In this week’s episode of Save Your Money, Save Your Teeth, Dr Clifford Yudelman sheds light on the silent but destructive impact of acid reflux on your teeth. Even without heartburn, stomach acid can creep up at night, silently eroding enamel and leading to long-term dental and health issues. We discuss how to spot early warning signs, distinguish reflux damage from other wear, and what lifestyle changes and treatments can protect your smile.

10 Questions with Summary Answers

(1:32 ) How does acid reflux cause tooth erosion when there are no symptoms?

Silent gastro-oesophageal reflux can occur without heartburn, especially during sleep. Stomach acid has a pH as low as 1.5, which quickly demineralises enamel. Reduced saliva flow at night makes the damage worse.

(4:24 ) Which tooth surfaces are most affected?

The inside (palatal) surfaces of upper teeth, biting surfaces of molars — especially lower molars — and gumline areas are most vulnerable, often showing “cupping” or crater-like wear.

(5:13 ) How do you tell reflux erosion from other types of wear?

Reflux erosion makes teeth look rounded and glazed. Grinding (attrition) creates flat, shiny surfaces, while over-brushing (abrasion) causes V-shaped notches at the gumline. A patient’s history and symptoms also provide clues.

(7:27 ) What warning signs can patients spot at home?

A sour or metallic taste in the morning, thinning or translucent tooth edges, new sensitivity (especially behind upper front teeth), or yellowing as enamel thins are all warning signs.

(8:49 ) How do you confirm reflux-related erosion in the clinic?

A 90-minute digital exam with 3D scans, time-lapse comparisons, and intraoral photos maps enamel loss over time. Patients are often referred to a gastroenterologist for confirmation and treatment.

(10:32 ) Is erosion in people with eating disorders the same as reflux erosion?

Yes. Frequent vomiting in conditions like bulimia exposes teeth to the same damaging stomach acid, often leading to severe erosion.

(11:35 ) What lifestyle and diet changes help reduce acid damage?

Eat earlier, avoid lying down for two hours after eating, limit acidic and carbonated drinks, sip water after acidic foods, elevate the head of the bed, maintain a healthy weight, and avoid tight clothing.

(13:14 ) Beyond brushing, how can you strengthen enamel against acid?

Chew sugar-free gum to stimulate saliva, rinse with water after acid exposure, and use products like tooth mousse (CPP-ACP) to remineralise enamel overnight.

(14:29 ) When should a dentist refer a patient to a gastroenterologist?

When erosion persists despite dental prevention, or if there are symptoms like chronic cough, throat irritation, acid taste, failed over-the-counter remedies, or cancer risk factors such as smoking.

(15:48 ) Can eroded teeth be restored without aggressive drilling?

Yes. Techniques include injection-moulded composite, resin-bonded overlays, minimally invasive onlays, and protective night guards to prevent further wear.

Acid reflux doesn’t just cause heartburn — it can quietly erode your teeth and impact your health. The sooner it’s detected, the more options you have to protect your smile. If you wake with a sour taste, notice sensitivity, or see changes in your teeth, book a 90-minute digital consultation at OptiSmile for a full scan, X-rays, and a tailored plan.
