It is important to be very cautious while eating, as there are food items which are bad for your teeth. Hence, it is best to avoid them. But if we cannot avoid them, we should at least brush our teeth after having those. Here goes the list:
Carbohydrates: No matter whether you are having brown rice instead of white rice and other healthy carbohydrates such as sweet potatoes and whole grain pasta, they will harm your teeth. This will happen because of the pre-digestive enzymes that will break the carbohydrates into sugar and hence harm your teeth. Also these foods can get stuck in between teeth and cause slow damage to the teeth.
Dark colored foods and drinks: These include sauces like soy sauce and even the fruits like cranberries and blueberries. The color gets absorbed by the enamel hence causing staining and eventual eroding of the enamel. Even red wine can have the same impact over the enamel as it contains alcohol and can make the enamel porous causing staining and eventual decay of the enamel. Even drinks such as coffee should not be consumed much as it also causes staining of the teeth. Also coffee being sticky in nature can get other foods stick on to the teeth.
Fresh citrus and dried fruits: Fresh citrus fruits such as lemons, oranges and grapefruits which are harmful for their colors as well as because of their acidic and concentration of sweets. Even if you are choosing sour fruits then also you are not doing any good to your teeth because of the high concentration of acids in the sour fruits. The dried fruits are equally harmful and that is because of the huge concentration of sugar. Another harmful agent present in the dried fruits is the non-soluble cellulose fiber that binds these fruits. This can bind the sugar around your teeth also.
Energy drinks and packaged fruit juices: All these drinks contain loads of added sugar. Hence it is better to have water or juices without added sugar for keeping your teeth healthy.
Vitamin tablets: It is surprising but it is true! Vitamin tablets that are chewable can get stuck within the teeth and beside the side teeth and are sometimes responsible for cavities. Hence after having chewable vitamins always brush your teeth.
Carbonated soft drinks: It is always better to stay away from carbonated soft drinks since they have loads of sugar in them. Other harmful ingredients that you can find in these drinks are phosphoric and citric acids. Both the acids can lead to the erosion of enamel.
Hard candies: According to the dentists, hard candies are not at all good for the teeth. These candies not only stick to the teeth but their taste remains in the mouth for a long time even after dissolving causing damage to the enamel.
Alcohol and medicines containing alcohol: For having healthy teeth, it is better to avoid alcohol. The reason is, alcohol decreases the saliva in the mouth and saliva helps to counter the harmful acids produced by the foods. Also, alcohol causes irritation of the soft tissues harming the teeth. If you need to have medicines which have alcohol in them and you can feel that your mouth is getting dried after having the medicine, get a fluoride gel for brushing your teeth or a fluoride rinse for increasing the saliva in your mouth.
