Your orthodontist will tell you that high-sugar foods and sugary drinks can cause tooth decay. Also, eating starchy foods like french fries and rice will stick to the teeth for a long time and cause tooth decay. But there is a greater concern about acidic drinks such as soft drinks (diet and regular), sports drinks and juices which if consumed continuously or in large quantities over a period of time can cause tooth enamel to fall off.
Saliva is an effective factor in preventing tooth decay. You can also use saliva to help maintain oral hygiene. For saliva to do its job properly, you must allow it to expel acidic compounds from the mouth. For this purpose, it is best to change your eating habits and adjust the number of meals at longer intervals. During normal treatment, it is recommended that you adjust your meals to include three main meals and two snacks throughout the day. Also, drink plenty of water after every meal. These recommendations aim to give saliva a good opportunity to digest and clean the mouth, as well as the body to obtain the necessary vitamins and minerals during this period.
