Dr Niyi Adekeye, a dentist on Thursday warned against the use of charcoal, baking soda, potash and salt for teeth whitening, stating that this could affect some vital organs of the body.
He told News Agency of Nigeria, NAN, in Lagos that instead of engaging in such act, medically certified methods such as teeth bleaching was ideal.
According to him, the use of charcoal could cause damage to the kidney and the heart while the intake of salt and potash should not be excessive.
Teeth bleaching is recommended for people who want their teeth white and this does not require any form of surgery, it is a simple process and has no negative implications.
According to the Dentist, a certain patient who was suffering from toothache used his urine to gargle for pain relief and cure; and after a while his condition became worse.
