Patient Script
For the friend playing the patient role
Character Overview: You are Winifred Ashcroft, a 72 year old retired florist. You ran a small shop in a market town for thirty years and you still arrange the flowers for your church. You live in a bungalow with your husband Leslie, who is 75 and a retired surveyor. Your daughter Carolyn lives about forty minutes away with her two children and phones most evenings. You are chatty, warm and a little apologetic, and you worry that you are wasting the doctor's time. When you are frightened you talk faster and your sentences run on. Eight years ago a scan showed thin bones and you started a weekly tablet. You have taken it faithfully ever since and no one has reviewed it since the start. Five days ago your dentist found an infected root under a cracked back tooth and wants it out. When he saw your medicines list he went quiet, said he would not take the tooth out until you had spoken to your GP, and mentioned a risk to the jaw bone. You went home frightened. You want to know whether you should stop the tablets before the tooth comes out, and whether you need them at all after eight years. You never use medical words for the jaw problem. You say things like "my jaw going bad".
Opening Sentence: "Hello, doctor. Sorry to bother you. I've got a tooth that has to come out, but my dentist says he won't do it until I've spoken to you about my bone tablets. He said something about my jaw, and I haven't slept properly since."
History if Asked (Data Gathering Phase)
- ●The tooth: "It's a lower back tooth on the left. I cracked it on a nut in a flapjack about two months ago. It's been aching on and off since, and it throbs at night sometimes. Paracetamol takes the edge off."
- ●Swelling, pus, fever: "Two weeks ago I had a little swelling on the gum and it burst with a nasty salty taste. It's flat today. No swelling on my face, no fever, I'm eating all right on the other side, and swallowing and breathing are fine."
- ●What the dentist found: "He took an X ray five days ago. He said there's an infection at the root and the tooth can't be saved. He's booked me in ten days from now. He said it's just the one tooth."
- ●What the dentist said about the tablets: "He asked what medicines I take and when I said alendronate he went quiet. He said there's a small risk the jaw bone doesn't heal after an extraction and he wants my doctor to say it's all right. He said he'd like it in writing."
- ●The tablet: "Alendronate, one a week, 70 milligrams. I've taken it for eight years. I take it first thing on a Saturday with a full glass of water, sit upright for half an hour and have breakfast after. I've only missed it two or three times, once on holiday."
- ●Why it was started: "I had a scan when I was 64 because Mum had a terrible stoop in her eighties. It showed thin bones and the doctor then started the tablet. I've never broken anything."
- ●Reviews since: "Nobody has ever said it needs looking at again. I get it on repeat every three months. I've never had another scan."
- ●Fractures, height and back: "No fractures, not even a wrist. I think I've shrunk about an inch since my fifties. My back aches a bit if I've been gardening, nothing sudden."
- ●Falls: "None in the last year. I tripped over a hosepipe two years ago and landed on the grass, no harm done."
- ●Side effects of the tablet: "No heartburn, no trouble swallowing. No pain in my thighs, hips or groin, and nothing in my ears."
- ●Mouth and teeth: "I go to the dentist every six months and have done for years. I've a bridge on the upper left that fits well. Gums are fine. I clean my teeth twice a day. No loose teeth, no numbness, no sore patches."
Ideas, Concerns, Expectations
Gating note: Winifred does not raise any of the following herself. Each part comes out only when the doctor asks what she thinks is going on, what is worrying her, or what she was hoping for.
- ●Ideas: She thinks the tablets may have built up in her bones over the years and could make her jaw go bad if a tooth is pulled. She has also heard they only work for five years, so she wonders whether eight is too long. "I read that they stay in your bones for ever. Is that why he's worried?"
- ●Concerns: Her main fear is that her jaw will not heal, or will go bad, and she will be left in pain. Her second fear is of stopping the tablets and ending up stooped like her mother, who could not see over the steering wheel at the end. "If I stop, will my back go the way Mum's did? I couldn't bear that."
