Dear Dentist(s), I'm doing this challenge called Plastic Free July and there are these challenges. One of the challenges is to replace your tube of toothpaste with a jar/make my own. After looking around I found a jar on Amazon called Viva Doria and it says all these great thing but they aren't a Doctor... so could a Dentist please share their opinion on the product (product details can be provided) or any alternatives that they would recommend to help me with my challenge. Sincerely, Dan Rhino
