can restore your smile, your confidence, and your ability to eat the foods you love. The right time to address missing teeth is now.
