Final Thoughts on Listerine Whitening Pen
Using the pen to apply the whitening to teeth has been found to be difficult for some users. Others have complained that when the solution touched their gums, it burns immediately and continue to burn even after it has been rinsed clean. This is due to the hydrogen peroxide which does lighten teeth but is also extremely potent and affects the gums and other oral tissues.
The pen has produced better results for users who smoke or drink coffee and tea as the active ingredients targets these stains more effectively. Overall, the Listerine Whitening Pen is recommended for those with teeth discoloured by tobacco, coffee, tea and other food sources more than for those with natural, gradual discoloration.
This product gives immediate, short-term, temporary effect. Go to the dentist and have your teeth professionally cleaned prior to application. Even at that, the effects are only temporary, lasting less than one week.
