סודה או מיץ תפוזים: מה עשוי לפגוע בשיניים יותר? ד״ר גיל יוסף שחר (M.D) CategoryEducationPrivacy co

In this short Hebrew educational segment, Dr. Gil Joseph Shachar explains why 100% natural orange juice can be more harmful to teeth than soda, even though both beverages have a similar low pH (around 4). He introduces the concept of titratable acidity (TA) – the amount of base needed to neutralize all the acid in a liquid – and shows that orange juice contains a higher concentration of citric acid, giving it a greater TA than the carbonic acid in soda. Consequently, the total acid load that must be neutralized is larger for orange juice, making it more erosive to dental enamel. Dr. Shachar concludes that soda is the less damaging option for teeth and offers a practical tip: if one chooses to drink orange juice, use a straw to minimize contact with the teeth, thereby reducing the risk of erosion.
