BSL, Interpreters, and Complex Information

British Sign Language is central to many Deaf people's identity and how they communicate. Learning a few BSL signs can help with greeting and building rapport, but it does not make a dental team clinically fluent. For consent, discussion of risks and treatment options, safeguarding, medical history, sedation, referral decisions or complex complaints, you should arrange a qualified interpreter or another appropriate form of communication support.

Basic BSL can show respect, but it must not be used to handle a serious clinical discussion. Dental nurses should recognise when "we managed with gestures last time" is no longer adequate. If the patient needs to understand a decision, question risks, or give consent, communication must be accurate and fair.

When to think about formal support

• Consent for treatment, sedation, referral, or extraction.
• Explaining risks, benefits, alternatives, costs, or uncertainty.
• Safeguarding, complaints, capacity, or confidentiality concerns.
• Complex medical history, medicines, allergies, or post-operative risks.
• When the patient asks for an interpreter or cannot access the discussion without one.

Family members may offer social support, but they should not normally act as the interpreter for complex clinical information. Using a family member risks privacy breaches, inaccurate translation and pressure on the patient.

What your practice should have in place for interpreters

Basic BSL can build welcome and rapport, but it is not a substitute for qualified interpreting when a patient must understand complex information or give valid consent.
