NHS dental terms — a plain-English glossary
Seven NHS dental terms every UK practice manager, receptionist, and AI-trained call agent has to get right — defined in plain English, with the regulatory references that matter and a short note on how an AI receptionist should handle each on a live call. Written for UK practices in 2026.

UDA (Units of Dental Activity)
UDAs are the unit of measure underpinning the NHS dental contract in England and Wales. Each course of NHS treatment is worth a defined number of UDAs — 1 UDA for a Band 1 examination, 3 UDAs for a Band 2 filling or extraction, and 12 UDAs for a Band 3 crown, denture or bridge. Every NHS-contracted practice has an annual UDA target negotiated with its commissioner (NHS England's regional team or, in Wales, the local health board), and the contract value at the practice is the UDA target multiplied by the practice's UDA value.
Practice-level UDA values vary materially across England — typically £25 to £35 in 2026, with some legacy or remote contracts higher. Hitting the annual UDA target matters: under-delivery leads to clawback at the year-end reconciliation, while over-delivery is unpaid above the contracted ceiling. For practice managers, UDA forecasting is one of the few financial KPIs that genuinely moves the year-end number, which is why most NHS-mixed practices track it weekly.
How an AI receptionist handles UDA on a call: a well-trained agent never quotes a UDA value to a patient (it's commercially confidential and not patient-facing) but does need to recognise the term when a visiting clinician or principal asks. Our agent routes any UDA-related caller — an associate dentist, a locum, an NHS commissioner — to the practice manager's mobile or voicemail rather than attempting to answer.
NHS Bands 1, 2 and 3
The NHS dental band system is the patient-charge structure for NHS dental treatment in England. Three bands cover almost everything a general dental practice does. Band 1 covers an examination, scale and polish, X-rays and preventive advice. Band 2 covers fillings, extractions, root canal treatment and most other restorative work. Band 3 covers crowns, bridges, dentures and other lab-made restorations. Each band has a single patient charge published nationally and updated annually each April. The 2026/27 charges are public on the NHS.uk website — confirm the current values when quoting.
Two important nuances: a course of treatment is charged at the highest band reached during the course (so a Band 1 check-up that becomes a Band 3 crown is charged once, at the Band 3 rate), and treatments started within two months of a previous course in the same band are usually free. Wales uses a similar three-band structure with different fees; Scotland and Northern Ireland have separate fee structures. Always confirm the patient's home nation before quoting.
How an AI receptionist handles bands on a call: our dental agent quotes the current England band charges from a configuration file we maintain centrally — when the April uplift lands, we update once and it ripples to every practice. The agent always names the band and the charge together ("a Band 2 treatment is £75.30 in 2026") and flags clearly when a treatment is private rather than NHS.
Recall
A recall is the patient's next routine examination interval, set by the dentist at the end of each check-up in line with NICE Clinical Guideline CG19. The guideline allows an interval of between 3 and 24 months for adults and 3 to 12 months for under-18s, based on individual oral-health risk and not on a fixed practice default. A patient with no caries risk, healthy gums, no medical complexity, and good plaque control may legitimately be recalled at 24 months. A patient with active periodontal disease, high caries risk, or complex medical history may need a 3-month recall.
For NHS-mixed practices, the recall interval also affects the UDA target: a 6-month recall generates twice the Band 1 UDAs of a 12-month recall on the same patient list. Some practices default to 6-month recalls for everyone; the GDC and NICE both flag this as inappropriate clinical practice. The recall date is normally written into the practice management system (Dentally, EXACT, SOE) and triggers an automated reminder around four weeks before the due date.
How an AI receptionist handles recall on a call: when a patient calls in response to a recall reminder, our agent looks up the patient in the PMS, confirms the dentist they normally see, offers two or three slot options consistent with the booked dentist's diary, and writes the appointment back to the PMS. For NHS recall, the agent also confirms whether the patient still qualifies for free NHS dental care (under-18, pregnant, certain benefits) before quoting a charge.
Urgent Dental Care (UDC)
Urgent Dental Care is the NHS pathway for patients needing dental treatment within 24 hours. Triggers include uncontrolled dental pain unresponsive to over-the-counter analgesia, dental trauma (a knocked-out tooth, a broken tooth with nerve exposure), uncontrolled post-extraction bleeding, or facial swelling localised to a tooth. A registered patient is normally seen by their own practice; an unregistered patient is routed to a UDC service, accessed via the practice, NHS 111, or NHS England's commissioning page.
The 24-hour clock matters. A patient in pain but not in clinical urgency (mild discomfort manageable with paracetamol) is offered the next routine slot, not a UDC slot. A patient with severe facial swelling spreading to the eye, the floor of the mouth, or the neck — or any swelling causing breathing difficulty — bypasses UDC entirely and is sent straight to A&E. Getting the triage decision wrong is a clinical-risk issue, not a customer service one. Out-of-hours UDC is commissioned regionally and accessed via NHS 111.
How an AI receptionist handles UDC on a call: our dental agent runs an NHS-aligned triage script on every "I'm in pain" call. It checks for red flags (facial swelling, breathing difficulty, recent trauma, anti-coagulant medication) before offering a slot. Red-flag callers are routed immediately to either the principal's mobile, the on-call dentist, or — for life-threatening swelling — instructed to call 999. A transcript and audio of every triage call is stored for clinical governance review.
