This Treatment Is Not For Everyone
As popular as teeth whitening has become, one thing that needs to be remembered is that it cannot be used by everyone. This comes as a disappointment to many, as the natural reaction to seeing the results of a successful treatment is that most people will consider having it themselves. However, there are some people who cannot, and must not have the treatment – because even if it works for them, the side-effects will be of a negative kind and will potentially cause more harm than having no treatment at all.
People under the age of 16 cannot have teeth whitening surgery. The fact of the matter is that at this age the nerves of the teeth are enlarged, and any treatment of the nature of tooth whitening will irritate those nerves or cause them to become hyper-sensitive in the medium term. Without question, this will result in pain and can be damaging to the future health of the teeth. There is no point in having a bright, gleaming smile if you are in so much pain that you cannot flash it.
Additionally, pregnant women and those who are lactating should not have the treatment. The active ingredient of the tooth-whitening agent can be absorbed and, while harmless to adults, can be harmful to an unborn child if passed through the placenta or to a newborn if taken through feeding. Even in the case of over-the-counter treatment with a less powerful formula, it is advisable to avoid treatment until such time as a baby has been weaned so that the danger is absolutely zero.