- ●Expectations: She came expecting to be told whether to stop the tablets before the extraction, and for the doctor to write to the dentist so the tooth can come out on the day. She would also like to know if she needs the tablets any more. "Should I stop them? And can you write to him, because he was very firm about that."
If Asked: Medical History and Medications
Gating note: Winifred answers each of these plainly when the doctor asks about it.
- ●Other health problems: "Blood pressure, controlled with the amlodipine. Nothing else. No diabetes, no kidney trouble, no thyroid."
- ●Medicines: "The amlodipine, the alendronate and a calcium and vitamin D tablet once a day. Nothing from the chemist apart from paracetamol for the tooth. No steroid tablets, no inhalers, no steroid creams."
- ●Cancer, chemotherapy or radiotherapy: "No, never. No treatment to my head or neck."
- ●Calcium in the diet: "Cheese and yoghurt most days, and milk on my cereal."
- ●Allergies: "None."
- ●Menopause: "At 51, nothing unusual. I had no hormone treatment."
- ●Family: "Mum had the stoop and shrank. Nobody in the family has broken a hip."
- ●Smoking and alcohol: "I smoked about ten a day from my twenties until I was 45, and I stopped. A glass of wine at the weekend, no more."
- ●Mood: "I'm cheerful, but I've been fretting about this."
Social History and Lifestyle Impact
- ●Home: Lives with Leslie in a bungalow. He drives too and would take her anywhere she needed to go.
- ●Activity: Walks the dog for about forty minutes every day, gardens, and goes to a chair exercise class once a week. Leslie plays bowls twice a week.
- ●Weight: About ten stone and has always been slim.
- ●Availability: Retired and free almost any day. She can get to the hospital or the surgery easily.
- ●The dentist: She has been with the same NHS practice for fifteen years and trusts them. The extraction is booked for ten days from now and she is dreading it.
If Asked: Associated Symptoms
Gating note: Winifred answers these only when asked. Every one is negative unless stated.
- ●If asked about thigh, hip or groin pain: "No. My legs are fine."
- ●If asked about a swollen face, trouble opening the mouth, fever or feeling unwell: "No. I feel well in myself."
- ●If asked about numbness or tingling in the lip or chin, a bad taste that does not go, or loose teeth: "No, only that one salty taste when the gum burst."
- ●If asked about indigestion, burning in the chest or pain on swallowing: "No, never had a bit of trouble."
- ●If asked about severe back pain or a sudden loss of height: "No. Just the inch over many years."
- ●If asked about weight loss, night sweats or cough: "No, none of that."
Responses to Management (The Negotiation Phase)
- ●If the doctor says the extraction can go ahead and the tablets do not have to be stopped:
- ●Reaction: Surprised and relieved. "So I don't have to stop them? The way he said it, I thought I was walking into a minefield." She asks how likely a problem is. "Has eight years made mine worse than other people's?" She accepts a balanced answer: "So it's small, but he's right to be careful."
- ●If the doctor suggests stopping the tablets before the extraction, or does not say whether to stop:
- ●Reaction: Agrees too readily. "Oh, I'd rather stop them, just in case. Stop today then?" If the doctor then explains why stopping before the tooth does not help, she is puzzled but listens: "Even with the tooth coming out? I'd have said that was exactly when you'd stop."
- ●If the doctor raises reviewing whether she needs the tablets after eight years, or arranging a scan:
- ●Reaction: Interested but nervous. "Nobody has ever checked. Do I have to come off?" She asks what happens if the scan is good. "Would I stop then? Will my bones go the way Mum's did?" She is reassured to hear that nothing is decided today and any decision comes after the scan: "Right, so the tooth first, then the scan, then we decide together. I can do that."
- ●If the doctor offers to write to the dentist, or says he does not need permission:
- ●Reaction: Practical. "He was very firm that he wanted it in writing." She asks what the letter will say and whether she can have a copy. "I'll take it in myself if that's quicker. Can I see it first?"