Referral
A referral is the formal process of sending a patient from a general dental practice to a secondary care provider for treatment outside the GDP's scope. Common referral routes include orthodontics (NHS via the Index of Orthodontic Treatment Need for under-18s; private otherwise), oral surgery for complex extractions, periodontics for advanced gum disease, paediatric dentistry, restorative consultants, and community dental services for patients with special care needs.
Most referrals in England now go through electronic referral systems (the NHS e-Referral Service for community orthodontics, regional secondary care portals for hospital-based services, or direct private referrals via practice-management integrations). The referring GDP is responsible for the appropriateness of the referral, the quality of the supporting information (photographs, radiographs, periodontal charts), and the patient's understanding of why they're being referred. A poorly-evidenced referral often comes back with a request for more information, delaying treatment by weeks.
How an AI receptionist handles referrals on a call: our agent recognises common referral enquiries ("I've been referred to you by my dentist for orthodontics") and routes them to the appropriate diary — typically a separate orthodontic, oral surgery, or implant diary inside the same PMS. For patients asking about the status of their own referral out of the practice, the agent takes a callback request rather than guessing — referral status updates are clinical communication and shouldn't be improvised.
Sedation
Conscious sedation is the use of pharmacological agents to depress the central nervous system enough to make dental treatment tolerable, while keeping the patient responsive and able to maintain their own airway. Two routes are common in UK general practice. Intravenous (IV) sedation, typically with midazolam, is the workhorse for adult anxiety management and longer surgical procedures. Inhalation sedation (relative analgesia) with nitrous oxide and oxygen is the standard for paediatric and needle-phobic patients.
Both routes are tightly governed: IV sedation requires a sedationist (usually a second appropriately-trained clinician), pre-treatment ASA classification, fasting guidance, an escort to drive the patient home, and 24-hour post-treatment supervision. Sedation is available privately at most practices and on the NHS via referral for genuine clinical need (severe phobia, learning disability, complex surgery in a non-GA setting). The Society for the Advancement of Anaesthesia in Dentistry (SAAD) publishes the UK guidance most practices follow.
How an AI receptionist handles sedation on a call: our dental agent never books a sedation appointment cold. It recognises the request, captures the type of treatment and the reason for sedation, and routes the call to the sedationist's diary or to the practice manager for clinical screening. Pre-sedation fasting and escort instructions are sent only after a clinical screening call confirms the patient is suitable — blanket pre-instructions before screening risk inappropriate booking.
Private treatment
Private dental treatment is dental work paid for directly by the patient (or via a dental capitation plan such as Denplan or Practice Plan) rather than through the NHS. Most UK general dental practices are NHS-mixed: they hold an NHS contract and also offer private treatment to the same patient list. Private work includes treatments not available on the NHS at all (most cosmetic dentistry, tooth whitening, implants, Invisalign, composite bonding) and treatments a patient elects to have done privately for choice of materials, faster timing, or a specific clinician.
The General Dental Council requires clear, informed consent before any private fee is incurred. The patient must be told when a treatment is being recommended privately rather than on the NHS, given a written treatment plan with itemised costs, and offered an NHS alternative where one exists. Mixing NHS and private treatment within a single course of care is permitted but governed by strict rules — getting it wrong is one of the most common sources of GDC complaints. For practice managers, the private/NHS split is also the single biggest driver of practice profitability in 2026.
How an AI receptionist handles private enquiries on a call: our dental agent quotes private treatment fee bands ("a private composite filling is typically £180 to £240 at this practice") with the explicit framing that a written treatment plan will follow the consultation. For high-value private work — implants, Invisalign, full-mouth rehabilitation — the agent books a separate paid consultation rather than quoting on the call. That mirrors how the practice principals want these enquiries handled and protects the patient's right to a properly-evidenced treatment plan.
Want this depth in your AI receptionist?
Every term on this page is wired into the call flow we ship to UK dental practices. NHS UDA-band quoting from a centrally-maintained config; recall lookup against the PMS; UDC triage with NHS-aligned red flags; sedation routing to a clinical-screening diary; private fee quoting with a consent-first framing. Most generic AI agents handle perhaps two of these correctly. If you'd like to hear ours run through a Band 2 emergency triage and an Invisalign consultation booking on a live call, the demo is 15 minutes, no slides.
Frequently asked questions
How much is one UDA worth in 2026?
Practice UDA values are commercially confidential and vary across England — typically £25 to £35 in 2026, with some contracts higher. Confirm with NHS England's regional team or the practice principal.
Are NHS dental band charges the same in Scotland and Wales?
No. Bands 1/2/3 is the England structure. Wales has a similar three-band structure with different fees. Scotland and Northern Ireland use separate fee regimes. Always confirm the patient's home nation when quoting.
What's the difference between an emergency appointment and Urgent Dental Care?
Emergency appointments are the practice's own next-day slots. Urgent Dental Care is the NHS-defined 24-hour pathway. Severe facial swelling or breathing difficulty bypasses both and goes to A&E.
How long does an NHS recall last?
NICE guidance allows 3 to 24 months for adults and 3 to 12 months for under-18s, set by the dentist on individual risk — not on a fixed default. A healthy adult may legitimately be recalled at 24 months.
Can NHS dentists also offer private treatment?
Yes — most UK general dental practices are NHS-mixed. The patient must be told clearly when a treatment is private rather than NHS, given a written treatment plan, and offered an NHS alternative where one exists.
