    The OPTISMILE Podcast 114 - How to Read Your Own X-Rays (Co-Discovery)

    In this episode, Dr Clifford Yudelman introduces co-discovery, the principle that a patient is an informed partner in their own care rather than a passive bystander. He walks through how to make sense of a dental x-ray: what the light and dark areas mean, how cavities, bone loss, abscesses, tartar and dense restorations appear, and where AI tools such as Diagnocat fit in. The aim throughout is to replace fear with clarity, because when patients can see what is happening in their own mouth, they understand it, trust it, and act on it sooner. Questions and Answers Question 1.  What is co-discovery, and what should I be looking for on my own x-ray?  (1:04) Co-discovery, an idea from the American dentist Dr Bob Barclay in the 1950s, means the patient is an informed partner who understands the story their mouth is telling rather than diagnosing themselves. Start by orientating yourself: find the crowns, the roots and the surrounding bone. A healthy x-ray shows well-defined teeth and bone that hugs the roots closely, so once you know what normal looks like, abnormal findings make sense. Question 2.  What is the difference between the white areas and the dark areas on an x-ray?  (2:40) White areas are dense structures that block radiation: enamel, bone, and especially metal fillings or inlays. Dark areas are where the x-rays pass through easily, like the air between teeth, and they also flag less dense problems such as cavities or infection in the bone. With digital x-rays you can adjust the brightness to see these contrasts more clearly. Question 3.  How does a cavity look on an x-ray compared to a healthy tooth?  (4:34) A healthy tooth has a smooth, uniform outline with no dark shadows in the enamel, while a cavity usually shows as a dark triangle or shadow between the teeth or under an existing filling. Early decay can be subtle, and not all cavities show on x-rays, so the image only works alongside a clinical exam. Five shadows do not automatically mean five fillings. Question 4.  Can I spot bone loss on my own x-rays?  (6:02) Yes. In a healthy mouth the bone sits one or two millimetres below where the root meets the crown, so bone loss shows as a lowering of that level and a longer-looking root. Seeing it turns the abstract idea of gum disease into something visible, which makes patients far more likely to act. Question 5.  How do you spot an abscess or infection at the root tip?  (6:51) An abscess often appears as a dark circular or irregular area around the root tip, marking bone destruction from a chronic infection. Early ones can be missed on a flat 2D x-ray, which is why a CBCT often reveals a shadow that was not obvious before. Good diagnosis correlates the imaging with the symptoms, never a single snapshot. Question 6.  What do bright white streaks or shapes usually mean?  (7:42) Usually dense, man-made things: implants, crowns, posts and fillings, with white fillings slightly less opaque. A full crown can hide recurrent decay underneath, so we adjust how often we x-ray depending on how much restorative work is present. CBCT is excellent for roots and bone but is sensitive to metal, which is one area where AI helps cut through the streaking. Question 7.  How can I tell if there's tartar or calculus on an x-ray?  (9:18) Tartar is the chalky white build-up on teeth; above the gum it is mainly cosmetic and simply cleaned off. Below the gum it shows clearly on an x-ray, almost always alongside bone loss, and it is often invisible in the mirror, especially in smokers with healthy-looking gums. Seeing that hidden tartar and the bone it is destroying is what motivates people to act. Question 8.  Why do some teeth look like they're floating? Does it mean they're loose?  (10:41) A floating tooth has almost no bone around it, usually from very advanced gum disease in someone who has gone years without care. Most of these teeth cannot be saved. If two or three are floating, the rest are often not far behind. Question 9.  How does AI help patients understand their x-rays better?  (11:57) Software like Diagnocat colour-codes and flags abscesses, cavities and tartar, and even picks up wear or abfraction, supporting the conversation without replacing the dentist's judgment. Sometimes it catches what I would have missed, and sometimes I see what it missed. It has to be used responsibly, because turning up its sensitivity to claim a patient needs fifteen fillings is exactly the over-diagnosis to guard against. Question 10.  Why is it important for patients to see the x-ray, not just be told what's wrong?  (14:05) I take photos, a 3D scan and x-rays, run them through AI, then sit with the patient and look at everything together as part of a ninety-minute exam. This is discovering before diagnosing, and it lets us agree what genuinely needs treating and what can be left alone. Being told creates dependency, but seeing creates understanding, which helps patients accept care early while problems are still small. Closing Thoughts Co-discovery turns the abstract into the visible. When patients sit down and look at their own x-rays, photographs and scans alongside the dentist, decisions become shared rather than imposed, treatment is accepted earlier while problems are still small, and anxiety drops. Being told creates dependency; seeing creates understanding, and that understanding is what protects a patient's teeth, health and finances over a lifetime.

