With time, as you get old, the enamel of the teeth starts to fade and this leads to discoloration of the teeth, which is also termed as stained teeth.
Here the teeth would appear to have a yellow stain on them along with evident marks on the teeth, especially with people who tend to smoke or consume a lot of nicotine.
However, there are plenty of home solutions and remedies available to handle this problem.
Here Are Amazing And Quick Remedies For Stained Teeth
1. Baking Soda
This is one of the highly recommended for people who have stained teeth that tend to get more yellowish with time. You have to take a bit of baking powder in your hand than use it like you use toothpaste.
Rub it well on the teeth on both the front and backside and let it stay for a while.
- Adding some water to the powder would help too.
- Now do this twice a day to get rid of the yellow stains from your teeth. 
2. Have Strawberries
Another sensible way of getting rid of the stained teeth problem would be munching on more strawberries. Strawberries are quite rich in a compound that would not only help in dissolving stains of the teeth but would also fight the enamel stains that happen with age.
Together they help in fighting this issue. You should ideally have about 6 strawberries a day to get the benefit but don’t forget to floss post it as the seeds may enter your molars. 
3. Orange Peel
This one is a bit odd but works. You are probably aware of the benefits of orange and lemon for lighting the skin. Now you can lighten your teeth’ color by rubbing the white side of the orange peel on your teeth.
Doing so regularly would help in removing the stained enamel problem and also provide you with whiter and shinier teeth. Plus this helps in combating other teeth problems too. 
4. Avoid Caffeine And Cola Drinks
Some foods make the stained teeth problem worse and these include caffeine along with cola drinks and also tea and coffee. These are foods that tend to leave a mark on your teeth and lead to eventual discoloration.

5. Quit Smoking
Quitting smoking is another great way to get rid of stained teeth. Remember that the nicotine that you have in the cigarettes is a major form of a problem when it comes to teeth discoloration or even stains.

7. Rinse Mouth After Meals
As a rule of thumb, make sure that you rinse your mouth every time after having something.
