If you have lost a tooth, or several, an implant is the closest thing modern dentistry has to growing a new root. A small screw-shaped post is placed in the jawbone, the bone gradually bonds to it, and a crown, bridge or denture is attached on top. Carefully planned and properly looked after, the result looks, feels and works much like a natural tooth. This page explains who implants suit, how treatment usually unfolds, what recovery involves and how implants compare with other ways of replacing missing teeth, so you can arrive at your consultation with a clear picture.
Is it right for you?
Implants can replace a single tooth, several teeth in a row, or support a full set of teeth. Many adults are suitable, and age on its own is rarely the deciding factor. What matters more is your general health, the condition of your gums and the amount of bone where the tooth used to be.
Implants are often a good option if you:
- have one or more missing teeth and want a fixed replacement rather than something removable
- would prefer not to have healthy neighbouring teeth filed down to support a bridge
- find a partial or full denture loose, uncomfortable or hard to eat with
- have healthy gums, or gum disease that has been treated and is under control
- are willing to keep up good daily cleaning and regular check-ups
Some situations call for extra care or a different plan. Smoking slows healing and raises the risk of problems around implants, so your dentist will usually encourage you to cut down or stop. Conditions such as poorly controlled diabetes, a history of radiotherapy to the head and neck, or certain medicines that affect bone may change what is advisable, which is why an honest and complete medical history matters. Implants are also generally not placed until the jaw has finished growing, so they are not usually an option for younger teenagers.
If bone has shrunk since the tooth was lost, that does not automatically rule implants out. A bone graft, or in the upper back jaw a sinus lift, can often rebuild the area first, although this adds time to treatment. A 3D scan is the best way to find out what you are working with.
How an implant works
A dental implant is not one piece but a small system with three parts, each with its own job.
The implant
This is the root replacement: a small screw-shaped post, usually made of titanium or a titanium alloy, and sometimes of zirconia ceramic. It sits inside the jawbone. Over the following months, bone cells grow tightly against its surface in a process called osseointegration. That bond is what allows the implant to take chewing forces the way a natural root does.
The abutment
The abutment is a connector that sits on top of the implant at gum level. It links the part hidden in the bone with the visible tooth above, and it is shaped so the gum can settle neatly around it.
The restoration
On top sits what you actually see: a crown for a single tooth, a bridge spanning several missing teeth, or a full-arch bridge or denture held by several implants. Crowns are commonly made from ceramic materials such as zirconia or porcelain, shaded to match your other teeth.
Because an implant is anchored in bone, it also loads that bone when you chew. This can help slow the gradual shrinking of the jaw that tends to follow tooth loss, something that bridges and removable dentures do not do.
Your treatment step by step
Every plan is tailored to the person, but most implant treatment follows the same broad stages.

Step 1
Consultation and 3D scan
Your dentist examines your mouth, goes through your medical history and takes images, typically including a 3D scan of the jaw. This shows the height and width of the bone and the position of nerves and sinuses, so the implant can be planned precisely. You should come away knowing whether you need any preparatory treatment, such as an extraction, gum treatment or bone grafting, and roughly what the timeline looks like.

Step 2
Placing the implant
The implant is placed under local anaesthetic, so the area is numb, and sedation may be offered if you feel anxious. The dentist opens the gum, prepares a precise channel in the bone and positions the implant. For a single implant, the procedure itself often takes around an hour, though this depends on the case. In some situations a tooth can be removed and an implant placed in the same appointment. Afterwards the gum is closed, sometimes with a small healing cap left visible above it.

Step 3
Healing and integration
Next comes the most important phase, and the one you cannot rush: the bone bonding to the implant. This commonly takes anywhere from a few weeks to several months, often around three to six months, depending on the bone quality, the location in the mouth and whether grafting was done. During this time you may wear a temporary tooth so you are not left with a visible gap. In carefully selected cases a temporary crown can be attached to the implant soon after placement, but your dentist will only suggest this if the implant is stable enough.

