Am I a Candidate for Dental Implants? What Dentists Check

Being a candidate for dental implants isn't a label you're born with. It's a picture of your gums, jawbone, and health on the day you're examined, and it can change. At Peterborough Family Dental & Implant Center in Peterborough, NH, we place and restore dental implants, and we tell patients early that "not yet" is a common answer. A flat "no" is less common than most people expect.

About 120 million Americans are missing at least one tooth, according to the American College of Prosthodontists. Many assume implants are out of reach because a friend was turned down or a dentist once mentioned bone loss. Sometimes that's true. Often it isn't the full story.

Here's what dentists actually look at, what can be fixed, and what a consultation involves, so you know where you stand before you book.

What Makes Someone a Good Candidate for Dental Implants?

A good candidate for dental implants has healthy gums, enough jawbone to hold a post, good general health, and a fully developed jaw. Habits like smoking and daily oral hygiene also matter. No single factor decides it, because your dentist weighs them together after an exam and a 3D scan.

Why does that care matter? Success depends partly on choosing the right patients. The Journal of Oral and Maxillofacial Surgery reports implant success rates of 95-98% over 10 years, and careful screening is a big part of that number.

• Healthy gums: Infection around an implant can damage the bone that holds it, so gum health comes first.
• Enough bone: The post needs bone in both height and width to stay stable while it heals.
• Good general health: Your body has to heal from a minor surgical procedure.
• A fully grown jaw: Placement waits until jaw growth is complete.
• Willingness to keep up care: Daily cleaning and regular checkups protect the implant for years.

Most people want implants for the same reason. The American Academy of Implant Dentistry reports that implant-supported teeth can restore up to 90% of natural chewing power, which is why patients tell us they stop thinking about their teeth at meals.

How Does Your Jawbone Affect Whether You Qualify?

Your jawbone matters because an implant needs enough bone, in both height and width, to hold the post steady while it heals. After a tooth is lost, the bone in that spot slowly shrinks, so the longer a gap has been there, the more likely it is that bone needs attention.

A regular X-ray shows a flat picture. A 3D CBCT scan shows depth. It lets the dentist measure bone volume, find nerves and sinuses, and plan where each post should go. That's why we take one at the consultation, before anyone talks about treatment.

What does a bone graft involve?

A bone graft adds bone material to a thin area so it can support an implant. Healing usually takes a few months, and then the implant can be planned. Many patients are surprised to learn that a graft can turn a "no" into a "yes."

Can you get implants after years without a tooth?

Often, yes. Years without a tooth usually mean less bone, but not always. Some people keep plenty. Only the scan can tell you which group you're in.

Can You Get Dental Implants With Gum Disease?

Yes, but only after the gum disease is treated and under control. Implants need healthy tissue around them, because infection near an implant can damage the bone that holds it. Most patients start with a deep cleaning, then return for implants once their gums have healed.

This comes up often. The CDC reports that 42% of adults aged 30 and older have some form of periodontal disease. The National Institute of Dental and Craniofacial Research describes gum disease as an infection that, if left untreated, can spread to the bones supporting the teeth. Similar infections can affect the tissue around an implant.

Here is the usual path from gum disease to implants.

1. Your dentist examines your gums, measures pocket depths, and takes X-rays.
2. You receive a deep cleaning, called scaling and root planing, to remove bacteria below the gumline.
3. The team rechecks your gums after they heal.
4. You move to maintenance visits, often every three to four months.
5. Implant planning begins once your gums are stable.

Keeping up with visits pays off long after the implant is placed. The Journal of Dental Research reports that people who see a dentist regularly are 60% less likely to lose teeth. The ADA adds that regular dental visits can catch 80% of oral health issues before they become serious.

Do Health Conditions Like Diabetes or Smoking Rule You Out?

Not automatically. Conditions such as diabetes and habits such as smoking can slow healing, so your dentist reviews them carefully, but many people with well-managed conditions still receive implants. Your medical history shapes the plan rather than closing the door.

Mayo Clinic's overview of implant surgery lists health conditions that can affect bone healing, and not smoking, among the signs that implants may be right for you, and it notes that smoking may play a part in implant failure and complications. That's why each person is evaluated individually. A good consultation treats this as a planning question. It's not a judgment about you.

Your dentist may ask about the following, so it helps to have the answers ready.

• How well your diabetes is controlled, if you have it
• Whether you smoke or vape, and whether you're willing to pause around surgery
• Medications that affect bone or bleeding
• Past radiation to the head or neck
• Heart or immune conditions that may call for your physician's input

Be completely honest here. Leaving something out doesn't protect your chances, and it can affect your healing.

Is There an Age Limit for Dental Implants?

