Composite Bonding: Five Common Pitfalls for UK Dentists
Composite bonding has become one of the most visible treatments in UK dentistry. Driven by social media, increased demand for cosmetic treatment and its reputation as a relatively straightforward and minimally invasive way of improving a smile, its popularity has grown rapidly.
With that growth, however, comes increasing dento-legal risk. In April 2026, the General Dental Council (GDC) specifically highlighted the “bonding boom”, noting that composite bonding had become one of the most frequent types of case encountered by one of its clinical advisers during Fitness to Practise investigations over the preceding three years.

1. Treating the aesthetic complaint without adequately diagnosing the problem
Composite bonding may appear straightforward, but aesthetic treatment still requires appropriate assessment and diagnosis.
The cause of tooth wear, discolouration, spacing or an altered tooth position should be considered before treatment starts. Occlusion, parafunction, periodontal health, active disease and the patient’s expectations can all affect whether bonding is appropriate.
The GDC’s recent blog post regarding composite bonding cases specifically identified shortcomings in diagnosis, treatment planning and consent among recurring concerns.
The
key message is simple: cosmetic treatment does not require a lower standard of
clinical assessment.
2. Understanding the consent discussion
A signed consent form is not, by itself, evidence of valid consent.
The GDC requires dentists to explain relevant treatment options, risks, potential benefits, likely prognosis and costs, and to check that the patient has understood the information provided. Consent should also remain valid throughout the course of treatment.
For composite bonding, this should include realistic discussion of maintenance and limitations. Patients may need to understand the potential for staining, chipping, loss of surface lustre, repair or replacement, changes to speech or the sensation of tooth bulk, and the possibility that future adjustment may be necessary. These are all issues highlighted by the GDC in its 2026 blog post.
Importantly, describing bonding as completely “reversible” may itself be problematic. Complete composite removal without alteration of the underlying enamel can be difficult.
3. Allowing social media to set the patient's expectations
Before-and-after
photographs can be powerful marketing tools, but they can also create
unrealistic expectations.
GDC advertising guidance requires promotional material to be accurate and not misleading and specifically warns against claims likely to create unjustified expectations about treatment outcomes. Social-media advertising should also make clear that treatment is subject to appropriate clinical assessment.
Dentists should be particularly cautious about language suggesting a guaranteed “perfect smile” or implying that bonding is suitable for everyone.
4. Weak clinical records
When a patient is dissatisfied, the quality of the contemporaneous record may become crucial.
The GDC requires complete and accurate records and recommends documenting consent discussions in detail. A generic template stating “risks discussed” may provide considerably less protection than a personalised record showing the patient’s concerns, options discussed, relevant risks, expectations and understanding.
5. Using patient photographs without appropriate consent
Composite bonding lends itself naturally to photography and social media, but clinical consent and marketing consent are separate matters.
It is essential dentists wishing to use patient photographs for promotional purposes explain how the images will be used, ensure the patient understands, obtain and record consent, and explain that permission can subsequently be withdrawn.
TDS Top Five Tips
1. Assess before you bond – record diagnosis, occlusion, relevant disease and why treatment is appropriate.
2. Manage expectations before treatment – particularly longevity, maintenance and aesthetic limitations.
3. Remember that consent is a conversation – a signed form alone is not enough.
4. Keep individualised records – document what this patient was told and understood.
5. Audit your social media – ensure claims, photographs and before-and-after images comply with GDC advertising guidance.
In conclusion, composite bonding can provide excellent, conservative aesthetic outcomes. However it must not be viewed as a panacea for aesthetic cases and should not lead to cutting corners in assessment, consent, diagnosis or documentation. With demand continuing to grow, careful expectation management and robust records remain some of the best protections for both dentist and patient.
