Ways to protect teeth from cavities include paying attention to oral hygiene, adjusting daily diet, and consuming fluoride in moderation.
1. Oral hygiene: Pay attention to oral hygiene in daily life, rinse your mouth in time after meals, brush your teeth in the morning and evening on time, and master the correct way of brushing to keep your mouth clean.
2. Adjustment of daily diet: Daily diet should be adjusted to minimize the consumption of sugary foods, less acidic and stimulating foods, do not eat too much hard food, and avoid eating before going to bed.
3. Adequate intake of fluoride: you can drink fluoridated water, or apply topical fluoride, and people over 6 years old can use fluoridated toothpaste to avoid tooth decay caused by excessive fluoride deficiency.
In addition, you should go to the doctor for regular oral checkups in your daily life, and when you find that there are cavities, you should have them treated in a timely manner.
