A dental implant is a titanium post placed into the jawbone to take the place of a missing tooth root. Once the bone has grown around it, a crown is attached on top. The result is a replacement tooth that is fixed in place and does not rely on the teeth either side of the gap for support. The process is staged rather than immediate, because the bone needs months to fuse to the post before the final tooth goes on.
This guide covers what an implant actually is, how the stages work, who tends to be suitable, what the risks are, and what needs to happen afterwards. It does not cover fees, and it is not a recommendation to have treatment. Whether an implant is appropriate for a particular gap is a clinical assessment, not something that can be decided from an article.
What is a dental implant?
healthdirect describes a dental implant as a metal screw used in place of the root of a missing tooth. That is the essential idea. Where a bridge or a denture sits on top of the gum and borrows support from elsewhere, an implant replaces the part of the tooth you never see.
An implant restoration has three components:
- The implant post. A titanium fixture placed surgically into the jawbone, taking the role of the tooth root.
- The abutment. A connector attached to the post once healing is complete, which sits at gum level and carries the replacement tooth.
- The crown. The visible tooth, shaped and shaded to sit alongside the natural teeth around it.
Titanium is used because bone will grow directly onto its surface, a process called osseointegration. That biological bond is what allows an implant to carry chewing load. It is also why the timeline cannot be rushed, since the fusion happens at the pace the bone sets.
What does the process actually involve?
Assessment and planning
The first stage is working out whether there is enough bone in the right place, and what else is going on in the mouth. This generally involves imaging to assess bone volume, the position of nerves, and the proximity of the sinus in the upper jaw. Existing gum disease or decay elsewhere is addressed before implant surgery is planned, because the health of the surrounding tissue affects how the implant behaves afterwards.
This stage also establishes whether a bone graft is needed. Where a tooth has been missing for a long time, the bone at that site may have reduced in volume, and grafting may be required before or at the time of placement.
Extraction, where the tooth is still present
If the problematic tooth is still in place, it is removed first. Depending on the site and the condition of the bone, placement may follow immediately or after a healing period.
Placement
The implant post is inserted into the jawbone under local anaesthetic. Smile Creative’s dental implants page notes that a single implant is often inserted within about 30 minutes, while multiple implants may take a few hours. Most people describe the sensation during placement as pressure rather than pain, because the area is anaesthetised.
Healing and osseointegration
This is the long stage and the one people underestimate. The Smile Creative implants page describes the implant taking between three and six months to fuse with the jawbone. During this period the site is left to heal, and a temporary solution may be used where the gap is visible.
Abutment and crown
Once the implant is stable, it is uncovered and the abutment is attached, which acts as the foundation for the new tooth. The crown is then made and fitted. Smile Creative uses CEREC technology for some same day crowns, and a ceramic laboratory technician for others including implant crowns, depending on what the case requires.
What does recovery actually feel like?
People plan around the surgery and underestimate the weeks that follow, so it is worth setting out what is typical.
In the first day or two, some swelling, bruising and discomfort at the site is normal, and is generally managed with simple pain relief. Most people find this settles noticeably by the third or fourth day. Eating on the other side and sticking to softer food for a period is usual, as is avoiding disturbing the site while the gum closes.
After the first week or so, the surgical discomfort has usually resolved and the long quiet phase begins. This is the part that surprises people. For the three to six months of osseointegration there is generally nothing to feel and nothing to do beyond keeping the area clean and attending review appointments. The work is happening in the bone, invisibly, and it cannot be hurried.
Things that should prompt a call rather than a wait: pain that is increasing rather than settling after the first few days, swelling that grows after day two or three, bleeding that does not stop, a bad taste or discharge from the site, numbness that persists, or a fever.
What is bone grafting, and when is it needed?
An implant needs enough bone, in the right shape, to be stable and to sit where the tooth needs to be. Where there is not enough, bone grafting is the process of building up the site so placement becomes possible.
The most common reason it is needed is time. Bone at the site of a missing tooth is no longer loaded by a root, and it tends to reduce in volume over the months and years afterwards. Someone who lost a tooth recently may have enough bone. Someone who lost the same tooth fifteen years ago often does not. Other reasons include bone lost to gum disease, bone lost in the trauma that removed the tooth, and, in the upper jaw, the position of the sinus sitting lower than the implant needs.
Grafting adds time to the overall plan and adds a stage, sometimes carried out at the same appointment as placement and sometimes months before it. What is appropriate depends on how much is needed and where, and it is assessed with imaging rather than estimated.
The practical takeaway is that a gap is generally more straightforward to restore sooner than later, which is worth knowing even if you are not ready to decide.