    The OPTISMILE Podcast 113 - Your Dental Emergency Kit

    Most of us never think about a dental emergency until we are far from a dentist: on holiday, at sea, or somewhere remote, and a tooth breaks or a filling drops out. In this episode, Dr Clifford Yudelman of OptiSmile talks through a simple dental emergency kit, covering what to pack, how to use it, and how to tell a genuine emergency from something that can wait. The aim throughout is buying time safely until you can reach proper care. Questions and Summary Answers 1. (1:27) What are the must-have dental items in a first-aid kit? A kit is about buying time safely, not replacing professional care. Pack a toothbrush and fluoride toothpaste, floss, orthodontic wax, temporary filling material, sugar-free gum, and basic pain relief in the form of Panado and ibuprofen. For toothache, two ibuprofen with each meal and two Panado in between will keep most pain manageable for three or four days until you reach a dentist. 2. (4:19) What is temporary filling material and how do you use it? It is a soft, mouldable putty that seals a lost filling or cracked tooth for a short time. Rinse and gently clear any loose debris, dry the area, then press the material into the cavity with a clean finger; it sets with saliva. It will not restore strength, but it reduces cold sensitivity, stops food packing in, and has a mild antibacterial effect. 3. (5:31) Can flying or diving make tooth pain worse? Yes. Pressure changes in flight, and more sharply when diving, can trigger tooth pain known as barodontalgia, which almost always signals an existing problem such as a deep filling, a hairline crack, or an untreated cavity. The best protection is a checkup before a long trip; if pain strikes, return to normal pressure, take ibuprofen or paracetamol, and avoid flying or diving again until the tooth is sorted. 4. (7:12) What should you pack if a crown or bridge falls out on holiday? Protect the exposed tooth and save the crown by rinsing it and storing it in a container or Ziploc bag, never wrapped in tissue. Temporary dental cement from a pharmacy, or even denture adhesive, can sometimes hold it in place. Never use super glue or household adhesives, as a misaligned crown can leave you unable to bite and can damage the gums. 5. (9:33) How do you store a knocked-out tooth? The best option is to put a knocked-out adult tooth straight back in, ideally within 20 to 30 minutes, after rinsing it gently with no scrubbing. If it cannot go back, store it in cold milk, Hank's Balanced Salt Solution, or inside the cheek; never use tap water, as the chlorine damages the root. Baby teeth should never be re-implanted. 6. (15:24) What painkillers are best for dental pain? A combination of ibuprofen and paracetamol, sold in the US as Advil and Tylenol, controls most dental pain well. Opioids such as codeine and morphine are rarely necessary and carry real risks. Antibiotics do not treat pain and should only be used where there are clear signs of infection and a clinician has prescribed them. 7. (16:49) Can orthodontic wax help with broken teeth, not just braces? Yes. A small piece of orthodontic wax pressed over a sharp edge eases a broken tooth, not just braces. You can even tuck a little inside a loose crown before pressing it back on; most squeezes out and the rest may help it hold for a while. 8. (17:34) Can a teabag stop bleeding after an injury? There is truth to it. Tea contains tannic acid, which helps a clot form, so a damp, cooled teabag squeezed out and held over the bleeding area for 15 to 20 minutes can help. Bite gently and remove it slowly without disturbing the clot, and call a dentist if bleeding follows an extraction, as you may have lost the clot. 9. (18:51) Can you pack antibiotics, or is that dangerous without a prescription? For seasoned remote travellers it can be sensible to carry antibiotics, but only with proper knowledge of when and how to use them. A dental infection needs a diagnosis, not guesswork, and pain alone does not mean an antibiotic is required. International guidelines strongly discourage unsupervised use because of the risk of antibiotic resistance. 10. (20:34) How do you tell a real emergency from one that can wait? Do not wait if you have facial swelling spreading towards the eye or under the jaw, a fever with dental pain, difficulty swallowing or breathing, uncontrolled bleeding, or a knocked-out permanent tooth. On a cruise, the ship's doctor can give antibiotics and call ahead to the next port. If pain is controlled with painkillers it can usually wait, but swelling, fever, or breathing or vision problems mean you should get help immediately. In Closing A few small items, a little knowledge, and a clear head can turn a holiday disaster into a minor inconvenience. Build your own dental emergency kit before your next trip, and have a checkup before you travel, particularly if you are flying long-haul or planning to dive.
