Three ways to replace missing teeth

Missing teeth can affect more than your smile. Chewing, speaking, and the health of your remaining teeth and gums all come into play. Your dentist may suggest dental implants, a traditional bridge, or a denture. Each option has its own strengths, and understanding the differences helps you make a confident choice with your dental team.

A dental implant is a titanium post placed into the jawbone. It acts like a tooth root, and after a healing period, it supports a crown. A traditional bridge uses the teeth on either side of the gap as anchors for a false tooth. A denture is a removable plate that sits on the gums, replacing several or all teeth. Sometimes an implant can support a denture for extra stability, but here we focus on the three main standalone options.

Longevity: how long do they last?

With good care, dental implants can last 15 to 25 years or more. Some people keep them for life. The crown on top may need replacing after 10 to 15 years due to wear. Traditional bridges typically last 10 to 15 years, but they often need replacing sooner if the supporting teeth develop decay or gum disease. Dentures usually last 5 to 8 years before the fit changes as your jawbone shrinks.

Bone loss is a key factor. Implants stimulate the jawbone, which helps preserve it. Bridges and dentures do not, so the bone underneath can gradually recede. This is why dentures may become loose over time and need relining or remaking. Implants have a success rate of around 95% over ten years in healthy non-smokers, which is a strong record.

Comfort and everyday function

Most people find implants feel the most like natural teeth. There is no movement when you bite or speak. You can eat apples, crusty bread, and steak without worry. A bridge is fixed, so it also feels stable, but it can trap food underneath, which is uncomfortable and a decay risk. Dentures can rub, slip, and click. They may reduce your ability to taste food because the plate covers the palate. Lower dentures are often the hardest to tolerate.

• Implants: no wobble, no covering of the palate, natural chewing force.
• Bridges: fixed and stable, but cleaning underneath is fiddly.
• Dentures: removable, can be uncomfortable, may affect speech initially.

Maintenance and oral hygiene

All three need careful cleaning, but the routines differ. Implants are cleaned like natural teeth: brush twice daily, use interdental brushes or floss around the implant, and attend regular hygienist appointments. Your hygienist can show you how to clean the abutment and crown without damaging the gum. A water flosser can help, but it should not replace manual brushing. Bridges require special floss threaders or superfloss to clean under the false tooth. If you skip this, decay can start in the supporting teeth.

Dentures must be removed at night, brushed with a denture cleaner (not toothpaste, which is abrasive), and soaked. You should also brush your gums, tongue, and any remaining teeth. Poor denture hygiene can lead to fungal infections and gum inflammation. With implants, smoking greatly increases the risk of failure, so your dentist will advise you to quit. Your hygienist can also check for peri-implantitis, a gum condition around implants that is easier to treat when caught early.

Suitability: who is a good candidate?

Implants work best for people with healthy gums and enough bone in the jaw. If bone is thin, a bone graft may be needed first. Uncontrolled diabetes, heavy smoking, and certain medications can affect healing. Age itself is not a barrier, but overall health matters. Bridges suit people who have strong, healthy teeth either side of the gap. If those teeth are already filled or weak, a bridge may not be ideal because it puts extra load on them. Dentures are often the choice when many teeth are missing, when bone loss is severe, or when someone prefers a removable option.

Your dentist will assess your mouth, take X-rays, and discuss your medical history. It is not just about the missing tooth; the health of your whole mouth matters. Your hygienist can also advise on gum health before any treatment starts. If you grind your teeth, that may affect the choice too, as implants and bridges can be damaged by heavy clenching.

Talking it through with your dental team

Cost and NHS availability vary. Implants are usually private, whilst bridges and dentures may be available on the NHS in some cases. Ask about upfront costs, aftercare, and what happens if something goes wrong. Bring your questions to your dentist and hygienist. They can explain the trade-offs for your specific situation. A good conversation now will help you choose a replacement that feels comfortable, functions well, and lasts as long as possible.