Can one implant replace more than one tooth?
Not on its own, but implants do not have to be placed one per missing tooth.
- A single implant carries a single crown, which is the most common arrangement for one gap.
- Two implants can carry a bridge spanning three or more teeth, so a larger gap does not always mean an implant per tooth.
- A small number of implants can retain or support a denture, so that it clips into place rather than resting on the gum. This is often discussed where someone has struggled with a conventional lower denture.
- A full arch can be restored on a number of implants, with the number determined by the anatomy and the plan rather than by the number of teeth being replaced.
Which arrangement suits depends on the pattern of missing teeth, the bone available across the arch, and what the person wants day to day. Our comparison of implants, bridges and dentures covers how these sit against the alternatives.
Who tends to be suitable for an implant?
Suitability is assessed individually, but the factors a dentist weighs are reasonably consistent.
- Sufficient bone volume and density at the site, or a plan to build it with a graft
- Healthy gums, with any active gum disease treated first
- General health that supports healing and allows a minor surgical procedure
- A jaw that has finished growing, which matters for younger patients
- A willingness to maintain the implant, since long term cleaning around it is part of the treatment rather than optional
- No untreated decay or infection elsewhere in the mouth
Several things complicate implant treatment without automatically ruling it out. Smoking, uncontrolled diabetes, a history of gum disease, grinding, and some medications all affect healing or the risk profile, and they are discussed and managed rather than treated as an automatic no. That conversation is part of the assessment.
What are the risks?
Implant placement is a surgical procedure and it carries real risks, which should be discussed before you consent rather than discovered afterwards. Known complications include infection at the site, failure of the implant to fuse with the bone, injury to nearby nerves, and, in the upper jaw, involvement of the sinus. Peri-implantitis, which is inflammation and bone loss around an implant driven by bacteria, can develop later and is the main long term risk.
Some discomfort and swelling after placement is normal and generally settles over a few days. Pain that is worsening rather than improving, ongoing bleeding, or swelling that increases after the first couple of days should be reported to the practice.
The point of listing these is not to discourage anyone. It is that a considered decision requires knowing what can go wrong, and an article that presents implants as risk free would not be giving you what you need to decide.
What happens if a missing tooth is left alone?
This is a fair question, and the answer is that it depends on the tooth and on the individual, which is why it is a clinical discussion rather than a rule.
Broadly, the bone at the site of a missing tooth is no longer loaded by a root, and bone that is not loaded tends to reduce in volume over time. Teeth either side of a gap can drift, and the opposing tooth in the other jaw can over erupt into the space. Chewing tends to shift towards the other side. How much any of this matters depends on which tooth is missing, how long it has been missing, and what the rest of the mouth is doing.
Some gaps are monitored rather than restored, particularly at the back of the mouth. That is a legitimate option and worth asking about.
How do you look after an implant?
An implant crown does not decay, because it is not natural tooth. The gum and bone around it are entirely capable of becoming diseased, and that is what determines how the implant performs over time.
- Clean around the implant daily, including between it and the adjacent teeth. The specific tool depends on the shape of the space and should be demonstrated rather than guessed at.
- Keep to the professional cleaning and review interval your dentist sets. Implant patients are often reviewed more frequently than the general recall interval.
- Report any bleeding, tenderness, or a sensation of looseness around the implant promptly. Bone loss around an implant is usually painless in its early stages.
- Manage grinding if it applies to you, since load matters.
- Smoking affects both healing and long term outcomes, and this is worth raising honestly at the planning stage.
The daily care principles are much the same as for natural teeth, which are covered in our guide to adult oral health.
Implants and the rest of your dental health
Implants are usually discussed as a standalone treatment, but they sit inside the wider picture. Active gum disease is treated before placement because the same bacterial process that damages bone around teeth can damage bone around an implant. Decay elsewhere is addressed for the same reason. If grinding has contributed to losing the tooth in the first place, that gets managed as part of the plan rather than left for later.
Whether a gap needs replacing at all, and with what, is part of a broader treatment conversation. Our article comparing implants, bridges and dentures covers the options side by side, and the differences between general and cosmetic dentistry explains how restorative work sits between the two.
Questions worth asking at your consultation
- “Is there enough bone at this site, or would grafting be needed?”
- “What is the expected timeline from placement to final crown for my case?”
- “What are the specific risks for my situation, given my medical history?”
- “What are the alternatives to an implant here, including doing nothing?”
- “What will I need to do to maintain it, and how often will you want to review it?”
- “What happens if it does not integrate?”
