Dental Implants: The Complete Guide
Key takeaways
- A dental implant is a titanium or ceramic post placed in the jawbone that replaces a tooth root and supports a crown, bridge, or denture.
- Most single-implant treatment runs four to nine months from consultation to final tooth, because bone needs three to six months to bond to the implant.
- Active gum infection, uncontrolled diabetes, ongoing smoking, and an incompletely grown jaw are reasons to delay or reconsider implant surgery.
- Peri-implantitis — inflammation and bone loss around an implant caused by plaque — is the main long-term threat to implant success, and it is preventable with daily cleaning.
- IV sedation delivers medication through a vein so its depth can be adjusted during surgery, and it requires fasting, a health review, and a driver.
A dental implant is a small titanium or ceramic post placed into the jawbone to take the place of a missing tooth root. Once the bone heals around it, the post holds a crown, a bridge, or a full denture, so the replacement tooth is anchored in bone rather than resting on the gums.
Put simply: an implant is a new root, and the tooth you see is built on top of it. That two-part design is why implants feel and function more like natural teeth than most other replacement options, and why they are planned as a surgical procedure rather than a same-visit fix.
We practice in Los Gatos, a town in Santa Clara County at the edge of Silicon Valley, and we see patients from across the South Bay, including Cupertino. This guide covers the whole picture — candidacy, staging, cost, risk, and alternatives — so you can walk into a consultation already knowing what questions matter.
What dental implants are
Implants replace the root of a tooth. The post is placed into the jaw, and over roughly three to six months the bone grows tightly against its surface in a process called osseointegration. That biological bond is what gives an implant its stability. After healing, an abutment connects the post to the final restoration.
The same technology scales. One implant can carry one crown. Two to six implants can carry a bridge or a removable overdenture. And when most or all teeth are failing, a full arch can be rebuilt on a planned set of implants — what is often called full mouth implant reconstruction. That approach replaces an entire upper or lower arch, or both, with a fixed set of teeth supported by implants rather than by gum tissue.
Implants are not one product. They are a category, and the right version depends on how many teeth are missing, how much bone is present, and what your bite is doing.
Where the planning happens
Modern implant placement is planned in three dimensions before any surgery. A cone beam scan shows bone height, bone width, nerve position, and sinus location. Digital scanning captures the shape of your teeth and gums without a tray of impression material. Together, these let us decide implant size and angle in advance instead of during surgery.
Who implants are for
Implants tend to suit people in a few recognizable situations:
- A single tooth was lost to fracture, decay, or injury, and the neighboring teeth are healthy enough that you would rather not grind them down for a bridge.
- A tooth is failing and needs removal, and you want the replacement planned before it comes out.
- You wear a denture that moves, clicks, or limits what you eat.
- Several teeth are failing at once from advanced gum disease or long-term wear, and patch repairs are no longer holding.
- A bridge or root canal treated tooth has reached the end of its service life.
Who they are not for, or not yet
Being honest about exclusions matters more than a list of benefits. Implants are usually postponed or reconsidered when:
- Active gum infection is present. Inflamed tissue and unstable bone must be treated first, or the implant inherits the same problem.
- Smoking continues at a meaningful level. Nicotine narrows blood vessels and measurably raises the rate of implant failure.
- Blood sugar is poorly controlled. Well-managed diabetes is generally compatible with implants; uncontrolled diabetes slows healing.
- The jaw is still growing. In teenagers, an implant stays fixed while surrounding bone continues to change, so we wait for skeletal maturity.
- Certain medications are in use, particularly high-dose bone-modifying drugs given intravenously, or ongoing radiation therapy to the jaws. These require coordination with your physician.
- Daily home care is not realistic. Implants do not decay, but the gum and bone around them can become inflamed and recede if plaque is left undisturbed.
Thin or resorbed bone is a different category. It is a reason to add a step — grafting or a sinus lift — not usually a reason to rule implants out.
How implant treatment works, stage by stage
Here is a timeline you can hold against your own calendar. Individual cases shift, sometimes considerably.
Stage 1: Consultation and imaging
One visit, usually under an hour. We review your medical history and medications, examine the site, and take a cone beam scan and digital scans. We discuss sedation options and what the final tooth will look like. You leave with a written plan and a cost estimate.
Stage 2: Preparation, if needed
Not everyone needs this. It may include extracting a failing tooth, a bone graft to rebuild width or height, or a sinus lift in the upper back jaw. Grafts typically heal for three to six months before the implant goes in. Sometimes the extraction and graft happen in the same appointment.
Stage 3: Implant placement
The surgery itself is commonly 45 to 90 minutes for a single implant. Local anesthetic is used in every case. On top of that you can choose nitrous oxide, oral sedation, or IV sedation. IV sedation delivers medication through a vein so it takes effect quickly and the level can be adjusted throughout the procedure; most patients remember little or nothing of the appointment. We monitor your breathing, heart rate, and oxygen the whole time, and you will need a driver.
Stage 4: Healing
Most people return to desk work within one to three days. Swelling peaks around day two and settles over the following week. Soft foods for the first stretch, then a gradual return to normal. Underneath, bone integration continues for three to six months. In selected cases with enough initial stability, a temporary tooth can be attached the same day.
