Tooth decay is a common problem, affecting nearly half of the population worldwide. Did you know that apart from poor oral hygiene, your diet also play a vital role when it comes to tooth decay? Here we will provide you with 7 tips on how to prevent your tooth from decaying. 


1. Consume more calcium. Calcium is required in the remineralisation of your teeth, which in turn decreases your risk of tooth decay. Cheese, milk, yogurt and broccoli are good dietary sources of calcium.


2. Eat more nuts. They are rich in protein, calcium and phosphorous, which protect your teeth’s enamel. Due to their crunchy texture, chewing on them helps promote the production of saliva (saliva is essential to eliminate bacteria and plaque from the surface of your teeth). This helps to cut down your risk of tooth decay.


3. Increase your intake of high-fiber fruits and vegetables. The large amount of fiber in apple, carrot and celery for instance, triggers saliva flow, which cleans your teeth effectively and prevents tooth decay.


4. Say no to sugary food and beverages. Oral bacteria use the sugars from your food and drinks to produce acid, which destroy your teeth’s enamel, causing tooth decay. As such, you should stay away from sugar-laden food and beverages. Also, avoid sucking on hard candies and sipping sugary drinks throughout the day since this will lengthen the time where your teeth is exposed to acids.


5. Quit smoking and reduce your alcohol intake. Tobacco and alcohol lower your saliva flow. As a result, this elevate your chances of tooth decay.  


6. Brush your teeth two times a day using a fluoride toothpaste and floss daily.


7. Replace your toothbrush every three months. Frayed bristles decrease the effectiveness of plaque removal.
