Tea Tree Therapy Mint Toothpicks are made from birchwood infused with Tea Tree Oil and other natural extracts. Tea Tree Oil's natural antiseptic properties help freshen the breath and kill bacteria that causes plaque and tartar. Their long lasting flavor can be an aid to those giving up smoking and snacking. Everyone enjoys a flavored toothpick! They are great for freshening breath, cleaning teeth, and fighting off sweet tooth cravings. According to the Academy of General Dentistry, using a toothpick is fine when no other options are available and if you are very careful. But dentists don't recommend them for regular use. The problem? A piece of the wood can break off and get lodged in the gum tissue. It may seem hard to believe that they could be bad for you in any way. However, the truth is that frequently using toothpicks can damage your teeth and gums and lead to swallowing splinters and worse.