- ●If the doctor talks about the infected tooth, painkillers or what to watch for afterwards:
- ●Reaction: Wants specifics. If told only to "come back if you're worried": "Worried about what, exactly? What would be a proper problem?" She repeats back clearly when given specific warning signs and who to ring. She asks whether she will need antibiotics. "He didn't say anything about those."
- ●If the doctor gives a view on the outlook:
- ●Reaction: Asks plainly. "Will my jaw heal? Will it hurt?" Reassured by a calibrated answer: "Right. Small chance, and I know what to ring about. That's better than I thought."

Clinical Learning Points
The core dilemma and the model plan
- ●Winifred has taken alendronic acid for eight years with no fracture and has been told by her dentist that she needs medical clearance for an extraction. Two separate questions hide in the consultation: is the extraction safe, and does she still need the tablet. Candidates often answer the second when asked the first.
- ●The model plan: tell her the extraction can go ahead and that she should keep taking the tablet through it; give the dentist the facts they need; do not prescribe antibiotics just for the jaw risk; then, as a separate planned step, review eight years of treatment with fracture risk reassessment and a DXA (dual energy X ray absorptiometry) scan, with the continue or pause decision made with her afterwards.
- ●Alternatives that also pass: ringing the dentist rather than writing, doing the DXA and bloods before or after the extraction, asking the dentist or an oral surgeon for advice, or asking a local bone health service to take on the review. Stopping treatment for good today, or refusing to support the extraction, does not pass.
Osteonecrosis of the jaw (ONJ) and oral bisphosphonates
- ●ONJ is exposed or dead bone in the jaw that persists beyond about eight weeks (CKS, Osteoporosis prevention of fragility fractures, last revised April 2025). It is rare with oral bisphosphonates for osteoporosis. The MHRA and BNF note the risk is substantially greater with intravenous bisphosphonates for cancer.
- ●The SDCEP (Scottish Dental Clinical Effectiveness Programme) 2024 supplement gives an incidence of under 0.05 percent for osteoporosis, and its patient leaflet quotes between 1 in 1000 and 1 in 10,000. Quote these as small, not zero.
- ●Recognised risk factors in the MHRA and BNF text include potency and route of the drug, cumulative dose and duration, steroids, smoking, poor dental health and cancer. Winifred has the duration and an infected tooth, and none of the others.
- ●The tooth matters as well. An untreated infected root is itself a risk to the jaw and to her, so leaving it in place is not the safe option.
What the dentist's guidance says
- ●SDCEP "Oral health management of patients at risk of MRONJ" (2017, reviewed and still current in March 2024) places a patient on a bisphosphonate for more than five years in the higher risk group. For higher risk patients the dentist should explore alternatives to extraction where a tooth can be kept, for example by retaining roots when there is no infection. If extraction remains the best option, the dentist proceeds as for low risk patients.
- ●Her tooth is infected and cracked, so extraction is the reasonable option. The same guidance says not to prescribe antibiotic or antiseptic prophylaxis specifically to reduce MRONJ risk (antibiotics for the dental infection itself remain the dentist's decision), to give the patient advice on reporting symptoms, and to review healing; if the socket has not healed by eight weeks and MRONJ is suspected, the dentist refers to an oral surgery or special care dentistry service.
- ●The patient leaflet states plainly that people should continue their medicine and that the benefit is likely to outweigh the risk. UK dental guidance does not ask for a drug holiday before an extraction, and does not make GP permission a prerequisite (SDCEP leaves the decision with the dentist, who may seek specialist advice). Some international guidance allows an interruption to be considered in selected higher risk patients, so a candidate who asks a specialist for advice rather than stopping outright can still pass. What the dentist does need is the drug, dose, duration, steroid use and cancer history. A short letter or call giving those facts, and saying the surgery supports continuing, resolves the impasse.
