How long do dental implants last?

Peer-reviewed research reports about 86% of implants still functioning at 15 years, and well-placed implants routinely last decades. In our practice, more than 97% of patients still have a healthy implant after 20 or more years. Placement precision, restoration quality, and maintenance drive the difference.

How long do dental crowns last?

Typical crowns last 5 to 20 years depending on fabrication quality, fit, and care. Insurance plans assume replacement after 5 years. Custom crowns fabricated in our in-house laboratory, with verified margins and adjusted bites, have lasted more than 35 years.

How long do porcelain veneers last?

Research shows a veneer survival rate of approximately 91% at 20 years. Longevity depends on sound bonding to enamel, correct case selection, bite protection, and the quality of fabrication.

What shortens the life of dental restorations?

The usual suspects are imprecise fit that lets decay start at the margins, unbalanced bite forces, untreated grinding or clenching, gum disease, and skipped maintenance visits. Most of these are controllable, which is why identical restorations can last 8 years in one mouth and 30 in another.

Should aging restorations be replaced before they fail?

Often, yes. Restorations placed 15 or 20 years ago can be monitored while sound, but staining margins, recurring sensitivity, or visible wear are signals worth evaluating. Replacing aging dentistry on your schedule is calmer, cheaper, and more predictable than replacing it as an emergency.

How Long Dental Restorations Last

Dental restorations, implants, crowns, and veneers, restore missing, damaged, and severely discolored teeth. When you invest in them, you deserve a straight answer to a fair question: how long will this last?

The honest answer has two parts. Published research gives the averages. Fabrication and placement quality decide whether your restorations live at the average or far beyond it. Here are both numbers, category by category.

Dental Implants

Research shows that after 15 years, about 86% of dental implants remain in place [1]. That is a strong baseline, and it understates what careful work achieves.

Implant longevity is decided at the start: three-dimensional planning, precise placement in adequate bone, and a properly engineered restoration on top. At Elite Prosthetic Dentistry, more than 97% of our patients still have a healthy implant after 20+ years, well above the published average. Dr. Marlin has placed and restored over 3,900 implants across a career spanning more than 40 years, and pairs each with a custom restoration from our in-house laboratory so the implant and its crown work as one engineered system.

Dental Crowns

Typical crowns last anywhere from 5 to 20 years, and insurers will pay to replace one after just 5, a quiet admission of what average fabrication achieves. The failure mode is rarely the ceramic itself. It is the fit: margins that do not seal invite decay beneath the crown, and bites that were never balanced overload the restoration and the tooth.

Our crowns are custom fabricated on-site by experienced technicians who work directly with you and with Dr. Marlin, then verified for marginal fit and X-rayed at seating. The result of that discipline: crowns from our laboratory have lasted more than 35 years with proper care. The full process is documented in how we create a dental crown that lasts 35 years, and the comparison with typical work in how long a dental crown should last.

Porcelain Veneers

Veneers, correctly selected and bonded, are impressively durable: research shows a survival rate of 91% after 20 years [2]. The qualifiers matter. Veneers depend on sound enamel bonding and sensible case selection, and they fail early when asked to mask very dark teeth or bond to exposed root surface, situations where a crown is the better instrument. Like everything we place, our veneers are fabricated in-house and matched to your smile individually.

How to Make Your Restorations Last

Three decisions, made once, control most of the outcome.

Choose a specialist. A prosthodontist completes years of additional training beyond dental school specifically in restoring and replacing teeth, from single crowns through full-mouth reconstruction. Position, fit, and bite engineering are exactly the variables that separate 8-year dentistry from 30-year dentistry.

Choose custom, in-house fabrication. When the technician who builds your restoration can see you, verify fit with the dentist, and remake anything imperfect the same week, quality control is real rather than contractual. That is the standard our laboratory has kept since 1985.

Maintain the investment. Brush and floss daily, wear a nightguard if you grind, and keep regular checkups and professional cleanings so decay, gum disease, and bite changes are caught early. Restorations do not get cavities, but the teeth and gums holding them do.

Thinking About the Whole Mouth, Not One Tooth

Restorations age together. Patients often come to us with a mix: a crown from 2005, a bridge from 2012, a veneer that never quite matched. Treatment ranges from replacing a single older crown to coordinated reconstruction, depending on what evaluation shows and what you want. Many patients simply want dentistry that looks natural, functions properly, and lasts, and choose to replace aging work thoughtfully, on their own schedule, rather than reactively. A real example: aging crowns and a failing bridge rebuilt with coordinated reconstruction.
