A patent has recently been released by LG Household and Health Care Ltd entitled ‘Preparation for Attaching to Teeth or Surrounding Part of Teeth’.
There are many difficulties involved with delivering an active ingredient into the oral cavity as the contact time and quantity play an important role. As outlined in the patent, there are disadvantages to existing delivery methods. The new preparation delivers an active ingredient whose physical properties are changed before attachment to teeth and after a period of time after the attachment.