Reviewing eight years of treatment
- ●NICE NG259 (Osteoporosis: risk assessment, published July 2026, updating CG146) covers who to assess, how to assess risk and when to start treatment, and it covers repeat risk assessment only for people not having treatment. It does not set out how long to continue a bisphosphonate or when to take a break, so for duration use CKS and NOGG (National Osteoporosis Guideline Group, updated December 2024) advice. NICE has said its planned next update will cover treatment monitoring and pauses.
- ●CKS says to reassess the need for continued oral bisphosphonate after five years. Treatment should continue for at least ten years in people who were 70 or over when they started, who have had a hip or vertebral fracture, or who fracture during the first five years of treatment. NOGG 2024 adds people on oral prednisolone of 7.5 mg a day or more; Winifred takes no steroids.
- ●Winifred started at 64 and has had no fracture, so she falls outside those groups. CKS advises a DXA scan. If the T score is minus 2.5 or lower, consider continuing for another five years and reassess; if above minus 2.5, consider a pause of 1.5 to 3 years and reassess.
- ●The review was overdue and nobody noticed. Repeat prescriptions that run for years without a review are a continuity of care failure, and the fix is a review date on the record.
Fracture risk, bloods and the pause
- ●Before the review check adherence, how the tablet is taken, calcium intake, vitamin D, kidney function and calcium, other causes of bone loss, falls and lifestyle. Her recent eGFR of 71 and good dietary calcium are reassuring.
- ●If a pause is chosen, CKS advises reassessing fracture risk after two years for alendronate, or sooner if she fractures or her risk factors change, and restarting treatment if a new fracture occurs. The effect of alendronate persists for some time after stopping, which is why a pause is an option and why a fear of an immediate stoop is not justified.
- ●Continuing or pausing are both defensible; what matters is that the choice is made from a reassessment, not from the dental problem or from habit.
Other adverse effects after long treatment
- ●Atypical femoral fractures are rare but are linked to long term bisphosphonates, mainly alendronate. CKS advises asking about new thigh, hip or groin pain. If it occurs, stop the drug and arrange an X ray of the femur; the MHRA advises considering discontinuation once an atypical fracture is suspected.
- ●Oesophageal reactions need prompt review if there is difficulty or pain on swallowing, or new or worsening heartburn. Winifred takes the tablet correctly, which keeps the risk low.
- ●Rare ear canal osteonecrosis is a further consideration if she develops chronic ear symptoms.
Communicating with her
- ●Take her jaw fear seriously, then place it in proportion. A figure such as 1 in 1000 to 1 in 10,000 is more useful than "very rare", and it also explains why the dentist was careful.
- ●Answer her instinct to stop the tablet. She thinks it is the cautious choice, but stopping does not reduce the jaw risk quickly and it removes protection for her bones. Explain that the review is about her bones now, not her mother's.
- ●Make the plan sequential, with the tooth first, then scan and bloods, then a joint decision. Give specific warning signs in everyday words, check she can say them back, and agree what is in the letter.
Safety netting and follow up
- ●To the dentist: jaw pain, numbness or tingling, loose teeth, a persistent bad taste, pus, swelling or exposed bone, and a socket not healed by about eight weeks.
- ●To the surgery: new thigh, hip or groin pain, difficulty or pain swallowing, or heartburn that is new or worse.
- ●Arrange a review after the DXA and bloods, annotate the repeat prescription with a review date, and record the discussion and the advice given to the dentist.
Common mistakes in this station
- ●Telling her to stop alendronic acid before the extraction, or stopping it altogether today because she asks.
- ●Saying the extraction should be delayed or avoided because of the tablets, when the infected tooth needs treating.
- ●Prescribing antibiotics purely to prevent a jaw problem.
- ●Answering the dental question and never noticing that eight years of treatment has gone without a review.
- ●Deciding to stop or continue indefinitely without a DXA and fracture risk reassessment.
- ●Quoting NG259 as the source for treatment duration, when it addresses risk assessment.
- ●Giving no jaw or thigh warning signs, or sending her away with a plan she cannot describe.
