Dental Implants – Frequently Asked Questions (FAQ)

Quick answer: A dental implant is a small titanium post that replaces a tooth root and supports a crown, bridge or full arch. Long-term studies show most implants are still in place after 10 years. Results depend on healthy gums, good bone, not smoking, regular cleanings and a careful plan made around your mouth.

She came in with a list on her phone.

Twenty-two questions. She had been collecting them for months, ever since a back tooth cracked and had to come out. How long would an implant last? Could it fail? Would it get infected? What if she just waited?

Every website she found answered a few of them, then tried to sell her something.

If you have your own list, this article is for you. We picked the questions patients ask us most often and answered them as plainly as we can.

The simple answer is… dental implants are one of the most reliable ways to replace a missing tooth, and most people who get them keep them for many years.

The more honest answer is… implants are not maintenance-free, they are not right for every mouth, and the result depends a lot on what happens before and after the surgery.

What Exactly Is a Dental Implant?

An implant has three parts.

• The implant post. A small screw-shaped post placed in the jawbone where the root used to be.
• The abutment. A connector that sits on top of the post, just above the gum.
• The restoration. A crown for one tooth, a bridge for several, or a full arch of teeth.

Over a few months, the bone heals tightly around the post. That bond is what lets an implant handle chewing forces much like a natural root. Our dental implants page walks through each stage of treatment.

How Long Do Dental Implants Last?

This is the question we hear most, and the research here is strong.

A systematic review of studies that followed patients for 10 years found that 96.4% of implants were still in place (Howe et al., 2019). When the authors adjusted for patients who dropped out of the studies, the estimate was 93.2%, which is probably closer to real life.

A 2026 review looked even further out. Across studies following patients for 10 to 25 years, about 95% of implants survived (Moraschini et al., 2026).

The post tends to outlast the tooth on top of it.

In a review of single implant crowns, 95.2% of implants survived at 10 years, while 89.4% of the crowns themselves were still in service (Jung et al., 2012). Crowns can chip, wear or come loose, and sometimes need to be remade. That is why our implants page describes the crown as lasting about 10 to 15 years, while the implant itself can last much longer with good care.

Can a Dental Implant Fail?

Yes. It is uncommon, but it happens.

Implants can fail early, when the bone never bonds to the post, or later, after years of use. Late problems are usually tied to infection around the implant or too much force on it.

Some factors raise the risk more than others.

• Smoking. In a review of more than 80,000 implants, 6.35% failed in smokers compared with 3.18% in non-smokers. Smokers also had more infections after surgery and more bone loss around their implants (Chrcanovic et al., 2015).
• Diabetes. The same research group found that diabetes did not significantly change implant failure rates, but people with diabetes did lose slightly more bone around their implants (Chrcanovic et al., 2014). Good blood sugar control matters.
• Gum disease and plaque. Bacteria that cause gum disease can also attack the tissue around an implant.
• Heavy biting forces. Clenching and grinding put extra stress on implants and crowns.

If you have been told one of these factors rules you out, our article on what to do if you are told you are not a candidate for implants explains which ones can often be treated first.

Can Dental Implants Get Infected?

They can. The infection is called peri-implantitis, and it is the main long-term risk with implants.

It starts like gum disease. Plaque builds up, the gum around the implant gets inflamed, and if nothing changes, the bone holding the implant can start to break down. In a review of studies on how common this is, the average prevalence of peri-implantitis was estimated at 22% of patients, though the numbers varied widely depending on how each study defined it (Derks & Tomasi, 2015). A 2026 review that only included patients followed for at least 10 years reported peri-implantitis around 10.8% of implants on average (Moraschini et al., 2026).

Those numbers are not meant to scare you.

They are the reason cleanings and home care still matter after you get an implant.

Implants cannot get cavities, but the gums and bone around them can still get sick. If you have had gum disease before, treating it with periodontal care before your implant is an important step.

Why Not Just Leave the Gap?

Many people wonder whether replacing a missing tooth is really necessary, especially a back tooth no one can see.

Here is what research shows. After a tooth is removed, the jawbone in that area starts to shrink. In human studies, the ridge lost 29% to 63% of its width and 11% to 22% of its height within about six months, with the fastest changes in the first three to six months (Tan et al., 2012).

Less bone can make an implant harder to place later. It can mean extra steps, such as grafting.

Neighboring teeth may also drift into the space over time, which can change your bite. For back teeth specifically, our article on how molar implants restore your chewing power explains why the gap matters for everyday eating.