Stage 5: The final restoration
Once the implant is integrated, we scan again and your crown, bridge, or denture is fabricated and fitted. This usually takes two or three short appointments over a few weeks.
Stage 6: Maintenance
Brushing, cleaning between the teeth, and regular hygiene visits. We check the implant and the bone level around it periodically, often with a low-dose X-ray.
What implants cost
Implant pricing is built from parts: imaging and planning, any grafting, the implant itself, the abutment, the final restoration, and sedation. Full arch reconstruction is priced differently again, because the number of implants and the type of prosthesis drive the total. Dental insurance coverage for implants varies widely between plans, and medical coverage sometimes applies after trauma or disease.
A consultation is where a real number gets attached to your case. We give you an itemized written estimate before anything is scheduled, and we can review payment and financing options with you at that visit.
Risks and tradeoffs
Implants have a strong track record, with long-term survival commonly reported above ninety percent. They are still surgery, and they have genuine downsides.
- Time. Four to nine months from start to finish is normal. If you need a graft, longer. A bridge or denture is faster.
- Failure is possible. An implant can fail to integrate, usually in the first few months. It is generally removed, the site heals, and placement can often be attempted again later.
- Peri-implantitis. Inflammation and bone loss around an implant, driven by plaque, is the main long-term threat. It is preventable but it is real.
- Nerve and sinus proximity. In the lower jaw, the nerve supplying the lip and chin runs near lower molar roots. In the upper back jaw, the sinus sits close. Cone beam imaging is how we map and avoid both; the risk is small but not zero.
- The crown is not permanent. The implant post often lasts decades. The crown or denture on top wears and may need replacement or repair over the years.
- Sedation has its own considerations. IV sedation requires a health review, fasting, and a responsible adult to take you home.
- Aesthetics in the front of the mouth are demanding. Gum contour around a front implant takes careful planning and sometimes extra soft-tissue work.
Alternatives worth considering
Fixed bridge
A bridge spans a gap by crowning the teeth on either side. It is faster and involves no surgery, but it means reshaping two healthy teeth, and the bone under the gap continues to shrink.
Removable partial or full denture
The lowest-cost route and the quickest. Dentures rest on the gums, so they can move, limit some foods, and need periodic relining as the jaw changes shape.
Implant supported dentures
A middle path: a denture that snaps onto two or more implants. Far more stable than a conventional denture, and usually fewer implants than a fixed full arch, so the cost sits between the two.
Saving the natural tooth
If root canal treatment or periodontal therapy can keep your own tooth serving well for years, that is often the better first choice. A tooth with reasonable structure and bone support deserves that conversation before extraction.
Doing nothing
Sometimes reasonable for a back molar with no opposing tooth. More often, neighboring teeth drift, the opposing tooth over-erupts, and bone in the empty area slowly resorbs. Knowing the consequences is what makes it a decision rather than a delay.
How to get started
Bring these to your first appointment:
- A current list of medications, supplements, and allergies
- Your medical history, including diabetes, heart conditions, bone-modifying drugs, or radiation treatment
- Recent X-rays or records from your general dentist, if you have them
- Your dental insurance information
- Questions written down — they are easy to forget once you sit in the chair
Good questions to ask: How many implants does my case need? Do I need a graft or sinus lift, and how much time does that add? Which sedation option fits my health history? What does the estimate include, and what is not in it? What happens if the implant does not integrate?
The first appointment should establish four things: whether you are a candidate, what the staged plan looks like, an itemized cost, and a realistic date range for your final tooth. You should leave with those in writing, and with no obligation to schedule.
Comfort comes first in how we plan every case, and the imaging and technology exist to serve that. If you are weighing implants, a conversation costs you an hour and gives you a plan you can actually evaluate.

Frequently asked questions
How long do dental implants last?
The implant post itself often lasts decades, with long-term survival commonly reported above ninety percent. The crown or denture attached to it is a wearing part and may need repair or replacement over the years. Daily cleaning and regular checkups are the biggest factors in how long an implant serves you.
Am I too old for dental implants?
There is no upper age limit for implants. What matters is your general health, your healing capacity, your medications, and whether you have enough bone or can have it rebuilt. Many implant patients are in their seventies and eighties.
What is full mouth implant reconstruction?
It is the replacement of an entire upper or lower arch of teeth, or both, using a planned set of implants that support a fixed bridge. It is considered when most or all teeth in an arch are failing and individual repairs no longer hold. The number of implants depends on your bone and your bite.
Do I need sedation for implant surgery?
No. Local anesthetic alone is sufficient for many single-implant placements. Nitrous oxide, oral sedation, and IV sedation are added when a patient is anxious, when the procedure is longer, or when several sites are treated at once. We review your health history to decide which option is appropriate.
What happens if I do not have enough bone for an implant?
Insufficient bone is usually a reason to add a step, not to rule implants out. A bone graft can rebuild width or height, and a sinus lift creates room in the upper back jaw. Grafts typically heal for three to six months before the implant is placed.
Will my insurance cover dental implants?
Coverage varies a great deal between plans; some dental policies contribute to part of the treatment and others exclude implants entirely. Medical insurance sometimes applies when tooth loss follows an injury or disease. We review your benefits and give you an itemized written estimate before treatment is scheduled.
