Losing a tooth, whether through decay, injury or extraction, leaves a gap that most people want to fill. Beyond appearance, a gap can affect chewing, let neighbouring teeth drift out of position, and change the way you bite over time. The two most common ways to replace a single tooth are a dental implant or a dental bridge. Both can work well, but they involve different procedures, different demands on the surrounding teeth, and different long-term considerations. This article explains the basic differences so you have a clearer idea of the questions to ask when you see a dentist.
A conventional bridge replaces the missing tooth using the teeth either side of the gap as support. Those two teeth are shaped down and fitted with crowns, and a false tooth sits between them, all joined as one fixed piece. It is cemented in place and not removable by the patient. Bridges are made in the same way as the restorations used on our crowns and veneers page, since a bridge is essentially two crowns with a false tooth attached.
The main drawback is that healthy teeth either side of the gap need to be reduced to take the crowns, even if they have no decay or damage. If one of those teeth later needs root canal treatment or develops a problem, the whole bridge can be affected. On the plus side, a bridge does not involve surgery, treatment can usually be completed over a couple of visits, and it avoids the healing time needed for an implant.
An implant is a small titanium post placed into the jawbone to act as an artificial root. Once it has had time to integrate with the bone, a crown is fitted on top to recreate the visible part of the tooth. Because the implant stands alone, the teeth either side are left untouched. You can read more about the procedure on our dental implants page.
Implants generally need enough healthy bone at the site, and adequate healing time between placement and fitting the crown. Gum disease, smoking, and certain medical conditions can affect whether an implant is suitable or how predictably it heals, which is why an assessment is needed before anyone can say whether this option is right for a particular gap.
There is no single correct answer for everyone, and it genuinely depends on your individual circumstances. Relevant factors include the condition of the teeth next to the gap, how much bone is present where the tooth was lost, your general health, whether you smoke, and your own priorities, for example whether you would rather avoid surgery or avoid any risk to adjacent teeth. Cost and whether treatment is available on the NHS or privately also plays into the decision for many patients, since implants are not routinely provided on the NHS except in specific clinical circumstances, whereas a bridge may be available on the NHS depending on need. A dentist can examine the gap, take any necessary x-rays, and talk through which option is realistic in your case. Please do not take this article as advice on what is right for your own tooth; it is intended as background only.
If you have recently lost a tooth, it is worth being seen reasonably promptly. The longer a gap is left, the more likely neighbouring teeth are to tilt into the space and the opposing tooth to over-erupt, which can make later replacement more complicated. That said, there is rarely an emergency about choosing a replacement, and it is reasonable to take time to understand your options, ask questions, and think about cost before committing. If the gap is not causing pain, is not visible when you smile, and your bite feels comfortable, it is generally fine to book a routine consultation rather than treating it as urgent. If you notice pain, swelling, a loose neighbouring tooth, or a change in your bite, it is sensible to be seen sooner rather than waiting.
If you are trying to decide between an implant and a bridge, the most useful next step is an examination so that a dentist can look at the specific gap, the surrounding teeth, and the bone underneath. Enhance Dental, Cosmetic and Training Centre, at 26 High Street, High Wycombe, sees both NHS and private patients and is open Monday to Friday, 9am to 5pm. You can call 01494 524455 to arrange an appointment and discuss which option fits your situation.
Neither option is automatically better; they suit different situations. An implant avoids altering the neighbouring teeth but needs adequate bone and a period of healing, while a bridge is quicker and non-surgical but relies on the adjacent teeth for support. A dentist can tell you which is realistic for your particular gap.
A single gap can still cause changes over time, such as neighbouring teeth drifting or the opposing tooth over-erupting, even if chewing feels fine now. It is not usually an emergency, but it is worth having it assessed rather than leaving it indefinitely.
Smoking and gum disease can affect how predictably an implant heals and integrates, so these are things a dentist will need to assess before recommending implant treatment. In some cases treating gum disease first, or stopping smoking, may improve the chances of a good result.
A bridge is generally completed over a shorter number of visits since it does not require bone healing. An implant takes longer overall because time is needed between placing the implant and fitting the final crown, though exact timescales vary between patients and cannot be guaranteed in advance.