The Biggest Difference: Implants, Bridges and Dentures

All three replace missing teeth. The difference is what holds them in place.

A dental bridge can be a great choice when the teeth next to the gap already need crowns. Full and partial dentures are a non-surgical option and cost less up front.

When all teeth are missing, implants can also be used to anchor dentures. In a meta-analysis of randomized trials, people with lower dentures held in place by implants were more satisfied than people with conventional dentures (Emami et al., 2009).

If you are weighing a full-arch solution, our article on facts and myths about full mouth reconstruction clears up the most common misunderstandings.

Does Getting an Implant Hurt?

Most patients tell us it was easier than they expected.

The area is numbed, and many patients feel pressure rather than pain. For anxious patients or longer procedures, we offer sedation options, including nitrous oxide, oral sedation and IV sedation.

Mild soreness and swelling for a few days afterward is normal. Our dental implant post-op instructions cover what to expect day by day and when to call us.

How Long Does the Whole Implant Process Take?

For a typical single implant, plan on about three to six months from start to finish.

That time is mostly healing, not appointments. A common path looks like this:

• Planning. An exam, 3D imaging and a conversation about your goals.
• Preparation, if needed. Extractions, gum treatment or bone grafting come first when they are needed.
• Placement. The implant post is placed in the jaw.
• Healing. The bone bonds to the post over several months.
• Final tooth. The abutment and custom crown are attached.

If grafting is needed, the timeline can stretch longer, because the new bone needs to mature before it can support an implant.

Can I Get Teeth the Same Day as My Implant?

Sometimes.

If the implant is very stable when it is placed and your bite allows it, a temporary tooth can sometimes be attached the same day. Not every case qualifies. This is something we can tell you during planning, once we see your bone on a 3D scan.

Either way, the implant still needs a few months to fully bond with the bone before the final crown goes on.

Is There an Age Limit for Implants?

No. In a meta-analysis of implants in adults 65 and older, 96.2% survived at 5 years and 91.2% at 10 years, and the authors concluded that age alone should not limit implant treatment (Srinivasan et al., 2017).

General health, medications and bone quality matter far more than the number of birthdays.

What We Look at Before Recommending Dental Implants

Every implant plan we make in Clifton starts with the same questions.

• How much bone is there? Our 3D cone beam CT imaging shows the height and width of the bone and where nerves and sinuses sit.
• Are the gums healthy? Active gum disease is treated first.
• What is your health history? Diabetes control, medications and past treatment can all change the plan.
• Do you smoke or grind? Both affect healing and long-term results.
• What are you replacing? A single-tooth implant is planned very differently from a full arch.

From there, we explain what is realistic for your mouth, including the options that do not involve implants.

What Are the Risks and Limits of Dental Implants?

Implants are reliable, but no treatment is risk-free. Before you decide, it helps to know:

• Like any oral surgery, implant placement can involve swelling, bruising, bleeding and, rarely, infection or nerve irritation.
• A small share of implants fail, and smokers face a higher risk (Chrcanovic et al., 2015).
• Infection around implants is a real long-term risk, especially with poor plaque control (Derks & Tomasi, 2015).
• Crowns and other parts can chip, loosen or wear and may need repair over time (Jung et al., 2012).
• Treatment takes months, not days, and may need extra steps if bone is thin.
• Implants are not ideal for everyone. A bridge or denture may be the better fit for some people.

How Much Do Dental Implants Cost?

The price depends on how many teeth you are replacing and whether you need extra steps first. These ranges come from our service pages.

• Single implant (implant, abutment and crown): $3,000 to $6,000
• Same-day implant: $3,500 to $6,500 per tooth
• Bone graft, if needed: $300 to $1,200 per site
• All-on-X full arch: $20,000 to $35,000 per arch

Your estimate will be specific to you after an exam and imaging. We accept most PPO plans, and some plans cover part of the crown. Our guide to what dental implant insurance covers explains what to ask your insurer. We also offer financing through Cherry and CareCredit.

Final Takeaways

• A dental implant replaces the tooth root and supports a crown, bridge or full arch.
• Long-term studies show about 93% to 96% of implants still in place after 10 years.
• The crown on top may need replacing before the implant itself does.
• Smoking roughly doubles the failure rate seen in non-smokers.
• Infection around implants is the main long-term risk, so cleanings still matter.
• Bone shrinks after a tooth is lost, so waiting can make treatment harder.
• Age alone is not a reason to rule out implants.
• Bridges and dentures are still good options for some people.
