Coffee. Coffee alone is not harmful, but this changes when sugar and cream are added. A cup of coffee every day is enough to get to stain the teeth, so it is recommended to drink coffee alone or drink a lot of water to counteract its effects.
Citrus Exposure to citrus fruits such as lemon or orange can be harmful to teeth, as they erode the enamel and make them more susceptible to cavities and infections.
Alcohol. Alcohol itself is a harmful substance, but the effect it can have on the mouth is not well known. Drinking causes dehydration, and heavy drinking reduces saliva flow, leading to cavities and infections, and increasing the chance of developing mouth cancer.
Sticky foods. Sticky foods, such as dried fruits, can damage teeth, as they tend to stay in them for a long time after consuming them. Therefore, it is important to follow dental hygiene care after eating dehydrated fruits.
Sugary soft drinks Artificial soft drinks such as sugary and carbonated drinks are bad for teeth, because bacteria in plaque react by creating acids, which damage enamel. It is recommended to drink a lot of water after having a soda.
