How to pass the ORE Paper B exam

  • Answer as a UK dentist would: SDCEP, NICE, FGDP(UK), BSP and Delivering Better Oral Health set the 'correct' answer, even where practice differs in your home country.
  • Law, ethics and health and safety are where overseas-trained dentists lose most marks. Learn consent (including Gillick competence and the Mental Capacity Act), the GDC's nine principles, IR(ME)R roles and HTM 01-05.
  • Learn the numbers that the guidance turns on: BPE codes, radiograph intervals by caries risk, fluoride ppm by age, IOTN grades and emergency drug doses.
  • Paper B's pass mark was 54.3% in August 2026, higher than Paper A's. Treat it as the harder paper and aim for 65% or more in timed mocks.

Sample questions with answers

These are the questions in the free test above, with answers. Try the test first. You'll learn more by getting some wrong.

1. Which root canal irrigant is the first choice in UK endodontic practice because it both dissolves organic tissue and kills bacteria?
Answer: Sodium hypochlorite. Sodium hypochlorite (typically 0.5% to 5%) is the only common irrigant that dissolves pulp tissue as well as being antimicrobial. EDTA removes the inorganic smear layer, chlorhexidine is antimicrobial but doesn't dissolve tissue, and saline does neither.
2. Which history most strongly suggests irreversible pulpitis?
Answer: Pain that lingers for minutes after a hot or cold stimulus, sometimes starting on its own. Lingering and spontaneous pain point to irreversible pulpitis. Short sharp pain that stops with the stimulus fits reversible pulpitis or dentine hypersensitivity. Pain on release of biting suggests a cracked cusp, and no response to testing suggests pulp necrosis.
3. Using the BSP implementation of the 2017 classification, a 40-year-old has periodontitis with 50% interproximal bone loss at the worst site. What is the grade?
Answer: Grade C. Grade is set from % bone loss ÷ age at the worst site: below 0.5 is grade A, 0.5 to 1.0 is grade B, above 1.0 is grade C. Here 50 ÷ 40 = 1.25, so grade C (rapid progression). Smoking and diabetes are risk factors recorded alongside, not needed for this calculation.
4. In the Basic Periodontal Examination (BPE), what does code 3 mean?
Answer: A probing depth of 3.5 to 5.5 mm: the black band is partly visible. BPE codes: 0 healthy, 1 bleeding, 2 retentive factor, 3 pocket 3.5 to 5.5 mm (black band partly visible), 4 pocket over 5.5 mm (black band disappears), and * for furcation involvement. Code 3 needs oral hygiene instruction, root surface debridement and a 6-point pocket chart for that sextant after treatment.
5. In complete denture construction, what is the normal freeway space (interocclusal rest space)?
Answer: 2 to 4 mm. Freeway space = resting vertical dimension − occlusal vertical dimension, normally about 2 to 4 mm. Too little (an increased OVD) causes pain, clicking teeth and a strained look; too much (a reduced OVD) gives poor appearance, reduced chewing efficiency and can contribute to angular cheilitis.
6. A partially dentate patient has lost all molars and second premolars on both sides of the mandible. Which Kennedy class is this?
Answer: Class I: bilateral free-end saddles. Kennedy Class I is bilateral free-end (distal extension) saddles. These dentures are tooth- and mucosa-borne, so they need careful design to control rotation, for example indirect retention and a well-extended saddle.
7. Following Delivering Better Oral Health (2021), what toothpaste advice should be given for a 2-year-old?
Answer: Use a smear of toothpaste containing at least 1,000 ppm fluoride, twice daily. For children up to 3 years, DBOH advises brushing twice daily with a smear of toothpaste containing no less than 1,000 ppm fluoride. From 3 to 6 years it's a pea-sized amount of more than 1,000 ppm. 5,000 ppm toothpaste is a prescription product for high-risk patients aged 16 and over.
8. A 12-year-old has an overjet of 10 mm with no other problems. What is the IOTN Dental Health Component grade?