Dental implants have a minimum age but no real upper limit. Placement waits until the jaw has finished growing, usually in the late teens, while older adults can receive implants if their health and bone allow it. Overall health matters far more than the number on your birthday.

Younger patients who lose a tooth usually wear a temporary replacement until growth is complete. For adults of any age, the questions are the same ones we've covered: gums, bone, health, and habits.

What changes with age is mostly healing speed and the length of your medication list, not eligibility itself. A person in their seventies with healthy gums and steady health often heals well. A person in their forties with untreated gum disease may need more preparation first.

Many of our patients are in their sixties, seventies, and beyond. They often come in after years of denture trouble, ready to eat what they like. If that sounds familiar, our senior dental care guide explains what changes in the mouth over time and why those changes make a careful exam more important.

Does Being a Candidate Change Which Type of Implant You Need?

Yes, your bone and the number of missing teeth shape the design. Single implants replace one tooth, implant bridges replace several in a row, and full-arch designs replace an entire arch. Your scan helps decide which approach fits you.

• Single-tooth implant: One post and one crown replace a single missing tooth without touching the teeth beside it.
• Implant bridge: Two implants can support a bridge of three to five crowns, so you don't need one post per tooth.
• Implant-supported denture: A removable denture snaps onto a small number of implants and stays put when you eat.
• All-on-4: Four implants hold a fixed full arch of teeth.

Timing is part of the picture too. Where bone allows, an implant can be placed the same day a tooth is removed. That's a candidacy question as well, since the socket and the bone around it have to be healthy enough to hold the post.

What Happens at an Implant Candidacy Consultation?

A candidacy consultation reviews your medical history, examines your teeth and gums, and takes a 3D scan of your jaw to measure bone. You leave with a clear answer and a written plan. At our Peterborough office, the consultation is free and carries no obligation.

1. History: You share your medical history, medications, and goals.
2. Exam: The dentist checks your gums, remaining teeth, and bite.
3. 3D scan: A CBCT scan measures your bone and maps nerves and sinuses.
4. Plain-language review: You see your images and hear what they mean.
5. Written plan: You receive options, timelines, and costs with insurance estimates applied.

Nervous? You're far from alone. BMC Oral Health (2024) reports that 36% of Americans have dental anxiety, and the Journal of Dental Anesthesia reports that sedation dentistry has helped 75% of fearful patients keep up with regular visits. We offer nitrous oxide and oral sedation, so you can ask about comfort options at your first visit.

What If You're Not a Candidate for Dental Implants Right Now?

Being turned down usually means a step comes first, not that implants are off the table for good. Gum treatment, bone grafting, quitting smoking, or better diabetes control can change your answer. If implants truly aren't an option, bridges and dentures are still reliable ways to restore your smile.

That distinction matters. "Not yet" comes with a plan, and you can work toward it.

• Treat gum disease first: A deep cleaning and maintenance can make implants possible later.
• Rebuild bone with a graft: This restores the height or width a post needs.
• Consider reduced-bone designs: All-on-4 full-arch restoration is designed to work with reduced bone, so some patients who aren't ideal for single implants still qualify.
• Improve health factors: Better control of diabetes or a smoking pause can improve healing.
• Use a proven alternative: Traditional bridges and dentures restore chewing and appearance without surgery.

Some patients start with dentures and add implants later to anchor them. That's a legitimate path, not a consolation prize.

Should You Get a Second Opinion If Another Dentist Said No?

Yes, a second opinion is reasonable, because dentists use different scanning tools, treatment approaches, and levels of comfort with bone grafting. A second look can confirm the first answer or reveal an option that wasn't offered. It costs nothing at our office, and you're under no pressure to switch.

In some cases the second dentist suggests a different order of treatment, such as grafting first. In others, the plan is the same but the timeline or price differs. Either way, you gain clarity before you commit.

Bring whatever you have. Recent X-rays, a written treatment plan, and a list of medications make the visit faster. If it's comparable care, we match the price of your existing quote, so you can compare fairly.

• Recent X-rays or scans, if you have copies
• The other office's written treatment plan and quote
• A list of medications and health conditions
• Your questions, written down

What Should You Do Next?

Book a candidacy consultation, because only an exam and a 3D scan can tell you whether you're a candidate for dental implants. Online checklists and friends' stories can't see your bone. A visit takes out the guesswork and gives you facts you can act on.

We see patients from Peterborough, Jaffrey, Dublin, Hancock, and across the Monadnock region, with early-morning hours from 7 AM Monday through Thursday. Bring your questions to Dr. Muhammad Rahim or Dr. Jasper Ainslie.

If you request a time online, a real person from our team replies the same business day to confirm your visit.

Results may vary. Please consult with your dentist at Peterborough Family Dental for personalized treatment recommendations.
