Free dental clinical tools & calculators (UK)

Nosht offers free UK dental clinical tools and calculators for the whole dental team — dentists, therapists, hygienists, nurses and students. The four calculators below run in the browser with no login; each clinical reference also has a free answer guide. Everything is built for UK dentistry and organises published guidance for reference, not as clinical advice.

Free public calculators

Open, no login required. Deterministic reference calculators for everyday UK dental documentation.

BPE calculator — Convert a BPE score (0–4) into 2017 World Workshop / BSP UK periodontal staging and grading.
NHS dental charges & UDA calculator — Work out the England patient-charge band (1, 2, 3 or urgent) and the UDA value for a course of treatment.
Tooth notation converter — Convert any tooth between Palmer, FDI (ISO 3950) and Universal (ADA) notation, adult and deciduous.
GDC Scope of Practice checker — See what each GDC-registered dental role may and may not do, with direct-access and prescribing rules.

Clinical reference & decision-support

Plain-English answer guides paired with in-app decision-support tools. These organise published UK guidance for reference — they do not replace your clinical judgement, prescribing references or current guidelines.

One place for the calculations dentists reach for daily

UK dental documentation involves a handful of quick calculations and lookups that recur every clinic: turning a BPE screen into a periodontal stage and grade, banding an NHS course of treatment and reading off its UDA value, translating between tooth-notation systems, and checking who on the team is in scope for a given procedure. Each has a free Nosht calculator that follows the published thresholds exactly, so the answer is deterministic and reproducible.

Alongside the calculators sit clinical reference and decision-support tools — local anaesthetic maximum doses, drug interactions, paediatric dosing, periodontal staging and grading, GDC enhanced CPD, Montgomery consent, antibiotic prescribing and medical emergencies. Each has a plain-English answer guide that summarises the relevant UK guidance and an in-app tool that turns it into a structured prompt while you document. These organise guidance for reference; they support clinical judgement rather than replace it.

Frequently asked questions

What free dental tools does Nosht offer?

Nosht offers four free public calculators — a BPE calculator (BPE score to BSP staging and grading), an NHS dental charges and UDA calculator for England, a tooth notation converter (Palmer, FDI/ISO 3950 and Universal), and a GDC Scope of Practice checker by role. It also publishes answer guides and in-app decision-support tools covering local anaesthetic doses, drug interactions, paediatric doses, periodontal staging and grading, GDC enhanced CPD, Montgomery consent, antibiotic prescribing and medical emergencies.

Do I need an account to use the Nosht tools?

No. The four public calculators — BPE, NHS UDA, tooth notation and the GDC Scope of Practice checker — work in the browser with no login. The in-app decision-support tools (such as the LA dose tool and antibiotic guide) are part of the Nosht app and may require a free trial or subscription, but each has a free public answer guide you can read without signing in.

Are these tools clinical advice?

No. The calculators are deterministic and organise published UK guidance and classifications for reference. The dose, prescribing and consent tools are clinical decision-support — they support, but do not replace, your clinical judgement, current prescribing references and the source guidelines. Always confirm against current GDC, SDCEP, BNF/BNFc, BSP and Resuscitation Council UK guidance.

Are the tools UK-specific?

Yes. They are built for UK dentistry. The NHS charges and UDA calculator covers NHS England only; Wales, Scotland and Northern Ireland use different charging structures. The scope, consent and prescribing references follow UK guidance from the GDC, SDCEP and related bodies.

Can I use these tools as a dental hygienist or therapist?

Yes. The tools are for the whole dental team. The GDC Scope of Practice checker shows what each registrant title can and cannot do, and the periodontal, CPD and consent tools map directly to hygiene and therapy workflows.

These tools are for education and reference only — not clinical, prescribing or financial advice. The calculators are deterministic; the dose, prescribing and consent tools are decision-support. Always verify against current GDC, SDCEP, BNF/BNFc, BSP, NHS and Resuscitation Council UK guidance and use your professional judgement.