Answer: Grade 5. IOTN DHC: an overjet over 9 mm is grade 5a (very great need). Over 6 mm up to 9 mm is 4a, over 3.5 mm up to 6 mm with incompetent lips is 3a, and over 3.5 mm up to 6 mm with competent lips is 2a. In the NHS, grades 4 and 5 qualify for treatment, and grade 3 does too if the Aesthetic Component is 6 or more.
9. A dentist sees an unexplained red and white patch on the lateral border of the tongue, consistent with erythroleukoplakia. What does NICE guideline NG12 recommend?
Answer: Refer urgently on a suspected cancer pathway (appointment within 2 weeks). NG12 asks dentists to consider an urgent referral (appointment within 2 weeks) for a lump on the lip or in the oral cavity, or a red or red and white patch consistent with erythroplakia or erythroleukoplakia. The lateral tongue is a high-risk site for oral squamous cell carcinoma.
10. A healthy patient returns 3 days after a lower molar extraction with severe throbbing pain and an empty, foul-smelling socket. What is the most appropriate management?
Answer: Irrigate the socket with warm saline, consider an antiseptic dressing and advise analgesics. This is dry socket (alveolar osteitis). It's managed locally: irrigation, an obtundent or antiseptic dressing if needed, and analgesia, with review. SDCEP is clear that antibiotics aren't indicated for dry socket in a healthy patient.
11. Under IR(ME)R 2017, who is responsible for justifying a dental radiographic exposure?
Answer: The IR(ME)R practitioner. The IR(ME)R practitioner justifies each exposure, weighing benefit against risk. The referrer supplies clinical information, the operator carries out the practical aspects, and the RPA advises the employer under IRR17. In general practice one dentist often holds all three IR(ME)R roles.
12. Following the FGDP(UK) Selection Criteria for Dental Radiography, how often should posterior bitewings be taken for an adult at high caries risk?
Answer: 6 months. FGDP(UK) advises 6-monthly bitewings for adults at high caries risk until there are no new or active lesions, then a longer interval: 12 months for moderate risk and 24 months for low risk. Every exposure still needs individual justification.
13. A 15-year-old attends alone and asks for a tooth to be restored. She understands the treatment, the alternatives and the risks. Under the law in England, what is the position on consent?
Answer: She can consent if she is Gillick competent, which she appears to be. A child under 16 who has enough understanding and intelligence to fully understand what is proposed (Gillick competence) can give valid consent. Encourage her to involve her parents, but her consent is valid without it. Record your assessment of her competence.
14. Under the GDC's Standards for the Dental Team, what must you do if something goes wrong with a patient's treatment and they suffer harm?
Answer: Be open and honest: tell the patient, apologise, offer a remedy and explain the likely effects. This is the professional duty of candour. The GDC expects you to tell the patient, apologise, offer an appropriate remedy or support to put matters right where possible, and explain the short- and long-term effects. Contacting your indemnity provider is sensible too, but it doesn't replace candour.
15. An adult patient develops wheeze, facial swelling and hypotension minutes after an injection. What is the first-line drug treatment recommended by Resuscitation Council UK?
Answer: 500 micrograms of 1 mg/mL (1:1,000) adrenaline intramuscularly. This is anaphylaxis. Give 500 micrograms (0.5 mL of 1 mg/mL) adrenaline IM into the anterolateral thigh for adults and children over 12, repeat after 5 minutes if there's no improvement, call 999 and give high-flow oxygen. IV adrenaline is for specialists only.

Certification guide

How to register with the GDC as an overseas-qualified dentist: Most dentists whose primary qualification wasn't gained in the UK or EEA must pass the [Overseas Registration Examination](https://www.gdc-uk.org/registration/overseas-registration-exam/about-the-ore) before they can apply to join the General Dental Council's register. The ORE has a written Part 1 and a clinical Part 2. If you pass each part first time it can take around six to 12 months, but demand for places is very high. Here's the full route and what it costs.
