Here are five best things that will help keep your pearly teeth shiny.

   Apples

Though apples technically have sugar, they’re not quite in the same type as a candy. Apples are high in fiber(纤维) and water, which are both key parts in removing food remains from your teeth. The biggest advantage, however, is the quality of the apple, and the fact that you have to bite so much to break it down enough to eat. And that act of biting produces saliva(唾液) that can help to protect your teeth from sugar and other harmful things that often cause tooth problems.

Cheese

Cheese, along with other milk products have bacterium that have been found to raise the PH levels inside your mouth, and in turn, lowering their risk of tooth problems. Cheese also has calcium (钙)and protein that help strengthen teeth.

Leafy Greens

It’s true that leafy greens like cabbages and many more will likely find their way on any lists of healthy foods. This is because they are full of healthy vitamins and minerals while being low in calories. Specifically for teeth, however, these green vegetables are high in calcium to help build good enamel(釉质).

Almonds （杏仁）

Almonds are fantastic for your teeth because they contain calcium, protein, and like the leafy greens, they are also low in sugar. They also require quite a bit of biting to break down, adding to the production of that all-important saliva.

Water

Water contains fluoride（氟化物）that is a mineral which has been known because of its teeth strengthening powers. And when there is plenty of fluoride in your drinking water, it can do a wonderful job like that.

So if you want to own healthy and shiny teeth, keep having them often.
