Side effect of teeth whitening
§  A range of toxic chemicals such as Hydrogen Peroxide and Carbamide Peroxide are mainly used by dentist as bleaching and disinfectant agents.
§  According to a report filed by the European Commission on tooth whitening products, it’s estimated that up to 25% of the hydrogen peroxide applied is actually SWALLOWED – and that’s NOT good for your health!
These toxic chemicals can cause side effects such as. 

Prolonged tooth sensitivity which can cause mild or severe pain. Exposures to a whitening agent can cause pain that may last as long as two weeks.

Stomach pain, Diarrhea & vomiting
The toxic chemicals used for whitening are harmful to the gastro-intestinal tract and can cause stomach pain, diarrhea and vomiting when swallowed. They should never be swallowed, but they are often swallowed.


Painful throbbing

Painful throbbing in the teeth may occur for several days after bleaching especially if the bleach penetrates any exposed part of the dentin or cracks in the enamel which can irritate the pulp. 
Note that this condition can cause the pulp chamber and the canal to be narrow and the consequence can be the need for a root canal.
