What are dental implants?
A dental implant is used to support one or more false teeth. It is a titanium screw that can replace the root of a tooth when it fails. Just like a tooth root, it is placed into the jawbone.
Are implants safe and how long will they last?
Implants are a safe, well-established, tried-and-tested treatment. It’s probably true to say that implants, much like natural teeth, will last for as long as you care for them.
How well you look after your implants – and whether you go for your regular maintenance appointments – will have the biggest impact on how long they will last.
If you don’t look after your implants they will develop a coating similar to that found on neglected natural teeth. Left untreated, this can lead to gum infection, bleeding, soreness and general discomfort. You could get all these problems with natural teeth.
If your implants are well looked after, and if the bone they are fitted to is strong and healthy, you can expect them to last for many years. However, just as with other surgical implants (such as a hip replacement) there is no lifetime guarantee.
I have some of my own teeth. Can I still have implants?
Yes. You can have any number of teeth replaced with implants – from one single tooth to a complete set.
Can implants always be used to replace missing teeth?
It depends on the condition of the bone in your jaw. Your dentist will arrange for a number of special tests to find out the amount of bone still there. If there is not enough, or if it isn’t healthy enough, it may not be possible to place implants without grafting bone into the area first.
Do implants hurt?
Placing an implant is often easier than taking a tooth out and is usually done using a simple local anaesthetic. You will not feel any pain at the time, but just like after an extraction, you may feel some discomfort during the week after the surgery.
Sometimes your dentist might give you a sedative if you are very nervous or if the case is a complicated one. General anaesthetics are rarely used for implants and are generally only used for very complicated cases.
How long does treatment take?
Your dentist will be able to give you a rough timetable before the treatment starts.
Usually the permanent false teeth are fitted 3 to 4 months after the implants are put in. Some teeth can now even be fitted at the same time as the implants (these are called ‘immediate implants’) but you should check with your dentist to see whether these are suitable for you. Sometimes treatment takes longer and your dentist will be able to talk to you about your treatment time.
What about aftercare?
Your dentist will give you instructions on how to look after your implant. They may give you some painkillers after the surgery – or check whether you have them at home – to take over the next few days if you need them.
What happens next?
After your implants have been placed, the bone in your jaw needs to grow onto them and fuse to them. This usually takes a few months. Sometimes the implants may be stable enough when they are fitted for the false teeth to be attached sooner than this.
If you are having one, two or three teeth replaced, you may have a temporary denturein the meantime. If you have full dentures, you can keep wearing these while your implants are healing. Your dentures will need altering, to fit properly after the surgery, and a ‘healing cap’ will usually be placed onto the implant site to protect it.
Are the implant teeth difficult to clean?
No. But aftercare is important if you are going to have a long-lasting, successful implant. Your dentist should give you detailed advice on how to look after your implants. Cleaning around the teeth attached to the implants is no more difficult than cleaning natural teeth. However, there may be areas that are difficult to reach and you’ll be shown methods to help you. You may need to visit your hygienist more often but your dentist will be able to talk to you about this.
If I had gum disease when I had my own teeth, will I get it with the teeth attached to the implants?
Yes, if you don’t care for them well enough. If you keep them clean and have them regularly checked by your dentist you should not have any problems. Smoking also affects the health of natural teeth and implants. So, if you smoke, you may need to look after your implants more carefully.
Can I take the teeth out if they are fixed to implants?
Most teeth attached to implants can only be fitted and removed by the dentist. However, if you have removable dentures attached to the implants, then you’ll be able to take them out for cleaning.
Do the implants show?
Most implants look exactly like natural teeth.
Do I have an implant for each missing tooth?
If you have a single tooth missing, you will need an implant to support it. If you have a number of teeth missing, and these are next to each other, you could still have one implant for each tooth. Or you may find that two or more implants may be able to support more than one tooth each. Your dentist will talk to you about the best option for you.
What if I have an accident?
Implants and the teeth they support can be damaged by an accident in the same way that natural teeth can. So it is important that you wear a professionally mademouthguard if you play sports that involve contact or moving objects. If just the teeth are damaged, they can usually be removed from the implant and replaced.
However, if the titanium implant itself is damaged beyond repair, it can be safely left in the jaw if it is too difficult to remove. Another implant may be fitted alongside it to replace the damaged one.
What happens if the implant does not fuse with the bone?
This happens very rarely. If the implant becomes loose during the healing period, or just after, it is easily removed and your jaw will heal in the normal way. Once your jaw has healed, another implant can be placed there. Or the dentist can make a bridge, fitting it to the implanted false teeth that have ‘taken’.
Can I get the treatment on the NHS?
Implants are not normally available on the NHS. Implants are available privately. However, in many situations, the cost of the treatment is only a little more than the cost of more conventional private dental treatment with crowns and bridges. Over the longer term, implants are usually a more cost-effective and satisfactory option.
There are other advantages to implants, too. If you have an implant to replace a single tooth, there is no need to cut down the teeth either side of it. If you had a bridge, your dentist would need to do this and fit crowns to these teeth to support the bridge.
Normal dentures often mean you can’t eat or speak well, because the dentures move about. But teeth attached to an implant don’t cause this problem as they are anchored to the bone more firmly than natural teeth.
Where do I get this treatment?
Talk to your dentist, so they can refer you to an experienced ‘implantologist’ for assessment and treatment. Your dentist may already carry out some or all of this type of treatment and will give you the advice you need.
Remember to ask:
- exactly what treatment is proposed
- what experience the dentist has in this work
- the total cost of the treatment; and
- what the alternatives are
Make sure you get a treatment plan, along with an estimate, and ask if a guarantee is included for your treatment.
If you are unhappy with any of the answers you get, then do ask for a second opinion. You will be spending a lot of time, effort and money, so you must be sure that you know what you are getting at the end of the treatment.
