Natural teeth whitening

With the need for teeth whitening these days, some which are expensive but there are also some which are affordable, people try to look for ways which are inexpensive, practical, effective, and natural.  Actually, it is indeed a good choice if it's naturally and physically healthy. There are ways, which would help make teeth beautifully and sparklingly white through natural teeth whitening.  It is a solution that one would probably be most comfortable and safe with, simply because other teeth whitening processes may somehow be dangerous.

Some of these natural teeth whitening ways can just be found at almost every one's house.  

Lemon juice,

its juice can be used like a toothpaste which is brushed on the teeth, and its peel can be used as a brush which is rubbed across the teeth, but, this common natural teeth whitening method is not a very good idea because its citric acid robs the tooth enamel of the needed calcium.  

Strawberries,

it's mashed into a pulp and used as a toothpaste, however like the lemon juice, is not a very good idea because of its acid.

Crunchy vegetables,

some common vegetables like celery, carrots, broccoli, and cucumbers act like a toothbrush. 

Wood ash or lye,

the hardwood's potassium hydroxide acts as a bleaching agent when brushed on your teeth, but this isn't a good method to practice because the potassium harms the tooth enamel.  

Baking Soda

 it's been used for a long time, together with salt, because it's an effective natural teeth whitening process, it even kills the bacteria causing plaque and the acids harming tooth enamel. 

 Peroxide

 it's brushed on the teeth like a toothpaste, but over-the-counter peroxides are not that effective as those dental teeth whiteners.  There's the combination of the peroxide and baking soda, this may be considered as the best natural teeth whitening remedy, if properly mixed and prepared.
