Teeth whitening products
Recently, while viewing photos Olivia was tagged in a photo on Facebook and noticed that
her teeth, by comparison, were becoming quite discoloured. She decided she needed to do
something about this quickly, feeling somewhat embarrassed about it and knowing there
would be more pictures posted in the future.
Olivia was aware of some over-the-counter products she could use, such as “Pearl Drops”
that were relatively cheap, and that she could also have her teeth whitened at the dentist,
but this was expensive. Being a health care worker, Olivia thought that there could also be
side effects to whatever treatment she decided on and she wasn’t sure how effective either
treatment was. Consequently, she decided she needed to look into this in more depth.
