Hard Candy
The majority of sweets are made using sugar and fat basis. The fat content of soft sweets is higher than that of hard candies (i.e., soft caramel has more butter and cream than hard caramels). But the hard candies have a lot more sugar, which is one of the reasons that make them harmful for your teeth. All of that sugar produces the ideal setting for cavities. Sugary also can add to plaque accumulation on your teeth, which may damage the enamel of your teeth over time, resulting in discoloration and cavities if not soon addressed.
Not only that, the pigments in hard candy, similar to the chromogens in red wine, can diminish your teeth' color and damage your teeth. To protect your oral health, you should skip the hard candies and choose sugarless gum to chew on instead.