Step 4
Your final crown
Once the implant has integrated, impressions or a digital scan are taken and the final crown is made to fit your bite and match your smile. It is then fixed onto the abutment, either cemented or held by a small screw. Your dentist checks how your teeth meet and makes fine adjustments so the new tooth feels natural when you chew.
One trip or two?
If you are travelling for treatment, timing matters. Because the implant needs to heal before the final crown goes on, implant treatment usually involves two visits. On the first trip the implant is placed, along with any grafting or extractions that are needed. You then return home to heal, often for a few months, before coming back for the final crown.
Each visit can often be planned to last several days, so there is time for check-ups before you fly. Your dentist will tell you how long to allow and whether there are any restrictions on flying after surgery. Sharing your X-rays or a recent scan in advance helps the clinic plan the first trip properly and make the best use of your time.
Recovery and aftercare
Many people find recovery after a single implant more manageable than they expected, often comparable to having a tooth taken out. Some swelling, mild bruising and tenderness for a few days is normal, and is usually controlled with over-the-counter pain relief and cold packs. More extensive surgery, such as several implants or grafting, can mean a longer recovery.
In the first days and weeks it helps to:
- eat soft, lukewarm foods and chew on the other side
- avoid smoking and alcohol, which can slow healing
- keep the area clean with gentle brushing and any mouth rinse you are given
- avoid strenuous exercise for the first day or two
- take any prescribed medicines exactly as instructed
- contact your dentist promptly if pain, swelling or bleeding gets worse rather than better
Stitches, if used, are either dissolvable or removed after about one to two weeks. Your dentist will give you written aftercare instructions that are specific to your treatment.
How long implants last and how to look after them
An implant that has bonded well with healthy bone can last for many years, and for many people a lifetime. The crown on top is subject to normal wear and may need replacing at some point, just as a crown on a natural tooth would. How long your implant lasts depends a great deal on how well it is cared for and on your general health.
The main threat is peri-implantitis, an inflammation of the gum and bone around an implant, similar to gum disease around natural teeth. It is largely preventable with good habits:
- brush twice a day with a soft brush, paying attention to where the crown meets the gum
- clean between your teeth daily with interdental brushes, floss or a water flosser
- keep up regular check-ups and professional cleanings
- do not smoke
- if you grind your teeth, ask whether a night guard would help protect the crown
An implant cannot decay, but the gum and bone around it still need attention. If your gums bleed or the implant ever feels loose, see a dentist rather than waiting for your next routine visit.
Alternatives to consider
An implant is not the only way to replace a missing tooth, and a good dentist will talk through the options with you openly.
Dental bridge
A conventional bridge attaches a false tooth to crowns on the teeth either side of the gap. It is quicker, needs no surgery and can be a sensible choice if those neighbouring teeth already need crowns. The downside is that healthy tooth structure is removed, and the bone under the missing tooth is not stimulated.
Removable denture
A partial or full denture is the least invasive option and can replace many teeth at once. Some people manage well with dentures; others find them loose or uncomfortable and notice they affect taste or speech. Dentures can also be held more firmly by a few implants, a middle ground that is worth asking about.
Full-arch solutions
If most or all of the teeth in a jaw are missing or failing, placing one implant per tooth is rarely necessary. A full arch of fixed teeth on four or six implants, known as All-on-4 or All-on-6, may be a better fit.
Leaving the gap
Leaving a gap is an option too, but neighbouring teeth can drift, the opposing tooth can over-erupt, and the bone in the area tends to shrink over time, which can make later treatment more complicated.
Your personal assessment
The only way to know whether implants are right for you is a proper assessment of your mouth, your bone and your health. If you are considering treatment, you are welcome to send us recent photos of your teeth and any X-rays or scans you already have. Our team will review them and give you an honest view of the options that may suit you and what the next steps would be.
