The OPTISMILE Podcast 77 - Sensitive Teeth & Erosion - The Health Habits Harming Your Enamel

Welcome to Save Your Money, Save Your Teeth, the podcast where dental expertise meets everyday health choices. Eon Engelbrecht of eRadio SA is joined once again by Dr Clifford Yudelman from OptiSmile in Sea Point, Cape Town.Today we’re tackling one of the most common but misunderstood dental complaints: sensitive teeth. We’ll explore why certain “healthy” habits — like hot water with lemon, apple cider vinegar, kombucha, sparkling water, or chewable vitamins — can actually erode enamel and trigger painful sensitivity.And if you’d like to dive deeper, you can read OptiSmile’s article Chilling Truths: Unveiling the Secrets of Tooth Sensitivity for extra insight.Summary (1:25) What does acid from lemon water or apple cider vinegar actually do to enamel and roots?Acid lowers the pH in your mouth below 5.5, dissolving minerals like calcium and phosphate from enamel. Roots are even more vulnerable since they lack protective enamel.🔗 See OptiSmile’s overview of Dental Problems and Solutions.(2:55) Does drinking hot acidic drinks make enamel damage worse?Yes. Heat speeds up acid’s effect and expands enamel crystals, making teeth even more vulnerable.🔗 Read more in Toothache Troubles: Managing Dental Pain and Costs.(3:34) Is a quick ACV or lemon shot better than sipping a diluted drink over an hour?A quick shot is harsh but brief. Sipping keeps teeth bathed in acid for longer, which is often worse. Rinse with water afterwards.(4:29) What about sparkling water or vitamin waters — do they erode enamel?Plain sparkling water is mildly acidic, but flavoured or vitamin waters can have a pH as low as cola, making them highly erosive.(5:43) What’s the difference between erosion, abrasion and abfraction?Erosion = chemical acid wearAbrasion = mechanical wear (toothbrush, nail biting)Abfraction = stress notches from clenching/grindingThey often combine, causing severe sensitivity.🔗 See OptiSmile’s guide on How to Deal with Teeth Grinding.(7:00) Does intermittent fasting with black coffee increase erosion risk?Yes. Coffee is acidic, saliva flow is reduced during fasting, and brushing straight after polishes away softened enamel.(8:25) Is swishing lemon water or kombucha before swallowing a hidden villain?Yes. Swishing spreads acid into every crevice and prolongs contact, like giving your teeth an acid bath. Best to swallow quickly and rinse with water.(10:10) Which is worst: chewable vitamin C, ACV gummies, electrolyte powders or sports drinks?Worst: chewable vitamin C (very acidic, pH ~2)Next: sticky ACV gummiesThen: electrolyte/pre-workout drinks (citric acid)Least harmful: plain sparkling water (in moderation)(11:47) How long does enamel stay soft after acid exposure?30–60 minutes. Brushing too soon removes minerals before saliva can reharden enamel.(12:35) If someone insists on lemon or ACV, what hacks reduce the damage?Use a strawRinse with waterDon’t brush for 30 minutesPair acidic drinks with mealsUse fluoride toothpaste or remineralising products🔗 See OptiSmile’s advice on Take-Home Teeth Whitening Kits – Explained, which also covers managing post-whitening sensitivity.That wraps up this episode of Save Your Money, Save Your Teeth.
