A UK-based dentist, Dr. Ferakh Hamid, revealed a surprising cause of yellow teeth that many overlook: brushing without wetting the toothbrush. According to Dr. Hamid, applying toothpaste to a dry brush can reduce the toothpaste’s effectiveness, as water helps spread the paste evenly and softens the bristles. This approach helps reduce irritation to gums and promotes better stain prevention. Without enough moisture, toothpaste doesn’t spread well and can make it harder to protect against yellowing over time.
Dr. Hamid also noted that brushing immediately after consuming acidic foods, such as tomatoes and citrus fruits, could damage enamel. Acid weakens the enamel, so brushing right away may wear it down further. He suggests rinsing with water after acidic foods or waiting a bit before brushing to allow the enamel to remineralize naturally.
Adding to this advice, Dr. Ezzard Rolle from Columbia University recommends holding the brush at a 45-degree angle to the gums for a thorough clean. While brushing twice a day is ideal, Rolle suggests aiming for at least one good brush before bed.
These tips emphasize the importance of both technique and timing in dental care, promoting a routine that reduces discoloration and maintains enamel strength.
