Cantilever Bridges: When a Bridge Is Supported From One Side

A cantilever bridge is a type of fixed dental bridge that replaces one missing tooth using support from only one side of the gap, rather than from teeth on both sides as with a traditional bridge. The replacement tooth, called a pontic, is joined to one or two crowned supporting teeth next to it, and the whole structure is cemented in place so it is not removed by the patient.

A cantilever design is one of several ways to build a fixed bridge, alongside the traditional two-sided design and the Maryland resin-bonded design. It tends to be considered for a specific situation: a gap that has a natural tooth on only one side, so there is nothing on the far side to anchor a traditional bridge to.

This page explains when a cantilever bridge is considered, how the one-sided support affects the supporting tooth, and how it compares with our other bridge designs. For an overview of every bridge type we offer, see our dental bridges page.

Support: one or two prepared teeth on a single side of the gap, rather than teeth on both sides.

Suited to: a gap with a supporting tooth on only one side, most often in the front of the mouth or in a lower-load area at the back.

Materials: zirconia or porcelain fused to metal for the pontic and supporting crowns; E-max is generally reserved for short front-tooth spans.

Anaesthesia: preparing the supporting tooth or teeth is carried out under local anaesthesia, in the same way as for a traditional bridge.

A cantilever bridge is considered when a patient is missing a single tooth and a natural tooth is present on only one side of that gap, so a traditional bridge, which needs support on both sides, is not straightforward to fit. This situation can arise at the very end of the row of teeth, or where the tooth on the far side of a gap has already been lost or is not suitable to prepare for a crown. Our missing teeth page covers the wider causes of tooth loss and the full range of replacement options, including implants, dentures and other bridge designs; this page focuses on the cantilever bridge design itself.

A cantilever bridge is generally avoided at the back of the mouth, where chewing forces are highest and the leverage on a single supporting tooth is greatest, unless the supporting tooth and bone are assessed as strong enough. Patients whose only available supporting tooth already has a weakened root, active gum disease, or insufficient bone support are usually advised towards a different option, such as a traditional bridge with support restored on the far side, a dental implant, or a removable partial denture. Where more than one tooth is missing in the same area, a longer span is also usually better supported by an implant or a different bridge design rather than a single-sided cantilever.

Before you travel. The process starts with a free online consultation. You send recent photos and, if you have them, X-rays, and our dentists give an initial view on whether a cantilever bridge suits your gap before you book anything.

At the clinic. A clinical examination and X-rays confirm the root, bone and gum condition of the tooth or teeth that would support the bridge, and whether the biting load on that side is likely to be manageable.

If cantilever is not the right fit. Where the assessment favours a different design, your dentist discusses a traditional bridge, a Maryland bridge, or a dental implant instead, with the reasons explained before treatment begins.

Fitting a cantilever bridge follows the same broad sequence as a traditional bridge. The supporting tooth or teeth are reshaped under local anaesthesia, known as preparation, to make room for the crown that will anchor the bridge, and a digital scan or a physical impression is taken of the prepared tooth and the surrounding teeth. A temporary bridge protects the area while the definitive bridge, made from zirconia or porcelain fused to metal, is produced in a dental laboratory, and it is then tried in, checked for fit and bite, and cemented into place.

Which design suits a particular gap depends mainly on whether a natural tooth is present on both sides of it. The simplified illustration below shows how this one factor points towards a cantilever bridge, a different bridge design, or a dental implant; your dentist confirms the right option from your own X-rays.

With a well-fitted cantilever bridge, chewing function is restored in the treated area and the pontic is shaded to blend with the surrounding teeth, so it is not obvious in everyday conversation or a smile. Because the bridge is fixed rather than removable, it is cared for in the same way as your natural teeth, with particular attention to cleaning underneath the pontic. Many bridges last for years with good care; how long any individual cantilever bridge lasts depends on the strength of the supporting tooth, your bite, whether you grind your teeth, and how well you keep up cleaning underneath it.

Load falls on one side only. Because the pontic has no support on the far side, the full biting load on that tooth is carried by the supporting tooth or teeth on one side, which is the main reason case selection matters so much.

Generally limited to a single tooth. A cantilever design is usually reserved for replacing one missing tooth rather than a longer run of teeth, since a wider pontic increases the leverage on the supporting side.

Tooth reduction cannot be undone. Preparing the supporting tooth or teeth for their crowns removes a layer of natural tooth structure, and this cannot be reversed once done.

Your dentist explains the risks that apply to your specific case, based on your X-rays and bite, before you give your consent.

Cantilever bridge treatment at Er Dental Clinic is assessed and planned by Dt. Vijdan Aslanoğlu, alongside our other dentists. Whether a cantilever bridge, a traditional bridge, a Maryland bridge or a dental implant suits your gap is confirmed individually from your X-rays and a review of the supporting tooth, and your written treatment plan states which design is proposed and why. You can read more about the dentists who assess bridge treatment on our dentists page.

If a natural tooth is present on both sides of the gap, a traditional bridge is generally the more established option, since the load is shared between two supporting teeth rather than carried by one side. Where the gap is at the front of the mouth and only minimal preparation of the neighbouring teeth is wanted, a Maryland bridge may be considered instead of preparing a tooth for a full crown. A dental implant is a further alternative where a cantilever bridge is not suitable or not preferred, replacing the missing tooth with its own root rather than relying on a neighbouring tooth for support.

A cantilever bridge is one of several fixed bridge designs offered at Er Dental Clinic. The pages below cover the other options and the wider picture of tooth replacement.

Most patients go back to normal eating and speaking within a day or two of the temporary bridge being fitted, and there is usually no need to take time off work or daily activities during either visit. Some mild sensitivity around the supporting tooth is common in the first few days and settles on its own or with an ordinary painkiller if needed. Once the definitive cantilever bridge is cemented in place, it is treated like a natural tooth for eating, and your dentist explains when it is safe to fly home.
